Anticoagulation is Associated with Increased Mortality in Splenic Injuries.

INTRODUCTION: Anticoagulation (AC) is associated with worse outcomes after trauma in some but not all studies. To further investigate the effect of AC on outcomes in patients with splenic injury, we analyzed the Trauma Quality Programs Participant Use File (PUF) METHODS: The 2017 PUF was used to identify adult (18+ y) with all mechanisms and grades of splenic injury. Demographics, comorbidities, hospital course and outcomes were compared between AC and non-AC patients. RESULTS: A total of 18,749 patients were included, 622 were on AC. The AC patients were older but had comparable gender composition to non-AC patients. Injury Severity Score (18.2 versus 22.5) and rates of serious (AIS ≥ 3) injury were all lower in the AC group (P = 0.001). AC patients received fewer units of RBC (5.7 versus 8.0 units, P < 0.001) and FFP (3.9 versus 5.4 units, P < 0.001) in the first 24 h but underwent angiography at similar rates (23.6 versus 24.5%, P = 0.8). Among those who underwent angiography, patients were more likely to undergo embolization if they were on AC (89.7 versus 73.9%, P = 0.04). Rates of splenic surgery were comparable (19.3 versus 21.5%, P = 0.2) between AC versus non-AC patients. Median LOS was longer in AC patients (6.3 versus 5.6 d, P = 0.002). AC patients had a higher mortality (13.3 versus 7.0%, P = 0.001). In a multivariable binary logistic regression, AC was an independent risk factor for mortality with OR 1.4 (95% CI: 1.1-1.9) CONCLUSIONS: Anticoagulation is associated with increased mortality in patients with splenic injury.

Metabolic acidosis and the role of unmeasured anions in critical illness and injury.

Acid-base disorders are frequently present in critically ill patients. Metabolic acidosis is associated with increased mortality, but it is unclear whether as a marker of the severity of the disease process or as a direct effector. The understanding of the metabolic component of acid-base derangements has evolved over time, and several theories and models for precise quantification and interpretation have been postulated during the last century. Unmeasured anions are the footprints of dissociated fixed acids and may be responsible for a significant component of metabolic acidosis. Their nature, origin, and prognostic value are incompletely understood. This review provides a historical overview of how the understanding of the metabolic component of acid-base disorders has evolved over time and describes the theoretical models and their corresponding tools applicable to clinical practice, with an emphasis on the role of unmeasured anions in general and several specific settings.

Relationship between duration of preoperative symptoms and postoperative ileus for small bowel obstruction.

BACKGROUND: Factors associated with postoperative ileus and increased resource utilization for patients who undergo operative intervention for small-bowel obstruction are not extensively studied. We evaluated the association between total duration of preoperative symptoms and postoperative outcomes in this population. MATERIALS AND METHODS: We performed a retrospective review of patients who underwent surgery for small-bowel obstruction (2013-2016). Clinical data were recorded. Total duration of preoperative symptoms included all symptoms before operation, including those before presentation. Primary endpoint was time to tolerance of diet. Secondary endpoints included length of stay, total parenteral nutrition use, and intensive care unit admission. Association between variables and outcomes was analyzed using univariable analysis, multivariable Poisson modeling, and t-test to compare groups. RESULTS: Sixty-seven patients were included. On presentation, the median duration of symptoms before hospitalization was 2 d (range 0-18 d). Total duration of preoperative symptoms was associated with time to tolerance of diet on univariable analysis (Pearson's moment correlation: 0.28, 95% confidence interval: 0.028-0.5, P = 0.03). On multivariable analysis, ascites was correlated with time to tolerance of diet (P < 0.01), but total duration of preoperative symptoms (P = 0.07) was not. Length of stay (Pearson's correlation: 0.24, 95% confidence interval: -0.02 to 0.47, P = 0.07) was not statistically different in patients with longer preoperative symptoms. Symptom duration was not statistically associated with intensive care unit (P = 0.18) or total parenteral nutrition (P = 0.3) utilization. CONCLUSIONS: Our findings demonstrate that preoperative ascites correlated with increased time to tolerance of diet, and duration of preoperative symptoms may be related to postoperative ileus.

Postoperative delirium is associated with increased intensive care unit and hospital length of stays after liver transplantation.

