Reduction in critical mortality in urban mass casualty incidents: analysis of triage, surge, and resource use after the London bombings on July 7, 2005.

BACKGROUND: The terrorist bombings in London on July 7, 2005, produced the largest mass casualty event in the UK since World War 2. The aim of this study was to analyse the prehospital and in-hospital response to the incident and identify system processes that optimise resource use and reduce critical mortality. METHODS: This study was a retrospective analysis of the London-wide prehospital response and the in-hospital response of one academic trauma centre. Data for injuries, outcome, triage, patient flow, and resource use were obtained by the review of emergency services and hospital records. FINDINGS: There were 775 casualties and 56 deaths, 53 at scene. 55 patients were triaged to priority dispatch and 20 patients were critically injured. Critical mortality was low at 15% and not due to poor availability of resources. Over-triage rates were reduced where advanced prehospital teams did initial scene triage. The Royal London Hospital received 194 casualties, 27 arrived as seriously injured. Maximum surge rate was 18 seriously injured patients per hour and resuscitation room capacity was reached within 15 min. 17 patients needed surgery and 264 units of blood products were used in the first 15 h, close to the hospital's routine daily blood use. INTERPRETATION: Critical mortality was reduced by rapid advanced major incident management and seems unrelated to over-triage. Hospital surge capacity can be maintained by repeated effective triage and implementing a hospital-wide damage control philosophy, keeping investigations to a minimum, and transferring patients rapidly to definitive care.

Helical computed tomographic scanning for the evaluation of the cervical spine in the unconscious, intubated trauma patient.

BACKGROUND: Assessment of the spine in the unconscious trauma patient is limited by an inadequate clinical examination. The potential of a missed unstable disc or ligamentous injury results in many patients remaining immobilized in critical care units for prolonged periods. METHODS: This study evaluates helical computed tomographic (CT) scanning of the whole cervical spine as part of a spinal assessment and clearance protocol. RESULTS: Four hundred thirty-seven unconscious, intubated, blunt trauma patients underwent CT scanning of the cervical spine. Sixty-one patients had a cervical spine injury and 31 (7.0%) were unstable. CT scanning had a sensitivity of 98.1%, a specificity of 98.8%, and a negative predictive value of 99.7%. There were no missed unstable injuries. In contrast, an adequate lateral cervical spine film detected only 24 injuries (14 unstable), with a sensitivity of 53.3%. CONCLUSION: Helical CT scanning of the cervical spine allows rapid and safe evaluation of the cervical spine in the unconscious, intubated trauma patient.

Pancreatic and duodenal injuries: keep it simple.

BACKGROUND: The management of pancreatic and duodenal trauma has moved away from complex reconstructive procedures to simpler methods in keeping with the trend towards organ-specific, damage control surgery. METHOD: A retrospective case note review was undertaken over a 30-month period to evaluate a simplified protocol for the management of these injuries. RESULTS: Of 100 consecutive patients there were 51 with pancreatic injury, 30 with a duodenal injury and 19 with combined pancreaticoduodenal trauma. Overall mortality was 18.0%, with a late mortality (after 24 h) of 9.9%. This is comparable to previous studies. Morbidity from abscesses, fistulas and anastomotic breakdown was acceptably low. CONCLUSION: The concept of staged laparotomy can be successfully applied to wounds of the pancreas and duodenum. Debridement of devitalized tissue and drainage can be employed for most cases of pancreatic trauma. Most duodenal injuries can be managed with debridement and primary repair. Temporary exclusion and reoperation should be employed for unstable patients.

Acute traumatic coagulopathy.

BACKGROUND: Traumatic coagulopathy is thought to be caused primarily by fluid administration and hypothermia. METHODS: A retrospective study was performed to determine whether coagulopathy resulting from the injury itself is a clinically important entity in severely injured patients. RESULTS: One thousand eight hundred sixty-seven consecutive trauma patients were reviewed, of whom 1,088 had full data sets. Median Injury Severity Score was 20, and 57.7% had an Injury Severity Score > 15; 24.4% of patients had a significant coagulopathy. Patients with an acute coagulopathy had significantly higher mortality (46.0% vs. 10.9%; chi2, p < 0.001). The incidence of coagulopathy increased with severity of injury, but was not related to the volume of intravenous fluid administered (r2 = 0.25, p < 0.001). CONCLUSION: There is a common and clinically important acute traumatic coagulopathy that is not related to fluid administration. This is a marker of injury severity and is related to mortality. A coagulation screen is an important early test in severely injured patients.
