Reliability of Blood Cultures Collected from Intravascular Catheter Versus Venipuncture

摘要: This is a study of 130 matched venipuncture and intravascular blood cultures collected from 53 patients. In 99 (76.1%), both the catheter specimens were negative. There six yielding significant isolates: in three positive; two only specimen was one positive. Twenty-five positive only, 23 these classified as contaminated cultures. Thus, contamination rate significantly higher culture (P less than 0.001). These results indicate that should not be routinely catheters unless collection by impossible.