BACKGROUND: Delirium is increasingly recognized as a common and important postoperative complication that significantly hinders surgical recovery. However, there is a paucity of data examining the incidence and impact of delirium after liver transplantation. METHODS: Retrospective case series in a tertiary care center examining all (n = 144) adult patients who underwent liver transplantation during a 6-y period. RESULTS: Delirium occurred in 25% of the patients with an average duration of 4.56 d. Patients who developed delirium were older (P = 0.007), had higher preoperative model for end-stage liver disease score (P = 0.019) and longer pretransplant hospital length of stay (LOS; P = 0.003). Patients with delirium were also more likely to have alcohol ingestion as an etiology of the liver failure (P = 0.033). Delirious patients had a trend toward increased ventilator days (P = 0.235) and significantly longer postoperative hospital (P = 0.001) and intensive care unit LOS (P = 0.001). Delirium was also associated with an increased frequency of hospital acquired infections including urinary tract infections (P = 0.005) and pneumonias (P = 0.001). CONCLUSIONS: Delirium is a common occurrence among liver transplant patients associated with increased complications and LOSs. Further prospective studies are needed to determine the specific risk factors in this complex population and to determine if delirium has an impact on long-term outcomes.

Uncertainty Among Acute Care Surgery Providers Does Not Change with Experience.

BACKGROUND: Acute care surgery (ACS) is a demanding profession that is by its na- ture unpredictable and requires practitioners to routinely deal with uncertainty and stress. We hy- pothesized that the field attracts people who are comfortable working in such an environment and that their comfort with uncertainty increases with experience. A surgeon's stress with uncertainty can be assessed usingthe previouslyvalidated Physician Reaction to Uncertainty Scale (PRU scale). METHODS: After approval from our IRB and the Eastern Association for the Surgery of Trauma (EAST) Research and Scholarship Committee, an online-survey was sent to EAST members. The survey included demographic questions and the PRU scale. 'The PRU scale requires answering 15 questions on a scale of one to six (strongly disagree to strongly agree) with four subsections measuring anxiety to uncertainty, concern about outcomes, reluctance to disclose uncertainty to patients, and reluctance to disclose mistakes to physicians. A higher score represents greater discomfort. Survey requests were sent to 1707 members; 424 surveys were complete and used for analysis. RESULTS: Most respondents were surgeons (92.4%) and male (77.1%). Average total score was 40.4/90. Overall discomfort with uncertainty on the PRU scale did not vary with gender (p = .88), experience (P=.11), age (P=.21), or practice location (P=.26). With increased experience, there was decreased re- luctance to disclose uncertaintyto patients (P = .03) and a trend to decreased anxiety about outcomes (P=.09). CONCLUSION: Overall discomfort with uncertainty among ACS providers appears to be inherent in their personality and does not change over a career span.'Ihis factor may play a role in the development of occupational stress since discomfort with uncer- tainty appears to persist over time. Future studies looking at other surgical specialties for comparison and atlongitudinal studies may provide insight into the personality of the community.

To close or not to close? Wound management in emergent colorectal surgery, an EAST multicenter prospective cohort study.

BACKGROUND: This study aimed to determine the clinical impact of wound management technique on surgical site infection (SSI), hospital length of stay (LOS), and mortality in emergent colorectal surgery. METHODS: A prospective observational study (2021-2023) of urgent or emergent colorectal surgery patients at 15 institutions was conducted. Pediatric patients and traumatic colorectal injuries were excluded. Patients were classified by wound closure technique: skin closed (SC), skin loosely closed (SLC), or skin open (SO). Primary outcomes were SSI, hospital LOS, and in-hospital mortality rates. Multivariable regression was used to assess the effect of wound closure on outcomes after controlling for demographics, patient characteristics, intensive care unit admission, vasopressor use, procedure details, and wound class. A priori power analysis indicated that 138 patients per group were required to detect a 10% difference in mortality rates. RESULTS: In total, 557 patients were included (SC, n = 262; SLC, n = 124; SO, n = 171). Statistically significant differences in body mass index, race/ethnicity, American Society of Anesthesiologist scores, EBL, intensive care unit admission, vasopressor therapy, procedure details, and wound class were observed across groups. Overall, average LOS was 16.9 ± 16.4 days, and rates of in-hospital mortality and SSI were 7.9% and 18.5%, respectively, with the lowest rates observed in the SC group. After risk adjustment, SO was associated with increased risk of mortality (OR, 3.003; p = 0.028) in comparison with the SC group. Skin loosely closed was associated with increased risk of superficial SSI (OR, 3.439; p = 0.014), after risk adjustment. CONCLUSION: When compared with the SC group, the SO group was associated with mortality but comparable when considering all other outcomes, while the SLC was associated with increased superficial SSI. Complete skin closure may be a viable wound management technique in emergent colorectal surgery. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Effects of novel Coronavirus (COVID-19) on presentation, management, and outcomes of acute cholecystitis at an academic tertiary care center cholecystitis management during COVID-19.

