The Assessment of Postoperative Nausea and Vomiting (PONV) using Rhodes Index in PONV High Risk Group / 대한마취과학회지

ABSTRACT

BACKGROUND: The Rhodes index of nausea, vomiting and retching (RINVR) is a reliable and valid instrument to assess PONV. The purpose of this study was to investigate the incidence of PONV in high risk group with using RINVR. METHODS: Patients scheduled for elective surgery under general anesthesia were classified in three groups (group Itwo risk factors, group IIthree risk factors, group IIIfour risk factors) by using a simplified risk score.We investigated the incidences of PONV in each group. RESULTS: The incidence of PONV was 12.8% in group I, 25% in group II, and 33.1% in group III, which showed a significant difference between group I and group II, between group I and group III.The incidence of PONV, which was over moderate was significantly increased in group III. CONCLUSIONS: For patients with three or four risk factors a multimodal antiemetic strategy should be considered.
