METHOD FOR CARRYING OUT RADIAL ARTERY CATHETERIZATION Russian patent published in 2006 - IPC A61M25/01 A61B17/00 

FIELD: medicine.

SUBSTANCE: method involves making layer-by-layer incision in skin, subcutaneous fat and fascia in lower forearm part in radial artery projection. Catheter is set with three non-intersecting ligatures conducted under the radial artery. Then, the catheter is introduced into the artery. The catheter is fixed by means of a fixing ligature mounted thereon, passing under the artery and taking intermediate position relative to other insurance ligatures. Operation wound is sutured with insurance ligatures ends positioned proximally and distally relative to the fixing ligature, being brought out of the operation wound. Then, security ligatures ends, exiting from the wound, are temporarily fixed above the sutured wound and the catheter is withdrawn. The ends are to be released and removed after having removed the catheter. Before cutting fascia, it is to be additionally separated from the radial artery in particular cases as follows. The fascia is punctured with piercing surgical instrument having branches. The fascia is lifted a little by separating the branches and cut between the branches. It is advisable in particular cases to use catheter having tubular carrier inside. It is thought to be the best practice when catheter is introduced into the radial artery with carrier at an angle of 30-45° to longitudinal axis when placing the catheter. The catheter is moved farther into the artery in proximal direction with respect to the heart until blood emerges from carrier-having catheter end opposite to one introduced into the artery. Then the catheter is moved deeper in the same direction pushing it together with the carrier until its distal end penetrates 2-3 cm deep into the artery. Surgical suture material of 0.40-0.899 mm large diameter is applied as ligature in particular cases. It is recommendable to temporarily fix the security ligature ends brought out from the wound above the sutured wound by tying said ligature ends with temporary knot on members put beneath. Arterial hemorrhages taking place after removing catheter, repeated temporal fixation of said ligature ends exiting from the operation wound and released before withdrawing the catheter is thought to be the most effective above the sutured wound. The ends are to be released and removed after having accomplished final hemostasis. The repeated temporal fixation of said ligature ends above the sutured wound is said to come to optimum, if they are tied with temporary knot on members put beneath.

EFFECT: usage of radial artery for the transfusion operation purposes; avoided irreversible radial artery wall injuries; improved tissue repair and recovery conditions.