Background: The COVID-19 pandemic necessitated adjustments to nearly all aspects of healthcare, including surgical care. The effects of these adjustments have not been well studied on acute surgical problems conventionally managed non-electively in large, tertiary care centers. Methods: A retrospective analysis of admitted patients with acute cholecystitis at a US academic tertiary care center was performed. We compared the presentation, management, and 30-day outcomes of patients admitted during a 2-month time period during early COVID, to a pre-COVID control group of admitted cholecystitis patients over a 2-month span. Results: The study cohort captured 24 patients, while the control cohort encompassed 53 patients. A non-significant trend toward non-operative management in the COVID cohort is reported. There was no delay in time-to-surgery or complication rate. No surgically managed patient developed COVID within 30 days of operation. Conclusions: Operative management of acute cholecystitis during the COVID-19 pandemic, with pre-operative testing and personal protective equipment guidelines, remained safe and effective.

Routine post-operative labs and healthcare system burden in acute appendicitis.

BACKGROUND: Data from the National Health Expenditure Accounts have shown a steady increase in healthcare cost paralleled by availability of laboratory tests. Resource utilization is a top priority for reducing health care costs. We hypothesized that routine post-operative laboratory utilization unnecessarily increases costs and healthcare system burden in acute appendicitis (AA) management. METHODS: A retrospective cohort of patients with uncomplicated AA 2016-2020 were identified. Clinical variables, demographics, lab usage, interventions, and costs were collected. RESULTS: A total of 3711 patients with uncomplicated AA were identified. Total costs of labs ($289,505, 99.56%) and repletions ($1287.63, 0.44%) were $290,792.63. Increased LOS was associated with lab utilization in multivariable modeling, increasing costs by $837,602 or 472.12 per patient. CONCLUSIONS: In our patient population, post-operative labs resulted in increased costs without discernible impact on clinical course. Routine post-operative laboratory testing should be re-evaluated in patients with minimal comorbidities as this likely increases cost without adding value.

Alcohol withdrawal syndrome in trauma patients: a study using the Trauma Quality Program Participant User File.

Objective: To identify the rates and possible predictors of alcohol withdrawal syndrome (AWS) among adult trauma patients. Methods: This is a retrospective review of all adult patients (18 years or older) included in the 2017 and 2018 American College of Surgeons Trauma Quality Program Participant User File (PUF). The main outcomes were rates and predictors of AWS. Results: 1 677 351 adult patients were included in the analysis. AWS was reported in 11 056 (0.7%). The rate increased to 0.9% in patients admitted for more than 2 days and 1.1% in those admitted for more than 3 days. Patients with AWS were more likely to be male (82.7% vs. 60.7%, p<0.001), have a history of alcohol use disorder (AUD) (70.3% vs. 5.6%, p<0.001) and have a positive blood alcohol concentration (BAC) on admission (68.2% vs. 28.6%, p<0.001). In a multivariable logistic regression, history of AUD (OR 12.9, 95% CI 12.1 to 13.7), cirrhosis (OR 2.1, 95% CI 1.9 to 2.3), positive toxicology screen for barbiturates (OR 2.1, 95% CI 1.6 to 2.7), tricyclic antidepressants (OR 2.2, 95% CI 1.5 to 3.1) or alcohol (OR 2.5, 95% CI 2.4 to 2.7), and Abbreviated Injury Scale head score of ≥3 (OR 1.7, 95% CI 1.6 to 1.8) were the strongest predictors for AWS. Conversely, only 2.7% of patients with a positive BAC on admission, 7.6% with a history of AUD and 4.9% with cirrhosis developed AWS. Conclusion: AWS after trauma was an uncommon occurrence in the patients in the PUF, even in higher-risk patient populations. Level of evidence: IV: retrospective study with more than one negative criterion.

