BACKGROUND : Palonosetron is a new potent 5-hydroxytryptamine 3 antagonist. Although used for chemo induced
emesis, data is lacking for PONV. The high incidence of nausea and vomiting after breast surgery is well documented.
This study compared the effects of i.v.ondansetron and palonosetron administered at the time of induction for preventing postoperative nausea
and vomiting (PONV) in these high-risk patients . The aim was to compare Onda METHODS : nsetron 8 mg and Palonosetron 0.075mg
administered intravenously for prevention of post operative nausea and vomiting in patients undergoing modied radical mastectomy 24 hours
postoperatively, by a randomised , controlled, double blind study. 70 female non smoking patients scheduled for elective modied radical
mastectomy were, allocated randomly into 2 groups . Patients received either Palonosetron 0.075mg (GROUP P ) or ondansetron 8mg ( GROUP
O ) intravenously, immediately before induction of general anaesthesia. The occurence of nausea, vomiting, retching, need for rescue
antiemetics and side effects were monitored for a period of 24 hours after surgery. The compete response rate and overall PONV for 0 - 24 hours
were calculated. The demographic prole of the patients were comparable. The RESULTS : incidence of a complete response (no PONV, no
rescue antiemetics ) during 0 - 24 hours in post operative period was signicantly high in GROUP P ( 85.7% vs 62.9%, p=0.02) than GROUP O.
The incidence of nausea was signicantly low in GROUP P ( 14.3% vs 37.1%). There was no statistically signicant difference between the 2
groups in vomiting, retching, side effects and need for rescue antiemetics. Thus overall PONV was low in GROUP P (14.3% vs 37.1% p = 0.02
statistically signicant.) We conclude that Palonosetron 0.075mg was more effective for preventing PONV in patients undergoing modied
radical mastectomy surgery
