Prevention and Management of Operating Room Fire: An Interprofessional Operating Room Team Simulation Case.

Introduction: Operating room (OR) fire can be a devastating and costly event to patients and health care providers. Prevention and effective management of such fires may present difficulties even for experienced OR staff. Methods: This simulation involved a 52-year-old man presenting for excisional biopsy of a cervical lymph node to be performed under sedation. Participants were expected to identify and manage both contained and uncontained fires resulting from ignition by electrosurgical cautery. We conducted weekly multidisciplinary simulations in the mock OR at Massachusetts General Hospital. Participants included surgery and anesthesiology residents, certified registered nurse anesthetists, registered nurses, and surgical technicians. Participants were unaware of the scenario content. Each 90-minute session was divided into three parts: an orientation (10 minutes), the case with rapid cycle debriefing (65 minutes), and a final debriefing with course evaluations (15 minutes). Equipment consisted of a simulation OR with general surgery supplies, general anesthesia equipment, a high-fidelity Laerdal SimMan 3G simulator, a code cart, a defibrillator, dry ice for smoke effects, and a projector with a fire image. Results: From April to June 2015, 86 participants completed this simulation. Participants reported that the simulation scenario was realistic (80%), was relevant to their clinical practice (93%), changed their practice (82%), and promoted teamwork (80%). Discussion: Prevention and management of OR fire require collaboration and prompt coordination between anesthesiologists, surgeons, and nurses. This simulation case scenario was implemented to train multidisciplinary learners in the identification and crisis management of such an event.

Internal Medicine Residents' Exposure to and Confidence in Managing Hospital Acute Clinical Events.

BACKGROUND: Internal Medicine (IM) residency graduates should be able to manage hospital emergencies, but the rare and critical nature of such events poses an educational challenge. IM residents' exposure to inpatient acute clinical events is currently unknown. OBJECTIVE: We developed an instrument to assess IM residents' exposure to and confidence in managing hospital acute clinical events. METHODS: We administered a survey to all IM residents at our institution assessing their exposure to and confidence in managing 50 inpatient acute clinical events. Exposures assessed included mannequin-based simulation or management of hospital-based events as a part of a team or independently in a leadership role. Confidence was rated on a five-point scale and dichotomized to "confident" versus "not confident." Results were analyzed by multivariable logistic regression to assess the relationship between exposure and confidence accounting for year in training. RESULTS: A total of 140 of 170 IM residents (82%) responded. Postgraduate year 1 (PGY-1) residents had managed 31.3% of acute events independently vs 71.7% of events for PGY-3/4 residents (P < .0001). In multivariable analysis, residents' confidence increased with level of training (PGY-1 residents were confident to manage 24.9% of events vs 72.5% of events for PGY-3/4 residents, P < .0001) and level of exposure, independent of training year (P = .001). Events with the lowest levels of exposure and confidence for graduating residents were identified. CONCLUSIONS: IM residents' confidence in managing inpatient acute events correlated with level of training and clinical exposure. We identified events with low levels of resident exposure and confidence that can serve as targets for future curriculum development.

Identifying and Managing Intraoperative Arrhythmia: A Multidisciplinary Operating Room Team Simulation Case.

Introduction: Resuscitation of a critically ill patient is challenging for both novice learners and experienced health care providers. During a critical event, not only is it important to identify the correct underlying diagnosis, it is equally crucial that the appropriate Advance Cardiac Life Support algorithm, medications, and defibrillator modality are implemented. This scenario features a 56-year-old female who presents for excisional biopsy of an inguinal lymph node to evaluate lymphadenopathy concerning for lymphoma. Intraoperatively, she goes into cardiopulmonary arrest. Participants must identify and manage three different scenarios: (1) ventricular fibrillation, (2) unstable ventricular tachycardia, and (3) bradycardia, including the use of the defibrillator. Method: Weekly simulation sessions were conducted in the in situ simulation operating room at Massachusetts General Hospital. Surgical residents, anesthesiology residents, nurses, and surgical technicians participated in a multidisciplinary operating room team. Each approximately 60-minute session included an orientation, the case, and the debriefing. Equipment included a simulation operating room with general surgery supplies, general anesthesia equipment, a high-fidelity SimMan patient simulator, a code cart, and a defibrillator. Results: Ninety-one multidisciplinary participants completed this scenario from September to December 2015. Participants reported that the scenario was applicable to their clinical practice (96%), promoted teamwork skills (88%), and encouraged interprofessional learning (94%). Discussion: Intraoperative cardiac arrest is a devastating event that can result in poor patient outcomes if the care team is not thoroughly prepared for crisis management. This simulation case scenario was implemented to train multidisciplinary learners in the identification and management of such an event.

Lack of Responsiveness during the Onset and Offset of Sevoflurane Anesthesia Is Associated with Decreased Awake-Alpha Oscillation Power.

Anesthetic drugs are typically administered to induce altered states of arousal that range from sedation to general anesthesia (GA). Systems neuroscience studies are currently being used to investigate the neural circuit mechanisms of anesthesia-induced altered arousal states. These studies suggest that by disrupting the oscillatory dynamics that are associated with arousal states, anesthesia-induced oscillations are a putative mechanism through which anesthetic drugs produce altered states of arousal. However, an empirical clinical observation is that even at relatively stable anesthetic doses, patients are sometimes intermittently responsive to verbal commands during states of light sedation. During these periods, prominent anesthesia-induced neural oscillations such as slow-delta (0.1-4 Hz) oscillations are notably absent. Neural correlates of intermittent responsiveness during light sedation have been insufficiently investigated. A principled understanding of the neural correlates of intermittent responsiveness may fundamentally advance our understanding of neural dynamics that are essential for maintaining arousal states, and how they are disrupted by anesthetics. Therefore, we performed a high-density (128 channels) electroencephalogram (EEG) study (n = 8) of sevoflurane-induced altered arousal in healthy volunteers. We administered temporally precise behavioral stimuli every 5 s to assess responsiveness. Here, we show that decreased eyes-closed, awake-alpha (8-12 Hz) oscillation power is associated with lack of responsiveness during sevoflurane effect-onset and -offset. We also show that anteriorization-the transition from occipitally dominant awake-alpha oscillations to frontally dominant anesthesia induced-alpha oscillations-is not a binary phenomenon. Rather, we suggest that periods, which were defined by lack of responsiveness, represent an intermediate brain state. We conclude that awake-alpha oscillation, previously thought to be an idling rhythm, is associated with responsiveness to behavioral stimuli.
