Peripheral venous catheter-related inflammation. A randomized prospective trial

Area of Science:

• Medical research
• Infectious disease prevention
• Patient safety

Background:

• Peripheral venous catheter-related inflammation (PVCRI) poses significant health and economic burdens.
• PVCRI is primarily associated with the duration of peripheral venous catheter (PVC) use and other patient-specific risk factors.

Purpose of the Study:

• To prospectively evaluate the incidence of PVCRI based on PVC duration.
• To identify other risk factors, including age, gender, diabetes, and use of intravenous steroids and antibiotics, that may influence PVCRI.
• To compare the incidence of lymphangitis between PVC durations of 72 hours and 96 hours.

Main Methods:

• A prospective study involving 221 patients randomized to either 72-hour or 96-hour PVC duration.
• Data collection included patient demographics, comorbidities (diabetes), medication use (steroids, antibiotics), and inflammatory signs (fever, local inflammation).
• Statistical analysis utilized the Pearson chi-square test (alpha = 0.05) with Stata 8.0 software.

Main Results:

• PVCRI occurred in 20.4% of patients; incidence did not differ significantly between 72 and 96-hour durations.
• A significant increase in PVCRI incidence was observed with shorter durations (24 vs. 48 hours) and progressing from the first to the third day of catheterization.
• Age and intravenous antibiotic therapy were significant risk factors for PVCRI, while intravenous steroids showed a protective effect. Higher PVCRI rates were noted in the internal medicine/infectious diseases department.

Conclusions:

• Catheter duration beyond 72 hours up to 96 hours did not increase PVCRI risk.
• The risk of PVCRI appears to escalate from the first day to the third day of catheterization.
• Tailoring PVC duration to individual patient risk factors may offer a more cost-effective approach to preventing PVCRI.
