Epidemiology of hand traumas during the COVID-19 confinement period

Introductionhand injuries are a common emergency mainly caused by domestic accidents or sport injuries. During the COVID-19 pandemic confinement period, with a cut off in transportation as well as in occupational and physical activities, we observed a decrease in medical and elective surgical activities but emergency cases of upper limb and hand surgery increased.Materials and methodswe conducted a retrospective epidemiological study to analyze two periods between the same dates in 2019 and 2020, for all the duration of the confinement period. We compared the numbers of consultations in the emergency department, elective surgeries, hand and upper limb emergency cases in our center and urgent limb surgeries in the nearby hospital. Then we compared the mechanisms and severity of injuries and the type of surgery.Resultsbetween 2019 and 2020 there was a decrease of consultations in the emergency department in our institution of 52%, a decrease of total elective surgeries of 75%, a decrease in surgeries for urgent peripheral limb injuries of 50%, whereas the hand and upper limb emergency remained stable or even increased by 4% regard to occupational and domestic accidents.There was a significant difference in the mechanism of injury with an increase of domestic accident and a decrease of occupational, road traffic and sport accidents. Severity of the injuries increased, with augmentation of the number of tissues involved and longer expected time of recovery.Conclusionduring the confinement period of the COVID-19 pandemic, despite an important reduction of medical activities, the amount and severity of hand emergency cases increased. A specific plan regarding duty shift organization for hand trauma should be maintained regardless of the sanitary situation.     

Emergency free flaps to the type IIIC tibial fracture

Type IIIC tibial fractures are complex injuries involving extensive bone and soft-tissue devascularization that result in a high percentage of complications and ultimate amputation. An emergency free flap transfer not only may salvage the limb but also may improve the aesthetic and functional results of reconstruction by placing the injured structures in a well-vascularized bed. Two cases of type IIIC tibial fracture were treated in this manner, and we present our experience with a 30-month follow-up of one patient and a 6-month follow-up of another patient.     

Weißbuch Schwerverletztenversorgung der DGU

The white paper published by the German Society for Trauma Surgery in 2006 on the treatment of serious injuries calls for the nationwide establishment of regional trauma networks and the certification of national and regional trauma centres, as well as centres for the basic care of seriously injured persons. The hospitals involved are to be provided with precise requirements regarding qualifications of the round-the-clock personnel, the management, as well as regarding equipment. A national trauma centre must commit itself to taking in seriously injured patients at any time, as well as being able to treat two seriously injured patients simultaneously. Also, the management level of basic care centres should comprise a specialist physician with additional qualifications in trauma surgery, and the centre should provide a 24-h emergency service for the emergency treatment of seriously injured patients. Appropriate treatment of the 8.5 million accidents occurring annually in Germany and causing injuries which require treatment is an important issue from an economic point of view. Of the total cost of treating a seriously injured person of 500,000 EUR, the rescue and hospital costs total only 6.9%, but are relevant for the follow-up costs. Thus, any investments in this regard also make economic sense.     

Implementation of a trauma team

A team approach to the initial assessment, investigation and management of potentially seriously injured patients has been instituted. Team members are alerted through an emergency paging system which is activated when a patient fulfills one of a predetermined list of criteria relating to the injury incident, physiological status of the patients and anatomic injuries. Medical members of the team include surgical, intensive care, anaesthetic, and accident and emergency staff. The surgical representative acts as team co-ordinator. Aspects of the function of the trauma team system were assessed over 4 months during which time 721 injured patients were admitted, 240 patients satisfied the trauma team criteria, and the team was called 152 times. The observed 'false alarm' rate was 38% but the true false alarm rate would have been 46%. Injuries sustained by some patients, who satisfied the criteria but who were not evaluated by the team, were of sufficient severity to justify a greater compliance with the system than was observed at this early stage after its implementation. Although a false alarm rate of 46% is higher than desirable, the number of calls per day would still only average 2 in a hospital with a high trauma patient load. The checklist criteria were highly sensitive (97%) in identifying those patients who should have been evaluated by the trauma team. Although hospitals differ in workload and staffing, this trauma team model is recommended for more widespread use and for further evaluation and modification.     

