ObjectiveTo determine the incidence of perioperative anesthesia complications during bilateral myringotomy with tympanostomy tube placement (BMTT).SettingTertiary care children's hospital where otolaryngology attending physicians and residents performed surgical procedures. Anesthesia providers included pediatric anesthesiologists, residents, nurse anesthetists, and students.MethodsMedical record review was performed for a consecutive series of 3198 children undergoing BMTT (1000 prospectively, 2198 retrospectively). For the prospectively studied patients, major adverse events, which included laryngospasm and stridor, and minor adverse events, including upper airway obstruction, prolonged recovery, emesis, and persistent postprocedural agitation, were noted. Also recorded were the patient's American Society of Anesthesiologists (ASA) physical class status, age, concurrent medical conditions, and type of anesthesia provider.ResultsFewer than 9% of prospectively studied pediatric patients experienced a minor adverse event, whereas a major event occurred in 1.9%. Eighty-one percent of the events experienced were attributable to agitation or prolonged recovery. Neither ASA status (P =.38), age (P =.15), nor type of anesthesia provider (P =.06) were significantly related to the occurrence of an adverse event. However, a child with an acute or chronic illness has 2.78 times the odds of experiencing an adverse event compared with a child with no illness (P<.001).ConclusionsAnesthesia administered for placement of tympanostomy tubes by physicians who specialize in the care of children in a tertiary care children's hospital is safe. The most significant predictor of a minor anesthetic event during BMTT is the presence of a preexisting medical condition or concurrent acute illness.
