We sought to describe the physiologic and biochemical stress response induced by simulated patient death as well as the impact on long-term retention of Advanced Cardiovascular Life Support (ACLS) knowledge and skills. Twenty-six subjects received an American Heart Association (AHA) ACLS provider course. Following the course, subjects participated in HFS and were randomized to simulated death or survival. Heart rate and salivary cortisol (SC) and dihydroepiandrosterone (DHEA) were collected at this time. Subjects returned six months later for a follow-up simulation in which ACLS knowledge and skills were tested. For all participants, there was an increase in heart rate during simulation compared with baseline heart rate (+ 32 beats/minute), p < 0.0001. Similarly, SC and DHEA were higher compared with baseline levels (+ 0.115 μg/dL, p <0.01 and + 97 pg/mL, p < 0.001, respectively). However, the only statistically significant difference between groups was an increase in heart rate response at the end of the simulation compared with baseline in the death group (+ 29.2 beats/minute versus + 18.5 beats/minute), p < 0.05. There was no difference on long-term knowledge or skills. Learners experience stress during high-fidelity simulation; however, there does not appear to be a readily detectable difference or negative response to a simulated patient death compared with simulated survival.

The goal of this study was to determine if participation in a series of anesthesiologist-run, simulation-based physiology labs changed first year medical students' perceptions of anesthesiologists. Methods: One hundred first-year medical students were surveyed at random three months before completion of a simulation-based physiology lab run by anesthesiologists. All participants received the same survey instrument, which employed a 5-point Rating Scale to rate the appropriateness of several descriptive terms as they apply to a particular specialist or specialty. A post-simulation survey was performed to track changes in attitudes. Results: Response rates to the survey before and after the simulation labs were 75% and 97% (ofthe initial cohort responding), respectively. All students who filled out the post-simulation surveys had been exposed to anesthesiologists in the prior three months whereas none had interacted with surgeons in the interim. Nearly all had interacted with internal medicine specialists in that time period. No changes in the medical students' perceptions of surgeons or internal medicine specialists were evident. Statistically significant changes were found for most descriptors of anesthesiologists, with a trend towards a more favorable perception after the simulation program. Conclusions: Using a survey instrument containing descriptors of different medical specialists and specialties, we found an improved attitude towards anesthesiology after medical students participated in an anesthesiologist-run simulation-based physiology lab series. Given the importance of providing high quality medical education and attracting quality applicants to the field, integrati-on of anesthesiology staff into medical student courses at the non-clinical level appears useful.

Full environment simulation (FES) can be employed to effectively replicate rare medical catastrophes with exacting realism. It has been suggested that emotion can significantly enhance learning by producing memories that are processed and stored via the amygdaloid complex which is relatively impervious to extinction and thus forgetting. Theoretically the addition of emotional content to simulated crises during FES can be used to affect such changes in the participants and thus facilitate learning. We discuss the theoretic benefit and the use of FES with emotional enhancement as it relates to improved memory and learning.

Using a randomized, controlled, observer-blinded design, we compared performance of anesthesiology residents in a simulated operating room using a checklist in completing a thorough pre-anesthetic induction evaluation and setup, to residents with no checklist. The checklist was implemented through a "hard stop" in the simulated electronic medical record. Data for 24 CA-1 residents show a statistically significant difference in performance in pre-anesthetic setup and evaluation as scored by blinded raters, with the checklist group performing better.

Although its efficacy for education and evaluation in the medical community has been well established through extensive research, there is a distinct dearth in the literature in its use for anesthesia trainee education and evaluation. In this article, we discuss this simulation modality via a historic review, its current application in competency assessment, and its use in anesthesiology education and evaluation. We conclude with a "how to guide" to facilitate those considering including standardized patient simulations into their anesthesia training or simulation curriculum.

