Cesarean section anesthetic needle is a very thin puncture needle, usually ten centimeters long, with a cannula device, mainly for intrathecal anesthesia lumbar puncture use. Cesarean anesthesia is divided into intrathecal anesthesia and general anesthesia. 1. Intravertebral anesthesia: the most common type of anesthesia for cesarean delivery, the anesthesia time of this type of anesthesia can be decided according to the length of the operation. The anesthesiologist makes a puncture in the lumbar spine and pushes in the anesthesia drugs. Usually, a catheter is left in the epidural cavity of the mother’s body, and the catheter’s main function is to add drugs during the operation to ensure that the whole cesarean section operation is carried out smoothly. 2. General anesthesia: general anesthesia for pregnant women with contraindications to intrathecal anesthesia, once the general anesthesia pregnant women will enter a sleep state, because the general anesthesia is given by intravenous injection, these sedative, analgesic drugs may enter the fetal body through the placental bloodstream, resulting in respiratory depression of newborns, the time requirements of the operation is relatively high. The anesthetic injection for cesarean section is basically similar, and the choice of anesthesia is decided by a professional anesthesiologist after evaluation.
