Shooting up? Analysis of 182 gunshot injuries presenting to a London major trauma centre over a seven-year period.

Introduction Metropolitan Police data, and those from the emergency department at a London major trauma centre show a resurgence in gun crime. The aim of this study was to collect data on all gunshot injuries over a seven-year period at South-East London's trauma hub. Materials and methods This was a retrospective observational study of all gunshot injuries between 1 January 2010 and 31 December 2016 at a London major trauma centre. Information regarding patient demographics, morbidity and mortality was collected. Data from the English indices of multiple deprivation were reviewed in relation to shooting locations and socioeconomic status in South-East London. Results A total of 182 patients from 939,331 emergency admissions presented with firearm injuries. Males comprised 178 (97.8%) victims and 124 (68.1%) were documented as being Black or Afro-Caribbean. The median age was 22 years. Some 124 (71.7%) victims were shot within a 4 km radius of the hospital. The mean indices of multiple deprivation decile ranking in shooting locations compared with non-shooting locations was 2.6 (± 0.1384) and 3.8 (± 0.1149), respectively. A total of 122 (67.0%) patients underwent specialist operative intervention and 111 (61.0%) suffered only superficial or musculoskeletal injuries. Six patients required emergency thoracotomies; three (50.0%) survived to discharge. The median length of stay was 4 days (interquartile range 2-9 days) and 35 (24.0%) were admitted to intensive care. Ten (5.5%) patients died. Discussion and conclusion Firearms injuries are increasing and place a significant burden on hospital resources. Care provided to gunshot victims has improved as a result of recent trauma management initiatives at South-East London's major trauma centre.

Epidemiology of penetrating injuries in the United Kingdom: A systematic review.

INTRODUCTION: Penetrating injuries account for a significant number of deaths in the United Kingdom (UK) annually. Numerous articles have examined the epidemiology of penetrating trauma in various areas of the UK. This article aimed to systematically review the current literature and evaluate the incidence and mortality of penetrating injury according to region in the UK. METHODS: A systematic literature search was performed using MEDLINE® (1946 to June 2016), EMBASE® (1974 to June 2016), and PsycINFO® (1806 to June 2016) databases. The following keywords were used in combination with Boolean operators: "epidemiology", "incidence", "frequency", "pattern", "distribution"; "penetrating"; "injuries", "injury", "trauma"; "United Kingdom", "UK", "England", "Scotland", "Wales", "London". RESULTS: Eleven relevant studies were identified across five regions of the UK. Study periods ranged from 3 months to 16 years and encompassed between 343 and 127,191 patients. Relative incidence within individual studies ranged from 0.3% (Midlands) to 21.0% (London) and mortality ranged from 0.5% (London) to 15.4% (Midlands). The majority of patients were young males. DISCUSSION: An extensive range of incidence and mortality rates were observed between studies in all regions. This was largely dependent on the study population under review. London was found to have the highest incidence of penetrating injuries, however these studies tended to focus on populations of trauma patients. The high proportion of male victims may reflect the risk of becoming involved in gangs and violence. CONCLUSIONS: Our ambiguous results indicate the need for further work directed towards the epidemiology of penetrating injuries within regional trauma networks.

An urban trauma centre experience with abdominal vena cava injuries.

BACKGROUND: The aim of the study was to present the surgical management of injuries to the abdominal vena cava (AVC) and to identify clinical and physiological factors and management strategies which affect the outcome. METHOD: A retrospective review was conducted of AVC injuries in patients attending the trauma centre at Groote Schuur Hospital, Cape Town, from January 2003 to December 2011. Demographic data, mechanism and agent of injury, level of injury, physiological parameters, associated injuries, trauma scores, management strategy, morbidity and mortality, and length of hospital stay were taken from the trauma centre's operative databank at Groote Schuur Hospital. RESULTS: Thirty-fi ve patients with AVC injuries were identifi ed. There were 33 penetrating injuries (94%). Gunshot wounds accounted for 28 of them (85%). There were 19 (54%) infrarenal, 9 (26%) juxtarenal, 3 (7%) suprarenal and 4 (11%) retrohepatic AVC injuries. Most patients were treated with ligation (66%). There were 17 (49%) deaths. There were signifi cant differences in the preoperative systolic blood pressure (p = 0.044), number of red cell units transfused (p = 0.001), serum lactate (p = 0.007), arterial pH (p = 0.002) and preoperative temperature (p = 0.000) between the survivors and non-survivors. There was also a signifi cant difference in ligation versus repair between the two groups (p = ≤ 0.000). There was no difference in the injury severity, level of injury and the number of associated injuries between survivors and non-survivors. CONCLUSION: AVC injuries are associated with high mortality. Patients presenting with clinical and physiological evidence of shock and who require "damage control" surgery are more likely to suffer a worse outcome, particularly when multiple physiological deragements are present. Patients who died often have severe associated injuries.

Mechanisms of injury and CT findings in bowel and mesenteric trauma.

Bowel and mesenteric injuries are relatively uncommon but associated with significant morbidity and mortality. Early recognition is crucial, and multidetector computed tomography (MDCT) now has a central role in the evaluation of patients with a history of trauma. In this review, we describe the MDCT appearances of bowel and mesenteric injuries with reference to findings at surgery. Emphasis is placed on the importance of an understanding of mechanism of injury when interpreting CT findings following abdominal trauma.
