Palliativpatienten im weit fortgeschrittenen Krankheitsstadium

BACKGROUND: Prehospital emergency teams will be confronted with the specific needs of resuscitation in palliative patients in whom a return of spontaneous circulation (ROSC) could be found significantly less frequently than in other emergency situations. The present investigation aims to show medical and judicial problems related to cardiopulmonary resuscitation (CPR), external examination of the corpse and death certification. METHODS: Over a 12-month period all emergency cases involving physicians in an out-of-hospital resuscitation setting in cancer patients were retrospectively analysed for indications for emergency call, situation on-site and prehospital treatment by emergency physicians, external examination of the corpse and determination of death. RESULTS: For the period mentioned 164 (2.7% of the total) emergency calls by cancer patients or their relatives were identified. In the following study 43 patients (26.2%) could be included. In 20 cases (46.5%) the emergency physicians attempted to resuscitate the patient by performing CPR. In the majority of cases (36; 83.7%) death certification and external examination of the corpse were necessary at the scene. CONCLUSIONS: Due to a reduced rate of ROSC in palliative patients, death certification and external examination of the corpse are more often necessary than in other emergency situations. Therefore every emergency physician should be familiar with the ethics of resuscitation of patients in palliative care and with external examination of the corpse to do justice to patients and their caregivers.     

Auf der Grenze: präklinische Wiederbelebung im hohen Alter

Epidemiologic data suggests that emergency medicine will be increasingly affected by the aging population. Since death is more common among the elderly emergency physicians and paramedics more often will encounter patients experiencing cardiac arrest. In elderly patients cardiac arrest might be not a sudden event but the end of the process of dying and to withhold or to abandon CPR might be appropriate. Can we define patients with no chance of survival? Recent studies suggest that age is associated with survival, being lower among the elderly. In particular in nursing homes the benefits of resuscitation attempts are very limited. However, age seems to be only a relatively weak independent predictor of outcome. If there is any doubt about the appropriateness of resuscitation attempt, standard of care remains prompt initiation of CPR. Decisions to withhold CPR should be based on sound clinical reasons. Since patients have a right to refuse treatment, their preferences should be taken into account. The probability of survival might influence patients’ preferences. Patients should be encouraged to determine in advance whether resuscitative efforts should be initiated and these decisions should be written down. This enables the emergency personnel to consider the patients’ individual hierarchy of values.     

Cardiopulmonary resuscitation after traumatic cardiac arrest is not always futile

INTRODUCTION: The use of guidelines regarding the termination or withholding of cardiopulmonary resuscitation (CPR) in traumatic cardiac arrest patients remains controversial. This study aimed to describe the outcomes for victims of penetrating and blunt trauma who received prehospital CPR. METHODS: We conducted a retrospective review of a statewide major trauma registry using data from 2001 to 2004. Subjects suffered penetrating or blunt trauma, received CPR in the field by paramedics and were transported to hospital. Demographics, vital signs, injury severity, prehospital time, length of stay and mortality data were collected and analysed. RESULTS: Eighty-nine patients met inclusion criteria. Eighty percent of these were blunt trauma victims, with a mortality rate of 97%, while penetrating trauma patients had a mortality rate of 89%. The overall mortality rate was 95%. Sixty-six percent of patients had a length of stay of less than 1 day. Four patients survived to discharge, of which two were penetrating and two were blunt injuries. Hypoxia and electrical injury were probable associated causes of two cardiac arrests seen in survivors of blunt injury. CONCLUSIONS: While only a small number of penetrating and blunt trauma patients receiving CPR survived to discharge, this therapy is not always futile. Prehospital emergency personnel need to be aware of possible hypoxic and electrical causes for cardiac arrest appearing in combination with traumatic injuries.     

