Clinical decompensation after trauma laparotomy: It's probably not a pulmonary embolus

Introduction Computed Tomography (CT) to rule out pulmonary embolus (PE) is often ordered during post-trauma laparotomy clinical decompensation (CD) involving fever, tachycardia, tachypnea, and/or leukocytosis. We hypothesize this diagnostic modality is low-yield in the postoperative period when surgery-related sequelae are more probable.Methods This is a single-center retrospective cohort study of patients who underwent trauma laparotomy and had subsequent CT for CD from March 19, 2019 to June 30, 2022. Descriptive statistics and multiple logistic regression were performed. The primary outcome was saddle and lobar PE incidence.Results 1032 adult patients underwent trauma laparotomy with 434 undergoing CT for CD: 137 CT abdomen and pelvis only, 30 CTPE, 265 both. The majority (80.2 %) was male, age 33[interquartile range (IQR) 24–45], suffered penetrating mechanism (57 %), and had ISS 23[IQR16–30]. Injuries at laparotomy included 47 % solid organ, 62 % GI tract, 7 % biliary, 11 % vascular, and 42 % other. 176 (41 %) required damage control laparotomy. Median time to CT post-laparotomy was 174 h [111–235] with saddle and lobar PE in 3 (1 %), peripheral PE 18 (5 %), and abdominal abscess, leak, fluid, or pseudoaneurysm in 222 (51 %). Clinical management was altered (40 %) by antibiotics, therapeutic anticoagulation, drainage, aspiration, filter, thrombectomy, or surgical operation. Patients for whom CT findings changed management were more likely to have had GI tract surgery (69% vs 57 %, p = 0.021), higher white blood cell (WBC) (16.4 [13.1–20.5] vs 15.1 [9.9–19.5], p = 0.002), more hours between CT and laparotomy (184 [141–245] vs 162 [89–230], p = 0.002), and lower mortality (2% vs 8 %, p = 0.008). In-hospital mortality was 5 %; none were PE-related. Predictors of clinical intervention required based on CT imaging were GI tract injury (AOR: 1.65, p = 0.0182), and elevated WBC (AOR: 1.038, p = 0.010Conclusion Saddle and lobar PE incidence post-trauma laparotomy is low. SIRS-type symptoms prompting postoperative CT commonly have no procedural or antibiotic requirement. Postoperative decompensation is more likely related post-operative complications, and less likely a PE.

Laparotomy for Traumatic Splenic Injury: Should we Increase our Efforts to Preserve the Spleen?

Abstract Background In trauma laparotomy the spleen is removed very liberally, and often little effort is made for splenic preservation. Aims The aim of this study was to assess the effect of surgical management (splenic repair vs. splenectomy) on outcomes in patients undergoing trauma laparotomy. Methods This is a trauma registry (TQIP) study (2013–2019), including adult patients with severe splenic injuries (grades III-V) undergoing trauma laparotomy. Characteristics and outcomes of patients who underwent splenic repair vs. splenectomy within 6 hours of admission were compared using different statistical approaches, i.e. 1:1 exact matching with consecutive conditional logistic regression analysis as primary analysis, multivariable logistic regression, propensity score matching and inverse-probability weighting as sensitivity analyses. The primary outcome was in-hospital mortality. Results A total of 11,247 patients with a severe splenic injury undergoing trauma laparotomy within 6 hours of admission were identified. Of these, 10,820 (96.2%) patients underwent splenectomy and 427 (3.8%) patients splenic repair within 6 hours of admission. Among patients who underwent an initial splenic salvage procedure, 23 (5.3%) patients underwent a splenectomy during the subsequent hospital stay. 400 patients with splenic preservation, were matched with 400 patients who underwent splenectomy (matched for age, sex, hypotension, trauma mechanism as well as AIS spleen grades 3,4,5 and AIS groups (AIS 0-2, AIS 3, AIS 4-5) for head, face, neck, thorax, spine, and lower & upper extremity). The mortality was significantly lower in the group of patients with splenic repair (6.5% vs 12.8%, p=0.002). The mortality benefit was subsequently verified by conditional regression analysis (aOR 0.4, CI 95% 0.2; 0.9). Multivariable logistic regression, propensity score matching, and inverse-probability weighting confirmed the lower mortality in the splenic repair group. Conclusion In trauma laparotomy splenic repair was independently associated with lower mortality compared with splenectomy. Splenectomy was required in approximately 5% of the patients after initial splenic repair. The findings provide evidence that efforts for spleen preservation in trauma laparotomy should be considered in selected cases.

