Transport beatmeter Notfallpatienten vom Hubschrauber zum Krankenhauszielort (HOVER-Studie)

Background

In Germany more than 110,000 helicopter emergency medical service (HEMS) missions are carried out annually. A considerable number of patients are ventilated during the flight. So far, structured surveys with respect to the ground transport from the helipad to the hospital facility and handover of ventilated patients in the emergency room (ER) are not available in the German-speaking HEMS system. The handover of ventilated HEMS patients in the ER (HOVER I study) explored the use of the helicopter ventilator and medical equipment during the transport from the hospital landing site to the ER.

Method

After approval by the HEMS operators, emergency medical doctors and HEMS technical crew members (HEMS-TC) of 145 German-speaking HEMS bases were invited to participate in an anonymous online survey (period: 1 February 2018–1 March 2018). Each participant was only allowed to submit the survey once.

Results

Data of 569 participants were completely analyzed, with responses from 429 emergency physicians and 140 HEMS-TC (75% from Germany, 13% Switzerland, 11% Austria, 1% Italy and Luxembourg). The most frequent type of aircraft used was the Eurocopter (EC)/Airbus helicopter (H) 135 (60.5%) followed by the EC/H 145 (33%). The majority of the respondents (53%) principally used the helicopter ventilator machine for patient transport from the helipad to the ER, 38% used it depending on the circumstances and 7% never used it. Of the participants 52% always took the emergency backpack for patient transport to the ER, 43% depending on the situation and 5% never took it along. The availability of oxygen or a ventilator at the helipad was considered to be helpful (59% and 45%, respectively), obligatory (25% and 14%, respectively) but was also considered unnecessary by some participants (16% and 40%, respectively). The collection of the HEMS team by a hospital team at the helipad was rated as helpful (64%) or mandatory (19%), 12% considered it to be unimportant and 5% even disturbing. For most respondents (58.5%) the responsibility for the patient ended after a structured handover on reaching the internal hospital target area (e.g. the ER).

Conclusion

The management of the handover of ventilated emergency patients in German-speaking HEMS is heterogeneously structured. Only approximately 50% of the participants frequently carried the helicopter ventilator and emergency equipment during patient transport to the ER. Depending on the situation, more than 90% of the respondents used the helicopter ventilator and emergency backpack during the transport. The collection of the HEMS team by a hospital team at the helipad was appreciated by the majority of participants. The use of the helicopter ventilator for patient transport to the ER needs to be explored in future studies.The study was registered at the Research Registry (www.researchregistry.com) under the following number: researchregistry2925

     

Die Rolle des Krankenhauses bei Bedrohungslagen

Hospitals play a major role in the population’s medical care, especially during terrorist attacks or other life-threatening mass casualty incidents. They are a key element in the evacuation of patients from an unsafe environment to a place of definitive medical treatment The basic principle of the medical emergency response to threatening situations of this kind is the rapid evacuation of the most seriously injured patients to the hospital emergency room. Therefore, hospitals need to deal with a large number of patients in a short period of time. In order to successfully manage such situations, hospitals need to be prepared and a comprehensive emergency plan is crucial tool. Effective measures include triage, the principals of tactical abbreviated surgery care, and a management strategy for personnel and material resources.     

Bewältigung von besonderen Bedrohungslagen

Background and methods

Terrorist attacks and rampages are extremely challenging situations for police and rescue forces. With the aim to define the lessons learned from the latest terrorist attacks in Germany and neighbouring European countries, the German Federal Office of Civil Protection and Disaster Assistance conducted a nationwide multilevel evaluation on behalf of the Federal Ministry of the Interior and the Federal Ministry of Health. In close collaboration with all organisations and institutions directly involved in the management of terrorist attacks or rampages, a number of conferences with thematic priorities were held in order to formulate conclusions and recommendations. The results of the conference ?prehospital casualty care“ are presented in this publication.

Results

Essential for the successful management of life-threatening mass casualty incidents is a well-trained concept for conventional mass casualty incidents. Specific conditions of rescue missions for terrorist attacks or rampages must be identified and the tactic consequences should complete the existing concepts. The specific conditions and the resulting consequences are described in the result section of this publication.

