Oximetry Guided Versus Traditional Rapid Deflation Technique for Achieving Hemostasis After Radial Procedures

"At the cath.lab. (Step 1) a hemostasis test is performed: oxymetry device on the thumb, compress a.ulnaris, evaluate if curve on device (=Patent hemostasis). If patent no further action. If not patent, air is deflated until a.radialis is patent (curve on device and no bleeding). If bleeding occurs before patency then re-inflate 1-2 ml. air until hemostasis (=no patent hemostasis). In patients with Patent hemostasis no action is taken in sixty minutes whereafter the TR-band is fully deflated (Step 2), and if bleeding then air is re-inflated until hemostasis and step 2 is repeated every 20 minutes until the TR-band is fully deflated with hemostasis. If no patent hemostasis at cath.lab. a hemostasis test is performed after 20 min. If patent hemostasis is achieved no action is taken in sixy minutes (as above). If still not patent then further action as in group A."