Impact of Intra-Operative Shock and Resuscitation on Surgical Site Infections After Trauma Laparotomy.

Background: Patients undergoing trauma laparotomy experience high rates of surgical site infection (SSI). Although intra-operative shock is a likely contributor to SSI risk, little is known about the relation between shock, intra-operative restoration of physiologic normalcy, and SSI development. Patients and Methods: A retrospective review of trauma patients who underwent emergent definitive laparotomy was performed. Using shock index and base excess at the beginning and end of laparotomy, patients were classified as normal, persistent shock, resuscitated, or new shock. Univariable and multivariable analyses were performed to identify predictors of organ/space SSI, superficial/deep SSI, and any SSI. Results: Of 1,191 included patients, 600 (50%) were categorized as no shock, 248 (21%) as resuscitated, 109 (9%) as new shock, and 236 (20%) as persistent shock, with incidence of any SSI as 51 (9%), 28 (11%), 26 (24%), and 32 (14%), respectively. These rates were similar in organ/space and superficial/deep SSIs. On multivariable analysis, resuscitated, new shock, and persistent shock were associated with increased odds of organ/space SSI (odds ratio [OR], 2.2; 95% confidence interval [CI], 1.3-3.5; p < 0.001) and any SSI (OR, 2.0; 95% CI, 1.4-3.2; p < 0.001), but no increased risk of superficial/deep SSI (OR, 1.4; 95% CI, 0.8-2.6; p = 0.331). Conclusions: Although the trajectory of physiologic status influenced SSI, the presence of shock at any time during trauma laparotomy, regardless of restoration of physiologic normalcy, was associated with increased odds of SSI. Further investigation is warranted to determine the relation between peri-operative shock and SSI in trauma patients.

Trauma Laparotomy for the Cirrhotic Patient: An Outcome-Based Analysis

IntroductionThere is a lack of large-scale data on outcomes of cirrhotic patients undergoing trauma laparotomy. We aimed to compare outcomes of cirrhotic versus noncirrhotic trauma patients undergoing laparotomy. MethodsWe analyzed 2018 American College of Surgeons Trauma Quality Improvement Program. We included blunt trauma patients (≥18 y) who underwent a laparotomy. Patients who were transferred, dead on arrival, or had penetrating injuries were excluded. Patients were matched in a 1:2 ratio (cirrhotic and noncirrhotic). Outcomes included mortality, complications, failure to rescue, transfusion requirements, and hospital and intensive care unit (ICU) lengths of stay. Multivariable backward stepwise regression analysis was performed. ResultsFour hundred and seventy-one patients (cirrhotic, 157; noncirrhotic, 314) were matched. Mean age was 57 ± 15 y, 78% were male, and median injury severity score was 24. Cirrhotic patients had higher rates of mortality (60% versus 30%, P value <0.001), complications (49% versus 37%; P value = 0.01), failure to rescue (66% versus 36%, P value<0.001), and pRBC (units, median, 11 [7-18] versus 7 [4-11], P value <0.001) transfusion requirements. There were no significant differences in hospital and intensive care unit (ICU) lengths of stay (P value ≥0.05). On multivariate analysis, increasing age (adjusted odds ratio [aOR] 1.02, P value <0.001), Glasgow Coma Scale score ≤8 at presentation (aOR 3.3, P value <0.001), and total splenectomy (aOR 5.7, P value <0.001) were associated with higher odds of mortality. Platelet transfusion was associated with lower odds of mortality (aOR 0.84, P value = 0.044). ConclusionsOn a national scale, mortality following trauma laparotomy is twice as high for cirrhotic patients compared to noncirrhotic patients with higher rates of major complications and failure to rescue. Our finding of a protective effect of platelet transfusion may be explained by the platelet dysfunction associated with cirrhosis. Liver cirrhosis among trauma patients warrants heightened surveillance.

