METHOD FOR SECURING THE EPIDURAL CATHETER AFTER PASSING THEREOF IN THE SUBCUTANEOUS CANAL Russian patent published in 2021 - IPC A61B17/34 A61M19/00 A61M5/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to anesthesiology and intensive care, and can be used for securing an epidural catheter by forming an intracutaneous loop and a cutaneous loop of the epidural catheter. A large subcutaneous canal is formed from the site of epidural access to the first exit of the epidural catheter to the skin. An epidural catheter is passed in the small subcutaneous canal by means of a modified spinal needle with an outer diameter of 0.52 mm or 0.45 mm, wherein said canal begins at a point located 5 mm lateral to the point of the first exit of the epidural catheter to the skin from the large subcutaneous canal. When forming the small subcutaneous canal, the modified spinal needle with the epidural catheter secured thereon is passed under the skin to a distance of 10 mm in the caudal direction, followed by passing the epidural catheter secured on the modified spinal needle into the lumen between the skin surface and the cutaneous section of the epidural catheter located on the skin surface between the point of the first exit of the epidural catheter to the skin and the point of entry of the epidural catheter into the small subcutaneous canal, thus forming an intracutaneous loop of the epidural catheter. The modified spinal needle with the epidural catheter secured thereon is then inserted into the lumen formed between the skin surface and the epidural catheter located between the point of the second exit of the epidural catheter to the skin and the point of entry of the epidural catheter into the small subcutaneous canal, thus forming a cutaneous loop of the epidural catheter. The two loops of the epidural catheter - the intracutaneous loop and the cutaneous loop - are therein formed after the epidural catheter is passed in the subcutaneous canal at the point of exit of the epidural catheter from the subcutaneous canal.

EFFECT: method ensures reliable securing of the epidural catheter, preventing external dislocation thereof, due to formation of loops.