Ethische Konflikte in der Notfallmedizin

Objective: Thirty years ago, cardiopulmonary resuscitation (CPR) was primarily developed for otherwise healthy individuals who experienced sudden cardiac arrest. Today, CPR is widely viewed as an emergency procedure that can be attempted on any person who undergoes a cessation of cardiorespiratory function. Therefore, the appropriateness of CPR has been questioned as a matter of the outcome, the patient’s preferences, and the cost. The objective of this article is to analyse ethical issues in prehospital resuscitation. Arguments: CPR is bound by moral considerations that surround the use of any medical treatment. According to Beauchamp and Childress, the hierarchy of justification in biomedical ethics consists of ethical theories, principles, rules, and particular judgements and actions. The decision to start CPR is based on the medical judgement that a person is suffering from circulatory arrest. The decision is justified by the moral rule that the victim of a cardiac arrest has the right to survive and to receive CPR. Moral rules are more specific to contexts and are based on ethical principles. The principle of beneficence means the provision of benefits for the promotion of welfare. Talking about beneficence in resuscitation means once again reporting stories of success, as many victims of pre- and in-hospital sudden death have been saved in the past. Nevertheless, resuscitative efforts still remain unsuccessful in the majority of cases, involving the principle of nonmaleficence. There is potential harm in CPR. Survivors may recover cardiac function, but sustain severe hypoxic brain damage, at worst surviving without awakening for months or years. In particular, post-traumatic CPR is associated with an extremely poor outcome, leading to the issue of futility. However, futility should be defined in a strict fashion, as there might be an individual chance of survival. The principle of respect for autonomy means the right of a patient to accept or reject medical treatment, which continues in emergency conditions and after the patient has lost consciousness. The time frame in CPR requires medical decision-making within seconds, and CPR is usually initiated without the patient’s involvement. If the patient’s wish’s can be ascertained later on, life-sustaining therapies might be withdrawn at that time. Terminally ill but still competent patients should be encouraged to write a no-CPR document, which does not deny patients relief from severe symptoms, but might facilitate withholding resuscitative efforts at the scene. The principle of justice affects priorities in the allocation of health care resources. The decision made for a particular patient might delay or prevent emergency treatment in other patients who could receive greater benefit. Conclusions: The standard of care remains the prompt initiation of CPR. However, ethical principles such as beneficene, nonmaleficence, autonomy, and justice have to be applied in the unique setting of emergency medicine. Physicians have to consider the therapeutic efficacy of CPR, the potential risks, and the patient’s preferences.     

In-hospital resuscitation

A recent world expert conference on resuscitation and emergency cardiac care led to evidence-based international guidelines for cardiopulmonary resuscitation (CPR). Several changes to CPR interventions were recommended, and will have to be implemented into clinical practice. The poor prognosis of patients who suffer in-hospital cardiac arrest may be improved with developments in CPR interventions. In the present review the most important changes recommended by the new CPR guidelines and the latest promising CPR investigations are described, focusing on their impact on in-hospital resuscitation.     

Notfallmedizinische Betreuung von Palliativpatienten am Lebensende

Background

The treatment of out-of-hospital palliative emergency care situations during cardiac arrest is a special situation. The prehospital emergency physician (EP) and the paramedic must be informed about the medical, legal, and ethical specifics of these situations, but this knowledge is not integrated within emergency medical curricula at all. We present a case study to discuss such legal and ethical specifics.

Methods

We retrospectively analysed six emergency cases with palliative care patients in the final stages of their illnesses. On the basis of these case studies, we present six different emergency cases with different regulatory frameworks for each EP and paramedic. In accordance with the Declaration of Helsinki, data were collected pseudonymously.

Results

The six case studies show therapeutic concepts concerning the emergency medical care of palliative care patients during cardiac arrest. The differences are apparent in the treatment given by EPs and by paramedics (such as whether to start or stop resuscitation). EPs and paramedics differ in their therapeutic approach to these specific situations (e.g. paramedics more often start resuscitation during cardiac arrest even though patients would refuse this according to their advance directives). These differences may be important for the patient and his or her caregivers.

Conclusions

Every EP and paramedic may be involved in the care of palliative care patients who are at the end of their lives. EPs and paramedics do not always adapt their treatment to the will or supposed will of the patient (especially in accordance with the new German law concerning advance directives). The reasons for this usually concern legal uncertainties. Therefore, EPs and paramedics should know that different legal meanings could be important in emergency medical care therapy of palliative care patients. A written “do not resuscitate” order as an advance directive must be evaluated as a desired therapeutic limitation.     