A Xiphoid Elongation Following a Trauma Laparotomy: A Case Report

Xiphoid elongation is a rare phenomenon where the xiphoid process elongates after stimuli such as surgery, physical therapy, or trauma. We report on a 47-year-old male involved in a traffic accident who went into cardiac arrest. He received ongoing cardiopulmonary resuscitation for nine minutes before recovery of cardiac rhythm, and transfer from a local hospital to the trauma center. He received management for hypotensive shock which was temporarily corrected using Resuscitative Endovascular Balloon Occlusion of the Aorta, and underwent trauma laparotomy in which ileocolic artery ligation and a splenectomy were performed. Six months later, the patient reported epigastric discomfort when he bent over. A hard, linear mass was palpated along the upper midline incision scar and a computed tomography scan showed an elongated xiphoid process (10 cm). The patient underwent surgical excision, and electrocauterization of the xiphoid process. This is a rare case of xiphoid elongation following multiple stimuli to the xiphoid process.

WE7.1 Getting it right first time: a standardised approach to closure of trauma laparotomy

Abstract Aims Surgical site infection (SSI) has been reported between 12–14% following trauma laparotomy. It became apparent in a regional trauma center that 25% of trauma patients required an MRI within 10 days of admission and point of potential trauma laparotomy leading to the morbidity of non-MRI compatible clip removal and reclosure of the wound. The aim was to ensure all trauma laparotomies underwent closure with MRI compatible clips. Methods A retrospective data collection was performed of patients undergoing trauma laparotomies between July and December 2021. Data was collected on wound morbidity, if an MRI was required and if patients required clip removal. Results 16 patients underwent trauma laparotomy between July-December 2021. 25% of these patients had an MRI performed within 10 days of their laparotomy, (median 3days), 3 of these required removal of clips. 1 of these patients developed a SSI requiring negative pressure therapy. Conclusion This QI project led to the introduction of a unit approved damage control laparotomy trolley with all potential essential equipment to allow instant availability including only MRI compatible clips. The project also led to a qualitative improvement of improved team morale due to teaching sessions for theatre nursing staff on importance and use of all these instruments. Outcome measure data is currently being collected to ensure compliance with trolley usage and MRI compatible clips negating the morbidity of reclosure of wound as well as the process measure of staff satisfaction of equipment knowledge and availability during a trauma laparotomy.

A characterization of trauma laparotomies in a scandinavian setting: an observational study

BackgroundDespite treatment advances, trauma laparotomy continuous to be associated with significant morbidity and mortality. Most of the literature originates from high volume centers, whereas patient characteristics and outcomes in a Scandinavian setting is not well described. The objective of this study is to characterize treatments and outcomes of patients undergoing trauma laparotomy in a Scandinavian setting and compare this to international reports.MethodsA retrospective study was performed in the Copenhagen University Hospital, Rigshospitalet (CUHR). All patients undergoing a trauma laparotomy within the first 24 h of admission between January 1st 2019 and December 31st 2020 were included. Collected data included demographics, trauma mechanism, injuries, procedures performed and outcomes.ResultsA total of 1713 trauma patients were admitted to CUHR of which 98 patients underwent trauma laparotomy. Penetrating trauma accounted for 16.6% of the trauma population and 66.3% of trauma laparotomies. Median time to surgery after arrival at the trauma center (TC) was 12 min for surgeries performed in the Emergency Department (ED) and 103 min for surgeries performed in the operating room (OR). A total of 14.3% of the procedures were performed in the ED. A damage control strategy (DCS) approach was chosen in 18.4% of cases. Our rate of negative laparotomies was 17.3%. We found a mortality rate of 8.2%. The total median length of stay was 6.1 days.ConclusionThe overall rates, findings, and outcomes of trauma laparotomies in this Danish cohort is comparable to reports from similar Western European trauma systems.

