Thoracotomy in the emergency department for resuscitation of the mortally injured.

PURPOSE: Emergency department resuscitative thoracotomy is an intervention of last resort for the acutely dying victim of trauma. In light of improvements in pre-hospital emergency systems, improved operative strategies for survival such as damage control and improvements in critical care medicine, the most extreme of resuscitation efforts should be re-evaluated for the potential survivor, with success properly defined as the return of vital signs which allow transport of the patient to the operating room. METHODS: A retrospective review of all patients at a suburban level I trauma center who underwent emergency department resuscitative thoracotomy as an adjunct to the resuscitation efforts normally delivered in the trauma receiving area over a 22 year period was performed. Survival of emergency department resuscitative thoracotomy was defined as restoration of vital signs and transport out of the trauma resuscitation area to the operating room. RESULTS: Sixty-eight patients were identified, of whom 27 survived the emergency department resuscitative thoracotomy and were transported to the operating room. Review of pre-hospital and initial hospital data between these potential long term survivors and those who died in the emergency department failed to demonstrate trends which were predictive of survival of emergency department resuscitative thoracotomy. The only subgroup which failed to respond to emergency department resuscitative thoracotomy was patients without signs of life at the scene who arrived to the treatment facility without signs of life. CONCLUSION: The patient population of the "potential survivor" has been expanded due to advances in critical care practices, technology, and surgical technique and every opportunity for survival should be provided at the outset. Emergency department resuscitative thoracotomy is warranted for any patient with thoracic or subdiaphragmatic trauma who presents in extremis with a history of signs of life at the scene or organized cardiac activity upon arrival. Patients who have no evidence of signs of life at the scene and have no organized cardiac activity upon arrival should be pronounced.

An update on the surgeons scope and depth of practice to all hazards emergency response.

This article outlines the position of The Eastern Association of the Surgery of Trauma (EAST) in defining the role of surgeons, and specifically trauma/critical care surgeons, in the development of public health initiatives that are designed to react to and deal effectively with acts of terrorism. All aspects of the surgeon's role in response to mass casualty incidents are considered, from prehospital response teams to the postevent debriefing. The role of the surgeon in response to mass casualty incidents (MCIs) is substantial in response to threats and injury from natural, unintentional, and intentional disasters. The surgeon must take an active role in pre-event community preparation in training, planning, and executing the response to MCI. The marriage of initiatives among Departments of Public Health, the Department of Homeland Security, and existing trauma systems will provide a template for successful responses to terrorist acts.

Clearing the cervical spine in victims of blunt trauma.

Cervical spine injuries occur in 2.3% to 6.4% of victims of blunt trauma. The difficulty of identifying the minority of patients with cervical spine injuries continues to challenge those who triage and treat the acutely injured. We retrospectively reviewed our practice for cervical spine clearance, which consists of three-view plain radiographs supplemented by focused further studies, such as computed or plain film tomography and flexion/extension views, as needed. Fifty-four patients with cervical spine injuries were identified during a 39-month period, which represented approximately 1% of the patients evaluated. Eighty cervical spine injuries were found, of which nine were missed. Review of the six patients in whom the nine cervical spine injuries were missed demonstrated error in the interpretation of radiographic studies in five patients, only two of whom were felt to have technically adequate films in hindsight. We conclude that a protocol based on three-view plain film radiographs supplemented by focused additional studies will allow the visualization of virtually all cervical spine injuries and that the main cause of missed injuries is errors of interpretation.

Preoperative radiographic staging for ureteral injuries is not warranted in patients undergoing celiotomy for trauma.

Preoperative radiographic staging of the urinary tract has been shown to be inaccurate with regard to the ureter. The purpose of this study was to assess the need for radiographic staging of the injured patient for the diagnosis of ureteral injury before operative exploration. We conducted a retrospective review of all patients who sustained injury of the ureter as the result of external trauma over an 8 Y2-year period at an urban and suburban Level I trauma center. All patients were injured through penetrating mechanisms and underwent laparotomy. Only three patients had preoperative radiographic staging of the urinary tract. No ureteral injuries were missed. We conclude that surgical exploration of the ureter is sufficiently accurate to obviate the need for preoperative radiographic staging of the ureters in patients who have sustained penetrating injury and warrant laparotomy.

The role of nephrectomy in the acutely injured.

