The purpose of this study was to identify the population of pediatric patients who arrive without signs of life and describe outcomes using a national database. Patients eighteen and younger with no signs of life were pulled from the National Trauma Database (NTDB) from the years 2007-2016. A total of N = 7503 patients were separated into two cohorts for comparison. Subset analysis was also conducted for patients undergoing a thoracotomy. Statistical analysis was performed on the collected data. Over the 9-year period most patients died in the ED or hospital (95.7%), very few patients were discharged home (1.3%), and ED thoracotomies were performed rarely (9%) with most patients dying (97%). Arrival to the trauma bay without signs of life is associated with a dismal prognosis. Clinical judgment must be carefully applied to choose the small number of patients who would benefit from an aggressive approach.
Tension-free repairs have revolutionized the way we repair hernias. To help reduce undue tension when performing ventral hernia repair, multiple different techniques of myofascial releases have been described. The purpose of this project is to evaluate tension measurements for commonly performed myofascial releases in abdominal wall hernia repair. Patients undergoing myofascial release techniques for their ventral hernias were enrolled in a prospective Institutional Review Board-approved protocol to measure abdominal wall tension from June 1, 2011 to August 1, 2019. Abdominal wall tensions were measured using tensiometers before and after myofascial release techniques. Descriptive statistics were performed and data were analyzed. Thirty patients had tension measurements (5 anterior myofascial separation, 25 posterior myofascial separation with transversus abdominis release [TAR]). Average age was 60.1 years (range 29-81), 83% Caucasian, 53% female, and 42% recurrent hernias. The average hernia defect in patients undergoing anterior myofascial release was 117.3 cm2, and the average mesh size was 650 cm2. The reduction in tension after anterior release was 4.7 lbs (2.7 lbs vs 7.4 lbs). The average hernia defect in patients undergoing posterior myofascial release (TAR) was 183 cm2, and the average mesh size was 761.36 cm2. The reduction in tension after bilateral posterior rectus sheath incision was 2.55 lbs (5.01 lbs vs 7.56 lbs) with 0.66 lbs further reduction in tension after TAR (4.35 lbs vs 5.01). In this evaluation, abdominal wall tension measurements are shown to be a feasible adjunct during open hernia repair. Preliminary data show tension reductions associated with the different myofascial release techniques and, with further study, may be a useful intraoperative adjunct for decision making in hernia repair.
Purpose: Hernia prevention following abdominal surgery has become a subject of growing interest in general surgery. Prophylactic mesh augmentation (PMA) is an emerging technique to prevent incisional hernia in high-risk populations. The aim of this study was to determine the efficacy and safety of PMA using an absorbable mesh. Methods: A retrospective review was performed on patients who underwent PMA between July 2014 and March 2020. A prophylactic synthetic absorbable mesh (Phasix™; Becton Dickinson, Franklin Lakes, NJ) was placed at the surgeon’s discretion according to the indication for the primary operation. The primary outcome was the incisional hernia rate. Secondary outcomes included mesh-related or other complications. Results: Fifty patients underwent PMA following cystectomy with ileal conduit, open aortic surgery, or colostomy creation/takedown. Overall, 10 patients (20%) developed hernia at a median follow-up of 2.2 years. Six of these 10 hernias occurred at incisions where mesh was not placed. There were no documented mesh infections. One mesh (2%) in the AAA group was explanted due to an infected endograft, but there was no evidence of mesh complication. Two patients (4%) developed seroma. Two (4%) patients developed superficial surgical site infections (SSI). There were no documented deep-space SSI. Conclusion: PMA is an emerging technique with a low rate of incisional hernia in high-risk patients, such as those undergoing stoma creation or open aortic intervention. The use of an absorbable mesh seems promising, however more and longer-term research is needed.
Despite evidence that small bite closure is beneficial, it is not well documented how accurately and consistently surgeons employ this technique. We created a felt model to simulate fascial closure and educate residents regarding small bites. This study aims to gauge accuracy and consistency of bite size in fascial closure and assess if utilizing a templated model could improve technique. Two 10 cm incisions were made in different pieces of felt. Residents were instructed to suture the incisions to simulate fascial closure by running the incisions closed with 1 cm and 5 mm bites respectively. The process was repeated with templated pieces of felt marking 1 and 0.5 cm to guide bite size. Residents were timed for each closure. The travel and distance from the midline for each bite was measured and analysis performed. 14 residents participated. Paired T-test compared means and standard deviations of bite size. Taking 5 mm bites took more time. Standard deviation of travel and right sided distance from midline were significantly smaller when a template was utilized. Standard deviation of travel as well as right sided distance was also improved when instructed to take 5 mm bites. This study demonstrates that a small bite technique results more closure and that when residents are instructed to take smaller bites. The adage, “aim small, miss small,” holds true in fascial closure and may be one reason why small bites improve hernia rates. This study also suggests that the use of a template improves accuracy and consistency of closure regardless of bite size intention.
Introduction Long known to be a widespread source of injury, dog bites continue to occur and can frequently be devastating. There is lasting economic and personal hardship associated with this as many attacks can be severe, especially in children. This study describes the differences between dog bites and all other bites in the trauma patient population. Methods We included all patients from the National Trauma Data Bank (NTDB) from 2007 to 2016. All patients with an E-code for any type of bite were included. The following predictors were examined: year, age, gender, race, ethnicity, transfer, injury type, ED disposition, and ISS ≥15. Standard t-test for age, chi-squared test for all categorical variables. Wilcoxon test for non-normal quantitative variables. Statistical analyses were performed using R version 4.0.2 statistical software. “Under resourced” will be defined as Self-Pay and Medicaid. “Not known” is removed and replaced with NAs. All other insurance types are included in “Normal”. Results All variables tested as significant. All variables analyzed tested as significantly different between dog bites and other animal bites. When the group, pediatric subset, and adult subset are evaluated (Tables 1), pediatric patients are more likely to be dog bite patients if they are from an under resourced background (OR 1.3, p-value < 0.001). Distribution of bites are not significantly different from Low to Normal resource adult patients. Conclusions Dog bites continue to be a public health problem and are more likely to be severe or fatal than bites from other animals and humans. Better methods of injury prevention and education need to be established. Children from under resourced backgrounds are at an increased risk of suffering a dog bite and all physicians should screen for and educate patients and families about this risk.
The Gaboon viper ( Bitis gabonica) is an exotic snake native to sub-Saharan Africa. Gaboon viper venom is an extremely toxic hemotoxin, causing severe coagulopathy and local tissue necrosis. These are not aggressive snakes and therefore bites involving humans are rare and there is not a substantial amount of literature documenting how to manage these injuries and resultant coagulopathies. We report a 29-year-old male presenting 3 hours after a Gaboon viper envenomation resulting in coagulopathy requiring massive resuscitation and multiple doses of antivenom. The patient received various blood products based on thromboelastography (TEG) and also underwent early continuous renal replacement therapy (CRRT) to assist in correction of severe acidosis and acute renal failure. The combination of TEG to guide resuscitation, administration of antivenom, and early implementation of CRRT allowed our team to correct venom-induced consumptive coagulopathy and ultimately allow the patient to survive following this extremely deadly Gaboon viper envenomation.
