Randomized Controlled Trial Comparative Study Clinical Trial
Accuracy of drawing coagulation samples from heparinized arterial lines.
To determine the accuracy of activated partial thromboplastin time and prothrombin time studies when samples are drawn through heparinized arterial lines. ⋯ Results indicated that the minimal amount of discard volume for accurate activated partial thromboplastin time values in this population of percutaneous transluminal coronary angioplasty patients was the catheter deadspace volume plus 2 mL (total 3.6 mL).

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Evaluation of the effects of heparinized and nonheparinized flush solutions on the patency of arterial pressure monitoring lines: the AACN Thunder Project. By the American Association of Critical-Care Nurses.
To evaluate the effects of heparinized and nonheparinized flush solutions on the patency of arterial pressure monitoring lines. ⋯ Chances for patency are greatest in men with long femoral lines who receive other anticoagulants or thrombolytics and heparinized flush solutions. Risks of nonpatency are greatest in women with short nonfemoral lines who do not receive other anticoagulants or thrombolytics and have nonheparinized flush solutions.
