After the cesarean section, the use of the lap band can be started after the mother is able to urinate on her own and can get out of bed, usually about 24 hours after delivery. The cesarean section is performed with combined lumbar and rigid anesthesia, and due to the anesthesia method, it is necessary to stay in a flat position for 6 hours after the operation, and the anesthesia effect still exists at this time, and the mother’s lower limbs are restricted and her gastrointestinal motility is slow. Therefore, it is not advisable to use lap band at this time, otherwise it will affect the blood circulation of lower limbs and the recovery of gastrointestinal function. In about 24 hours after delivery, most women are able to ventilate, which means that the gastrointestinal function recovers, and the indwelling catheter can be removed to encourage patients to get out of bed and urinate on their own. At this time, you can start using a lap band, which can not only prevent the abdomen from sagging, but also protect the surgical incision. However, if the postoperative recovery is slow, the use of lap belts can be postponed. Be careful not to use too tight belly band, not only can not achieve the effect of body beauty, but also cause maternal discomfort, affecting the postpartum recovery, it is recommended to choose according to the maternal abdominal circumference.