"Highlights" in emergency medicine -- severe head trauma, polytrauma and cardiac arrest

According to scientific publications focusing on emergency medicine and published in international journals in the past few months, new and clinically important results can be identified. In patients with severe head trauma (SHT), application of hypertonic solutions is possible; long term outcome, however, is not improved by this measure. Prehospital capnometry is important, because otherwise up to 40 % of all mechanically ventilated patients are hypoventilated. In a study in 200 patients with prehospital cardiac arrest and ventricular fibrillation as initial cardiac rhythm, subgroup analysis (alarm-response time > 5 min) showed an increase in survival rate (14 % vs. 2 %), if defibrillation was proceeded by 3 min of conventional cardiopulmonary resuscitation (CPR) for reperfusion. If ACD ("active compression decompression")-CPR is combined with a specific ventilatory valve ("inspiratory impedance threshold device", ITD) which does not allow passive inspiration, survival rate after cardiac arrest is increased for up to 24 h. Such a device facilitates an increase in venous return to the heart during decompression of the thorax. High-dose adrenalin for intrahospital CPR in children is not associated with better survival but with worse outcome. Comparison of an emergency medical service (EMS) system from U.K. with paramedics and a physician-staffed German EMS system demonstrated that survival rate following prehospital cardiac arrest is markedly increased with doctors on board. The European multicentre trial comparing vasopressin vs. adrenalin as first vasopressor during CPR in 1219 patients did not reveal any differences between both groups. In subgroup analyses of patients with asystoly and prolonged CPR, vasopressin was superior without being associated with a benefit on neurological outcome. Further subgroup analyses revealed beneficial effects of amiodarone and thrombolysis during CPR. Thrombolysis during CPR apears to be associated with an increased rate of haemodynamic stabilisation without increased risk of bleeding complications. In a very clear advisory statement, the "International Liaison Committee on Resuscitation" (ILCOR) has recommended mild therapeutic hypothermia (i. e., cooling of cardiac arrest victims to 32 - 34 degrees C central body temperature for 12 - 24 h following cardiac arrest of cardiac etiology) not only for unconciuous patients with ventricular fibrillation as initial prehospital rhythm, but also for all other adult patients (other rhythms, intrahospital CPR) following cardiac arrest. In randomised controlled clinical trials, this therapy has markedly improved survival rate and neurological outcome. Such therapeutic cooling can be initiated nearly everywhere and with simple methods - like the infusion of ice-cold cristalloid solutions.     

Emergency medicine -- new concepts and therapies improve outcome from cardiac arrest

According to scientific articles focusing on emergency medicine published in international journals in the past few months, early defibrillation by lay persons, thrombolysis during cardiopulmonary resuscitation (CPR) and treatment with mild therapeutic hypothermia have been identified as relevant, new and clinically important treatment options to improve outcome following cardiac arrest. Early defibrillation using automated external defibrillators by lay persons reduces the time interval between collapse and first attempts at defibrillation and thus improves outcome after prehospital cardiac arrest. Thrombolysis during CPR -- for which the results regarding safety and efficacy are available from nonrandomized trials -- can also be safely performed in case of pulseless electrical activity. Thrombolysis during cardiopulmonary resuscitation has, however, no significant effect in this subgroup of patients with pulseless electrical activity in whom outcome is poor if the drug is administered at the end of conventional CPR procedures. Mild therapeutic hypothermia, i. e., cooling of cardiac arrest victims to 32-34 degrees C central body temperature for 12-24 h following out-of-hospital cardiac arrest, markedly improves survival rate and neurological outcome. Since this has now been clearly documented in two randomized clinical trials, it can be assumed that this kind of intervention will be recommended and translated into clinical practice soon. In conclusion, new and clinically relevant methods to improve outcome following cardiac arrest are available and can now be widely used clinically.     

