Article Abstract
Incidence of coronary heart disease deaths has been reported to be higher in low socioeconomic groups compared to affluent subjects. In addition, a higher mortality rate has been reported at centers doing fewer open heart surgeries. This article presents evidence in variance with these convictions. We report a single team's experience with coronary artery surgery on 76 low socioeconomic, predominantly black patients (84%) over a period of 8 years. The volume of open heart surgery per year was less than 20. The overall mortality rate of 5.3%, infection rate of 1.3%, and perioperative infarction rate of 7.9% are not significantly different from the reported experience of high-volume surgical centers on similar patients during the same period. Thus, it is possible to obtain comparable results of myocardial revascularization surgery in low-volume, socioeconomically disadvantaged, inner city minority populations.

High Cirrhosis Surgical Volume Centers have Reduced Postoperative Mortality in Patients with Cirrhosis Undergoing Major Surgery.
Am J Gastroenterol

Patients with cirrhosis have increased surgical risk and require care team expertise. We explored the association between center cirrhosis surgical volume and post-operative mortality in a large VA dataset. In this retrospective cohort study of 14,500 major surgeries in patients with cirrhosis, we found in adjusted analysis that high-volume centers (>16 surgeries in past year) had a 36% reduced hazard of post-operative mortality through 90 days versus low-volume centers (<9 surgeries in past year; hazard ratio 0.

Background: Ultrasound-guided maxillary nerve block (UGMNB) is applied in oral and maxillofacial surgery to improve perioperative analgesia, decrease the risk of postoperative nausea and vomiting, and enhance recovery. However, the optimum volume of ropivacaine used for UGMNB is undetermined. Thus, it was hypothesized that in patients undergoing double-jaw surgery, low- and high-volume ropivacaine reduces perioperative pain with similar efficacy.

Children's Hospital of Philadelphia, Philadelphia, Pennsylvania, USA.
Background: Considerable variability exists in the described clinical and radiographic indications for use, surgical techniques, postoperative management, and risk profile after trochleoplasty for the management of patellofemoral instability (PFI). In areas of clinical uncertainty, a cohesive summary of expert opinion and identification of areas of variation in current practice can be useful in guiding current practice and future research efforts.
Purpose: To assess the current indications for use, surgical techniques, postoperative rehabilitation practices, and observed complication profile for trochleoplasty in the management of PFI among surgeons who perform this procedure.

Is it possible for a low-volume surgeon to enhance their surgical skills without performing actual surgeries by utilizing virtual reality headsets and emerging technologies? It has been observed that the time spent by surgical assistants in the operating room decreased after the post-shift leave regulation. In the literature, the use of virtual reality simulations as a support tool in surgical training is recommended. Although the efficacy of virtual reality surgical simulations in surgeries such as arthroscopy and laparoscopy has been proven, there are limited studies on their effect in open surgeries.

Introduction: Sepsis is an uncontrolled systemic response to infection that leads to life-threatening organ dysfunction. The in-hospital mortality rate remains significantly high in septic shock patients with malignancies. This study investigates whether early and high-volume administration of sodium bicarbonate during continuous renal replacement therapy (CRRT) can reduce 28-day mortality, increase shock reversal rates, and shorten the duration of CRRT, mechanical ventilation, and intensive care unit (ICU) stays.