Individuals may return to clinical practice after a short period of treatment only to relapse into active addiction, and for the opioid addicted anesthesia resident, this often results in death. The objective of this study was to determine weather or not a period of time away from clinical practice after treatment would reduce the rate of relapse by allowing the individual to concentrate on recovery in the critical first year after treatment, during which the majority of relapses occur. 5 residents identified as being addicted to a controlled substance were removed from residency training and offered treatment. Prior to returning to residency training they were required to complete a post-treatment program involving no less than 12 months of work in the anesthesia simulator, followed by a graded re-introduction into the clinical practice of anesthesia. Academic anesthesia practice in a large teaching hospital. Of the 5 residents who participated in the program, 3 (60%) successfully completed their residency program and their 5 year monitoring contract, and entered the anesthesia workforce as attending anesthesiologists. The treatment of addicted physicians can be successful, and return of the highly motivated individual to the clinical practice of Anesthesiology is a realistic goal, but this reintroduction must be undertaken in a careful, stepwise fashion. A full understanding of the disease process, the potential for relapse, and the implications of too rapid a return to practice must be taken into careful consideration.

All participants in this study will be exposed to the same clinical scenario but one group will experience a "hard stop" in the documentation workflow. We hope to use the Results of this study to validate the simulated environment as an effective and novel way to inform the implementation and further study of patient safety and quality improvement initiatives that may be difficult to clinically test. Methods: Using a randomized, controlled, observer-blinded design, we compare performance of anesthesiology residents using the APSF PIPS checklist in completing a thorough pre-anesthetic induction evaluation and setup, to residents with no checklist.6 The study is performed using the METI high-fidelity simulator. The simulated OR is set up to represent a previously used anesthesia machine/cart that has not been set up for a new anesthetic, and is missing the components highlighted in the PIPS checklist. The residents will be called in to provide anesthesia for a case that was booked initially as a case only requiring local anesthesia. The surgeon will create time pressure for the residents to induce anesthesia prematurely in this entirely elective setting. In the experimental group, the electronic medical record will create a "hard stop" in which the APSF PIPS checklist is displayed and must be checked and signed off on before any further documentation of the anesthetic can occur. In the control group, this "hard stop" will not be present in the electronic medical record. The simulation will end when the resident provides any medication to the patient, and missed steps will be recorded at that time. The hypothesis is that the required use of the APSF PIPS checklist prevents missed steps in the pre-anesthetic set up under time pressure in a simulated operating room. Results: Conclusion: Our study illustrates the importance of the simulated environment in evaluation of new patient safety and quality improvement initiatives as the specific situations in which such initiatives are likely to increase patient safety can never be ethically or successfully replicated in real life.

This surgery carries certain risks. Most of these risks relate to the quality of the surgical field. Thus, mechanisms by which the surgical field can be improved are important to study. We sought to determine whether positive end-expiratory pressure (PEEP) had a deleterious effect on the quality of the surgical field in patients undergoing primary FESS. Forty-seven patients were randomized to a ventilation strategy using either 5 cm H2O of PEEP or zero added PEEP. The quality of the surgical field was measured every 15 minutes using a validated surgical scoring method. The addition of PEEP did not have any measurable effect on the surgical field scores after onset of surgery (odds ratio [OR] (95% confidence interval [CI]) = 1.06 (0.44-2.58), P = 0.895 for side 1; OR (95% CI) = 0.56 (0.16-1.93), P = 0.356 for side 2). The peak inspiratory pressure did have an effect on surgical grades. Every cm H2O of added pressure over 15 cm H2O total pressure contributing to increased odds of higher surgical field score. For each cm H2O increase in inspiratory pressure above 15cm H2O increased the surgical field score (OR [95% CI] 1.13 [1.04-1.22], P = 0.002). During FESS surgery if PEEP is added, it is important to keep the mean inspiratory pressure below 15cm H2O to avoid worsening surgical field conditions.

This anilidopiperidine analog of fentanyl was approved by the United States Food and Drug Administration and became commercially available in the United States in 1997. Because of its unique chemical structure, remifentanil must be reconstituted; it has a rapid onset, and because of ester hydrolysis, it has a rapid rate of degradation. Although remifentanil's package insert warns against the potential for addiction, because of its rapid rate of degradation there was little concern that health care workers would abuse this drug. Herein, we report a case of intranasal remifentanil abuse by an anesthesiology resident.
