Paracervical block is effective in relieving painful uterine contractions in the first and second stages of labor, as was introduced by Rosenfeld in 1945. Paracervical block anesthesia is obtained by the deposition of the local anesthetic solution into the paracervical tissue. 92 patients were undergone paracervical block for clinical observation of anesthetic method, effect, duration, fetal heart rate, maternal complication and Apgar scores of neonates. The method used was multiple injections given into four paracervical areas, namely at 3, 4, 8 and 9 c`clock positions, The needle was inserted approximately 1 or 1.2cm., and 1% lidocaine was then injected. Complete relief of pain was obtained in 84 per cent and duration of action was average 30 or 40 minutes. Ten patients developed fetal bradycardia after paracervical block, but all neonates who had bradycardia were discovered to be in good condition, Apgar score being 7 or above in 5 minutes. Maternal complication involved were of littel significance. Paracervical block is simple, and it is safe for the mother and/or for the neonate.
