Using Right-Sided Roll to Improve Reliability of Focused Assessment with Sonography in Trauma: An Eastern Association for the Surgery of Trauma Multicenter Prospective Study.

BACKGROUND: The Focused Assessment Sonography in Trauma (FAST) examination is the standard of care for detecting hemoperitoneum in hypotensive blunt trauma patients. A pilot study demonstrated earlier identification of intra-abdominal fluid via FAST after right-sided roll (FASTeR) when compared with the standard FAST. The purpose of this study was to evaluate this phenomenon prospectively in hypotensive blunt trauma patients. STUDY DESIGN: An Eastern Association for the Surgery of Trauma-approved multicenter prospective trial was performed June 2016 to October 2020 at 8 designated trauma centers. Hypotensive adult blunt trauma patients were included. A traditional FAST examination was performed. After this, the secondary survey logroll for back examination was standardized to the patient's right side. A repeat supine right upper quadrant ultrasound view was obtained. The presence or absence of hemoperitoneum was confirmed by CT scan or intraoperative findings. FAST and FASTeR were compared using receiver operating characteristics. The area under the curve was calculated. RESULTS: A total of 182 patients met inclusion criteria. A total of 65 patients (35.7%) had hemoperitoneum on CT scan or intraoperative findings. The sensitivity of FASTeR was 47.7%, and of FAST was 40.0% (p = 0.019). The receiver operating characteristics area under the curve of the FASTeR examination was 0.717 vs 0.687 for the FAST examination (p = 0.091). CONCLUSIONS: Addition of a right upper quadrant view after right-sided roll does improve the sensitivity of the FAST examination while maintaining the standard positive predictive value. We demonstrate a trend that does not reach statistical significance about the overall accuracy. This multicenter prospective trial was underpowered to reveal a statistically significant difference in the overall accuracy as measured by the receiver operating characteristics area under the curve.

Impact of Protocol Utilizing Water-Soluble Contrast for Adhesive Small Bowel Obstruction.

INTRODUCTION: Adhesive small bowel obstruction (ASBO) has classically been managed with nasogastric tube decompression and watchful waiting. Our group developed an evidence-based protocol to manage ASBO utilizing a water-soluble contrast (WSC) agent. We hypothesized the protocol would decrease the length of stay (LOS) for patients admitted with ASBO along with the time interval from admission to surgery. METHOD: From 2010 to 2018, a retrospective review was performed, including all patients admitted with a diagnosis of ASBO. These patients were divided into two groups: the preprotocol group included years 2010-2013 and the postprotocol group included years 2015-2018. A Student t-test and a two-proportion z-test were used for statistical analysis. RESULT: We captured 767 patients; 296 in the preprotocol group and 471 in the postprotocol group. We found a significant decrease in overall LOS between the preprotocol and postprotocol groups (6.56 d versus 4.08 d; P < 0.001) along with decreases in LOS for patients managed nonoperatively (5.36 d versus 3.42 d; P < 0.001) and operatively (16.09 d versus 9.47 d; P < 0.001). Time interval from admission to the operation was significantly decreased in the postprotocol group (3.79 d versus 2.10 d; P < 0.050). We identified a trend toward decreased rates of bowel ischemia and resections with our protocol. CONCLUSIONS: These results reaffirm previous reports of WSC's impact on overall LOS in ASBO while showing a similar impact on both operative and nonoperative groups. The decreased time interval between admission and operation may impact the incidence of bowel ischemia and resections.

Closing Contaminated Fascial Defects With Synthetic Mesh and a Vacuum-Assisted Closure Device.

BACKGROUND: The use of synthetic mesh is considered too high risk, and therefore, not an option when closing a contaminated abdominal fascial defect. This study evaluated the clinical outcomes when using synthetic mesh combined with vacuum-assisted closure (VAC) dressing to close these facial defects. MATERIALS AND METHODS: From 2010 to 2016, a retrospective review was performed, including 34 patients in a single rural trauma center who underwent a damage control laparotomy in the presence of a contaminated or infected field. Definitive abdominal closure with a bridging polypropylene mesh along with the application of a VAC dressing was done in all cases. Data collection included baseline demographics, operative indication, postoperative complications, mortality and length of follow up. RESULTS: Median age of the patients was 67 y (IQR 40-87 y), with 22 (65%) being male at the time of operation. The median duration of clinical follow-up was 15.15 mo. The observed complications included three fistulas, two hernias, nine draining sinus tracts, and three mesh explanations with an overall complication rate of 41.1%. Although the absolute observed fistula rate was 8.8% (3 cases), the adjusted mesh-related fistulas formation rate after chart review was 0.0%. No mortalities were attributed directly to mesh-related complication. CONCLUSIONS: This study found no mesh-related fistulas when using a synthetic mesh along with a VAC dressing for abdominal closure in a contaminated field. These results may provide a platform for further study regarding the safety of this technique.

A novel protocol to maintain continuous access to thawed plasma at a rural trauma center.

BACKGROUND: Early administration of plasma improves mortality in massively transfused patients, but the thawing process causes delay. Small rural centers have been reluctant to maintain thawed plasma due to waste concerns. Our 254-bed rural Level II trauma center initiated a protocol allowing continuous access to thawed plasma, and we hypothesized its implementation would not increase waste or cost. METHODS: Two units of thawed plasma are continuously maintained in the trauma bay blood refrigerator. After 3 days, these units are replaced with freshly thawed plasma and returned to the blood bank for utilization prior to their 5-day expiration date. The blood bank monitors and rotates the plasma. Only trauma surgeons can use the plasma stored in the trauma bay. Wasted units and cost were measured over a 12-month period and compared with the previous 2 years. RESULTS: The blood bank thawed 1127 units of plasma during the study period assigning 274 to the trauma bay. When compared with previous years, we found a significant increase in waste (p < 0.001) and cost (p = 0.020) after implementing our protocol. It cost approximately US $125/month extra to maintain continuous access to thawed plasma during the study period. DISCUSSION: A protocol to maintain thawed plasma in the trauma bay at a rural Level II trauma center resulted in a miniscule increase in waste and cost when considering the scope of maintaining a trauma center. We think this cost is also minimal when compared with the value of having immediate access to thawed plasma. Constant availability of thawed plasma can be offered at smaller rural centers without a meaningful impact on cost. LEVEL OF EVIDENCE: Economic and Value-based Evaluations, Level III.