Thoracic trauma in the pre-hospital phase

Preclinically relevant injuries of the thorax are described patho-physiologically. The diagnosis at the scene of accident and the treatment of the emergency of the functional after-effect injury are described. Respiratory insufficiency requires early artificial respiration. A pneumothorax should be drained, at least, on the respired patient. If there is a pneumothorax associated with tension due to the confined air, the relief would be obligatory. The relief should take place after the digital opening of the thorax by silicon drainage. If there is a mediastinal emphysema with a seriously haemodynamic effect, the relief would be indicated by collar mediastinostomy. If there is a pericardium tamponade with circulatory collapse after a perforating trauma, the patient must be brought to the medical attention of a surgeon as quickly as possible. The delay in time must not be the consequence of the relief of puncture. If a person injured in an accident who has a rupture of the trachea can not be respired immediate exposure of the rupture site is imperative. Resuscitation measures in case of an injured thorax must be done at the opened thorax.     

The hospital trauma team: a model for trauma management

A triage system was established as the initiating mechanism for a trauma team response to assist the assessment and early management of patients presenting to an accident and emergency department. A checklist of triage criteria was used. During a 6-month period, 342 patients (29.7% of trauma admissions) satisfied the triage criteria, which should have resulted in an average of 1.9 trauma team calls per day. Staff compliance with the triage tool was 75.4%. The overtriage rate for the checklist criteria was 52.7%. The triage tool identified patients with severe injuries who were not initially considered sufficiently injured to justify initiation of the trauma team response. The sensitivity of the triage tool in identifying patients with serious injury was 95.0%. Comparison of the review with a similar review performed 12 months earlier demonstrated that staff compliance with initiating the trauma team response had improved. Using data from 564 patients from both series, logistic regression analysis of the power of the triage criteria to predict serious injury contributed to a revision of the triage criteria. This trauma triage tool and trauma team response constitute a valid approach to the early hospital management of trauma patients. This system may be more appropriate or achievable in many hospitals than the construction of dedicated trauma reception units or permanent surgical staffing of general Accident and Emergency departments.     

Abschätzung von Operationskapazitäten bei einem Massenanfall von Verletzten anhand des Zeitbedarfs für lebensrettende Notfalloperationen

The surgical treatment capacity of a hospital constitutes a significant restriction in the capability to deal with critically injured patients from multiple or mass casualty incidents (MCI). With regard to the time needed for life-saving operative interventions there are no basic reference values available in the literature, which can aid in detailed planning for management of mass casualty incidents. The data of 20,815 trauma patients, recorded in the trauma registry hosted by the German Association for Trauma Surgery DGU, were analyzed to extract the median duration of life-saving surgical interventions carried out in an operating theatre. Inclusion criteria were an ISS > or = 16 and the performance of relevant ICPM coded procedures within 6 h after trauma room admission. Orthopedic procedures as well as the placement of ICP catheters and chest tubes or performance of laparoscopies were not included. Complete data sets with the required variables were available from 9,988 trauma patients with an ISS > or = 16, and included 7,907 interventions that took place within 6 h after hospital admission. From among 1,228 patients 1,793 operations could be identified as relevant life-saving emergency operations. Acute injury to the abdomen was the major cause accounting for 54.1% of all emergency surgical procedures with a median intervention duration of 137 min followed by head injuries accounting for 26.3% with a median duration of 110 min. Interventions in the pelvis amounted to 11.5% taking an average of 136 min, 5.0% were in the thorax requiring 91 min and 3.1% major amputations with 142 min. The average cut to suture time for all emergency surgical interventions was 130 min. A prerequisite for estimating the surgical operation capacity for critically injured patients of an MCI is the number of OR teams available during and outside of the normal working hours of the hospital. The average operation time of 130 min calculated from investigation of 1,793 emergency life-saving surgical procedures provides a realistic guideline. Used in combination with the number of available OR teams the prospective treatment capacity can be estimated and projected into an actual incident admission capacity. The identification and numerical value of such significant variables are the basis for operations research and realistic planning in emergency and disaster medicine.     