Should We Perform Incidental Appendectomy in Trauma Patients Undergoing Laparotomy?

Incidental appendectomy (IA) is sometimes performed in patients undergoing abdominal operations to prevent subsequent development of appendicitis. Patients who undergo laparotomy for major abdominal trauma are at high risk of developing dense adhesions, increasing the risk of future operations. Therefore, there is a potential benefit to IA for patients undergoing trauma laparotomy. We performed a retrospective review of patients who underwent IA during laparotomy for abdominal trauma at a Level 1 trauma center between January 2010, and June 2020. Twenty-three patients underwent IA; they tended to be young (33.7 ± 18.9years) and male (87%) with 12 penetrating and 11 blunt injuries. Regarding indications, 13 had no documented intra-operative abnormalities of the appendix, 6 patients had a fecalith, and 3 had trauma to the appendix. One patient's appendix was adhered to the peritoneum and one patient had unusual anatomic location. Only one patient developed an appendiceal stump leak after IA.

In for a Penny, in for a Pound: Obesity weighs heavily on both cost and outcome in trauma

BackgroundThe current literature offers mixed conclusions regarding the effect of increased body mass index (BMI) on outcomes after trauma laparotomy. This study evaluated the impact of obesity on outcomes and cost for patients undergoing trauma laparotomy at a level 1 trauma center. Study designData on patients requiring trauma laparotomy in 2016 were prospectively collected and patients were stratified by BMI. Statistical analyses were used to determine variables significantly associated with patient morbidity and length of stay. Results313 patients underwent trauma laparotomy: 225 non-obese, 69 obese, and 19 morbidly obese. Obese and morbidly obese patients had longer ICU and hospital lengths of stay (LOS), more ventilator days, larger hospital costs, and higher morbidity compared to non-obese patients. Obesity was an independent predictor for patient morbidity, ICU, and hospital LOS. ConclusionsMorbidity and length of stay increased with worsening obesity after trauma laparotomy, contributing to rising hospital costs.

Predictive factors of mortality in damage control surgery for abdominal trauma.

damage control surgery (DCS) is well recognized as a surgical strategy for patients sustaining severe abdominal trauma. Literature suggests the indications, operative times, therapeutic procedures, laboratory parameters and intraoperative findings have a direct bearing on the outcomes. to analyze the clinical profile of patients undergoing DCS and determine predictors of morbidity and mortality. a retrospective cohort study was conducted on all patients undergoing DCS following abdominal trauma from November 2015 and December 2021. Data on subjects' demographics, baseline presentation, mechanism of injury, associated injuries, injury severity scores, laboratory parameters, operative details, postoperative complications, length of stay and mortality were assessed. A binary logistic regression analysis was performed to determine potential risk factors for mortality. During the study period, 696 patients underwent trauma laparotomy. Of these, 8.9% (n=62) were DCS, with more than 80% due to penetrating mechanisms. Overall mortality was 59.6%. In the logistic regression stratified by survival, several variables were significantly associated with mortality, including hypotension, and altered mental status at admission, intraoperative cardiorespiratory arrest, need for resuscitative thoracotomy, metabolic acidosis, hyperlactatemia, coagulopathy, fibrinolysis, and severity of the trauma injury scores. DCS may be appropriate in critically injured patients; however, it remains associated with significant morbidity and high mortality, even at specialized trauma care centers. From pre and postoperative clinical and laboratory parameters, it was possible to predict the risk of death in the studied sample.

