ABSTRACT
OBJECTIVE:To observe the effect of ondansetron on the anesthesia of cesarean section surgery with spinal-epidur-al anesthesia. METHODS:A total of 60 singletons full-term pregnancy were randomly divided into test group and control group. Test group was given 6% Hetastarch(130/0.4)electrolyte injection 500 ml by intravenous infusion 30 min before anesthesia,and Ondansetreon hydrochloric acid injection 4 ml by intravenous infusion 5 min before anesthesia;control group was given 6% Hetas-tarch(130/0.4)electrolyte injection 500 ml by intravenous infusion 30 min before anesthesia,and 0.9% Sodium chloride injection 4 ml by intravenous infusion 5 min before anesthesia. The clinic data was recorded,including the mean arterial pressure (MAP) and heart rate(HR)before anesthesia puncture(T1),after anesthesia maternal left side(T2),after fetal childbirth(T3)and at the end of surgery(T4),Apgar score and incidence of adverse reactions. RESULTS:MAP in control group at T2,T3 was obviously low-er than T1 and test group,HR was obviously higher than T1 and test group,the difference was statistically significant(P0.05). Apgar score of newborn after 1 min birth in test group was significantly higher than control group,the difference was statistically significant (P0.05). The ADR incidence in test group was significantly lower than control group(P<0.05). CONCLUSIONS:Ondansetron can effectively reduce the inci-dences of vomit vomitting and hypotension in on the cesarean section surgery with spinal-epidural anesthesia,with good safety.
