The impact of standardized protocol implementation for surgical damage control and temporary abdominal closure after emergent laparotomy.

ABSTRACT: BACKGROUND:To standardize care and promote early fascial closure among patients undergoing emergent laparotomy and temporary abdominal closure (TAC), we developed a protocol addressing patient selection, operative technique, resuscitation strategies, and critical care provisions. We hypothesized that primary fascial closure rates would increase following protocol implementation with no difference in complication rates. STUDY DESIGN:We performed a retrospective cohort analysis of 138 adult trauma and emergency general surgery patients who underwent emergent laparotomy and TAC, comparing protocol patients (n = 60) to recent historic controls (n = 78) who would have met protocol inclusion criteria. The protocol includes low-volume 3% hypertonic saline resuscitation, judicious wound vacuum fluid replacement, and early relaparotomy with sequential fascial closure. Demographics, baseline characteristics, illness severity, resuscitation course, operative management, and outcomes were compared. The primary outcome was fascial closure. RESULTS:Baseline characteristics, including age, American Society of Anesthesiologists class, and postoperative lactate levels, were similar between groups. Within 48 hours of initial laparotomy and TAC, protocol patients received significantly lower total intravenous fluid resuscitation volumes (9.7 vs. 11.4 L, p = 0.044) and exhibited higher serum osmolarity (303 vs. 293 mOsm/kg, p = 0.001). The interval between abdominal operations was significantly shorter following protocol implementation (28.2 vs. 32.2 hours, p = 0.027). The incidence of primary fascial closure was significantly higher in the protocol group (93% vs. 81%, p = 0.045, number needed to treat = 8.3). Complication rates were similar between groups. CONCLUSIONS:Protocol implementation was associated with lower crystalloid resuscitation volumes, a transient hyperosmolar state, shorter intervals between operations, and higher fascial closure rates with no difference in complications. LEVEL OF EVIDENCE:Therapeutic study, level IV.

Project description:BackgroundOur objective was to establish the safety of 3% hypertonic saline (HTS) resuscitation for trauma and acute care surgery patients undergoing emergent laparotomy and temporary abdominal closure (TAC) with the hypothesis that HTS administration would be associated with hyperosmolar hypercholoremic acidosis, lower resuscitation volumes, and higher fascial closure rates, without adversely affecting renal function.MethodsWe performed a retrospective cohort analysis of 189 trauma and acute care surgery patients who underwent emergent laparotomy and TAC, comparing patients with normal baseline renal function who received 3% HTS at 30 mL/h (n = 36) to patients with standard resuscitation (n = 153) by baseline characteristics, resuscitation parameters, and outcomes including primary fascial closure and Kidney Disease: Improving Global Outcomes stages of acute kidney injury.ResultsThe HTS and standard resuscitation groups had similar baseline illness severity and organ dysfunction, though HTS patients had lower serum creatinine at initial laparotomy (1.2 mg/dL vs. 1.4 mg/dL; p = 0.078). Forty-eight hours after TAC, HTS patients had significantly higher serum sodium (145.8 mEq/L vs. 142.2 mEq/L, p < 0.001), chloride (111.8 mEq/L vs. 106.6 mEq/L, p < 0.001), and osmolarity (305.8 mOsm/kg vs. 299.4 mOsm/kg; p = 0.006), and significantly lower arterial pH (7.34 vs. 7.38; p = 0.011). The HTS patients had lower intravenous fluid (IVF) volumes within 48 hours of TAC (8.5 L vs. 11.8 L; p = 0.004). Serum creatinine, urine output, and kidney injury were similar between groups. Fascial closure was achieved for 92% of all HTS patients and 77% of all standard resuscitation patients (p = 0.063). Considering all 189 patients, higher IVF resuscitation volumes within 48 hours of TAC were associated with decreased odds of fascial closure (odds ratio, 0.90; 95% confidence interval, 0.83-0.97; p = 0.003).ConclusionHypertonic saline resuscitation was associated with the development of a hypernatremic, hyperchloremic, hyperosmolar acidosis, and lower total IVF resuscitation volumes, without adversely affecting renal function. These findings may not be generalizable to patients with baseline renal dysfunction and susceptibility to hyperchloremic acidosis-induced kidney injury.Level of evidencePrognostic study, level II.

