Risk Factors for Phlebitis in Patients with Peripheral Intravenous Catheters

Introduction: The study investigated the risk factors of phlebitis associated with infusion by peripheral intravenous catheter (PIVC).

Methodology: Hospitalized adults (n = 506) were placed with PIVCs by trained nurses. Rates of phlebitis were noted according to PIVC gauge, insertion site, and dwell time; and type and volume of infusion solution.

Results: The development of phlebitis appeared to be significantly associated with the size of the outer diameter of the PIVC. The rate of phlebitis among patients given a hypertonic infusion solution was significantly higher; and also associated with infusion volume. There was no difference in phlebitis development among insertion sites, and dwell times among these sites were comparable.

Conclusion: The risk of phlebitis increased with the PIVC size and volume of infusion solution, and use of a hypertonic solution. The recognition of risk factors and standardized intervention may reduce the occurrence of phlebitis associated with PIVC use.
