A unique and highly rated anaesthesia faculty course was created; participation made the faculty staff eligible for malpractice premium reductions. Self-reported CRM behaviours in participants' most significant difficult or critical events indicated an improvement in performance. These data provide indirect evidence supporting the contention that this type of training should be more widely promoted, although more definitive measures of improved outcomes are needed.
Objective: Simulation is a tool that has been used successfully in many high performance fields to permit training in rare and hazardous events. Our goal was to develop and evaluate a program to teach airway crisis management to otolaryngology trainees using medical simulation. 92 (SD, 0.28). Sample comments include: "This is a valuable tool for students and residents since true emergencies in ORL are often lifethreatening and infrequent," and "This is a great course-really all physicians should experience it." Overall evaluation was extremely positive and both residents and fellows described the course as filling an important void in their education. Conclusion: Medical simulation can be an extremely effective method for teaching airway crisis management and teamwork skills to otolaryngology trainees at all levels.
The causes of obstruction to airflow in the pediatric upper airway include craniofacial disorders, subglottic stenosis, choanal atresia, syndromes associated with neuromuscular weakness, and the most common, hypertrophy of the tonsils and adenoids. Abnormal breathing can adversely affect craniofacial growth, and abnormal craniofacial development can promote upper airway obstruction. Chronic upper airway obstruction often presents with evidence of obstructive sleep apnea syndrome; in severe cases these children also present with pulmonary hypertension and cor pulmonale. The development of pulmonary hypertension and right heart dysfunction from chronic upper airway obstruction is complex. Hypoxemia and hypercarbia-induced respiratory acidosis are potent mediators of pulmonary vasoconstriction that can lead to reversible and irreversible chronic changes in the pulmonary vasculature. It is likely that production of various neurohumoral factors in response to hypoxemia and respiratory distress may further promote pulmonary hypertension, right ventricular dysfunction, and consequent impairment of systemic cardiac output. The anesthetic considerations for children undergoing adenotonsillectomy for chronic airway obstruction are significant. These children are at high risk for complications such as laryngospasm, desaturation, stimulation of pulmonary hypertension and cardiac dysfunction, pulmonary edema, postoperative upper airway obstruction, and respiratory arrest. Because of underlying condition(s) (facial abnormalities, neuromuscular disease, etc.), successful adenotonsillar surgery may not improve upper airway obstruction significantly, especially in the immediate postoperative period when edema, bleeding and the effects of anesthetics and analgesics are present.
Team behavior and coordination, particularly communication or team information-sharing, are critical for optimizing team performance; research in medicine generally provides no accepted method for measurement of team information-sharing. In a controlled simulator setting, we developed a technique for placing clinical information (probes) with members of a team of trainees participating in a 1-day Anesthesia Crisis Resource Management course and later tested the teams for knowledge of the probes as an indicator of overall team information-sharing. Despite the low level of team information-sharing, we demonstrated construct validity of the probe methodology by the correlation of measured change in team information-sharing from beginning to end of training with self-rated change. There was no statistical difference in "group sharing" from beginning to end of training, despite trainees' survey responses that the course would be useful for their education and practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
