The MHPTS provides a brief, reliable, practical measure of CRM skills that can be used by participants in CRM training to reflect on and evaluate their performance as a team. Further evaluation of validity and appropriateness in other simulation and medical settings is desirable.

Patients with end-stage liver disease usually show a hyperdynamic circulatory state. It has previously been reported that patients who develop myocardial depression in the early post-liver transplantation period are more prone to organ failure and death. We reviewed the records of 754 adult patients undergoing liver transplantation at our institution and identified 7 patients who initially showed hyperdynamic circulation, but then developed reversible dilated cardiomyopathy in the early posttransplantation period. All identifiable causes of cardiac dysfunction, such as myocardial ischemia, thyroid dysfunction, and electrolyte imbalances, were excluded. Left ventricular ejection fraction decreased from a preoperative median baseline of 60% to 20% (P ‫؍‬ .02), with four-chamber dilatation on echocardiogram. All these patients required supportive care, including mechanical ventilation, afterload reduction, inotropic support, and monitoring in the intensive care unit. Cardiac function subsequently improved in all patients, with ejection fraction increasing to a median of 50%. All patients were discharged from the hospital. At a median follow-up of 15 months, there was no recurrence of heart failure. The increased peripheral resistance seen after successful liver transplantation may be an important causative factor. Copyright 1998 by the American Association for the Study of Liver Diseases H yperdynamic circulation has been repeatedly documented in patients with liver disease since the first description of the hyperdynamic circulatory state by Kowalski and Abelman in 1953. 1 Even those patients who were not previously hyperdynamic can respond to recirculation at the time of orthotopic liver transplantation (OLT) by developing a hyperdynamic circulatory state. 2 This hyperdynamic circulatory state usually resolves in the weeks after transplantation, 3,4 although it can sometimes persist even after successful liver transplantation. 5 We describe a small subset of post-OLT patients who showed an initial hyperdynamic circulatory state, followed by a period of markedly reduced cardiac function associated with cardiac dilatation and associated clinical heart failure. This document is the first to characterize this syndrome of reversible, dilated cardiomyopathy after OLT. Materials and MethodsWe reviewed a summary of the medical records of 754 adults (Ͼ18 years of age) undergoing OLT at the Mayo Clinic (Rochester, MN) from March 1985 through December 1996. The medical records of patients with chest radiograph evidence of pulmonary edema were carefully reviewed to identify a subset of patients with myocardial dysfunction, all of whom had echocardiographic evidence of a dilated cardiomyopathy post-OLT. We excluded patients with myocardial infarction at the time of congestive heart failure. Myocardial infarction was defined as elevation of cardiac enzyme levels with or without electrocardiographic changes. We also excluded patients who had intraoperative cardiac complications such as myocardial infarction, severe persistent hy...

Simulation training is rapidly becoming an integral element of the education curriculum of anesthesia residency programs. We report a case of successful resuscitation of bupivacaine-induced cardiac arrest treated with i.v. lipid emulsion by providers who had recently participated in simulation training involving a scenario nearly identical to this case. Upon debriefing, it was determined that the previous training influenced execution of the following steps: rapid problem recognition, prompt initiation of specific therapy in the setting of supportive advanced cardiac life support measures, and coordinated team efforts. Although the true cause of efficient resuscitation and ultimate recovery cannot be proven, the efficiency of the resuscitation process, including timely administration of lipid emulsion, is evidence that simulation may be useful for training providers to manage rare emergencies.

Internship Boot Camp is a unique learning environment that is recalled by participants as the most helpful, of all components of their medical school education, in preparation for internship.

Background We sought to determine whether mannequin-based simulation can reliably characterize how board-certified anesthesiologists manage simulated medical emergencies. Our primary focus was to identify gaps in performance and to establish psychometric properties of the assessment methods. Methods A total of 263 consenting board-certified anesthesiologists participating in existing simulation-based maintenance of certification courses at one of eight simulation centers were video recorded performing simulated emergency scenarios. Each participated in two 20-min, standardized, high-fidelity simulated medical crisis scenarios, once each as primary anesthesiologist and first responder. Via a Delphi technique, an independent panel of expert anesthesiologists identified critical performance elements for each scenario. Trained, blinded anesthesiologists rated video recordings using standardized rating tools. Measures included the percentage of critical performance elements observed and holistic (one to nine ordinal scale) ratings of participant’s technical and nontechnical performance. Raters also judged whether the performance was at a level expected of a board-certified anesthesiologist. Results Rater reliability for most measures was good. In 284 simulated emergencies, participants were rated as successfully completing 81% (interquartile range, 75 to 90%) of the critical performance elements. The median rating of both technical and nontechnical holistic performance was five, distributed across the nine-point scale. Approximately one-quarter of participants received low holistic ratings (i.e., three or less). Higher-rated performances were associated with younger age but not with previous simulation experience or other individual characteristics. Calling for help was associated with better individual and team performance. Conclusions Standardized simulation-based assessment identified performance gaps informing opportunities for improvement. If a substantial proportion of experienced anesthesiologists struggle with managing medical emergencies, continuing medical education activities should be reevaluated.

ObjectiveTo investigate whether the addition of liposomal bupivacaine abdominal wall blocks to a multimodal analgesic regimen improves postoperative numeric rating scale pain scores and reduces opioid consumption in patients undergoing living liver donation.Patients and MethodsWe conducted a single-center, retrospective review of patients who underwent living liver donation from January 1, 2011, through February 19, 2016, and received multimodal analgesia with (block group) or without (control group) abdominal wall blockade. The block solution consisted of liposomal bupivacaine (266 mg) mixed with 30 mL of 0.25% bupivacaine. Both groups received intrathecal hydromorphone. Main outcome measures were pain scores, opioid requirements, time to full diet, and bowel activity.ResultsPostoperative day 0 pain scores were significantly better in the block group (n=29) than in the control group (n=48) (2.4 vs 3.5; P=.002) but were not significantly different on subsequent days. Opioid requirements were significantly decreased for the block group in the postanesthesia care unit (0 vs 9 mg oral morphine equivalents; P=.002) and on postoperative day 0 (7 vs 18 mg oral morphine equivalents; P=.004). Median (interquartile range) time to full diet was 23 hours (14-30 hours) in the block group and 38 hours (24-53 hours) in the control group (P=.001); time to bowel activity was also shorter in the block group (45 hours [38-73 hours] vs 67 hours [51-77 hours]; P=.01).ConclusionAbdominal wall blockade with liposomal bupivacaine after donor hepatectomy provides an effective method of postoperative pain control and decreases time to full diet and bowel activity.
