RESUMEN
PURPOSE OF REVIEW: 5-Aminolevulinic acid hydrochloride (5-ALA), available under the trade name Gleolan, is an orally administered fluorophore drug used to enhance visual differentiation of cancerous tissue from healthy tissue, primarily during surgical resection of high-grade gliomas. Although given preoperatively, 5-ALA has important implications for anesthetic care throughout the perioperative period. This article reviews pharmacology, safety concerns, and perioperative considerations for patients who receive oral 5-ALA. RECENT FINDINGS: Although approved for clinical use by the United States Food and Drug Administration in 2017, studies and case reports published since then have further delineated side effects of this medication and its mechanisms and pharmacokinetics. SUMMARY: Mitigating the possible side effects of 5-ALA requires an understanding of its basic mechanism as well as focused perioperative planning and communication. Administration of this medication may result in nausea and vomiting, photosensitivity, increases in serum concentration of liver enzymes, and hypotension. Patients who receive 5-ALA must be protected from prolonged light exposure during the first 48âh after consumption and administration of other photosensitizing agents should be avoided (Supplemental Video File/Video abstract).
RESUMEN
Background: High-stakes yet clinically infrequent procedures are challenging to teach. Escape rooms may offer an innovative solution through game-based learning. There is limited guidance on how to design an escape room focused on physical puzzles. We designed and implemented a procedure-focused escape room to teach high-stakes procedures to anesthesiology residents. Methods: We selected 5 procedural skills relevant to anesthesiology residents through a modified Delphi technique: fiberoptic intubation, rapid infuser setup, intraosseous line placement, flexible bronchoscopy, and supraglottic airway exchange. We designed associated skills stations and linked them in sequence using an elaborate series of puzzles, locks, keys, and codes. The total cost of puzzle equipment was $169.53. After pilot testing, we implemented the escape room from July to November 2022. We assessed residents using a single group pretest-posttest study design. Results: Forty-three of 55 (78%) eligible anesthesiology residents participated in the escape room. Thirty-one residents completed the surveys. Resident self-efficacy significantly improved for each of the 5 procedures. Twenty-six of 27 (96%) residents preferred the escape room over a typical procedural skills workshop. Conclusions: This pilot study demonstrated the feasibility of a procedure-focused escape room for teaching high-stakes technical skills. We identified 3 lessons in procedure-focused escape room design: set participant caps intentionally, optimize resource usage, and maximize reproducibility. Participating in a single escape room session significantly increased resident self-efficacy. Residents strongly preferred the escape room format over a traditional procedural skills workshop.
RESUMEN
BACKGROUND: At the onset of the coronavirus disease 2019 (COVID-19) pandemic, anesthesiology residency programs were impacted differently due to various factors such as the local severity of COVID-19, exposure to patient suffering, and inability to complete rotations. We sought to investigate the impact of local-level pandemic severity on the well-being of anesthesiology residents. METHODS: This multi-site study surveyed postgraduate year two residents from 15 United States (US) anesthesiology programs using the Perceived Stress Scale, Mini-Z, Patient Health Questionnaire-9,WHO-5 Well-Being Index,and the Multidimensional Scale of Perceived Social Support before the pandemic (baseline survey) and during the first COVID-19 surge (post survey). RESULTS: A total of 144 (65%) residents responded to the initial baseline survey; 73 (33%) responded to the post survey, and 49 (22%) completed both surveys. There was not a statistically significant difference in any well-being outcomes of participants between the surveys, nor was there a significant difference based on the severity of COVID-19 impact at the program's hospital. Male participants had higher perceived stress scores (ß = 4.05, 95%CI: 0.42, 7.67, P = 0.03) and lower social support from family (ß = -6.57, 95%CI: -11.64, -1.51, P = 0.01) at the post survey compared to female participants after controlling for baseline scores. Additionally, married participants or those with domestic partners reported higher perceived social support in the post survey (ß = 5.79, 95%CI: -0.65, 12.23, P = 0.03). CONCLUSION: The local COVID-19 severity at a residency program did not disproportionately impact well-being scores among anesthesiology residents. Those most vulnerable to diminished well-being appeared to be male and single participants. As a result, targeted well-being interventions, including those aiming to increase social support, to higher-risk resident groups may be indicated. Future work is needed to assess the longstanding COVID-19 pandemic impacts on resident well-being.
