Epidural Anesthesia

At that time, the most urgent technique for young anesthesiologists was not endotracheal intubation, arteriovenous puncture, nor ultrasonic nerve block, but epidural puncture anesthesia.

At that time, there were no puncture kits for lumbar anesthesia. Almost all operations, from the neck and chest to the abdomen and lower limbs, could be solved by epidural anesthesia. There is a small cold joke: a patient to undergo breast surgery and intestinal surgery, one of our teachers unexpectedly to the patient's spine from the top to the bottom of the three hard external tubes, in the corrie was known as "good news"!

Anesthesia epidural this technique, doctors should carefully to do local anesthesia to patients first, and then with a diameter of about 3 mm needle from the skin, subcutaneous, spine ligaments and spine, yellow ligament, ligament between all the piercing into the epidural space (namely the spine, epidural outside), and then in the originally closed group clearance into a thin tube, In order to keep pumping in the back. The local anesthetic, on the other hand, spreads up and down the epidural space, and also outward to the bilateral foramen and blocks several pairs of spinal nerve roots above and below the puncture site, thus exerting its anesthetic effect.
