The parents were asked to complete the PPPM Parent questionnaire(Appendix 1) on postoperative day 0, days 1-3 and days 8-10 based on parent availability. On the day of surgery(POD 0) the PPPM was completed by the anaesthetist on the paediatric ward or via telephone call if the patient had been discharged. The following PPPM on POD 1-3 and POD 8-10 was done via a telephone call by an anaesthetist. Oxycodone usage(mg/kg) were recorded over the 24 hours immediately following surgery as well as number of episodes of nausea or vomiting. This was recorded by the nursing staff as part of the medication record and nursing notes
