Abstract
Disclosed are methods and devices for obtaining patent hemostasis of the radial artery by compressing the uninstrumented ulnar artery to increase radial artery flow. The device comprises a band having an inflatable bladder for applying blunt pressure to the ulnar artery. The method comprises applying a pressure to the homolateral ulnar artery and applying a pressure to the radial artery at the access site to obtain hemostasis at the access site. The method further comprises administering an anticoagulant to a patient at a dose ranging from about 20 units per kg of body weight to about 30 units per kg of body weight.
Claims20
A method of obtaining patent hemostasis of a radial artery of a patient when performing a catheterization procedure at an access site of the radial artery, comprising performing the following steps:
- (a) administering a dose of anticoagulant to the patient during the catheterization procedure, wherein the dose of anticoagulant is less than an equivalent of 50 units of unfractionated heparin per kg of body weight;
- (b) applying a compressive pressure to the radial artery at the access site for a duration of time, wherein the duration of time is less than 120 minutes;
- (c) attaining patent hemostasis of the radial artery;
- wherein step (a) comprises administering anticoagulant at any time after introduction of a catheter or an introducer sheath and before removal of the catheter or the introducer sheath;
- and wherein step (b) comprises the compressive pressure to the radial artery being applied using a first band comprising at least a first inflatable bladder, the first inflatable bladder applying a compressive pressure to the radial artery at the access site.
A method of obtaining patent hemostasis of a radial artery of a patient when performing a catheterization procedure at an access site of the radial artery, comprising performing the following steps:
- (a) administering a dose of anticoagulant to the patient during the catheterization procedure, wherein the dose of anticoagulant is less than an equivalent of 50 units of unfractionated heparin per kg of body weight;
- (b) applying a compressive pressure to the radial artery at the access site for a duration of time, wherein the duration of time is less than 120 minutes;
- (c) monitoring and/or confirming patency of the radial artery, the step of monitoring and/or confirming patency of the radial artery being performed by sensing skin blood flow and/or pulsation at a fingertip or other location downstream of the access site;
- (d) attaining patent hemostasis of the radial artery;
- wherein step (a) comprises administering anticoagulant at any time after introduction of a catheter or an introducer sheath and before removal of the catheter or the introducer sheath;
- wherein step (b) comprises the compressive pressure to the radial artery being applied using a first band comprising at least a first inflatable bladder, the first inflatable bladder applying a compressive pressure to the radial artery at the access site;
- and
- wherein the compressive pressure to the radial artery in step (b) is gradually reduced and weaned off from the radial artery access site.
