A Population-Based Study of Pancreatic Trauma in Scotland

Introduction The aim of this population-based study was to assess the incidence, mechanisms, management and outcome of patients who sustained pancreatic trauma in Scotland over the period 1992–2002. Methods The Scottish Trauma Audit Group database was searched for details of any patient with pancreatic trauma. Results About 111 of 52,676 patients (0.21%) were identified as having sustained pancreatic trauma. The male-to-female ratio was 3:1, with a median age of 32 years. Blunt trauma accounted for 66% of injuries. Road traffic accidents were the most common mechanism of injury (44%), followed by assaults (35%). Thirty-four patients (31%) were haemodynamically unstable on arrival at hospital. Pancreatic trauma was associated with injuries to the chest (56%), head (30%) and extremities (30%); 73% of patients had other intra-abdominal injuries. Of those who left the emergency department alive, at least 77% required a laparotomy. The mortality rate (46%) was directly proportional to the number of injuries sustained (P < 0.05) and was higher in patients with increasing age (P < 0.05), haemodynamic instability (P < 0.05) and blunt trauma (P < 0.05). Conclusions Pancreatic trauma is rare in Scotland but is associated with significant mortality. Outcome was worse in patients with advanced age, haemodynamic instability, blunt trauma and multiple injuries. All work done in Edinburgh, Scotland, UK.     

Esophagogastric Trauma in Scotland

Background

This study was designed to investigate the incidence of esophageal (ET) and gastric trauma (GT) in Scotland and to identify factors associated with adverse outcome.

Methods

Population-based study of a prospective multicenter database of 52,887 trauma patients, admitted to 25 hospitals from 1992 to 2002.

Results

Thirty patients [0.06?%; median age, 32?year (range, 15–79); 86.7?% male] sustained ET [17 (56.7?%) blunt vs. 13 (43.3?%) penetrating]. The most common causes of injury were road traffic accidents (RTAs; n?=?11; 36.7?%) and assaults (n?=?10; 33.3?%). Most patients (n?=?25; 83.3?%) had injury severity scores (ISS) >15, consistent with severe trauma. Fifteen patients (50?%) underwent surgery, of whom 8 (53.3?%) died. Another 13 patients died, yielding an overall mortality rate of 70?%. In contrast, 149 patients [0.29?%; median age, 28?year (range, 13–74); 90.6?% male] sustained GT [124 (83.2?%) penetrating vs. 25 (16.8?%) blunt]. The predominant cause was assault (n?=?119; 79.9?%). Most patients (n?=?134; 89.9?%) underwent surgery, of which 23 (17.2?%) died. Another 12 patients died, yielding an overall mortality rate of 23.5?%. Factors associated independently with GT mortality included higher ISS, lower Glasgow coma scale (GCS), and hemodynamic compromise.

Conclusions

Esophagogastric trauma occurs predominantly in young males. The incidence of GT, although low, is five times that of ET. Predominant mechanisms of GT are penetrating compared with blunt for ET. Both ET and GT are commonly found in the presence of other multiple injuries, and are associated with high mortality. Operative management of GT is associated with reduced mortality, but outcome is worse for patients with hemodynamic compromise, low GCS, and high ISS.     

Non-operative management of solid organ injuries in a middle-income country,how does it stack up?

IntroductionThe first trauma surgery unit in Malaysia was established in 2011. After 10 years, we examine our experience in the management, and outcomes of blunt liver, spleen, and kidney injuries.MethodsThis is a cross-sectional study of patients with blunt liver, spleen, and kidney injuries in a level 1 trauma centre in Malaysia between January 2018 to June 2021. Patients’ characteristics, new injury severity score, organ-specific AAST injury score, type of primary management (operative management [OM], non-operative management [NOM]), causes of failed NOM, management of failed NOM, and outcome of treatment were recorded and analysed.ResultsAmong 448 patients, 83.9% were male and in the working-age range of 15–64 years old (93.5%). Road traffic crashes made up 92.0% of blunt trauma resulting in 65.5% of isolated organ injuries and 34.5% combined injuries. An overwhelming 84.2% of the patients had major trauma (NISS>15). Three hundred and thirty-four patients (74.6%) underwent initial non-operative management. Patients in the OM group showed lower mean GCS scores (p = 0.022) and higher NISS scores (p < 0.001). High-grade liver and kidney injuries were mostly treated with NOM (p < 0.001). In contradistinction, patients with high-grade spleen injuries had more OM performed (p < 0.001). NOM had been successful in 325 patients (97.3%) with 9 failures. Underlying causes for NOM failure were hemodynamic instability due to secondary bleeding and infectious complications. Overall mortality was 11.2%, which was significantly higher in the OM group (23.7%) than in the NOM group (6.9%).ConclusionThis study represents one of the largest single centre experiences on the blunt liver, spleen, and kidney injuries in Malaysia and South-East Asia. With good selection and adequate resources, non-operative management of blunt liver, spleen, and kidney injuries is a safe and effective therapeutic approach with a high success rate of 97.3%, avoiding the morbidity of unnecessary laparotomies.     