Intra-Abdominal Hemorrhage Control: The Need for Routine Four-Quadrant Packing Explored.

Routine four-quadrant packing (4QP) for hemorrhage control immediately upon opening is a standard practice for acute trauma laparotomy. The aim of this study was to evaluate the utility of 4QP for bleeding control in acutely injured patients undergoing trauma laparotomy. Retrospective single-center study (01/2015-07/2019), including adult patients who underwent trauma laparotomy within 4h of admission. Only patients with active intra-abdominal hemorrhage, defined as bleeding within the peritoneal cavity or expanding retroperitoneal hematoma, were considered for analysis. Bleeding sources were categorized anatomically: liver/retrohepatic inferior vena cava (RIVC), spleen, retroperitoneal zones 1, 2 and 3, mesentery and others. Hemorrhage was further categorized as originating from a single bleeding site (SBS) or from multiple bleeding sites (MBS). The effectiveness of directed versus 4QP was evaluated for bleeding from the liver/RIVC, spleen and retroperitoneal zone 3, areas that are potentially compressible. Directed packing was defined as indicated if the bleeding was restricted to one of the anatomic sites suitable for packing, 4QP was defined as indicated if ≥ 2 of the anatomic sites suitable for packing were bleeding. During the study time frame, 924 patients underwent trauma laparotomy, of which 148 (16%) had active intra-abdominal hemorrhage. Of these, 47% had a SBS and 53% had MBS. The liver/RIVC was the most common bleeding source in both patients with SBS (42%) and in patients with MBS (54%). According to our predefined indications, 22 of 148 patients (15%) would have benefitted from initial 4QP, 90 of 148 patients (61%) from directed packing and 36 of 148 patients (24%) packing would not have been of any value. Routine four-quadrant packing is frequently practiced. However, this is only required in a small proportion of patients undergoing trauma laparotomy. Directed packing can be equally effective, saves time and decreases the risk of iatrogenic injury from unnecessary packing.

Complications and Failure to Rescue After Abdominal Surgery for Trauma in Obese Patients

BackgroundAlthough obesity is considered an epidemic in the United States, there is mixed evidence regarding the impact of obesity on outcomes after traumatic injury and major surgery. We hypothesized that obese patients undergoing trauma laparotomy would be at increased risk of failure to rescue (FTR), defined as death after a complication. MethodsWe analyzed trauma registry data for adult patients who underwent abdominal exploration for trauma at all 30 level I and II Pennsylvania trauma centers, 2011-2014. We used competing risks regression to identify significant risk factors for complications. We used multivariable logistic regression to identify significant risk factors for FTR. ResultsOf 95,806 admitted patients, 15,253 (15.9%) were categorized as obese. Overall, 3228 (3.4%) underwent laparotomy, including 2681 (83.1%) nonobese and 547 (17.0%) obese patients. Among obese patients, 47.2% had at least one complication and 28.7% had two or more complications, compared with 33.5% and 18.7% of nonobese patients, respectively. The most common complication was pneumonia (15.0% of obese and 10.5% of nonobese patients; P = 0.003), followed by sepsis (8.8% versus 4.2%; P < 0.001) and deep vein thrombosis (8.4% versus 5.9%; P < 0.001). Obesity was independently associated with complications (hazard ratio, 1.4; 95% confidence interval, 1.2-1.6). In multivariable analysis, obesity was not associated with FTR (odds ratio, 1.3; 95% confidence interval, 0.9-2.0). ConclusionsObesity is a risk factor for complications after traumatic injury but not for FTR. The increased risk of complications may reflect processes of care that are not attuned to the needs of this population, offering opportunities for improvement in care.