Duration of antimicrobial treatment for complicated intra-abdominal infections after definitive source control: A systematic review, meta-analysis, and practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: Recent studies have evaluated outcomes associated with duration of antimicrobial treatment for complicated intra-abdominal infections (cIAI). The goal of this guideline was to help clinicians better define appropriate antimicrobial duration in patients who have undergone definitive source control for cIAI. METHODS: A working group of Eastern Association for the Surgery of Trauma (EAST) performed a systematic review and meta-analyses of the available data pertaining to the duration of antibiotics after definitive source control of cIAI in adult patients. Only studies that compared patients treated with short vs. long duration antibiotic regimens were included. The critical outcomes of interest were selected by the group. Noninferiority of short compared with long duration of antimicrobial treatment was defined as an indicator for a potential recommendation in favor of shorter antibiotics course. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to assess the quality of the evidence and to formulate recommendations. RESULTS: Sixteen studies were included. The short duration ranged from 1 dose to ≤10 days, with an average of 4 days, and the long duration ranged >1 day to 28 days, with an average of 8 days. There were no differences between short and long duration of antibiotics in terms of mortality (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.56-1.44), rate of surgical site infection (OR, 0.88; 95% CI, 0.56-1.38); persistent/recurrent abscess (OR, 0.76; 95% CI, 0.45-1.29); unplanned interventions (OR, 0.53; 95% CI, 0.12-2.26); hospital length of stay (mean difference, -2.62 days; CI, -7.08 to 1.83 days); or readmissions (OR, 0.92; 95% CI, 0.50-1.69). The level of evidence was assessed as very low. CONCLUSION: The group made a recommendation for shorter (four or less days) versus longer duration (eight or more days) of antimicrobial treatment in adult patients with cIAIs who had definitive source control. LEVEL OF EVIDENCE: Systematic Review and Meta-Analysis; Level III.

Improved outcomes using laparoscopy for emergency colectomy after mitigating bias by negative control exposure analysis.

BACKGROUND: Laparoscopy is superior to open surgery for elective colectomy, but its role in emergency colectomy remains unclear. Previous studies were small and limited by confounding because surgeons may have selected lower-risk patients for laparoscopy. We therefore studied the effect of attempting laparoscopy for emergency colectomies while adjusting for confounding using multiple techniques in a large, nationwide registry. METHODS: Using National Surgical Quality Improvement Program data, we identified emergency colectomy cases from 2014 to 2018. We first compared outcomes between patients who underwent laparoscopic versus open surgery, while adjusting for baseline variables using both propensity scores and regression. Next, we performed a negative control exposure analysis. By assuming that the group that converted to open did not benefit from the attempt at laparoscopy, we used the observed benefit to bound the effect of unmeasured confounding. RESULTS: Of 21,453 patients meeting criteria, 3,867 underwent laparoscopy, of which 1,375 converted to open. In both inverse probability of treatment weighting and regression analyses, attempting laparoscopy was associated with improved 30-day mortality, overall morbidity, anastomotic leak, surgical site infection, postoperative septic shock, and length of hospital stay compared with open surgery. These effects were consistent with the lower bounds computed from the converted group. CONCLUSION: Laparoscopic surgery for colorectal emergencies appears to improve outcomes compared with open surgery. The benefit is observed even after adjusting for both measured and unmeasured confounding using multiple statistical approaches, thus suggesting a benefit not attributable to patient selection.

Academic Medical Centers Experienced Higher Rates of Post-Operative Health-Care-Associated Infections during the COVID-19 Pandemic: A Post Hoc Analysis of an Eastern Association for the Surgery of Trauma Multicenter Trial.

