Prolonged recovery after out-patient pediatric adenotonsillectomy

To determine variables predictive of recovery room times in pediatric outpatient adenotonsillectomy.

Retrospective case-control.

One-hundred ninety consecutive patients undergoing outpatient adenotonsillectomy at an ambulatory surgery center of a tertiary-care free standing pediatric hospital were grouped into upper and lower deciles of recovery room times. Twenty-one variables were analyzed to determine which variables are predictive of prolonged recovery time. Univariate and multivariate analyses were performed.

Of the 190 patients, mean recovery room time was 103 min (SD 53.1), 22 patients were in the lower decile (mean recovery room time of 63 ± 6 min) and 17 patients were in the upper decile (155 ± 40 min, P<0.0001). Of the 21 variables analyzed, post-anesthesia care unit (PACU) nursing staff was the only significant predictor of prolonged recovery room time. Compared with one PACU nurse, other nurses (N=5) predicted a longer recovery time (OR=10.8, 95% CI 2.0-59.5, P=0.0017). This association remained significant when controlling for anesthesiologist and surgeon (OR=8.8, 95% CI 1.5-50.9, P=0.0072). There were no complications in any patients.

Recovery room times after outpatient adenotonsillectomy vary significantly (mean 103 min (SD 53.1), range 50-241 min). Of potential predictors, only the human factor (PACU nursing staff) was associated with prolonged recovery room times, independent of surgeon and anesthesiologist. Development of standardized protocols for nurses to use for discharge has the potential to increase throughput for adenotonsillectomy patients in an outpatient surgery center setting.