Traumatic injury to the colon and rectum in Scotland: demographics and outcome

Aim An analysis of a multi‐centred database of trauma patients was performed. Method The study used data from a prospective multi‐centre trauma database containing details of 52 887 trauma patients admitted to participating Scottish Hospitals over an 11‐year period. Results Three hundred and forty (0.64%) of 52 887 trauma patients (284 male) with colorectal injuries were identified; 43.9% of colorectal injuries occurred following blunt trauma and 56.1% following penetrating injury. Patients in the latter group were younger, had less haemodynamic compromise and were less likely to die than those with blunt trauma (P < 0.01). The overall mortality rate was 25.6% and after rectal injury it was 21.2% (P > 0.05). Female gender, increased age, road traffic accidents and those admitted as a result of a blunt traumatic injury were associated with increased mortality. Age > 65 years (P = 0.01), increasing injury severity score (ISS) at presentation (P < 0.001), haemodynamic compromise (P = 0.045) and decreased Glasgow Coma Score (GCS) (P < 0.001) had the strongest independent associations with mortality. Conclusion Colorectal injury after trauma has a high morbidity. Clinical features associated with death allow stratification of mortality risk.     

Outcome and management of blunt liver injuries in multiple trauma patients

Background: In Germany, abdominal trauma in multiple- trauma patients can be observed in about 25–35% of all cases. Due to major bleeding complications, the initial treatment of blunt abdominal trauma in multiple-trauma patients has high priority. The aim of this study was to discuss management, treatment and outcome of blunt liver injury in multiple-trauma patients treated in our department. Methods: The clinical records of 1192 multiple-trauma patients [injury severity score (ISS) 3–18] treated at the Surgical Department of the University Clinic of Essen from January 1975 to February 1998 were reviewed. Seventy-five patients with an ISS above 18 operated on due to a blunt liver injury could be included. The mean age was 29.82±1.80 years (60 males and 15 females). The degree of injury in this group was high (ISS 37.12±1.06). Results: Twenty-three of the 75 (30.6%) patients died during their hospital stay. Deceased patients were older (27±2 years versus 37±4 years; P<0.01) and had a higher ISS (ISS=34.5±1 versus 43.2±2; P<0.01). In nine cases, death was strongly related to liver injury. Operational blood loss was higher in the group of multiply injured patients with liver injury and in those patients who did not survive (P<0.05). An increased mortality could be seen in this selected patient group when compared with our large collective of multiply injured patients. The age of the patients, the ISS and operative blood loss were the significant factors that influenced the operative mortality after blunt hepatic injuries in our study.

Early results of low-velocity ballistic femoral shaft fractures

IntroductionBallistic femur fractures are a common injury treated at United States civilian trauma centers. This study investigates the outcomes of these injuries by comparing the rates of infection, nonunion, secondary operations, and associated injuries from low-velocity gunshot (GSW) injuries with fractures sustained by blunt trauma.MethodsA retrospective cohort comparative study was performed at a Level 1 trauma center. 345 patients with closed blunt or GSW femoral shaft fractures over 10 years were included. All were treated with intramedullary nail fixation. Superficial and deep infection, vascular injury, compartment syndrome, nonunion, and secondary operations were identified.Results148 patients in the GSW group and 197 patients in the blunt trauma group had overall mean age 33.5 years and 80% were male. Deep infection rates were similar There were no nonunions in the GSW group, contrasted with 8 (4.4%) nonunions in the blunt trauma group (p = 0.02). The rate of compartment syndrome was higher in the GSW group (6.1% vs 0, p < 0.001). Arterial injury occurred in 9% following GSW (vs 0, p < 0.001). Overall, secondary unplanned procedure rates were the same: 8.1% for both groups.DiscussionBallistic femoral shaft fractures are often equated with open injuries; however, rates of infection and secondary operations closely mirror that of closed injuries resulting from blunt force trauma. Nonunions may be more common after blunt injury, and compartment syndrome and arterial injury are substantially more common following GSW, warranting careful clinical assessment.Level of evidencePrognostic, level III.     

