Is the epidural needle painless

The epidural anesthesia needle uses a thick needle, so the pain is relatively large. In addition, the puncture depth is about 5-7cm, so local anesthesia is required during the puncture, otherwise the patient will feel very uncomfortable. Even after anesthesia in the process of puncture will feel acid swelling, but usually comfort patients, this needle than other needle acid swelling degree will be heavier, and try not to let the patient see the puncture needle before puncture, otherwise it will increase the psychological burden of patients. And some patients individual difference is relatively large, tolerance, psychological capacity is relatively poor, acceptance is relatively low. However, local anesthesia is usually performed during the puncture time, which is basically performed without pain.
