The anesthesia needle used for childbirth is about 10 cm long and 1-2 mm thick. If you choose to have a painless labor or a cesarean section, you will need an epidural or a combined lumbar and rigid anesthesia, and an anesthesia needle will be used. Anesthesia needles are instruments used to inject anesthetics and are slightly thicker than regular intramuscular needles, about 1-2 mm thick and 10 cm long. Before epidural anesthesia or combined lumbar and rigid anesthesia, a conventional fine-tipped injection needle is usually used to anesthetize the local skin, which will reduce the pain when the anesthetic needle enters. When injecting anesthesia, it is important to follow the doctor’s advice and choose an appropriate position, such as lying on the left side while curling up, to allow the anesthesia process to proceed smoothly. When using anesthesia needle the anesthetic is the medicine placed in the core of the needle, after the anesthetic is injected the doctor will promptly remove the needle, leaving only a thin flexible tube in the dural cavity to facilitate the subsequent continuous push into the anesthetic or analgesic and other operations. The anesthesia needle hole site should be kept clean and dry to avoid bacterial infection.