Background: We sought to examine health-care-associated infections (HAIs) among patients undergoing an appendectomy at academic medical centers (AMCs) and non-AMCs during the coronavirus disease 2019 (COVID-19) peri-pandemic. We hypothesized that AMCs would have higher rates of post-operative HAIs during the first wave of the pandemic. Patients and Methods: We performed a post hoc analysis of a prospective, observational, multi-center study of patients aged >18 years who underwent an appendectomy for acute appendicitis before (pre-CoV), during (CoV), and after pandemic restrictions were lifted (post-CoV). Patients were grouped according to hospital type (AMC vs. non-AMC). Our primary outcome was the incidence of post-operative HAIs. Results: There were 1,003 patients; 69.5% (n = 697) were treated at AMCs and 30.5% (n = 306) at non-AMCs. Patients at AMCs had greater rates of concomitant COVID-19 infections (5.5% vs. 0.7%; p < 0.0001) and worse operative appendicitis severity (p = 0.01). Greater rates of HAIs were seen at AMCs compared with non-AMCs (4.9% vs. 2%; p = 0.03). Surgical site infections were the most common HAI and occurred more often at AMCs (4.3% vs. 1.6%; p = 0.04). Only during CoV were there more HAIs at AMCs (5.1% vs. 0.3%; p = 0.02). Undergoing surgery at an AMC during CoV was a risk factor for HAIs (adjusted odds ratio [aOR], 8.55; 95% confidence interval [CI], 1.03-71.03; p = 0.04). Conclusions: During the COVID-19 pandemic, appendectomies performed at AMCs were an independent risk factor for post-operative HAIs. Our findings stress the importance of adherence to standard infection prevention efforts during future healthcare crises.

Association of Acute Care Surgeon Experience With Emergency Surgery Patient Outcomes and Mortality.

Importance: Previous studies comparing emergency surgery outcomes with surgeon experience have been small or used administrative databases without controlling for patient physiology or operative complexity. Objective: To evaluate the association of acute care surgeon experience with patient morbidity and mortality after emergency surgical procedures. Design, Setting, and Participants: This cohort study evaluated the association of surgeon experience with emergency surgery outcomes at 5 US academic level 1 trauma centers where the same surgeons provided emergency general surgical care. A total of 772 patients who presented with a traumatic injury and required an emergency surgical procedure or who presented with or developed a condition requiring an emergency general surgical intervention were operated on by 1 of 56 acute care surgeons. Surgeon groups were divided by experience of less than 6 years (early career), 6 to 10 years (early midcareer), 11 to 30 years (late midcareer), and 30 years or more (late career) from the end of training. Surgeons with less than 3 years of experience were also compared with the entire cohort. Hierarchical logistic regression models were constructed controlling for Emergency Surgery Score, case complexity, preoperative transfusion, and trauma or emergency general surgery. Data were collected from May 2015 to July 2017 and analyzed from February to May 2020. Main Outcomes and Measures: Mortality, complications, length of stay, blood loss, and unplanned return to the operating room. Results: Of 772 included patients, 469 (60.8%) were male, and the mean (SD) age was 50.1 (20.0) years. Of 772 operations, 618 were by surgeons with less than 10 years of experience. Early- and late-midcareer surgeons generally operated on older patients and patients with more septic shock, acute kidney failure, and higher Emergency Surgery Scores. Patient mortality, complications, postoperative transfusion, organ-space surgical site infection, and length of stay were similar between surgeon groups. Patients operated on by early-career surgeons had higher rates of unplanned return to the operating room compared with those operated on by early-midcareer surgeons (odds ratio [OR], 0.66; 95% CI, 0.40-1.09), late-midcareer surgeons (OR, 0.34; 95% CI, 0.13-0.90), and late-career surgeons (OR, 1.11; 95% CI, 0.45-2.75). Patients operated on by surgeons with less than 3 years of experience had similar mortality compared with the rest of the cohort (OR, 1.97; 95% CI, 0.85-4.57) but higher rates of complications (OR, 2.07; 95% CI, 1.05-4.07). Conclusions and Relevance: In this study, experienced surgeons generally operated on older patients with more septic shock and kidney failure without affecting risk-adjusted mortality. Increased complications and unplanned return to the operating room may improve with experience. Early-career surgeons' outcomes may be improved if they are supported while experience is garnered.

