Abstract:
Objective To compare different dose of remifentanil combined with propofol for painless abortion and approach to an appropriate dose of remifentanil.Methods Ninety pregnant women with ASA 1 were randomly divided into three groups(n=30)before administrating remifetanil,a bolus midazolam 1 mg was injected inminutes later.These two drugs did not stop administration until three minutes before the end of negative suction.MAP,HR,SpO2,BIS,RR,VT,PET CO2 were monitored.The onset,operation and recovery time,sedation score and adverse reaction were recorded.Results Sedation scores were significantly different between group A and C [(3.90±0.97)and(4.90±0.85),t=4.24,P＜0.01].Three cases in group A were found moving.MAP,HR,BIS decreased as compared witll baseline.HR reduced significantly in group C(P＜0.05,P＜0.01).Respiratory movement was lower and shallower.RR,VT decreased compared to preoperative one.PET C02 increased gradually (P＜0.05,P＜0.01).There were two cases of respiratory depressing in group A,four cases in group B and ten cases in group C(five cases apnea more than three minutes).All patients used oxygen mask to maintain SpO2＞95%.Incidence of adverse reactions such as chest titanic,nausea and vomiting,itching were of no difference among three groups(P＞0.05).All patients were satisfied with anesthesia.Conclusion The appropriate infusing dose of remifetory devices such as oxygen mask and monitoring life signs are very important to prevent respiratory depress and bradycardia during operation.