Penetrating injuries to the subclavian and axillary vessels

BACKGROUND: Subclavian and axillary vascular injuries are notorious for their mortality and their difficult surgical exposure. In the present study we analyze our experience with 79 patients and describe the techniques used for surgical access to these vessels. STUDY DESIGN: Retrospective review of the medical records of all patients with penetrating injuries to the subclavian or axillary vessels who had been admitted to 2 Los Angeles trauma centers during a 4-year, 3-month period. RESULTS: Seventy-nine patients were admitted during the study period January 1993 to March 1997 (58 gunshot injuries, 21 other penetrating injuries). The artery was injured in 59 patients and the vein in 40 (20 patients had both arterial and venous injuries). Eighteen patients (23%) were admitted with no signs of life or were in extremis and underwent an emergency room thoracotomy without any survivors. Fifty-eight patients underwent exploration in the operating room, 1 patient with an arteriovenous subclavian fistula was successfully managed with a radiologically placed endovascular stent, and 2 patients with minimal subclavian artery injuries were managed nonoperatively. Overall mortality was 34.2%. Excluding the ER thoracotomies the overall mortality was 14.8%. The mortality for isolated arterial injuries was 20.5%, for isolated venous injuries 50%, and for both vessels 45.0%. The mortality in venous injuries was significantly higher than in arterial injuries (p < 0.05). The standard clavicular incision provided adequate exposure in 32 (50.0%) of the operating room cases. In the other 50% of operating room cases a combination of a clavicular incision with a median sternotomy or thoracotomy was necessary. Proximal subclavian injuries may be accessed through a clavicular incision combined with a median sternotomy irrespective of left or right site location. CONCLUSIONS: Subclavian and axillary vascular injuries remain lethal. A clavicular incision provides satisfactory surgical exposure in about half the patients. In patients with proximal injuries addition of a median sternotomy provides adequate surgical access in both right and left subclavian vessels.     

Revised trauma score: a triage tool in the accident and emergency department

We evaluated the Revised Trauma Score (RTS) for the rapid identification of severely injured patients on their arrival at the accident and emergency department. A total of 1407 consecutively injured patients admitted to the Accident and Emergency Department of the Royal Victoria Hospital, Belfast, had their RTSs calculated on arrival. A trauma team, consisting of experienced senior doctors, was summoned for all patients with an abnormal RTS of 11 or less. Each patient also had their Injury Severity Score (ISS) calculated later, and this was compared with their RTS on admission. It was found that 53 patients had an ISS of 16 or above, indicating severe injury. The RTS identified 42 of these. Of the remaining 11, five had incurred penetrating trauma and three spinal cord injuries. Clinical examination revealed actual or potentially serious injuries in all eight patients. However, serious injuries were not recognized initially in three patients due to physiological compensation and/or a short time lapse between injury and arrival at hospital. On admission 49 patients had an abnormal RTS, but their final ISS was less than 16. Forty had injuries warranting urgent resuscitation or a period of observation. Of the remaining nine patients, five had fractures with an elevated respiratory rate, presumably due to pain, and the other four had a depressed level of consciousness which could be accounted for by alcohol intoxication alone. Our results reinforce some well-known points. First, alcohol alone should not be assumed to be the only cause for a depressed level of consciousness in patients with head injuries. Second, systolic hypotension following trauma is an important sign of serious injury. We recommend the use of the RTS as an aid to junior doctors in the recognition of seriously injured patients in the accident and emergency department. Furthermore, the score should be recalculated at frequent intervals while the patient remains in the department.     

Isolated Pancreatic Transection Due to Blunt Abdominal Trauma: Report of Three Cases and Literature Review

Abstract Pancreatic injuries caused by blunt abdominal trauma are rare occurrences consisting a small percentage of all pancreas injuries. Due to difficulties in diagnosis evaluation and associated injuries, blunt pancreas traumas are severe clinical cases with high mortality rates. We would like to discuss three cases admitted to our hospital last year, and current literature on diagnosis, management and surgical approach of blunt pancreas injuries. The incidents resulted from a traffic accident, a parade horse stamping the groom and a football game, in which the latter patient unfortunately died. These cases illustrate the importance of careful diagnosis, interpretation of findings and therapy planning of the acutely injured patient suffering blunt pancreatic trauma.     