Hepatic venous injury after blunt abdominal trauma

Data on 306 liver injuries were collected prospectively during a 10-year period. Of the 306 injuries, 281 were the result of blunt trauma. Major hepatic venous injuries were encountered in 41 of 306 patients (13%). Blunt trauma was responsible for 39 of the 41 venous injuries. Twenty-five (61%) of these patients died compared with an overall mortality rate of 31% (chi 2; p less than 0.001). Twenty-two of the 25 deaths were caused by blood loss. Two patterns of hepatic venous injury appeared to predominate: avulsion of the trunk of the right hepatic vein from the inferior vena cava and avulsion of the upper branch of the right hepatic vein. The trunk injury was seen in 15 patients, 12 of whom died. The branch injury was seen in 13 patients, only 4 of whom died (Fisher's exact test; p = 0.006). In what appears to be the largest series of blunt hepatic venous injuries published, the injuries have been classified according to the anatomic site of the injury. Such a classification correlates with prognosis. Differences between blunt and penetrating hepatic venous trauma have been discussed.     

Injuries associated with pediatric liver trauma

Injury remains the leading cause of childhood mortality for children younger than 14 years of age, with the liver being particularly susceptible to blunt trauma in children. This study reviews the authors' institutions' experience with pediatric liver injuries in an attempt to establish current patterns of injury, management and outcomes. A single-center, retrospective review was conducted of 105 consecutive pediatric patients who presented with a traumatic liver injury from January 1996 through February 2004. Average patient age was 13.1+/-4.9 years and 58 per cent were male. Perihospital mortality was 8.6 per cent, with 67 per cent of mortality being attributed to head injury. The majority of patients were managed nonoperatively (81%). Liver injury was most often grade II (35%) by CT scan. Liver injury grade did not affect survival, but did affect injury management, with grade I and grade IV liver injuries more likely to be managed surgically (P < 0.001). Grade I liver injuries were associated with concomitant spleen injuries, whereas grade IV injuries were associated with pancreatic injuries. Surgical management was associated with a higher injury severity score (P = 0.005), higher mortality (P = 0.01), and with other associated injuries as well. Children experiencing blunt abdominal trauma are at risk of significant morbidity and mortality; however, these risks stem more likely from associated injuries than injury to the liver proper. Clinicians should maintain a high index of suspicion for potentially catastrophic associated injuries to the pancreas with high-grade liver injury.     

Acute Ethanol Intoxication and the Trauma Patient: Hemodynamic Pitfalls

Many trauma patients are acutely intoxicated with alcohol. Animal studies have demonstrated that acute alcohol intoxication inhibits the normal release of epinephrine, norepinephrine, and vasopressin in response to acute hemorrhage. Ethanol also increases nitric oxide release and inhibits antidiuretic hormone secretion. This article studies the effects of alcohol intoxication (measured by blood alcohol level, BAL) on the presentation and resuscitation of trauma patients with blunt hepatic injuries. A retrospective registry and chart review was conducted of all patients who presented with blunt liver injuries at an ACS-verified, level I trauma center. Data collected included admission BAL, systolic blood pressure, hematocrit, International Normalized Ratio (INR), liver injury grade, Injury Severity Score (ISS), intravenous fluid and blood product requirements, base deficit, and mortality. From September 2002 to May 2008, 723 patients were admitted with blunt hepatic injuries. Admission BAL was obtained in 569 patients, with 149 having levels >0.08%. Intoxicated patients were more likely to be hypotensive on admission (p = 0.01) despite a lower liver injury grade and no significant difference in ISS. There was no significant difference in the percent of intoxicated patients requiring blood transfusion. However, when blood was given, intoxicated patients required significantly more units of packed red blood cells (PRBC) than their nonintoxicated counterparts (p = 0.01). Intoxicated patients also required more intravenous fluid during their resuscitation (p = 0.002). Alcohol intoxication may impair the ability of blunt trauma patients to compensate for acute blood loss, making them more likely to be hypotensive on admission and increasing their PRBC and intravenous fluid requirements. All trauma patients should have BAL drawn upon admission and their resuscitation should be performed with an understanding of the physiologic alterations associated with acute alcohol intoxication.     

