SUBSTANCE: invention relates to medicine, to anesthesiology and reanimatology. Epidural puncture is carried out, a catheter is introduced into the epidural space in the direction of the head, with introduction of a drug through it.

Straight pipe of the three-way cock is muffled with the locking IN-stopper, through the rubber membrane of which the catheter is introduced into the lumen of the epidural needle and push it beyond the needle tip toward the head for a distance of 4–5 cm inside the epidural space. Syringe with a saline solution is injected into the epidural catheter, and a syringe with a local anesthetic solution is slowly for 3 minutes injected into the side pipe of the three-way cock synchronously with introduction of the local anesthetic through the lumen of the epidural needle and physiological solution is injected through the catheter.