Conclusion

The presented lessons learned are the results of a nationwide evaluation process conducted by the Federal Office of Civil Protection and Disaster Assistance. It is seen as an expert opinion and might be of interest for all organizations and institutions dealing with the management of terrorist attacks or other life-threatening rescue missions.

Vest inflation without simultaneous ventilation during cardiac arrest in dogs: improved survival from prolonged cardiopulmonary resuscitation

Myocardial and cerebral blood flow can be generated during cardiac arrest by techniques that manipulate intrathoracic pressure. Augmentation of intrathoracic pressure by high-pressure ventilation simultaneous with compression of the chest in dogs has been shown to produce higher flows to the heart and brain, but has limited usefulness because of the requirement for endotracheal intubation and complex devices. A system was developed that can produce high intrathoracic pressure without simultaneous ventilation by use of a pneumatically cycled vest placed around the thorax (vest cardiopulmonary resuscitation [CPR]). The system was first tested in a short-term study of the maximum achievable flows during arrest. Peak vest pressures up to 380 mm Hg were used on eight 21 to 30 kg dogs after induction of ventricular fibrillation and administration of epinephrine. Microsphere-determined myocardial blood flow was 108 +/- 17 ml/min/100 g (100 +/- 16% of prearrest flow) and cerebral flow was 51 +/- 12 ml/min/100 g (165 +/- 39% of prearrest). Severe lung or liver trauma was noted in three of eight dogs. If peak vest pressure was limited to 280 mm Hg, however, severe trauma was no longer observed. A study of the hemodynamics during and survival from prolonged resuscitation was then performed on three groups of seven dogs. Vest CPR was compared with manual CPR with either conventional (300 newtons) or high (430 newtons) sternal force. After induction of ventricular fibrillation, each technique was performed for 26 min. Defibrillation was then performed.(ABSTRACT TRUNCATED AT 250 WORDS)     

An investigation into the effects of real vs. stimulated cases and level of experience on the distribution of visual attention during induction of general anaesthesia

In anaesthesia, patient simulators have been used for training and research. However, insights from simulator‐based research may only translate to real settings if the simulation elicits the same behaviour as the real setting. To this end, we investigated the effects of the case (simulated case vs. real case) and experience level (junior vs. senior) on the distribution of visual attention during the induction of general anaesthesia. We recorded eye‐tracking data from 12 junior and 12 senior anaesthetists inducing general anaesthesia in a simulation room and in an actual operating room (48 recordings). Using a classification system from the literature, we assigned each fixation to one of 24 areas of interest and classified the areas of interest into groups related to monitoring, manual, and other tasks. Anaesthetists gave more visual attention to monitoring related areas of interest in simulated cases than in real cases (p = 0.001). We observed no effect of the factor case for manual tasks. For other tasks, anaesthetists gave more visual attention to areas of interest related to other tasks in real cases than in simulated cases (p < 0.001). Experience level did not have an effect on the distribution of visual attention. The results showed that there were differences in the distribution of visual attention by between real and simulated cases. Therefore, researchers need to be careful when translating simulation‐based research on topics involving visual attention to the clinical environment.     

Whole-body multislice computed tomography as the primary and sole diagnostic tool in patients with blunt trauma: searching for its appropriate indication

In our hospital, whole-body multislice computed tomography is used as the primary diagnostic tool in patients with suspected multiple trauma. A triage rule is used for its indication. We have retrospectively analyzed data of sedated, intubated and ventilated patients consecutively admitted to our trauma center to assess whether the triage rule can help identify patients with severe trauma (injury severity score ≥16). We have found that overtriage (injury severity score <16) occurs in 30%, and undertriage occurs in 6% of patients. Although we have found the triage rule to be highly sensitive, this results in a high rate of overtriage. Until we know more about the most relevant and independent predictive factors, sole reliance upon multislice computed tomography in triaging suspected polytrauma victims will imply the risk to overscan many patients.