Splenic Trauma in Scotland: Demographics and Outcomes

Background Splenic trauma is a common organ injury following blunt abdominal trauma. In order to establish the contemporary epidemiology of blunt splenic trauma in Scotland and to detect risk factors associated with patient outcomes, analysis of a multi-center database of trauma patients was performed. Methods The study used data from a prospectively collated multicenter trauma database containing the details of 52,215 trauma patients admitted to participating Scottish hospitals over an 11-year period. Results 672 (1.3%) patients (530 males, 142 females) with splenic trauma were identified; of them, 579 (86.2%) had blunt trauma and 93 (13.8%) had penetrating trauma. The mean age of patients with blunt splenic trauma was 35.7 years (33.8 years for males, 42.0 years for females). Increasing age and female sex was significantly associated with mortality. The most common mechanism for injury was road traffic accidents (71%). In the series, 93.8% of patients had concomitant injuries including head injuries (46.5%), thoracic injuries (37.7%) and liver injuries (30%). A total of 299 (51.6%) patients proceeded to laparotomy, and 256 (44.2%) patients required ICU support. The overall mortality was 33.5%, and the median Injury Severity Score was 48 in patients who died, compared to 22 in those who survived. Increased mortality was associated with concomitant aortic, cardiac, or abdominal injuries. A number of independent risk factors were associated with increased risk of mortality, including concomitant injuries, increased age, and increased Injury Severity Score. Conclusions The incidence of splenic trauma is low, but it accounts for significant mortality. Outcome in the present study was worse in those with advanced age and associated injuries.     

Selective management of blunt hepatic injuries including nonoperative management is a safe and effective strategy

BACKGROUND: The justification and preference for operative versus nonoperative management of hepatic injuries caused by blunt trauma remains ambiguous. This review assesses the outcome of operative and nonoperative management of liver injury after blunt trauma. METHODS: We retrospectively reviewed the demographics, severity of injury, severity of liver injury, associated concomitant injuries, management scheme, and outcome of patients with documented hepatic injury from 1993 to 2003. RESULTS: The overall mortality rate was 9.4%, with 3.7% caused by the liver injury itself. Fifty-nine percent (330 of 561) of liver injuries were of low severity (grades I and II), with an overall mortality rate of 6.6% caused by concomitant injuries and liver-related mortality of 0%. Forty-one percent (231 of 561) of liver injuries were high-severity injuries (grades III, IV, and V). Mortality for nonoperative management of high-severity liver injuries was 2.2%. If operative intervention was required because of hemodynamic instability or concomitant injuries then the mortality rate was significantly higher at 30%. Forty-two of the 378 (11%) liver injuries treated nonoperatively required an adjunctive procedure for successful management. CONCLUSIONS: Selective management of liver injuries presented a low liver-related mortality rate. Low-grade injuries can be managed nonoperatively with excellent results. High-grade injuries can be managed nonoperatively, if operative intervention is not required for hemodynamic instability or associated injuries, with a low mortality. In these patients, adjunctive procedures will be required selectively for successful nonoperative management of high-grade liver injuries. High-grade injuries requiring operative management because of hemodynamic instability or concomitant injuries continue to have significantly higher mortality.     

Thoracic trauma trends in Northern India- single center experience

Introduction

Thoracic trauma comprises 10–15 % of all traumas. The incidence and etiological pattern of chest trauma varies from region to region and is related to cultural and socio-political circumstances. This paper details our experience with thoracic trauma in a North Indian state.

Material & methods

All patients who were hospitalized for thoracic trauma from June 2010 to June 2012 in our hospital were enrolled. Data was collected prospectively and analysed. Factors analysed were age, gender, mode of injury, type of thoracic injury, associated injuries, management modalities, and outcome.

