What is even a hard anesthetic needle
Oct 03, 2022
CONTINU EPIDURAL ANEASTHESIA (CEA), for short, involves piercing a needle into the EPIDURAL space from the back. Through the needle, a thin tube is inserted to inject local anesthetics to produce anesthesia in the lower body. This anesthesia eliminates the pain and temperature sensation of the patient. But it doesn't take away the sense of touch, and the patient can be awake during anesthesia.
As for postoperative analgesia, the epidural tube is kept for 48 hours after the operation and connected to an analgesic pump that can continuously administer drugs. At the same time, if the patient still feels pain at the knife edge, he can increase the dosage of the analgesic pump autonomously. Therefore, this mode is called PATIEN CONTROL ANEASTHESIA.
