| Abstract: | The purpose of this study was to compare blood coagulation values drawn by venipuncture and from an intraarterial catheter. A 10 ml discard was obtained from 50 consecutive patients before obtaining the coagulation sample from the intraarterial catheter, and a 0.5 ml discard was obtained from the venipuncture specimen. A two-tailed t test for related samples was performed. The results revealed no significant difference between the two methods (p>0.05). The small differences seen were attributed to sampling error. These results suggest that blood samples obtained from heparinized intraarterial catheters after a 10 ml discard provide an accurate assessment of patients' mean clotting time. |