RESUMEN
BACKGROUND: Cricothyrotomy is a final recourse for salvaging a difficult airway, yet most anesthesiology providers have little training, exposure, or comfort with the procedure. Pig tracheas are frequently used for training, but are single use and require special handling and storage. Other simulation models, such as mannequins and cadavers, are costly. Advances in 3dimensional (3D) printing have improved accessibility and decreased costs. This research project sought to determine whether an inexpensive 3D-printed task trainer was noninferior to pig tracheas for teaching surgical cricothyrotomy skills. METHODS: Anesthesiology residents were enrolled in an institutional review board-exempted, unblinded, randomized, controlled, single-institution, noninferiority trial. Participants were trained in the scalpel-finger-bougie technique for surgical cricothyrotomy. Participants were randomized to practice 5 repetitions on either a pig trachea or the 3D model and were assessed on time to cricothyrotomy completion on a pig trachea before and after practice. RESULTS: Demographic characteristics of the 25 workshop attendees were similar between study arms. Overall mean (SD) improvement in speed was 9 (12) seconds (P = .001). Postpractice times were similar between groups (analysis of covariance estimated difference of -0.1 seconds [95% confidence interval, -9.4 to 9.2]; P = .55). The 3D model was noninferior to the pig trachea at the prespecified noninferiority margin of 10 seconds (P = .017). CONCLUSIONS: The 3D model was noninferior to pig tracheas for improving the time to completion of a surgical cricothyrotomy. A 3D-printed model offers a viable alternative to pig tracheas for emergency airway simulation that is inexpensive, reusable, and readily modified to simulate challenging airway anatomy.
RESUMEN
BACKGROUND: Dyad learning has been shown to be an effective tool for teaching procedural skills, but little is known about how dyad learning may impact the stress, anxiety, and cognitive load that a student experiences when learning in this manner. In this pilot study, we investigate the relationship between dyad training on stress, anxiety, cognitive load, and performance in a simulated bradycardia scenario. METHODS: Forty-one fourth-year medical school trainees were randomized as dyads (n = 24) or individuals (n = 17) for an education session on day 1. Reassessment occurred on day 4 and was completed as individuals for all trainees. Primary outcomes were cognitive load (Paas scale), stress (Cognitive Appraisal Ratio), and anxiety levels (abbreviated State-Trait Anxiety Inventory). Secondary outcomes were time-based performance metrics. RESULTS: On day 1 we observed significant differences for change in anxiety and stress measured before and after the training scenario between groups. Individuals compared to dyads had larger mean increases in anxiety, (19.6 versus 7.6 on 80-point scale, p = 0.02) and stress ratio (1.8 versus 0.9, p = 0.045). On the day 4 post-intervention assessment, no significant differences were observed between groups. Secondary outcomes were significant for shorter time to diagnosis of bradycardia (p = 0.01) and time to initiation of pacing (p = 0.04) in the dyad group on day 1. On day 4, only time to recognizing the indication for pacing was significantly shorter for individual training (hazard ratio [HR] = 2.26, p = 0.02). CONCLUSIONS: Dyad training results in lower stress and anxiety levels with similar performance compared to individual training.

BACKGROUND: The initial weeks of clinical anesthesiology are a formative period for new residents. Trainees may be clinically educated by a variety of individuals, and introductory didactic structure likely differs between institutions. This study was undertaken to define current orientation practices in US anesthesiology residency programs. METHODS: A survey was created using Qualtrics© software and distributed to all US anesthesiology residency program directors through the Society of Academic Associations of Anesthesiology & Perioperative Medicine email newsletter and through direct email to program directors. RESULTS: Fifty-six unique survey responses were received of 156 total programs. Eighty-nine percent of programs with an integrated intern year begin anesthesia-related orientation before the first year of clinical anesthesiology. Sixty-three percent of programs pair trainees with more than one specific individual during orientation. Programs most frequently pair trainees with anesthesiologists (75%) and/or senior residents (70%). Forty-six percent maintain this pairing for 4 weeks and 30% for 6 weeks or longer. Forty-three percent provide education on teaching practices to trainers. Introductory didactics last a median of 30 hours. Programs may blend lectures, simulations/workshops, digital content, problem-based learning, pocket references, and/or checklists into a cohesive introductory curriculum. Fifty-six percent begin call responsibilities in the sixth week of orientation or later. CONCLUSIONS: Orientation practices for clinical anesthesia training vary across residency programs in the United States. We hope this information will help program directors compare their orientation practices to other programs and identify best practices and potentially useful variations.