Multicenter Canadian study of prehospital trauma care

OBJECTIVE: To evaluate whether the type of on-site care a trauma patient receives affects outcome. SUMMARY BACKGROUND DATA: The controversy regarding the prehospital care of trauma patients between Advanced Life Support (ALS) and Basic Life Support (BLS) is ongoing. Due to this unresolved controversy, as well as historical, cultural, and political factors, there are significant variations with respect to the type of prehospital care available for trauma patients. METHODS: This prospective cohort study compared three types of prehospital trauma care systems: Montreal, where physicians provide ALS (MD-ALS); Toronto, where paramedics provide ALS (PMD-ALS); and Quebec City, where emergency medical technicians provide BLS only (EMT-BLS). The study took advantage of this variation to evaluate the association between the type of on-site care and mortality in patients with major life-threatening injuries. All patients were treated at highly specialized tertiary (level I) trauma hospitals. The main outcome measure was death as a result of injury. Follow-up was to hospital discharge. RESULTS: The overall mortality rates by type of on-site personnel were physicians 35%, paramedics 24%, and EMTs 18%. For patients with major but survivable trauma, the overall mortality rates were physicians 32%, paramedics 28%, and EMTs 26%. The overall mortality rate of patients receiving only BLS at the scene was 18% compared to 29% for patients receiving ALS. For the subgroup of patients with major but survivable injuries, the mortality rates were 30% for ALS and 26% for BLS. The adjusted increased risk for mortality in patients receiving ALS at the scene was 21%. CONCLUSIONS: In urban centers with highly specialized level I trauma centers, there is no benefit in having on-site ALS for the prehospital management of trauma patients.     

Kindernotfälle im Notarztdienst Eine epidemiologische Studie am Notarztwagen Innsbruck

Objectives. We studied the epidemiology and outcome of prehospital pediatric emergencies treated by a physician-staffed mobile intensive care unit (MICU). Methods. A 3-year retrospective analysis for the period 1991–1993. Results. Children under the age of 15 years comprised 5.1% of the patients treated by the MICU (372/7423), 87.4% of whom were not in a life-threatening condition. The most common emergencies were: trauma (30.4%), febrile seizure (27.7%), and subglottal laryngitis (12.6%). In 44.6% of cases there was no medical indication for the MICU. Intubation at the scene was required by 17 patients (4.6%), and 11 (3.0%) underwent cardiopulmonary resuscitation following prehospital cardiac arrest; two children were successfully resuscitated but died in hospital. A total of 217 (61.3%) were admitted to the ward, 9 of these to a critical care unit. The average length of stay was 4.9 days, and 94.5% of patients were discharged in good health. Conclusion. Prehospital pediatric emergencies are rare and seldom life-threatening. Continuing education in pediatric emergency care is important for emergency physicians.     

Paediatric intubation in Scottish emergency departments

BACKGROUND: Intubation of children in the emergency department setting is uncommon. This prospective observational study examines the practice of paediatric intubation in Scottish adult/paediatric urban emergency departments. METHODS: A prospective observational study of every intubation attempt was performed in seven urban Scottish emergency departments in 1999 and 2000. Children were defined as those patients who were less than 13 years of age on the day of presentation. Prehospital intubations were only included if they were performed by a mobile medical team doctor from one of the seven hospitals. RESULTS: A total of 1713 patients were identified, 44 of whom (2.6%) were children. The median age was 4 years (range 0-12 years), and 57% (25 of 44) of intubations were performed on patients with traumatic injuries. Emergency physicians attempted intubation in 27% (12 of 44) of cases, anaesthetists in 73% (32 of 44); 18% (eight of 44) of patients were intubated in nontraumatic cardiac arrest, 68% (30 of 44) underwent rapid sequence intubation (RSI), one (2%) had inhalational anaesthesia and 13 (30%) were intubated without drugs. Eighty per cent (35 of 44) of patients were intubated at the first attempt; eight patients required two attempts, and one required three attempts. Three children were intubated prehospital by mobile medical teams. Emergency physicians intubated more patients with 'physiological compromise' (100% vs 91%). CONCLUSIONS: Paediatric intubation in the emergency department is uncommon. Collaboration and appropriate training for doctors in emergency medicine, anaesthesia and paediatrics is essential.     