Notfallversorgung bei Verkehrsunfällen in einem Flächenstaat

A change is emerging in the hospital landscape due to health political measures, which in consequence also influences the prehospital medical care in emergencies. The main focus of this study was to gather information about emergency medical care after traffic accidents on the basis of data from Bavarian emergency medical services. In 2006 there were 14,261 traffic accidents in Bavaria where an emergency doctor attended the scene. The patients were primarily cared for by land-based rescue services and air rescue services were only used in 19.1% of the cases. Of the patients involved in a traffic accident 47.6% were transported to a primary health care hospital. A prehospital interval of more than 60 min occurred in 20% of the missions. Of the patients 96.2% were transported to tertiary or maximum care hospital by air rescue services but emergency facilities were, however restricted to daylight hours. There was a further limitation due to the routine duty hours in hospitals as only 36.7% of accidents occurred during this time intervall. An increase of admission post trauma in maximum care clinics occurred from 2002 until 2006 while simultaneously the prehospital period was extended. In order to assure sufficient trauma care for seriously injured persons a continuous 24 h availability of emergency trauma facilities is necessary. For this purpose it is necessary to establish regional trauma networks between receiving hospitals as well as air rescue services at night time. Furthermore, a cost-efficient compensation of the structural, personnel and logistic expenses for the treatment of the severely injured has to be assured.     

Médicalisation préhospitalière héliportée et agressions cérébrales secondaires d'origine systémique chez les traumatisés craniocérébraux graves

Advanced supportive therapy at the site of the accident, associated with direct transfer to a trauma centre increases survival and reduces morbidity rates. Patients with severe head injury, especially those with multiple injuries, often arrive in the emergency department with potentially causes of serious secondary systemic insults to the already injured brain, such as acute anemia (Hematocrit ≤ 30 %), hypotension (systolic arterial pressure (Pa_sys) ≤ 95 mmHg, 12,7 kPa), hypercapnia (PaCO₂ ≥ 45 mmHg, 6 kPa) and/or hypoxemia (Pao₂ ≤ 65 mmHg, 8,7 kPa). The incidence of such insults and their impact on mortality were studied in a group of 51 consecutive adults suffering from non penetrating severe head injury (Glasgow score ≤ 8, mean age 31 ± 17 yrs) rescued by a medicalised helicopter. Each patient received medical care on the site of the accident by an anaesthesiologist of a university hospital (UH) complying with an advanced trauma life support protocol including intubation, hyperventilation with FIO₂ = 1, restoration of an adequate Pa_sys and direct transportation to the UH. Mean delay from call to arrival of the rescue team on the site was 15 ± 5 min. Mean scene time was 32 ± 10 min in cases not requiring extrication. Nineteen patients (Group I) were admitted without secondary systemic insults to the brain, 13 with isolated head injury, and 6 with multiple injuries, with a low Glasgow Outcome Score (GOS 1–3) of 42 % at 3 months. In 32 patients (Group II), despite advanced supportive measures at the scene of the accident and during transportation, one or more secondary systemic insults to the brain were detected upon arrival at the emergency room, one with isolated head injury, 31 with multiple injuries, with a bad GOS of 72 % at 3 months. We conclude that : 1) advanced trauma life support prevents from secondary systemic insults in the great majority of isolated severe head injured patients, 2) secondary systemic insults to the already injured brain are frequent in patients with multiple injuries and are difficult to avoid despite rapid aeromedical trauma care, 3) secondary systemic insults to the brain have a catastrophic impact on the outcome of severely head injured patients.     

