BackgroundA score to predict postoperative vomiting (PV) in children (POVOC score) has recently been published but has not yet undergone an external validation.MethodsWe studied 673 patients (age 0-16 yr) undergoing a variety of surgical procedures (but excluding strabismus surgery, one of the risk factors according to the POVOC score) using standardized anesthesia techniques without administering antiemetics. The patients were prospectively screened for PV in the postoperative period and these incidences were compared with the predicted risk for PV according to the POVOC score. The POVOC score was evaluated with respect to its ease of use, discrimination, and calibration.ResultsComplete data to predict the risk for PV could be obtained in 95% of patients. The actual observed incidences of PV were 3.4, 11.6, 28.2, and 42.3% for the presence of 0, 1, 2, or 3 risk factors, resulting in a regression line with a slope of 0.78 and an offset of 2.37. The area under the receiver operating characteristic curve was 0.72 (95% CI: 0.68-0.76).ConclusionsUsing the POVOC score, PV in pediatric patients can be predicted with sufficient accuracy comparable to the results in adult patients, even if one of the risk factors is not applicable.
