Where is the painless needle for delivery?

At present, more and more people choose painless delivery. Painless delivery is an anesthetic needle injected into the mother's waist. Drugs are injected into the epidural space and released regularly. Anesthetics block sensory nerves, which has little effect on motor nerves. It can relieve pain without interfering with uterine contractions. This is an ideal situation. Most painless anesthesia will still interfere with uterine contractions to some extent and will prolong the labor period. Even if the labor period is prolonged, there is no bad effect on the fetal prognosis. Be careful not to penetrate the spinal meninges when painless. If the spinal meninges are pierced, the fetus will show intrauterine distress after anesthesia, and there will be certain problems in postpartum recovery.