Increased mortality with resuscitative endovascular balloon occlusion of the aorta only mitigated by strong unmeasured confounding: An expanded analysis using the National Trauma Data Bank.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is being increasingly adopted to manage noncompressible torso hemorrhage, but a recent analysis of the 2015 to 2016 Trauma Quality Improvement Project (TQIP) data set showed that placement of REBOA was associated with higher rates of death, lower extremity amputation, and acute kidney injury (AKI). We expand this analysis by including the 2017 data set, quantifying the potential role of residual confounding, and distinguishing between traumatic and ischemic lower extremity amputation. METHODS: This retrospective study used the 2015 to 2017 TQIP database and included patients older than 18 years, with signs of life on arrival, who had no aortic injury and were not transferred. Resuscitative endovascular balloon occlusions of the aorta placed after 2 hours were excluded. We adjusted for baseline variables using propensity scores with inverse probability of treatment weighting. A sensitivity analysis was then conducted to determine the strength of an unmeasured confounder (e.g., unmeasured shock severity/response to resuscitation) that could explain the effect on mortality. Finally, lower extremity injury patterns of patients undergoing REBOA were inspected to distinguish amputation indicated for traumatic injury from complications of REBOA placement. RESULTS: Of 1,392,482 patients meeting the inclusion criteria, 187 underwent REBOA. After inverse probability of treatment weighting, all covariates were balanced. The risk difference for mortality was 0.21 (0.14-0.29) and for AKI was 0.041 (-0.007 to 0.089). For the mortality effect to be explained by an unmeasured confounder, it would need to be stronger than any observed in terms of its relationship with mortality and with REBOA placement. Eleven REBOA patients underwent lower extremity amputation; however, they all suffered severe traumatic injury to the lower extremity. CONCLUSION: There is no evidence in the TQIP data set to suggest that REBOA causes amputation, and the evidence for its effect on AKI is considerably weaker than previously reported. The increased mortality effect of REBOA is confirmed and could only be nullified by a potent confounder. LEVEL OF EVIDENCE: Therapeutic/care management, level IV.

Contemporary management of spontaneous retroperitoneal and rectus sheath hematomas.

BACKGROUND: Retroperitoneal and rectus sheath hematomas can occur spontaneously. There is a lack of research about the disease progression, optimal treatment strategies and the need for surgical intervention. Our study investigated their outcomes and management. STUDY DESIGN: Adult patients admitted during a one-year period with non-traumatic retroperitoneal or rectus sheath hematomas were retrospectively identified. Biographical, hospital-course, and outcome data were extracted. RESULTS: 99 patients were included; median age was 73-years (IQR 61-80). 88 patients were on an anticoagulant or antiplatelet agent. Warfarin and intravenous heparin being the most commonly utilized agents (42% and 36.4%, respectively). All 99 patients were diagnosed by CT scan. 79 patients received some sort of blood product (79.8% PRBC, 43.4% FFP, 17% platelets), and 26 patients were in hemorrhagic shock. 17 patients underwent angiography and/or angioembolization. Neither anticoagulation in general nor any specific agent was associated with the need for blood product transfusion or angiography. 13 patients died but none were attributable to the hematoma. CONCLUSION: Both hematomas are usually self-limiting and rarely require surgical intervention. A subset may require angioembolization.

The effect of anticoagulation on outcomes after liver and spleen injuries: A research consortium of New England centers for trauma (ReCONECT) study.

BACKGROUND: Liver and spleen injuries are the most commonly injured solid organs, the effects of anticoagulation on these injuries has not yet been well characterized. STUDY DESIGN: Multicenter retrospective study. RESULT: During the 4-year study period, 1254 patients, 64 (5%) on anticoagulation (AC), were admitted with liver and/or splenic injury. 58% of patients had a splenic injury, 53% had a liver injury and 11% had both. Patients on AC were older than non-AC patients (mean age 60.9 vs. 38.6 years, p < 0.001). The most common AC drug was warfarin (70%) with atrial fibrillation (47%) the most common indication for AC. There was no significant difference in AAST injury grade between AC and non-AC patients (median grade 2), but AC patients required a blood product transfusion more commonly (58 vs 40%, p = 0.007) particularly FFP (4 vs 19%, p < 0.01). Among those transfused, non-AC patients required slightly more PRBC (5.7 vs 3.8 units, p = 0.018) but similar amount of FFP (3.2 vs 3.1 units, p = 0.92). The two groups had no significant difference in the rates of initial non-operative management (50% (AC) vs 56% (non-AC), p = 0.3)) or failure of non-operative management (7 vs 4%, p = 0.16). AC patients were more likely to be managed initially with angiography (36 vs 20%, p = 0.001) while non-AC patients with surgery (24% vs 13%, p = 0.04). There was no significant difference in LOS and mortality. CONCLUSION: The use of anticoagulation did not result in a difference in outcomes among patients with spleen and/or liver injuries.

