The Flipped Classroom Approach in a Pediatric Anesthesiology Fellowship Curriculum.

Background The flipped classroom approach is well documented to enhance medical education outcomes. Additionally, both the need for online learning materials and the increased demand for medical professionals during the COVID-19 pandemic has made this approach more relevant. The pediatric anesthesiology fellowship curriculum at one institution transitioned from a traditional classroom model to a flipped classroom approach to optimize the educational experience and support learner well-being. Approach Utilizing the American Board of Anesthesiology (ABA) and Accreditation Council for Graduate Medical Education (ACGME) content outlines, a novel, comprehensive curriculum was developed focusing on core clinical material and board review with the goal of providing structured learning while alleviating the burden of completing board review independently to improve work-life balance and reduce the potential for burnout. Evaluation Graduates of the program from 2017 to 2021 evaluated the flipped classroom structure and its perceived impact on their educational outcomes, wellness, and career development via a one-time, voluntary survey. Results indicated improved participation rates and educational benefits with the flipped classroom structure compared to the traditional structure. Fellows preferred the flipped classroom approach to the traditional lecture approach (72.2% vs. 27%), and they preferred custom-made prework material to traditional textbooks and articles. Fellows benefited from having more time for personal activities and other scholarly work, as evidenced by open-ended responses. Implications The flipped classroom structure was perceived as beneficial by pediatric anesthesiology fellows because of increased educational engagement, alleviation of academic burden, and improved wellness due to more time for non-academic activities. Further study is needed to optimize and correlate the new curriculum with objective educational outcomes.

Outcomes in pediatric liver transplant recipients receiving bilateral continuous erector spinae plane blocks.

BACKGROUND: Regional anesthesia allows for opioid-sparing and enhanced recovery after many major surgeries. Erector spinae blockade, with reduced bleeding risk and the option for continuous infusion, offers an opportunity to promote this principle in pediatric liver transplant patients. Our goal was to evaluate pain scores, opioid use, and return of bowel function following continuous ESP blockade in pediatric liver transplant recipients. METHODS: This retrospective cohort study included extubated patients who received a liver transplant at St. Louis Children's Hospital from July 2016 to July 2021. The control group, which did not meet the criteria for ESP blockade and received standard analgesia regimens, was compared to the group receiving continuous ESP blockade. Measured outcomes included pain scores, opioid consumption through postoperative day two, date of first bowel movement, and length of stay in the ICU and the hospital. RESULTS: Patient demographics between control and ESP groups showed no significant differences. Pain scores between control and ESP groups also showed no significant differences. Intraoperative and postoperative opioid requirements, studied in oral morphine equivalents per kilogram (OME/kg), were significantly lower for patients with ESP blockade. Time to first bowel movement was also significantly earlier for the ESP group. No significant differences were found in length of ICU or hospital stay. There were no safety concerns or complications related to ESP blockade. CONCLUSIONS: Use of continuous ESP blockade resulted in reduced opioid consumption through postoperative day two and earlier return of bowel function.

Reducing perioperative red blood cell unit issue orders, returns, and waste using failure modes and effects analysis.

BACKGROUND: Surgical transfusion has an outsized impact on hospital-based transfusion services, leading to blood product waste and unnecessary costs. The objective of this study was to design and implement a streamlined, reliable process for perioperative blood issue ordering and delivery to reduce waste. STUDY DESIGN AND METHODS: To address the high rates of surgical blood issue requests and red blood cell (RBC) unit waste at a large academic medical center, a failure modes and effects analysis was used to systematically examine perioperative blood management practices. Based on identified failure modes (e.g., miscommunication, knowledge gaps), a multi-component action plan was devised involving process changes, education, electronic clinical decision support, audit, and feedback. Changes in RBC unit issue requests, returns, waste, labor, and cost were measured pre- and post-intervention. RESULTS: The number of perioperative RBC unit issue requests decreased from 358 per month (SD 24) pre-intervention to 282 per month (SD 16) post-intervention (p < .001), resulting in an estimated savings of 8.9 h per month in blood bank staff labor. The issue-to-transfusion ratio decreased from 2.7 to 2.1 (p < .001). Perioperative RBC unit waste decreased from 4.5% of units issued pre-intervention to 0.8% of units issued post-intervention (p < .001), saving an estimated $148,543 in RBC unit acquisition costs and $546,093 in overhead costs per year. DISCUSSION: Our intervention, designed based on a structured failure modes analysis, achieved sustained reductions in perioperative RBC unit issue orders, returns, and waste, with associated benefits for blood conservation and transfusion program costs.

Nicotine-free vapor inhalation produces behavioral disruptions and anxiety-like behaviors in mice: Effects of puff duration, session length, sex, and flavor.

Electronic-cigarette's (ECIGs) popularity has grown over the last decade and changed the way individuals administer nicotine. Preclinical research is imperative for understanding the addictive properties and health-risks associated with ECIG use; however, there is not a standard dosing regimen used across research laboratories. The main objective was to determine how vapor puff durations, administration session length, and flavored e-liquid alter general and mood-disorder related behaviors while providing a foundation of vapor administration parameters. Adult male and female C57BL/6 mice were exposed to several nicotine-free unflavored vapor puff durations (1, 3, 6, or 10 s) and vapor administration session lengths (10 and 30 min) then measured on the following assays: locomotor activity (LMA), tail suspension test (TST), and light-dark test. The effects of mecamylamine and the time-course of vapor-induced depression of LMA also were assessed. Additionally, mice were exposed to flavored (strawberry and adventurers tobacco blend) vapor inhalation and measured on locomotor activity, tail suspension test, and light-dark test. Following both 10 and 30 min vapor administration session, there was a puff duration-dependent decrease in distance traveled, time in center, and rearing. The vapor-induced depression of LMA was not mediated by nicotine or nicotinic acetylcholine receptor (nAChR) activation and lasted 60-90 min. The 10 s puff duration produced an anxiogenic-like effect in the light-dark test by decreasing the time spent in the light side. Vapor inhalation did not significantly alter TST behavior. No significant effects of sex or flavor were found. The anxiogenic-like effects of nicotine-free vapor inhalation are concerning as many adolescents vape nicotine-free flavored e-liquid, and there is an association between ECIGs and mood disorders. Additionally, these studies demonstrate that vapor puff duration, but not vapor administration session length, is an important variable to consider during research design as it can become a confounding variable and alter baseline behaviors.
