Abstract:
Objective To explore the influence of using lidocaine in the second stage of labor among primiparas. Methods 300 primiparas were divided into three groups. When Group A has uterus contractions with anal fold releasing, bilateral pudendal nerve was conducted by block anesthesia with lidocaine hydrochloride. When Group B has the uterus contractions with head visible on vulva gapping 2～3 cm, lidocaine hydroctdoride bilateral pudendal nerve was carried out by block anesthesia. Group C was not carried out any measures. Results The shortest time of the second stage is Group A. Group C is the longest one. Pain in groups A, B significantly reduced than in group C. The condition of perineum in Group A and B were better than that of in Group C, the rate of postero-lateral episiotomy and the level of perineal laceration in Group C were higher. Conclusions Bilateral pudendal nerve block anesthesia can shorten the second stage of labor and suturing time, alleviate the pain of delivery, reduce the rate of postero-lateral episiotomy and the perineal laceration, and raise the rate of perineal integrity. Compared with the head visible on vulva gapping, dilatation of cervix 10 cm can get the better effect of shortening the second stage of labor.