Obesity associated with increased postoperative pulmonary complications and mortality after trauma laparotomy

BackgroundPatient-related risk factors for the development of postoperative pulmonary complications (PPCs) include age ≥ 60-years, congestive heart failure, hypoalbuminemia and smoking. The effect of obesity is unclear and has not been shown to independently increase the likelihood of PPCs in trauma patients undergoing trauma laparotomy. We hypothesized the likelihood of mortality and PPCs would increase as body mass index (BMI) increases in trauma patients undergoing trauma laparotomy.MethodsThe Trauma Quality Improvement Program (2010–2016) was queried to identify trauma patients ≥ 18-years-old undergoing trauma laparotomy within 6-h of presentation. A multivariable logistic regression analysis was used to determine the likelihood of PPCs and mortality when stratified by BMI.ResultsFrom 8,330 patients, 2,810 (33.7%) were overweight (25–29.9 kg/m2), 1444 (17.3%) obese (30–34.9 kg/m2), 580 (7.0%) severely obese (35–39.9 kg/m2), and 401 (4.8%) morbidly obese (≥ 40 kg/m2). After adjusting for covariates including age, injury severity score, chronic obstructive pulmonary disease, smoking, and rib/lung injury, the likelihood of PPCs increased with increasing BMI: overweight (OR = 1.37, CI 1.07–1.74, p = 0.012), obese (OR = 1.44, CI 1.08–1.92, p = 0.014), severely obese (OR = 2.20, CI 1.55–3.14, p < 0.001), morbidly obese (OR = 2.42, CI 1.67–3.51, p < 0.001), compared to those with normal BMI. In addition, the adjusted likelihood of mortality increased for the morbidly obese (OR = 2.60, CI 1.78–3.80, p < 0.001) compared to those with normal BMI.ConclusionObese trauma patients undergoing emergent trauma laparotomy have a high likelihood for both PPCs and mortality, with morbidly obese trauma patients having the highest likelihood for both. This suggests obesity should be accounted for in risk prediction models of trauma patients undergoing laparotomy.Electronic supplementary materialThe online version of this article (10.1007/s00068-020-01329-w) contains supplementary material, which is available to authorized users.

Obesity Associated with Increased Postoperative Pulmonary Complications and Mortality after Trauma Laparotomy

Patient-related risk factors for the development of postoperative pulmonary complications (PPCs) include age ≥ 60-years, congestive heart failure, hypoalbuminemia and smoking. The effect of obesity is unclear and has not been shown to independently increase the likelihood of PPCs in trauma patients undergoing trauma laparotomy. We hypothesized the likelihood of mortality and PPCs would increase as body mass index (BMI) increases in trauma patients undergoing trauma laparotomy. The Trauma Quality Improvement Program (2010–2016) was queried to identify trauma patients ≥ 18-years-old undergoing trauma laparotomy within 6-h of presentation. A multivariable logistic regression analysis was used to determine the likelihood of PPCs and mortality when stratified by BMI. From 8,330 patients, 2,810 (33.7%) were overweight (25–29.9 kg/m2), 1444 (17.3%) obese (30–34.9 kg/m2), 580 (7.0%) severely obese (35–39.9 kg/m2), and 401 (4.8%) morbidly obese (≥ 40 kg/m2). After adjusting for covariates including age, injury severity score, chronic obstructive pulmonary disease, smoking, and rib/lung injury, the likelihood of PPCs increased with increasing BMI: overweight (OR = 1.37, CI 1.07–1.74, p = 0.012), obese (OR = 1.44, CI 1.08–1.92, p = 0.014), severely obese (OR = 2.20, CI 1.55–3.14, p < 0.001), morbidly obese (OR = 2.42, CI 1.67–3.51, p < 0.001), compared to those with normal BMI. In addition, the adjusted likelihood of mortality increased for the morbidly obese (OR = 2.60, CI 1.78–3.80, p < 0.001) compared to those with normal BMI. Obese trauma patients undergoing emergent trauma laparotomy have a high likelihood for both PPCs and mortality, with morbidly obese trauma patients having the highest likelihood for both. This suggests obesity should be accounted for in risk prediction models of trauma patients undergoing laparotomy.