Results

The total number of patients was 250. The male to female ratio was about 10:1. The mean age of patients was 36.62 years. Road Traffic Accident (RTA) was the most common mode of chest injury. Motor-bike accident was the most common type of RTA. Majority of patients were managed with tube thoracostomy (183, 73.2 %). One hundred and eighty nine (75.6 %) patients were discharged after recovery. Ten (4.0 %) patients absconded. In all, 29 (11.6 %) patients died, while 22 (8.8 %) patients left the hospital against medical advice. A significant association between presence of associated injury and outcome was observed (p?<?0.001). We found mortality rate was significantly higher in chest injury associated with neurotrauma and abdominal visceral injury.

Conclusion

Chest trauma is a major health problem since it has high morbidity and mortality rate. The majority of patients with simple chest injuries can be managed by tube thoracostomy. According to our analysis; mortality predictors were: RTAs, blunt chest trauma, unstable hemodynamic status upon arrival, neurotrauma, abdominal visceral injury, flail chest, ventilator use, cardiac contusion and complications of therapy.     

Predictors of outcome in patients requiring surgery for liver trauma

INTRODUCTION: Severe bleeding from liver injury is one of the major causes of mortality in patients with abdominal trauma. The study was undertaken to assess factors that influence outcome following liver trauma. PATIENTS AND METHODS: This is a prospective study of patients with liver injury treated in one surgical ward at King Edward VIII Hospital over a 7-year period (from 1998 to 2004). Data collected included demographics, intra-operative findings, operative management and outcome. RESULTS: Of a total of 478 patients with abdominal trauma, 105 (22%) were found to have liver injuries, of whom only 7 were female. Their mean age was 27.81+/-10.33 years. Injuries were due to firearms (70), stabs (26) and blunt trauma (9). Nineteen patients presented with shock (systolic BP6h in 47 patients. Forty patients required ICU management (38%) and the mean ICU stay was 6.55+/-5.65 days. Twenty patients (19%) needed a re-laparotomy for various reasons. The complication rate was 37% and the mortality rate was 20% (23% for firearms, 44% for blunt trauma and 4% for stabs). The mortality rate in patients with shock was 58% compared to 12% in those who were not shocked (p<0.0001). Mortality rate was 2, 23 and 63% for Injury Severity Score (ISS)20, respectively (group 1 versus group 2 p=0.015; group 1 versus group 3 p<0.0001 and group 2 versus group 3 p=0.001). Mortality rates for delay 6h were 28 and 9%, respectively (p=0.008). Associated injuries led to a higher mortality (3% versus 27%; p=0.006). Hospital stay was 11.27+/-12.09 days. CONCLUSIONS: Liver injuries occurred in 22% of abdominal injuries. Injury mechanism, delay before surgery, shock on admission, grade of injury, associated injury and ISS are significantly associated with outcome.     

Change in outcomes for trauma patients over time: Two decades of a state trauma system

BackgroundTrauma center mortality rates are benchmarked to expected rates of death based on patient and injury characteristics. The expected mortality rate is recalculated from pooled outcomes across a trauma system each year, obscuring system-level change across years. We hypothesized that risk-adjusted mortality would decrease over time within a state-wide trauma system.MethodsWe identified adult trauma patients presenting to Level I and II Pennsylvania trauma centers, 1999–2018, using the Pennsylvania Trauma Outcomes Study. Multivariable logistic regression generated risk-adjusted models for mortality in all patients, and in key subgroups: penetrating torso injury, blunt multisystem trauma, and patients presenting in shock.ResultsOf 162,646 included patients, 123,518 (76.1%) were white and 108,936 (67.0%) were male. The median age was 49 (interquartile range [IQR] 29–70), median injury severity score was 16 (IQR 10–24), and 87.5% of injuries were blunt. Overall, 9.9% of patients died, and compared to 1999, no year had significantly higher adjusted odds of mortality. Overall mortality was significantly lower in 2007–2009 and 2011–2018. Of patients with blunt, multisystem injuries, 17.7% died, and adjusted mortality improved over time. Mortality rates were 24.9% for penetrating torso injury, and 56.9% for shock, with no significant change. Mortality improved for patients with ISS < 25, but not for the most severely injured.ConclusionsOver 20 years, Pennsylvania trauma centers demonstrated improved risk-adjusted mortality rates overall, but improvement remains lacking in high-risk groups despite numerous innovations and practice changes in this time period. Identifying change over time can help guide focus to these critical gaps.     

