Choi YS et al. – The antiemetic efficacy of ramosetron plus dexamethasone was similar to that of ondansetron plus dexamethasone on preventing postoperative nausea and vomiting (PONV) in high–risk patients undergoing lumbar spinal surgery.Methods
- In this randomized, double–blind study, 120 female non–smoking patients with intravenous patient–controlled analgesia (PCA) received ramosetron 0.3mg plus dexamethasone 5mg (group R+D) or ondansetron 4mg plus dexamethasone 5mg (group O+D) intravenously.
- Fentanyl–based PCA was administered for 48hr postoperatively; ramosetron 0.3mg or ondansetron 12mg was added to the PCA regimen according to the allocated group.
- The incidence of PONV and rescue antiemetic were assessed for 48hr postoperatively at 0–6, 6–24, and 24–48hr.
- The overall incidence of PONV did not differ between the groups (50% vs. 60%, in groups R+D and O+D, respectively).
- The overall incidence of nausea was similar between groups (47% vs. 60%, in groups R+D and O+D, respectively).
- The overall frequency of vomiting was also similar between groups (8% vs. 12%, in groups R+D and O+D, respectively).
- The severity of nausea and the overall use of rescue antiemetic were not different between groups.