Outcome after heroin overdose and cardiopulmonary resuscitation

Background:  The survival of heroin overdose patients resuscitated from cardiac arrest is reported to be poor. The aim of our study was to investigate the outcome and characteristics of survivors after cardiac arrest caused by heroin overdose.
Methods:  This was a retrospective study in a medium-sized city (population, 560,000). Between 1 January 1997 and 31 December 2000, there were 94 combined cardiac arrests caused by acute drug poisonings. The main outcome measure was survival to discharge.
Results:  Cardiopulmonary resuscitation was attempted in 19 heroin overdose patients (group A) and in 53 patients with cardiac arrest caused by other poisonings (group B). Three (16%) vs. six (11%) patients were discharged alive (group A vs. B, respectively). The survivors in group A had an Emergency Medical Service (EMS)-witnessed cardiac arrest or the Emergency Dispatching Centre was called before the arrest occurred. There was no statistically significant difference between the two groups in terms of survival. Survivors in both groups suffered from acute renal failure (two), hypoglycaemia (four) and hypothermia (three).
Conclusion:  Survival after cardiac arrest caused by heroin overdose is possible if the arrest is EMS witnessed or the Emergency Dispatching Centre is called before the cardiac arrest occurs. In comparison with cardiac arrests caused by other poisonings, there was no difference in survival. The incidence and mechanism of hypoglycaemia should be examined in further studies.     

Paramedic versus emergency physician emergency medical service: role of the anaesthesiologist and the European versus the Anglo-American concept

PURPOSE OF REVIEW: Much controversy exists about who can provide the best medical care for critically ill patients in the prehospital setting. The Anglo-American concept is on the whole to provide well trained paramedics to fulfil this task, whereas in some European countries emergency medical service physicians, particularly anaesthesiologists, are responsible for the safety of these patients. RECENT FINDINGS: Currently there are no convincing level I studies showing that an emergency physician-based emergency medical service leads to a decrease in overall mortality or morbidity of prehospital treated patients, but many methodical, legal and ethical issues make such studies difficult. Looking at specific aspects of prehospital care, differences in short-term survival and outcome have been reported when patients require cardiopulmonary resuscitation, advanced airway management or other invasive procedures, well directed fluid management and pharmacotherapy as well as fast diagnostic-based decisions. SUMMARY: Evidence suggests that some critically ill patients benefit from the care provided by an emergency physician-based emergency medical service, but further studies are needed to identify the characteristics and early recognition of these patients.     

Effektivität präklinischer Notfallversorgung Fiktion oder Fakt?