Blunt Abdominal Trauma Requiring Laparotomy: an Analysis of 342 Polytraumatized Patients

Abstract Introduction: Hemorrhage due to abdominal trauma is one of the most frequent causes of early mortality in polytraumatized patients. Therefore, the initial management of abdominal trauma is an important factor in determining the outcome. The aim of this study was to evaluate the clinical course in multiple trauma patients who sustained abdominal trauma requiring operative intervention. Patients and Methods: In this retrospective analysis, a database containing prospectively collected data on polytraumatized patients from a European level I trauma center was used. The following inclusion criteria were applied: (1) operative intervention for blunt abdominal injuries with positive intraoperative findings, (2) injury severity score (ISS) > 18, and (3) age 16–65 years. Results: The inclusion criteria were met by 342 patients (229 male and 113 female patients, mean ISS 39.9±8.9). The most frequently observed intra-abdominal injuries were to the spleen (62.1%) and the liver (47.7%). The most common extra-abdominal injury observed in combination with abdominal trauma was trauma to the chest (71.9%). One hundred forty-three patients (41%) died during their hospital stay. The most frequent reasons for death were hemorrhagic shock (26.7%), ARDS (27.6%) and head trauma (23.2%). The severity of liver injury correlated positively with mortality. In contrast, no correlation between splenic injuries and mortality was observed. Significantly more deaths were attributed to primarily extra-abdominal injuries (111 patients, 77.6%) and then to intra-abdominal injuries (12 patients, 8.4%). In 20 patients (14%), a combination of intra- and extra-abdominal injuries caused posttraumatic death. Conclusion: Mortality was significantly higher for extra-abdominal injuries and their associated complications compared to intra-abdominal injuries. These findings should be considered in the development of treatment algorithms for blunt trauma.     

Depacked patients who underwent a shortened perihepatic packing for severe blunt liver trauma have a high survival rate: 20 years of experience in a level I trauma center

IntroductionNon-operative management is currently the preferred approach in blunt liver trauma, including high grade liver lesions. However, hemodynamic instability imposes the need for an emergency laparotomy, with a perihepatic packing (PHP) to control liver bleeding in most cases. Our retrospective study aimed to assess the outcomes of liver trauma patients who underwent a shortened PHP.MethodsAll consecutive patients who underwent PHP for blunt liver trauma from 1998 to 2019 in our Level I trauma center were included in the study. Unstable patients with severe liver trauma were transferred to the operating room without any delay, and a collective decision was made to perform abbreviated laparotomy to pack the liver. Demographics, perioperative data, postoperative outcomes, and mortality were retrospectively collected, and survivors and deceased patients were compared with a paired t-test.ResultsFifty-nine patients of 206 patients admitted with severe liver injuries were treated with shortened PHP. Thirty-four (57.6%) patients died, including 26 (76.5%) within the first 24 h. Twelve (20.3%) patients had a selective hepatic embolization and eight (13.6%) had an extrahepatic embolization. Forty-eight patients had an extra abdominal associated injury. This was not a predictive factor of mortality. The removal of packing was performed in 24 patients within 72 h after laparotomy, with an 80% survival rate in these patients.ConclusionShortened PHP is an effective strategy for controlling liver bleeding in severe hepatic trauma. The mortality rate of these patients is high, but after the removal of packing, the survival is good.     

The Epidemiology of and Outcome from Pancreatoduodenal Trauma in the UK, 1989–2013

Introduction

Pancreatoduodenal (PD) injury is an uncommon but serious complication of blunt and penetrating trauma, associated with high mortality. The aim of this study was to assess the incidence, mechanisms of injury, initial operation rates and outcome of patients who sustained PD trauma in the UK from a large trauma registry, over the period 1989–2013.

Methods

The Trauma Audit and Research Network database was searched for details of any patient with blunt or penetrating trauma to the pancreas, duodenum or both.

