Venous pressure is a vital assessment parameter amongst critically ill patients. It can be monitored by inserting the central or peripheral venous catheter. the mean peripheral venous pressure during the three days was observed consistently higher than central venous pressure (11.5±2.5, 11.3±2.2, 10.8±4 vs 10.5 ± 2.1, 10.6± 2.04, 9.9± 3.70, respectively). For the prediction of connection, the equation used for reverting is CVP= .706 + 0.858* PVP and PVP= 1.559 + 0.936* CVP. The results showed no early complications from a central venous catheter and a peripheral venous catheter. Late complications findings demonstrate catheter occlusion for peripheral venous catheter (33%), followed by extravasation and infiltration grade 4 (28.4%). In comparison, the most common late complications from central venous catheters were catheter-related infections (5%). The results of the bacteriological examination showed that the three central venous catheters were positive. Two with gram-positive bacilli and one had gram-negative bacilli. The bacteriological examination for the peripheral venous catheter otherwise was negative. Conclusion and Recommendation: The researcher recommends using peripheral venous catheters for fewer complications than central venous catheters in the ICU and conducting further clinical trial research.
