Are prehospital deaths from trauma and accidental injury preventable? A direct historical comparison to assess what has changed in two decades.

BACKGROUND & OBJECTIVES: In 1994, Hussain and Redmond revealed that up to 39% of prehospital deaths from accidental injury might have been preventable had basic first aid care been given. Since then there have been significant advances in trauma systems and care. The exclusion of prehospital deaths from the analysis of trauma registries, giv en the high rate of those, is a major limitation in prehospital research on preventable death. We have repeated the 1994 study to identify any changes over the years and potential developments to improve patient outcomes. METHODS: We examined the full Coroner's inquest files for prehospital deaths from trauma and accidental injury over a three-year period in Cheshire. Injuries were scored using the Abbreviated-Injury-Scale (AIS-1990) and Injury Severity Score (ISS), and probability of survival estimated using Bull's probits to match the original protocol. RESULTS: One hundred and thirty-four deaths met our inclusion criteria; 79% were male, average age at death was 53.6 years. Sixty-two were found dead (FD), fifty-eight died at scene (DAS) and fourteen were dead on arrival at hospital (DOA). The predominant mechanism of injury was fall (39%). The median ISS was 29 with 58 deaths (43%) having probability of survival of >50%. Post-mortem evidence of head injury was present in 102 (76%) deaths. A bystander was on scene or present immediately after injury in 45% of cases and prior to the Emergency Medical Services (EMS) in 96%. In 93% of cases a bystander made the call for assistance, in those DAS or DOA, bystander intervention of any kind was 43%. CONCLUSIONS: The number of potentially preventable prehospital deaths remains high and unchanged. First aid intervention of any kind is infrequent. There is a potentially missed window of opportunity for bystander intervention prior to the arrival of the ambulance service, with simple first-aid manoeuvres to open the airway, preventing hypoxic brain injury and cardiac arrest.

Prehospital deaths from trauma: Are injuries survivable and do bystanders help?

BACKGROUND AND OBJECTIVES: Deaths from trauma occurring in the prehospital phase of care are typically excluded from analysis in trauma registries. A direct historical comparison with Hussain and Redmond's study on preventable prehospital trauma deaths has shown that, two decades on, the number of potentially preventable deaths remains high. Using updated methodology, we aimed to determine the current nature, injury severity and survivability of traumatic prehospital deaths and to ascertain the presence of bystanders and their role following the point of injury including the frequency of first-aid delivery. METHODS: We examined the Coroners' inquest files for deaths from trauma, occurring in the prehospital phase, over a three-year period in the Cheshire and Manchester (City), subsequently referred to as Manchester, Coronial jurisdictions. Injuries were scored using the Abbreviated-Injury-Scale (AIS-2008), Injury Severity Score (ISS) calculated and probability of survival estimated using the Trauma Audit and Research Network's outcome prediction model. RESULTS: One hundred and seventy-eight deaths were included in the study (one hundred and thirty-four Cheshire, forty-four Manchester). The World Health Organisation's recommendations consider those with a probability of survival between 25-50% as potentially preventable and those above 50% as preventable. The median ISS was 29 (Cheshire) and 27.5 (Manchester) with sixty-two (46%) and twenty-six (59%) respectively having a probability of survival in the potentially preventable and preventable ranges. Bystander presence during or immediately after the point of injury was 45% (Cheshire) and 39% (Manchester). Bystander intervention of any kind was 25% and 30% respectively. Excluding those found dead and those with a probability of survival less than 25%, bystanders were present immediately after the point of injury or "within minutes" in thirty-three of thirty-five (94%) Cheshire and ten of twelve (83%) Manchester. First aid of any form was attempted in fourteen of thirty-five (40%) and nine of twelve (75%) respectively. CONCLUSIONS: A high number of prehospital deaths from trauma occur with injuries that are potentially survivable, yet first aid intervention is infrequent. Following injury there is a potential window of opportunity for the provision of bystander assistance, particularly in the context of head injury, for simple first-aid manoeuvres to save lives.

Management of blunt liver trauma in children.

INTRODUCTION: Management of liver trauma in childhood represents a rare but formidable challenge. METHODS: Clinical presentation, grade of liver injury and Injury Severity Score (ISS) were studied in 11 cases of blunt liver trauma to examine factors influencing outcome. RESULTS: Seven of the 11 children were injured severely and had an ISS greater than 16. Seven who were haemodynamically stable were treated without operation, but four required surgery for grade III, IV and V liver injuries. Two children had primary repair of hepatic lacerations. Perihepatic packing was employed in two other cases (grade IV and V injury) for uncontrollable haemorrhage. Delayed debridement and thrombectomy plus vena cava repair with suturing of liver lacerations in these patients obviated heroic efforts at primary repair. Nine children survived. There were two deaths from head and neck trauma. DISCUSSION: Selected children with liver trauma can be managed non-operatively using established trauma guidelines. Perihepatic packing is recommended in unstable patients with complex injuries, followed by delayed definitive repair.

Complications of percutaneous endoscopic enterostomy tubes.

Percutaneous endoscopic gastrostomy and jejunostomy tubes have been used clinically for approximately 10 years. They have been used predominantly in patients who cannot sustain their weight by oral intake, such as individuals with abnormalities of swallowing or intestinal peristalsis. The percutaneous endoscopic method of placement confers some advantages over classical surgical placement, especially in poor risk cases. Although several types of tube are commercially available, a substantial complication rate is still directly attributable to the tubes. In some series, complications are reported in 70% of cases. This report describes two complications of endoscopically introduced jejunostomy tubes used in patients with Roux-en-Y reconstructions after previous multiple gastric surgical procedures.