The current increase in the cost of health care must be considered as a severe threat to the prehospital emergency services system. Two examples have been selected – the patient with polytrauma and the patient in cardiac arrest – to demonstrate the dilemma between a need for objective data and the requirements of emergency patients. Study results obtained in trauma patients indicating that total prehospital time, including scene time, is correlated to patient outcome have led to the conclusion that at the scene treatment by emergency physicians may be dispensable. It has, however also been demonstrated that the time required for medical treatment at the scene is equivalent to 20% of the total scene time, thus representing only a fraction of the total prehospital time. Correlating the total prehospital time or scene time to outcome therefore appears absurd. The treatment principle of aggressive shock treatment in polytrauma needs critical reevaluation on the basis of results obtained by recent preclinical studies in patients with penetrating torso injuries. Small volume resuscitation could not be demonstrated to improve outcome in polytrauma patients, although a slight improvement in patients with brain injury may be assumed. Endotracheal intubation and early artificial ventilation are proven therapeutic principles in polytraumatized patients. Unfortunately, for ethical reasons randomised carefully controlled comparative studies can not be performed in polytrauma patients unless the patient is fully conscious. The importance of endotracheal intubation and artificial ventilation in unconscious trauma patients becomes apparent under conditions of anaesthesia where the application of the endotracheal tube averts regurgitation, aspiration and concomitant morbidity and mortality. The common causes of cardiovascular collapse and their pathomechanisms, as well as the mechanisms of cardiopulmonary resuscitation, have been widely investigated. Nevertheless, various aspects of their application are still controversial. The most recent study results have recommended initial ventilation prior to thoracic compression. New methods of assisting mechanical cardiopulmonary resuscitation, such as ACD CPR or vest CPR, have shown promising results in animal experiments. However, the importance of results obtained by preclinical randomised controlled investigations in humans need to be confirmed by further studies as to outcome. The efficacy of defibrillation in cases of ventricular fibrillation has been clearly demonstrated, particularly with a view to the interval between ventricular fibrillation and defibrillation. It has further been demonstrated that basic cardiopulmonary resuscitation preserves ventricular fibrillation and thus improves the chance of survival. The present generation of defibrillators has been further improved, particularly by the introduction of biphasic defibrillator wave forms, which may reduce the required energy, as well as possible complications, while offering an increase in the efficacy of defibrillation and a reduction in defibrillator size. Scientific emergency medicine is responsible not only for the development and validation of new methods and concepts, but in particular for their application under quality control conditions. Politicians require an improvement in the quality of the validation of emergency measures, although the instruments available for the investigation of these measures are known to be obsolete (experimental models, experimental design). Additionally, the financial support of research in emergency medicine suffers from being accourded low priority by public research funds such as the German Research Fund. However, in view of the rapid application of experimental results to daily practice it should be emphasized that patients also support research in emergency medicine via their direct financial contributions to the health insurance companies.     

Additional evidence in support of withholding or terminating cardiopulmonary resuscitation for trauma patients in the field

BACKGROUND: Survival for trauma patients who receive prehospital cardiopulmonary resuscitation (CPR) has been reported as poor. We assessed the survival for prehospital CPR in our trauma system and attempted to find prehospital predictors of mortality. STUDY DESIGN: We conducted a retrospective review of our Level I trauma center's database that identified 588 patients over a 6-year period (January 1, 1997, to December 31, 2002) who received prehospital CPR. Mechanisms of injury, prehospital vital signs, and survival to discharge were analyzed. RESULTS: Twenty-two of 588 patients (3.7%) survived to hospital discharge. Overall, 60.7% did not survive to achieve hospital admission, and an additional 32.6% died on the first hospital day. Patients with penetrating injuries had a significantly lower survival rate than those with either blunt or other (eg, drowning, hanging) injuries (0.9% versus 6.2%, and 13.2%, respectively, p < 0.001) and significantly lower Revised Trauma Scores (RTS; mean +/- SD: 0.32 +/- 0.96 versus 0.76 +/- 1.84 and 1.18 +/- 2.51, respectively, p < 0.05.) The likelihood of survival with RTS = 0 was less than 1% overall, and 0% for penetrating trauma. CONCLUSIONS: These findings add support to recent guidelines regarding the termination or withholding of resuscitation for trauma patients in the prehospital setting. Victims of penetrating trauma with a prehospital RTS = 0 (combination of no respiratory rate, no systolic blood pressure, and a Glasgow Coma Score of 3) should be declared "dead at the scene."     

Die präklinische Blutgasanalyse Teil 1: Der Stellenwert der präklinischen Blutgasanalyse