Antimotility agents for the treatment of acute noninfectious diarrhea in critically ill patients: A practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: Acute noninfectious diarrhea is a common phenomenon in intensive care unit patients. Multiple treatments are suggested but the most effective management is unknown. A working group of the Eastern Association for the Surgery of Trauma, aimed to evaluate the effectiveness of loperamide, diphenoxylate/atropine, and elemental diet on acute noninfectious diarrhea in critically ill adults and to develop recommendations applicable to daily clinical practice. METHODS: The literature search identified 11 randomized controlled trials (RCT) appropriate for inclusion. The Grading of Recommendations Assessment, Development, and Evaluation methodology was applied to evaluate the effect of loperamide, diphenoxylate/atropine, and elemental diet on the resolution of noninfectious diarrhea in critically ill adults based on selected outcomes: improvement in clinical diarrhea, fecal frequency, time to the diarrhea resolution, and hospital length of stay. RESULTS: The level of evidence was assessed as very low. Analyses of 10 RCTs showed that loperamide facilitates resolution of diarrhea. Diphenoxylate/atropine was evaluated in three RCTs and was as effective as loperamide and more effective than placebo. No studies evaluating elemental diet as an intervention in patients with diarrhea were found. CONCLUSION: Loperamide and diphenoxylate/atropine are conditionally recommended to be used in critically ill patients with acute noninfectious diarrhea. LEVEL OF EVIDENCE: Systematic Review/Guidelines, level III.

Evaluation of Swallow Function Post-Extubation: Is It Necessary to Wait 24 Hours?

BACKGROUND: Post-extubation dysphagia is associated with an increased incidence of nosocomial pneumonias, longer hospitalizations, and higher re-intubation rates. The purpose of this study was to determine if it is necessary to delay swallow evaluation for 24 hours post-extubation. METHODS: A prospective investigation of swallowing was conducted at 1, 4, and 24 hours post-extubation to determine if it is necessary to delay swallow evaluation following intubation. Participants were 202 adults from 5 different intensive care units (ICU). RESULTS: A total of 166 of 202 (82.2%) passed the Yale Swallow Protocol at 1 hour post-extubation, with an additional 11 (177/202; 87.6%) at 4 hours, and 8 more (185/202; 91.6%) at 24 hours. Only intubation duration ≥4 days was significantly associated with nonfunctional swallowing. CONCLUSIONS: We found it is not necessary to delay assessment of swallowing in individuals who are post-extubation. Specifically, the majority of patients in our study (82.2%) passed a swallow screening at 1 hour post-extubation.

Promotility agents for the treatment of ileus in adult surgical patients: A practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: Ileus is a common challenge in adult surgical patients with estimated incidence to be 17% to 80%. The main mechanisms of the postoperative ileus pathophysiology are fluid overload, exogenous opioids, neurohormonal dysfunction, gastrointestinal stretch, and inflammation. Management includes addressing the underlying cause and supportive care. Multiple medical interventions have been proposed, but effectiveness is uncertain. A working group of the Eastern Association for the Surgery of Trauma aimed to evaluate the effectiveness of metoclopramide, erythromycin, and early enteral nutrition (EEN) on ileus in adult surgical patients and to develop recommendations applicable in a daily clinical practice. METHODS: Literature search identified 45 articles appropriate for inclusion. The Grading of Recommendations Assessment, Development and Evaluation methodology was applied to evaluate the effect of metoclopramide, erythromycin, and EEN on the resolution of ileus in adult surgical patients based on selected outcomes: return of normal bowel function, attainment of enteral feeding goal, and hospital length of stay. The recommendations were made based on the results of a systematic review, a meta-analysis, and evaluation of levels of evidence. RESULTS: The level of evidence for all PICOs was assessed as low. Neither metoclopramide nor erythromycin were effective in expediting the resolution of ileus. Analyses of 32 randomized controlled trials showed that EEN facilitates return of normal bowel function, achieving enteral nutrition goals, and reducing hospital length of stay. CONCLUSION: In patients who have undergone abdominal surgery, we strongly recommend EEN to expedite resolution of Ileus, but we cannot recommend for or against the use of either metoclopramide or erythromycin to hasten the resolution of ileus in these patients.
