Abstract To study the anesthetic effect of remifentanil on painless induced abortion. Methods: 118 women experienced painless abortion were divided into two groups according to different anesthesia schemes from February 2017 to December 2018. The women in the observation group were given remifentanil combined with propofol, and the women in the control group were given propofol. The anesthetic effect of women was compared between the two groups. Results: The dosage of propofol used, the amount of bleeding during the operation, the time of consciousness recovery, and the time of directional force recovery of women in the observation group was 105.9±4.8mg mg, 20.1±5.7ml, 1.8±0.7min, and 3.1±0.6min, which were significant less than those of women in the control group (all P<0.05). There were no significant different in the values of mean arterial pressure (MAP), heart rate (HR), blood oxygen saturation (SPO2), and respiratory rate (RR) of women when consciousness lost before anesthesia between the two groups (P>0.05). The the values of MAP and HR of women when dilation and curettage in the observation group were significant lower than those of women in the control group (P<0.05), but the values of SPO2 and RR of women when dilation and curettage in the observation group had no significant different from those of women in the control group (P>0.05). The rate of analgesia excellent or good of women in the observation group was 88.1%, which was significant higher than that (69.5%) of women in the control group (P<0.05). There were no significant difference in the levels of angiotensin Ⅰ and angiotensin Ⅱ of women before and after operation between the two groups (P> 0.05). The complication rate of women in the observation group was 3.4%, which had no significant different from that (5.1%) of women in the control group (P=0.648). Conclusion: The application of remifentanil combined with propofol in painless abortion has the characteristics of quick onset of anesthesia, rapid recovery, and high safety.
