The Effect of Remifentanil and Fentany in Painless Induced Abortion

objective To investigate the efficacy and safety of painless induced abortion with a combined use of propofol and remifentanil.Methods Fourty five patients undergoing elective abortion were divided into three groups:the fentanyl group,remifentanil 2ng group and remifentanil 3ng group.Several factors including the dose of propofol,recovery time after anesthesia,body movement,respiration weakness and post-operation bellyache etc were observed.Results The total doses of propofol during anesthes in the fentanyl group was greater than that in the remifentanil 2ng group and the latter was greater than that in the remifentanil 3ng group;The recovered time in the remifentanil group was quicker than that in the fentanyl group and remifentanil 3ng group.Respiration weakness was appeared in all two groups in the of remifentanil and body movement was similar in the three groups;Compared with two remifentanil groups,the rate of post-operation bellyache in fentanyl group was increased significantly.Results Target-controlled infusion of remifentanil used in painless induced abortion had some advantage, but attention must be paid to respiration management.Compared with the dose of 3ng/ml remifentanil,2ng/ml remifentanil had some advantages.