Changes in emergency surgery between 1973 and 1982: audit of the workload of one surgical team

The emergency surgical workload of a consultant in general surgery has been studied by comparing two prospectively collected audits of 6-month periods 9 years apart. There have been a number of changes in the pattern and intensity of general surgical admissions (excluding trauma) with a decline in the total number per day from 14.1 to 12.4 and a reduction in the number of days on call for general surgery from 30 to 14 over the 6-month period. There was a similar fall in days on call for trauma from 60 to 23 days and a decline in total emergency surgical operations from 6.6 to 5.2 operations per night on call. These changes have mainly been produced by an increase in the number of consultants in the hospital from five to eight and specialisation with the establishment of an area urology unit. The results of this study suggest that as consultant numbers increase in a particular area there will be diminished exposure of surgical trainees to emergency cases both in quantity and in quality, and this loss of experience will prove deleterious to the trainee surgeon.     

Integrating emergency general surgery with a trauma service: impact on the care of injured patients

BACKGROUND: There has been considerable discussion on the national level on the future of trauma surgery as a specialty. One of the leading directions for the field is the integration of emergency general surgery as a wider and more attractive scope of practice. However, there is currently no information on how the addition of an emergency general surgery practice will affect the care of injured patients. We hypothesized that the care of trauma patients would be negatively affected by adding emergency general surgery responsibilities to a trauma service. METHODS: Our institution underwent a system change in August 2001, where an emergency general surgery (ES) practice was added to an established trauma service. The ES practice included emergency department and in-house consultations for all urgent surgical problems except thoracic and vascular diseases. There were no trauma staff changes during the study period. Trauma registry data (demographics, injuries, injury severity, and procedures) and performance improvement data (peer-review judgments for all identified errors, denied days, audit filters, and deaths) were abstracted for two 15-month periods surrounding this system change. Chi-square, Fisher's exact, and t tests provided between-group comparisons. RESULTS: The trauma staff evaluated a total of 5,874 patients during the 30-month study. There were 1,400 (51%) trauma admissions in the pre-ES group and 1,504 (48%) in the post-ES group, of which 1,278 and 1,434, respectively, met severity criteria for report to our statewide database (Pennsylvania Trauma Outcome Study [PTOS]). There were 163 (12.7% of PTOS) deaths in the pre-ES group compared with 171 (11.9% PTOS) deaths in the post-ES group (p = not significant [NS]). There was one death determined to be preventable by the peer review process for the pre-ES group, and none in the post-ES group. Both groups had 10 potentially preventable deaths, with the remaining mortalities being categorized as nonpreventable (p = NS). Unexpected deaths by TRISS methodology were 36 (2.8%) and 41 (2.9%) for the two groups, respectively (p = NS). There was no difference in the number of provider-specific complications between the groups (23, [1.8%] vs. 19 [1.3%], p = NS). The addition of emergency surgery has resulted in an additional average daily workload of 1.3 cases and 1.2 admissions. CONCLUSION: Despite an increase in trauma volume over the study period, the addition of emergency surgery to a trauma service did not affect the care of injured patients. The concept of adding emergency surgery responsibilities to trauma surgeons appears to be a valid way to increase operative experience without compromising care of the injured patient.     

Can adult trauma surgeons care for injured children?

Large urban trauma centers care for injured children as well as adults in many areas of the country, but the quality of care in these hospitals has not been evaluated versus that available at pediatric trauma centers. The recent validation of TRISS methodology in pediatric populations allowed us to evaluate the quality of pediatric trauma care being provided in a level I trauma center treating injured patients of all ages. We reviewed the records of 353 injured children (aged 0-17 years) who were admitted to our trauma center over a 30-month period for the following data: demographics, mechanism of injury, initial physiologic status (RTS), surgical procedures required, need for intensive care, nature and severity of the injuries (ISS), and outcome. TRISS analysis allowed us to compare our population with the Major Trauma Outcome Study. Only two of the 21 total deaths (overall mortality, 6%) were unexpected, and there were seven unexpected survivors. One hundred twenty-one patients underwent emergency surgical procedures and 63 required admission to the intensive care unit. The Z scores ranged from +0.32 for the children aged less than 2 years to +3.98 for the older age group (14-17 years). We conclude that the quality of care for pediatric trauma patients admitted to trauma centers that care for patients of all ages compares favorably with national standards. In most areas of the country, improvements in pediatric trauma care will likely come from addressing the special needs of injured children in general trauma centers rather than from developing separate pediatric facilities.     

