The baby’s position in the uterus is called the fetal position, head down is cephalic, head up is breech, and when the axial position is transverse, the fetal preexisting part of the shoulder or hand is transverse. When the fetal position is breech, it can be changed to cephalic position by chest-knee recumbency and external breech inversion, which are also important measures to ensure a smooth delivery. 1. Knee-chest position: Before doing the movement, urinate and empty the bladder, wear loose clothes, relax, turn your face to the side, keep your chest as close to the bed as possible, kneel on the bed with your legs shoulder-width apart and keep your thighs perpendicular to the bed, 2-3 times a day for about 15 minutes each time. 2. External breech inversion: this technique is done by obstetricians with the cooperation and guarantee of ultrasonographers, anesthesiologists and many other disciplines, as well as certain risks, and is usually performed at 36-37 weeks. There are indications and contraindications for both the knee-chest position and the external breech inversion. If the ultrasound during the delivery suggests that the baby is not in the correct position, it is recommended that you consult an obstetrician in time to complete the procedure under your doctor’s supervision.
