Objective To investigate the effect of pre-birth acupressure points massage of the breasts on labor process and post partal lactation. Methods A total of 100 multiparas with full-term pregnancy but no signs of uterine contraction were sequencially divided into two groups, with 50 women in each group. In the experimental group, the midwife massaged the acupressure points of the mothers′ breasts twice a day, 30 minutes each time. The control group was given routine nursing care. The ute-rine contractions, labor duration and the time to lactation initiation were compared between the two groups. Results The rates of mothers with regular uterine contractions, and successful delivery on the 1st, 2nd, and 3rd day of admission had significant differeces between the two groups （P＜0.01）, likewise for the rates of lactation on the 1st, 2nd, and 3rd day of birth. The experimental group had shorter second, and third stages of labor, and shorter total length of stages of labor than the controls （P＜0.01 for all）.