RESUMEN
Although ambulatory surgery offers patients convenience and reduced costs, same-day cancellation of ambulatory surgery negatively affects patient experiences and operational efficiency. We conducted a retrospective analysis to determine the frequency and reasons for same-day cancellations in an outpatient surgery center at a large academic tertiary referral center. Of 41 389 ambulatory surgical procedures performed, same-day cancellations occurred at a rate of 0.5% and were usually unforeseeable in nature. Focusing on foreseeable cancellations offers opportunities for enhanced patient satisfaction, improved quality of care, and systems-based practice improvements to mitigate cancellations related to areas such as scheduling or patient noncompliance.

OBJECTIVE: To examine association of presenting clinical acuity and Glasgow Aneurysm Score (GAS) with perioperative and 1-year mortality. DESIGN: Retrospective chart review. SETTING: Major tertiary care facility. PARTICIPANTS: Patients with ruptured abdominal aortic aneurysm (rAAA) from 2003 through 2013. INTERVENTIONS: Emergency repair of rAAA. MEASUREMENTS AND MAIN RESULTS: The authors reviewed outcomes after stable versus unstable presentation and by GAS. Unstable presentation included hypotension, cardiac arrest, loss of consciousness, and preoperative tracheal intubation. In total, 125 patients (40 stable) underwent repair. Perioperative mortality rates were 41% and 12% in unstable and stable patients, respectively (p<0.001). Unstable status had 88% sensitivity and 41% specificity for predicting perioperative mortality. Using logistic regression, higher GAS was associated with perioperative mortality (p<0.001). Using receiver operating characteristic analysis, the area under the curve was 0.72 (95% CI, 0.62-0.82) and cutoff GAS≥96 had 63% and 72% sensitivity and specificity, respectively. Perioperative mortality for GAS≥96 was 51% (25/49), whereas it was 20% (15/76) for GAS≤95. The estimated 1-year survival (95% CI) was 75% (62%-91%) for stable patients and 48% (38%-60%) for unstable patients. Estimated 1-year survival (95% CI) was 23% (13%-40%) for GAS≥96 and 77% (67%-87%) for GAS≤95. CONCLUSIONS: Clinical presentation and GAS identified patients with rAAA who were likely to have a poor surgical outcome. GAS≥96 was associated with poor long-term survival, but>20% of these patients survived 1 year. Thus, neither clinical presentation nor GAS provided reliable guidance for decisions regarding futility of surgery.

BACKGROUND: Insurance-related outcomes disparities are well-known, but associations between distinct insurance types and trauma outcomes remain unclear. Prior studies have generally merged various insurance types into broad groups. The purpose of this study is to determine the association of specific insurance types with mortality after blunt injury. MATERIALS AND METHODS: Cases of blunt injury among adults aged 18-64 y with an injury severity score >9 were identified using the 2007-2009 National Trauma Data Bank. Crude mortality was calculated for 10 insurance types. Multivariable logistic regression was employed to determine difference in odds of death between insurance types, controlling for injury severity score, Glasgow Coma Scale motor, mechanism of injury, sex, race, and hypotension. Clustering was used to account for possible inter-facility variations. RESULTS: A total of 312,312 cases met inclusion criteria. Crude mortality ranged from 3.2 to 6.0% by insurance type. Private Insurance, Blue Cross Blue Shield, Workers Compensation, and Medicaid yielded the lowest relative odds of death, while Not Billed and Self Pay yielded the highest. Compared with Private Insurance, odds of death were higher for No Fault (OR 1.25, P = 0.022), Not Billed (OR 1.77, P < 0.001), and Self Pay (OR 1.77, P < 0.001). Odds of death were higher for Medicare (OR 1.52, P < 0.001) and Other Government (OR 1.35, P = 0.049), while odds of death were lower for Medicaid (OR 0.89, P = 0.015). CONCLUSIONS: Significant differences in mortality after blunt injury were seen between insurance types, even among those commonly grouped in other studies. Policymakers may use this information to implement programs to monitor and reduce insurance-related disparities.