Quality Improvement of Damage Control Laparotomy: Impact of the Establishment of a Single Korean Regional Trauma Center.

Damage control laparotomy (DCL) is a lifesaving technique to minimize the lethal triad of coagulopathy, hypothermia, and acidosis. The government has nominated and supported our center as one of the regional trauma centers of South Korea since 2014. This study aimed to investigate the improving outcomes of patients undergoing DCL before and after the establishment of the trauma center. The period from January 2011 to December 2017 was divided into pre-trauma center (pre-TC) (2011-2013) and trauma center (TC) (2014-2017) periods. Multivariable logistic regression was performed to identify the risk factors and risk-adjusted cumulative sum (RA-CUSUM), and graphs were used to monitor the change in mortality. Of the 485 patients who underwent trauma laparotomy, DCL was performed for 119 patients (24.5%). The operation time (99 vs. 80min, p = 0.022), time from admission to operation (125 vs. 112min, p = 0.010), time from admission to first treatment (119 vs. 99min, p = 0.004), and time from admission to first transfusion (70 vs. 52min, p = 0.009) were significantly shortened in the TC period. The ratio of plasma to packed red blood cells in massive transfusions (≥PRBCs 10 units within the first 24h) was significantly increased in the TC period (0.56 vs. 0.72, p = 0.004). RA-CUSUM curves revealed that the risk-adjusted 30-day mortality improved and then plateaued in the TC period. After the implementation of a trauma center, more prompt intervention and damage control resuscitation could be achieved. Moreover, risk-adjusted mortality of DCL was improved.

Surgical site infections after trauma laparotomy. An observational study from a major trauma center in Saudi Arabia.

Objectives:To determine the incidence of surgical site infection (SSI) after trauma laparotomy and evaluate variables on presentation to the emergency department (ED) associated with the development of SSI.Methods:A retrospective cohort study was undertaken of patients presenting directly from the scene who underwent trauma laparotomy between January 2016 and December 2017. The primary outcome variable was SSI, as defined by the Centers for Disease Control and Prevention guideline. A univariate assessment with demographics, vital signs, and acute management was reported.Results:A total of 70 patients were included for data analysis. Of these, 9 (12.9%; 95% confidence interval (CI): 6.9-22.7%) patients developed SSI, including 5 patients with bowel injury (small bowel; n=3, colonic injuries; n=2). Most cases were diagnosed after 7 days in the hospital. All patients developed superficial incisional (skin and subcutaneous tissue) SSI. No predetermined variables, including bowel injury (p=0.08) or duration of surgery (p=0.09), demonstrated a statistically significant association with the development of SSI.Conclusion:Rates of SSI after trauma laparotomy were similar to previous reports from other centers. Surgical site infection after trauma laparotomy was diagnosed at a delayed time point after surgery, and patient demographics, injury characteristics, and acute surgical management did not appear to be associated with subsequent diagnosis of SSI.

Outcomes following trauma laparotomy for hypotensive trauma patients: A UK military and civilian perspective