An experience with upper-extremity vascular trauma

In this 6-year study of 101 limbs requiring surgical intervention for upper-extremity vascular trauma, most patients were male, young, and injured by penetrating objects. Injured vessels included 13 axillary/subclavian, 23 brachial, 40 radial, and 25 ulnar arteries. Concomitant injuries included nerve injury in 50 cases, tendon laceration in 29, and bony fracture in 11. Arterial repair was accomplished by primary repair in 54 limbs, vein graft in 26 limbs, and vein patch in 3 limbs. Seventeen arterial injuries were ligated. Ancillary procedures included 30 nerve or 27 tendon repairs. The limb salvage rate was 99%. No functional deficits were noted in those cases with only a vascular injury. In 64% and 25% of patients with nerve or musculoskeletal injury, respectively, the arm was functionally impaired. Prompt diagnosis and surgical intervention eliminate vascular injury as a factor in upper-extremity limb loss or disability. Functional deficits are the result of nerve or orthopedic injuries.     

Vascular injuries of the limbs: a fifteen-year Georgian experience.

OBJECTIVES: to analyse the causes of injury, surgical approaches, outcome and complication of vascular trauma of the upper and lower limbs in patients with vascular injuries operated on over a period between 1981 and 1995. PATIENTS: in 157 patients, the injuries were penetrating in 136 cases and blunt in 21. Isolated vascular trauma was present in 92 (58.6%) patients, 65 cases (41.4%) were aggrevated by concomitant bone fractures, severe nerve and soft tissue damage. The most frequently injured vessels were the superficial femoral (20. 6%) and brachial (19.1%) arteries. RESULTS: saphenous vein interposition grafting was applied with good results in 34 patients, polytetrafluoroethylene grafts were used in three cases, end-to-end anastomoses in 42 cases, venous bypasses in five cases, and venous patches in seven cases. Seventeen patients underwent arterial repair and nine, venous repair. Fasciotomy was used in 18 cases, and vessels were ligated in 14 cases. Blood flow was restored in 91 patients (58.0%), and collaterals compensated in 31 cases (19.7%). Fourteen primary and nine secondary amputations were performed. Twelve patients died. The limb salvage rate was 77.7% (84.1% among surviving patients). CONCLUSIONS: most vascular injuries associated with limb trauma can be managed successfully unless associated by severe concomitant damage to bones, nerves and soft tissues.

Arithmetik der Traumaversorgung

Interventions in the sense of a surgical session according to SGB V are determined for the most part from the number of general anaesthetics induced for the department. The capacity of an operating theatre can be calculated from experience at 4–6 operations per day, that is to say 1,000 operations per year if 200 full operating days per year are assumed. If we assume that 80% of patients in the trauma surgery department do undergo operative treatment, that the average time each patient is then occupying a bed is 7 days, and that the rate of bed use is 85%, this means that for every 1,000 surgical operations an average of 28.3 beds must be reserved – as a rule of thumb, between 20 and 30 beds for each operating theatre. In Germany, 1000 surgical patients in a trauma surgery department means 200 injured as defined by GUV; on average the injuries are serious in 25% of these cases. Speed in trauma surgery is defined in increments of 1,000 operations performed per year. Thus, double speed means 2,000 operative cases per year, two operating theatres in constant use and the treatment of 500 seriously injured patients needing trauma surgery. The rough figures mentioned can be used as a quantifiable basis for estimation of the performance structure of trauma surgery departments in Germany.     

Surgical trainees and trauma emergencies

An accident and emergency (A&E) training has been suggested as an essential part of the basic surgical training. The A&E curriculum should be divided into three sections: a critical curriculum, a core curriculum and a comprehensive curriculum. For instance, the critical curriculum contains topics that provide the opportunity to translate the ABCDE principles of trauma management into practice. Furthermore, a post in the A&E department provides the surgical trainee with significant exposure to the management of the polytrauma patient and to the management of other acute general surgical, urological and orthopaedic conditions. By presenting better educational programs and by reducing the non-medical tasks a trainee has to deal with, the education of surgical trainees during A&E attachment can be improved.