Prehospital blood gas analysis is a new method in out-of-hospital emergency care. In a prospective pilot study we evaluated the feasibility of prehospital compensation of severe acidosis relying on different monitoring systems to evaluate patients oxygen, carbon dioxide or acid-base status, respectively. Methods: With the help of arterial blood gas checks taken at the site of the emergency, the acid base status of patients undergoing out of hospital cardiopulmonary resuscitation was analysed. The values derived from the first arterial puncture were used to determine the presence and the type of acidosis. The data of the arterial blood gas checks were set into relation with the time elapsed since the beginning of resuscitation and they were compared with end-tidal CO₂. Results: During the observation period 26 blood gas analyses from patients who had out-of-hospital resuscitation because of cardiac arrest were done. Twenty three patients had severe acidosis (pH range <6.9 to 7.31), one had alkalosis (pH 7.51). Only two had an arterial pH within normal range. The pCO₂ was variable (range: 24 to 97 mm Hg). The correlation of pH with time from the beginning of resuscitation to arterial puncture was poor (r=0.407, p<0.05). There was no correlation between pH and BE (r=0.267) or pH and pCO₂, (r=0.016) respectively. Prehospital capnometry had a poor correlation with arterial pCO₂ in most emergeny patients. Only patients with respiratory disturbances of extrapulmonary origin showed a good correlation between end-tidal CO₂ and the arterial pCO₂. In severely ill patients the arterio-alveolar CO₂-difference was unexpectedly high (>15 mm Hg). In four patients resuscitation was not sucessful until compensation of an unexpectedly severe acidosis based upon the findings from blood-gas analysis had been performed. Conclusions: Arterial blood gas analysis proved to be helpful in the optimal management of out of hospital cardiac arrest. The incidence of severe acidosis in patients undergoing cardiopulmonary resuscitation was 80%. The probability of developing acidosis was found to increase slightly depending on the time elapsed since the beginning of CPR. The application of a calculated buffering of acidosis with sodium bicarbonate showed a good outcome in selected cases. In emergency patients alternative methods fail to detect severe disturbances of the patients oxygen and/or carbon dioxide status and the acid-base balance. Management of prehospital cardiac arrest could be optimized by the routine use of blood gas analysis.     

In-hospital cardiopulmonary resuscitation: organization, management and training in hospitals of different levels of care

BACKGROUND: : During recent years in-hospital cardiopulmonary resuscitation (CPR) management has received much attention. This can be attributed to the Utstein model for in-hospital CPR developed in 1997. The present status of in-hospital resuscitation management in Finnish hospitals is not known. Therefore, a study was designed to describe the organization of training and clinical management of CPR in Finnish hospitals of different levels of care. METHODS: : In the summer of 2000, we performed a cross-sectional mail survey throughout Finland, including all district, central and university hospitals. The questionnaire outlined in detail in-hospital resuscitation management and training. For analysis the hospitals were divided into primary, secondary and tertiary groups, depending on levels of care. RESULTS: : Most hospitals (72%) reported having a physician or a nurse in charge of resuscitation management and training. Training in advanced life support was more common among nurses (80%) than among physicians (53%). Surprisingly, a majority of respondents (75%) reported that they felt training in CPR was insufficient. On the general wards and on wards treating cardiac patients, defibrillation was in most cases performed by a physician (91% and 51%, respectively), and less often by a nurse (16% and 31%, respectively). In the secondary and tertiary hospitals cardiac arrest was managed by a cardiac arrest team (53% and 62%, respectively) and in the primary hospitals by the ward physician (56%), anesthesiologist or emergency physician on call (44%). Most hospitals used do-not-resuscitate orders (83%) but only 33% of the hospitals had a unified style of notation. Systematic data collection was practised in 55% of hospitals, predominantly by using a model of their own. Only a few hospitals (11%) used the in-hospital Utstein model. CONCLUSION: : Our study showed that more attention needs to be paid to CPR management in Finnish hospitals. At present, 25% of hospitals do not have an appointed physician or nurse in charge of organizing CPR management. The study also revealed a lack of regular organized training in resuscitation for physicians. Fifty-five per cent of hospitals practise systematic data collection, but only 11% according to the Utstein template; and without which further quality assurance is difficult.     