The management of trauma patients has changed radically in the last decade, and studies have shown overall improvements in survival. However, reduction in mortality for the many may obscure a lack of progress in some high-risk patients. We sought to examine the outcomes for hypotensive patients requiring laparotomy in UK military and civilian cohorts. We undertook a review of two prospectively maintained trauma databases: the UK Joint Theatre Trauma Registry for the military cohort (February 4, 2003, to September 21, 2014) and the trauma registry of the Royal London Hospital major trauma center (January 1, 2012, to January 1, 2017) for civilian patients. Adults undergoing trauma laparotomy within 90 minutes of arrival at the emergency department (ED) were included. Hypotension was present on arrival at the ED in 155 (20.4%) of 761 military patients. Mortality was higher in hypotensive casualties (25.8% vs. 9.7% in normotensive casualties; p < 0.001). Hypotension was present on arrival at the ED in 63 (35.7%) of 176 civilian patients. Mortality was higher in hypotensive patients (47.6% vs. 12.4% in normotensive patients; p < 0.001). In both cohorts of hypotensive patients, neither the average injury severity, the prehospital time, the ED arrival systolic blood pressure, nor mortality rate changed significantly during the study period. Despite improvements in survival after trauma for patients overall, the mortality for patients undergoing laparotomy who arrive at the ED with hypotension has not changed and appears stubbornly resistant to all efforts. Specific enquiry and research should continue to be directed at this high-risk group of patients. Prognostic/Epidemiologic, level IV.

Caring for critically injured children: An analysis of 56 pediatric damage control laparotomies.

Injury is the leading cause of death in children under 18 years. Damage control principles have been extensively studied in adults but remain relatively unstudied in children. Our primary study objective was to evaluate the use of damage control laparotomy (DCL) in critically injured children. An American College of Surgeons-verified Level 1 trauma center review (1996-2013) of pediatric trauma laparotomies was undertaken. Exclusion criteria included: age older than 18 years, laparotomy for abdominal compartment syndrome or delayed longer than 2 hours after admission. Demographics, mechanism, resuscitation variables, injuries, need for DCL, and outcomes were evaluated. Independent t test, Mann-Whitney U test, Fisher's exact test, and single-factor analysis of variance assessed statistical significance. Study endpoints were hospital survival and DCL complications. Of 371 children who underwent trauma laparotomy, the median age (IQR; LQ-UQ) age was 16 (5; 11-17) years. Most (73%) were male injured by blunt mechanism (65%). Fifty-six (15%) children (Injury Severity Score [ISS], 33 (25; 17-42), pediatric trauma score 5 (6; 2-8), penetrating abdominal trauma index score [PATI] 29 (32; 12-44)) underwent DCL after major solid organ (63%), vascular (36%), thoracic (38%) and pelvic (36%) injury. DCL patients were older (16.5 (4; 14-18) vs. 16 (7; 10-17)) and were more severely injured (ISS, 33 [25; 17-42] vs. 16 [16; 9-25]), requiring greater intraoperative packed red blood cell transfusion (8 [13; 3.5-16.5] vs. 1 (0; [0-1] units) than definitive laparotomy counterparts. Nonsurvivors arrived in severe physiologic compromise (base deficit, 17 [17; 8-25] vs. 7 [4; 4-8]), requiring more frequent preoperative blood product transfusion (67% vs. 10%) after comparable injury (ISS survivors, 36 [23; 18-41] vs. nonsurvivors 26 (7; 25-32), p = 0.8880). Fifty-five percent of DCL patients survived (length of stay, 26 [21; 18-39] days) requiring 3 (2; 2-4) laparotomies during 4 (6; 2-8) days until closure (fascial, 90%; vicryl/split thickness skin grafting, 10%). DCL complications (surgical site infection, 18%; dehiscence, 2%; enterocutaneous fistula, 2%) were analyzed. When stratified by age (<15 years vs. 15-18 years) and period (1996-2006 vs. 2007-2013), no differences were found in injury severity or DCL outcomes (p > 0.05). After controlling for DCL, age, and gender, multivariate analysis indicated only ISS (odds ratio, 1.10 [95% confidence interval, 1.01 - 1.19], p = 0.0218) and arrival systolic blood pressure (odds ratio, 0.96 [95% confidence interval, 0.93-0.99], p = 0.0254) predicted mortality after severe injury. DCL is a proven, lifesaving surgical technique in adults. This report is the first to analyze the use of DCL in children with critical abdominal injuries. With similar survival and morbidity rates as critically injured adults, DCL merits careful consideration in children with critical abdominal injuries. Therapeutic study, level IV.
