Abstract
Sleep-disordered breathing (SDB) may be a critical risk factor for emergence agitation (EA). We hypothesized that SDB diagnosis is apredictor of EA in children after general anesthesia for ambulatory surgery. Prospective, observational, cohort study. Children aged 4 to 17 years were assessed for the occurrence of EA. Differences in probability of EA were assessed using multivariable logistic regression analyses. Of 1,076 children, 66 (6.1%) had EA. Compared with those without EA, children with EA were younger (P < .001), more likely to have had mask induction (P < .001) and a preoperative diagnosis of SDB (P = .008). On multivariable analysis, SDB, severe obesity, decreasing age in years, increasing first arousal pain score, and intraoperative use of sevoflurane were independently associated with EA. SDB and severe obesity may be critical independent predictors of EA in children. Mechanisms underlying these observations deserve further elucidation.
