Abstract
Central venous cannulation is associated with many complications. The recent literatures suggest that there is a close relationship between peripheral and central venous pressure readings. This quasi-experimental study is designed to investigate the agreement between central venous pressure (CVP) and peripheral venous pressure (PVP) and investigate the effect of intravenous catheter placement on the risk of complications in critically ill patients. Sixty patients were enrolled in the study as soon as they had a central venous catheter in place. They were cannulated at the antecubital site with a 20- gauge peripheral over- the needle intravenous catheter at the same time of central venous catheter insertion. Assessment of risk of complications of both peripheral and central venous catheters was done using the infiltration scale, observation of exit-site infection, assessment of catheter occlusion as well as bacteriological examination. Peripheral and central venous pressure readings were monitored immediately after insertion of both central and peripheral venous catheters and then every 6 hours for 3 days. Temperature and blood pressure were measured before each measurement. The results showed that PVP was closely correlated to CVP (r = 0.92 to 0.98). Significant relation was found between CVP and PVP at different times of measurement. PVP was consistently greater than CVP by an average of 2 mmHg. (P<0.001). Catheter colonization was significantly higher among patients with central venous catheters (CVCs) (P<0.01). Catheter malfunction was higher in CVCs. Infiltration occurred more often with peripheral venous catheters. The findings indicated that peripheral venous pressure can be used instead of central venous pressure for estimation of body volume status and minimize central catheter complications.
