Model of Eberhart et al for Predicting Postoperative Vomiting in a Pediatric Patient (POVOC-Score)

Purpose: To evaluate a pediatric patient for the risk of postoperative vomiting using the POVOC score of Eberhart et al.

Description

Eberhart et al developed a model for predicting postoperative vomiting (PV) in a pediatric patient. This can help identify a patient who may benefit from closer monitoring and preventive measures. The authors are from Philipps University (Marburg), University of Wurzburg, and the Ambulatory Surgical Center Soflingen (Ulm) in Germany.


Parameters:

(1) type of surgery

(2) age of the patient

(3) duration of surgery

(4) history of postoperative vomiting (PV) or nausea and vomiting (PONV)

= (1.465 * (points for type of surgery)) + (1.204 * (points for age of the patient)) + (1.179 * (points for duration of surgery)) + (1.445 * (points for history of PONV)) - 2.786

 

probability of postoperative vomiting =

= 1 / (1 + EXP((-1) * X))

 

Interventions:

(1) trying to shorten the duration of the procedure

(2) selection of a pain medicine that is less emetogenic

(3) use of a prophylactic drug to reduce nausea and/or vomiting