Project description:BackgroundThe purpose of this study was to characterize associations among serum proteins, negative-pressure wound therapy (NPWT) fluid loss, and primary fascial closure (PFC) following emergent laparotomy and temporary abdominal closure (TAC). We hypothesized that high levels of C-reactive protein (CRP) and NPWT output would be associated with hypoalbuminemia and failure to achieve PFC.MethodsWe performed a retrospective analysis of 233 patients managed with NPWT TAC. Serum proteins and resuscitation indices were assessed on admission, initial laparotomy, and then at 48 hours, 96 hours, 7 days, and discharge. Correlations were assessed by Pearson coefficient. Multivariable regression was performed to identify predictors of PFC with cutoff values for continuous variables determined by Youden index.ResultsPatients who failed to achieve PFC (n = 55) had significantly higher CRP at admission (249 vs. 148 mg/L, p = 0.003), initial laparotomy (237 vs. 154, p = 0.002), and discharge (124 vs. 72, p = 0.003), as well as significantly lower serum albumin at 7 days (2.3 vs. 2.5 g/dL, p = 0.028) and discharge (2.5 vs. 2.8, p = 0.004). Prealbumin (in milligrams per deciliter) was similar between groups at each time point. There was an inverse correlation between nadir serum albumin and total milliliters of NPWT output (r = -0.33, p < 0.001). Exogenous albumin administration (in grams per day) correlated with higher serum albumin levels at each time point: 48 hours: r = 0.26 (p = 0.002), 96 hours: r = 0.29 (p = 0.002), 7 days: r = 0.40 (p < 0.001). Albumin of less than 2.6 g/dL was an independent predictor of failure to achieve PFC (odds ratio, 2.59; 95% confidence interval, 1.02-6.61) in a multivariate model including abdominal sepsis, body mass index of greater than 40 kg/m, and CRP of greater than 250 mg/L.ConclusionsEarly and persistent systemic inflammation and high NPWT output were associated with hypoalbuminemia, which was an independent predictor of failure to achieve PFC. The utility of exogenous albumin following TAC requires further study.Level of evidencePrognostic study, level III; Therapeutic study, level IV.

Project description:BACKGROUND:Organ/space surgical site infection (OS-SSI) develops frequently after trauma laparotomies and is associated with significant morbidity. No valid model exists to accurately risk-stratify the probability of OS-SSI development after emergent laparotomy. Risk stratification for OS-SSI in these patients could guide promising, but unproven, interventions for OS-SSI prevention, such as more frequent dosing of intraoperative antibiotics or direct peritoneal resuscitation. We hypothesize that in trauma patients who undergo emergent laparotomy, probability of OS-SSI can be accurately estimated using patient data available during the index operation. METHODS:Retrospective review was performed on a prospectively maintained database of emergent trauma laparotomies from 2011 to 2016. Patient demographics and risk factors for OS-SSI were collected. We performed Bayesian multilevel logistic regression to develop the model based on a 70% training sample. Evaluation of model fit using area under the curve was performed on a 30% test sample. The Bayesian approach allowed the model to address clustering of patients within physician while implementing regularization to improve predictive performance on test data. RESULTS:One hundred seventy-two (15%) of 1,171 patients who underwent laparotomy developed OS-SSI. Variables thought to affect development of surgical site infections and were available to the surgeon near the conclusion of the trauma laparotomy were included in the model. Two variables that contributed most to OS-SSIs were damage-control laparotomy and colon resection. The area under the curve of the predictive model validated on the test sample was 0.78 (95% confidence interval, 0.71-0.85). CONCLUSION:Using a combination of factors available to surgeons before the end of an emergent laparotomy, the probability of OS-SSI could be accurately estimated using this retrospective cohort. A Web-based calculator is under design to allow the real-time estimation of probability of OS-SSI intraoperatively. Prospective validation of its generalizability to other trauma cohorts and of its utility at the point of care is required. LEVEL OF EVIDENCE:Prognostic study, level IV.

Project description:ObjectiveThe objective is to evaluate efficiency based on data on morbidity and mortality, health-related quality of life and healthcare-related costs after early reversal of temporary ileostomy after rectal resection for cancer compared with the standard procedure (late reversal).BackgroundReversal of a temporary ileostomy is generally associated with a low morbidity and mortality. However, ostomy reversal may cause complications requiring reoperation with subsequent major complications, in ranges from 0% to 7-9% and minor complications varying from 4-5% to 30%. Based on studies exploring and describing the time of closure in previous studies which are mostly of low quality, a recent review concluded that closing a temporary stoma within 2 weeks did not seem to be associated with an increase in morbidity and mortality.Design and methodsEarly closure of temporary ileostomy (EASY), a randomised controlled trial, is a prospective randomised controlled multicentre study which is performed within the framework of the Scandinavian Surgical Outcomes Research Group (http://www.ssorg.net/) and plans to include 200 patients from Danish and Swedish hospitals. The primary end-point of the study is the frequency of complications 0-12 months after surgery (the stoma creation operation). The secondary end-points of the study are (1) comparison of the total costs of the two groups at 6 and 12 months after surgery (stoma creation); (2) comparison of health-related quality of life in the two groups evaluated with the 36-item short-form and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-CR29/CR30 at 3, 6 and 12 months after surgery (stoma creation); and (3) comparison of disease-specific quality of life in the two groups at 3, 6 and 12 months after surgery (stoma creation).DiscussionThe aim of the EASY trial is to evaluate the efficiency of early reversal of temporary ileostomy after surgery for rectal cancer versus late reversal. The EASY trial is expected to have a huge impact on patient safety as well as an improvement in patient-reported outcome. Clinical trials identifier NCT01287637.