Potentially preventable trauma deaths: A retrospective review

BackgroundReviewing prehospital trauma deaths provides an opportunity to identify system improvements that may reduce trauma mortality. The objective of this study was to identify the number and rate of potentially preventable trauma deaths through expert panel reviews of prehospital and early in-hospital trauma deaths.MethodsWe conducted a retrospective review of prehospital and early in-hospital (<24 h) trauma deaths following a traumatic out-of-hospital cardiac arrest that were attended by Ambulance Victoria (AV) in the state of Victoria, Australia, between 2008 and 2014. Expert panels were used to review cases that had resuscitation attempted by paramedics and underwent a full autopsy. Patients with a mechanism of hanging, drowning or those with anatomical injuries deemed to be unsurvivable were excluded.ResultsOf the 1183 cases that underwent full autopsies, resuscitation was attempted by paramedics in 336 (28%) cases. Of these, 113 cases (34%) were deemed to have potentially survivable injuries and underwent expert panel review. There were 90 (80%) deaths that were not preventable, 19 (17%) potentially preventable deaths and 4 (3%) preventable deaths. Potentially preventable or preventable deaths represented 20% of those cases that underwent review and 7% of cases that had attempted resuscitation.ConclusionsThe number of potentially preventable or preventable trauma deaths in the pre-hospital and early in-hospital resuscitation phase was low. Specific circumstances were identified in which the trauma system could be further improved.     

Adrenaline administration during cardiopulmonary resuscitation: poor adherence to clinical guidelines

BACKGROUND: Adrenaline does not appear to improve the outcome after cardiac arrest in clinical trials in spite of beneficial effects in experimental studies. The objective of this study was to determine whether adrenaline was administered in accordance with advanced cardiac life support (ACLS) guidelines during adult cardiopulmonary resuscitation (CPR). METHODS: From 15 January to 31 December 2000, all patients at Uppsala University Hospital in whom CPR was attempted were registered prospectively. The duration of CPR was documented in the register and the total dose of adrenaline was retrieved retrospectively from patient records. From these data the average interval between adrenaline doses was calculated. RESULTS: Data for evaluation of the between-dose interval of adrenaline was available in 53 of 107 registered cardiac arrests. In 68% (36/53) the average between-dose interval was longer than the 3-5 min recommended in the guidelines, and 8% (4/53) received no adrenaline. The median interval between adrenaline doses during CPR was 6.5 min (25th-75th percentile: 5.1-10.4). Adherence to guidelines was lower in out-of-hospital cardiac arrest than in in-hospital cardiac arrest (P = 0.01). CONCLUSIONS: In the majority of cases adrenaline did not appear to be administered according to current ACLS guidelines.     

A critical analysis of outcome for children sustaining cardiac arrest after blunt trauma

Purpose: Injury is the leading cause of cardiac arrest in children older than 1 year. Previous findings suggest that children who require cardiopulmonary resuscitation (CPR) administered by paramedics for any reason rarely survive to hospital discharge. The authors evaluated the outcome of children sustaining cardiac arrest after blunt trauma in a Regional Pediatric Trauma Center. Methods: Children (age [lt ] 16) who underwent CPR in the field or in the emergency department (ED) after blunt trauma were identified from the trauma registry of a regional pediatric trauma center over a 3-year period (1997 to 2000). Patient demographics, rate of survival to discharge, factors influencing survival, and organ donation data were obtained from the trauma registry and medical record. Probability of survival (Ps) was calculated by TRISS analysis. Results: Twenty-five children were identified with a history of cardiac arrest after blunt injury (mean age; 3.3 years; range, 0.1 to 10; mean ISS, 30.7; range, 13-75; mean RTS, 1.58). Mean calculated Ps was 22.7%. However, only 2 (8%) survived. Death in the majority (91%) of the 23 patients who died occurred secondary to brain or spinal cord injury, and only 2 (9%) occurred as the result of exsanguinating hemorrhage. CPR was first performed in the field in 10 patients (40%), en route in 6 (24%), and in the ED in 9 (36%). Of the children who survived, both had vitals in the field, and CPR was administered initially in the ED. Mean length of ED resuscitation before death was 80 minutes. Of the children who died, organ donation occurred in only 3 (13%). The 2 survivors had no head injury and were discharged within 3 weeks of injury. Conclusions: Cardiopulmonary resuscitation after blunt injury in children rarely results in survival. The majority of deaths occur as a result of isolated intracranial injury and not exsanguinating hemorrhage. Although all children should receive aggressive resuscitation after injury, the need for CPR in the field portends a poor outcome. Furthermore, these data would suggest that prolonged or heroic efforts for children sustaining cardiac arrest in the field are not indicated.