Results

Of 356,534 trauma cases, 1,155 (0.32%) sustained PD trauma. The median patient age was 27 years for blunt trauma and 27.5 years for penetrating trauma. The male-to-female ratio was 2.5:1. Blunt trauma was the most common type of injury seen, with a ratio of blunt-to-penetrating PD injury ratio of 3.6:1. Road traffic collision was the most common mechanism of injury, accounting for 673 cases (58.3%). The median injury severity score (ISS) was 25 (IQR: 14–35) for blunt trauma and 14 (IQR: 9–18) for penetrating trauma. The mortality rate for blunt PD trauma was 17.6%; it was 12.2% for penetrating PD trauma. Variables predicting mortality after pancreatic trauma were increasing age, ISS, haemodynamic compromise and not having undergone an operation.

Conclusions

Isolated pancreatic injuries are uncommon; most coexist with other injuries. In the UK, a high proportion of cases are due to blunt trauma, which differs from US and South African series. Mortality is high in the UK but comparison with other surgical series is difficult because of selection bias in their datasets.

Purpose

To evaluate massive transfusion protocol practices by trauma type at a level I trauma center.

Increased reduction in exsanguination rates leaves brain injury as the only major cause of death in blunt trauma

IntroductionCentral nervous system (CNS) related injuries and exsanguination have been the most common causes of death in trauma for decades. Despite improvements in haemorrhage control in recent years exsanguination is still a major cause of death. We conducted a prospective database study to investigate the current incidence of haemorrhage related mortality.Materials and methodsA prospective database study of all trauma patients admitted to an urban major trauma centre between January 2007 and December 2016 was conducted. All in-hospital trauma deaths were included. Cause of death was reviewed by a panel of trauma surgeons. Patients who were dead on arrival were excluded. Trends in demographics and outcome were analysed per year. Further, 2 time periods (2007–2012 and 2013–2016) were selected representing periods before and after implementation of haemostatic resuscitation and damage control procedures in our hospital to analyse cause of death into detail.Results11,553 trauma patients were admitted, 596 patients (5.2%) died. Mean age of deceased patients was 61 years and 61% were male. Mechanism of injury (MOI) was blunt in 98% of cases. Mean ISS was 28 with head injury the most predominant injury (mean AIS head 3.4). There was no statistically significant difference in sex and MOI over time. Even though deceased patients were older in 2016 compared to 2007 (67 vs. 46 years, p < 0.001), mortality was lower in later years (p = 0.02). CNS related injury was the main cause of death in the whole decade; 58% of patients died of CNS in 2007–2012 compared to 76% of patients in 2013–2016 (p = 0.001). In 2007–2012 9% died of exsanguination compared to 3% in 2013–2016 (p = 0.001).DiscussionIn this cohort in a major trauma centre death by exsanguination has decreased to 3% of trauma deaths. The proportion of traumatic brain injury has increased over time and has become the most common cause of death in blunt trauma. Besides on-going prevention of brain injury future studies should focus on treatment strategies preventing secondary damage of the brain once the injury has occurred     

Selective management of blunt splenic trauma

During a recent 8-year period, 235 patients with documented blunt splenic trauma were treated. After exclusion of 39 patients with early deaths (19 dead on arrival, nine died in emergency room, and 11 died in operating room), the 196 remaining patients were treated in accordance with an evolving selective management program. Definitive management included splenectomy in 117 patients (59.7%), repair in 32 (16.3%), and nonoperative treatment in 47 (24%). A spectrum of blunt splenic trauma, as manifested by the degree of associated injuries (Injury Severity Scores), hemodynamic status, and blood transfusion requirements, was identified and permitted application of a rational selective management program that proved safe and effective for all age groups. Comparative analysis of the three methods of treatment demonstrated differences that were more a reflection of the overall magnitude of total bodily injury sustained rather than the specific manner in which any injured spleen was managed. Retrospective analysis of 19 nonoperative management failures enabled establishment of the following selection criteria for nonoperative management: absolute hemodynamic stability; minimal or lack of peritoneal findings; and maximal transfusion requirement of 2 units for the splenic injury. With operative management, splenorrhaphy is preferred, but it was often precluded by associated life-threatening injuries or by technical limitations. Of 42 attempted splenic repairs, ten (24%) were abandoned intraoperatively. There were no late failures of repair. In many cases of blunt splenic trauma, splenectomy still remains the most appropriate course of action.
