[Air sac midwifery technique for shortening course of labor].
Air sac midwifery technique is developed in this hospital to cut down the duration of labor (birth process). A special small sac is placed inside the ripe cervix and vagina of women of term pregnancy, and aerated slowly till a positive pressure of 16-25 kPa is reached. The cervix can be dilated to 6 to 8 cm, and the vagina 10 to 12 cm in 1 to 2 minutes. The labor course may be cut down by 8 to 10 hours, thus relieving the parturient from pain, lessening perineal laceration and perinatal mortality which is important for eugenics sake.