HYPOTHESIS: The high mortality in patients who undergo nephrectomy after trauma is not secondary to the nephrectomy itself but is the consequence of a more severe constellation of injuries associated with renal injuries that require operative intervention. DESIGN: A retrospective review of all patients identified using International Classification of Diseases, Ninth Revision codes as having sustained renal injuries over a 62-month period. PATIENTS: Seventy-eight patients with renal injuries who underwent exploratory laparotomy were identified. METHODS: All medical records were reviewed for patient management, definitive care, and outcome. Based on outcome, patients were assigned to either the survivor or nonsurvivor group. For patients who underwent nephrectomy, intraoperative core temperature changes, estimated blood loss, and operative time were also reviewed. RESULTS: Seventy-eight patients with renal injuries who underwent exploratory laparotomy were identified. Twenty-nine patients underwent laparotomy with conservative management of the renal injury, of whom 5 (17.2%) died. Twelve patients had renal injuries repaired and all survived. Thirty-seven patients underwent nephrectomy, of whom 16 (43.2%) died. Compared with nephrectomy survivors, nephrectomy nonsurvivors had a significantly lower initial systolic blood pressure, higher Injury Severity Score, higher incidence of extra-abdominal injuries, shorter operative duration, and higher estimated operative blood loss. The nephrectomy survivors' core temperature increased a mean of 0.5 degrees C in the operating room, while the nephrectomy nonsurvivors' core temperature cooled a mean of 0.8 degrees C. CONCLUSIONS: Patients who undergo trauma nephrectomy tend to be severely injured and hemodynamically unstable and warrant nephrectomy as part of the damage control paradigm. That a high percentage of patients die after nephrectomy for trauma demonstrates the severity of the overall constellation of injury and is not a consequence of the nephrectomy itself.

Recidivism in equestrian trauma.

A 3-year chart survey and questionnaire was conducted of equestrian-injured patients at a regional trauma center to determine patterns and consequences of injury and rate of recidivism. Ninety-two patients (95 encounters) were treated; most were young (mean age, 27 +/- 11 years) women (84%) riders sustaining falls (80%). Most injuries were orthopedic (47%); 19 per cent of patients required hospital admission. There was one death. Helmet use was documented in only 34 per cent. Eighty-one per cent of patients responded to a follow-up telephone survey; 36 per cent recounted additional accidents (mean, 1.4 +/- 0.5). Mean time lost from work was 3 weeks, with 19 per cent reporting chronic disability. Mean annual hospital charges for the cohort were $88,925.00. Recidivism is common in equestrian trauma. Hospital charges are significant. Lost time from work is considerable, with one in five patients reporting long-term disability. Given the cost and disability incurred with equestrian trauma, efforts at injury prevention appear warranted.

The importance of the command-physician in trauma resuscitation.

OBJECTIVE: Definitive trauma team leadership, although difficult to measure, has been shown to improve trauma resuscitation performance. The purpose of this study was to evaluate the effect of an identified command-physician on resuscitation performance. In addition, the leadership capability of four physician combinations functioning as command-physician was studied. DESIGN: Retrospective review. METHODS: Videotapes of trauma resuscitations performed at a Level I trauma center over a 25-month period were reviewed. The presence of an identified command-physician was determined by multidisciplinary consensus. Resuscitation performance was measured by compliance with three objective criteria: primary survey, secondary survey, and definitive plan; and two subjective criteria: orderliness, and adherence to Advanced Trauma Life Support protocol. Performance was then analyzed (1) as a function of the presence or absence of a command-physician, and (2) between four identified physician combinations: AF (attending surgeon + trauma fellow); F (trauma fellow); ASR (attending surgeon + senior surgical resident); SR (senior surgical resident). Chi square and the Mann-Whitney U tests were applied. RESULTS: A total of 425 trauma resuscitations were reviewed. A command-physician was identified (CP[Pos]) in 365 resuscitations (85.7%); no command-physician was identified (CP[NEG]) in 60 (14.3%). Compliance with completion of secondary survey (81.4%) and formulation of a definitive plan (89.6%) was significantly higher in the CP(POS) group. Subjective scores for orderliness and adherence to Advanced Trauma Life Support protocol were significantly higher in the CP(POS) group. In the CP(POS) resuscitations, formulation of a definitive plan was lower in SR when compared with the other three physician combinations. CONCLUSIONS: An identified command-physician enhances trauma resuscitation performance. Completion of the primary and secondary survey is not affected by the physician combination. Prompt formulation of a definitive plan is facilitated by the active involvement of an attending traumatologist or a properly mentored trauma fellow.

Barrier precautions in trauma resuscitation: real-time analysis utilizing videotape review.

Blood-borne pathogens threaten all individuals involved in emergency health care. Despite recommendations by the Centers for Disease Control and the American College of Emergency Physicians, documented compliance with universal precautions in trauma resuscitation has been poor. The purpose of this study was to determine the factors that predispose to noncompliance with barrier precautions at a level I trauma center. Videotapes of trauma resuscitations performed during 1 month (n = 66) were reviewed. Full compliance with barrier precautions was documented in 89.1% of health care workers. Of the noncompliant health care workers, 50.7% were emergency department personnel and 47.8% were first responders to the trauma resuscitation area. Barrier precaution compliance improved from 62.5% to 91.8% with prenotification of patient arrival. Immediate access to barrier equipment is essential for all potential in-hospital first responders. Prehospital communication systems should be optimized to ensure prenotification.
