Objective: To explore a simple and effective analgesia in induced abortion. Methods: Six to 12 weeks pregnant, 160 healthy pregnant women requiring termination of pregnancy were randomly divided into two groups. The patients in the anesthesia group were treated with 2% lidocaine and cervical paralysis followed by artificial abortion, and the control group without adjuvant drugs. Results: The total effective rate of analgesic effect and cervical relaxation were 94% and 91% respectively in the anesthetic group and 58% and 33% in the control group respectively. There was significant difference between the two groups (2.0% vs 8.3%, respectively) (P <0.01). There was no significant difference in the contractions rate and bleeding between the two groups P> 0.05). Conclusion: 2% lidocaine cervical paraquat is a simple and effective method of analgesia.
