Ashrafun Nessa, Irfan Ahmed Aberdeen Royal Infirmary Aim: In the preoperative assessment of a surgical patient, it is prudent to counsel the patient on the risks of postoperative mortality and need for critical care monitoring after surgery, identifying patients for prehabilitation, perioperative shared decision-making process, guiding allocation of resources and improving patient outcomes. WS4.269 Preventing Post-operative Nausea and Vomiting (PONV) - are we doing enough for day case patie... Will Sargent, Emma Gorst Ealing Hospital, London North West University Healthcare Aim: • Enhanced recovery protocols recommend risk-stratification of patients and tailoring of antiemetic prophylaxis accordingly to prevent post-operative nausea and vomiting (PONV) • The widely-used Apfel score for PONV risk was created before the routine propofol induction and antiemetic prophylaxis • As more procedures are performed as day case, patients may be sent home before PONV manifests • We wanted to see how effective our current strategies are at preventing post-operative PONV Method: • 65 patients undergoing general surgical or gynaecological procedures were prospectively risk-stratified for PONV according to their Apfel score (high risk >2) • Their anaesthesia and intra-operative prophylactic antiemesis was recorded from the anaesthetic chart • They were asked about PONV at 2 and 24 hours after their operation end, the latter by telephone Results • 24.2% (15/62) patients were nauseated after leaving hospital • 35.5% (11/31) high-risk patients experienced PONV vs 12.9% (4/31) in the low-risk group (p <0.05, Fisher's exact test) • There was no difference in the number of antiemetic agents used between high- and low-risk groups (median 2).
