title: Venipuncture vs. arterial catheter activated partial thromboplastin times in heparinized patients.
abstract: The use of arterial or venous access for obtaining a blood sample to determine the activated partial thromboplastin time (aPTT) remains controversial. The findings of this study indicate that only access site affects aPTT. Findings such as these can be used by critical care nurses to develop unit-based standards.
