Antibiotics differ in their tendency to cause infusion phlebitis: a prospective observational study

Area of Science:

• Infectious Diseases
• Pharmacology
• Clinical Medicine

Background:

• Intravenous antibiotics are a known risk factor for infusion phlebitis.
• Previous research indicated varying cell toxicity among different antibiotics.
• Clinical observations suggested that antibiotics differ in their propensity to cause phlebitis.

Purpose of the Study:

• To prospectively evaluate the incidence of phlebitis associated with intravenous antibiotic use.
• To identify specific antibiotics that pose a higher risk for developing phlebitis.
• To explore other potential risk factors and protective elements influencing phlebitis development.

Main Methods:

• Prospective study involving 550 patients and 1386 peripheral venous catheters.
• Statistical analyses including univariate, multivariate, and Cox regression were employed.
• Incidence of phlebitis was compared between patients receiving antibiotics and those not.

Main Results:

• Overall phlebitis incidence was 18.5% with antibiotics versus 8.8% without (OR 2.34).
• Dicloxacillin (OR 5.74) and erythromycin (OR 5.33) demonstrated the highest phlebitis risk.
• Risk factors included insertion site and age (51-60 years); warfarin was protective, while low molecular weight heparin showed a non-significant reduction.

Conclusions:

• The hypothesis that different antibiotics vary in their tendency to cause phlebitis is confirmed.
• Specific antibiotics like dicloxacillin and erythromycin significantly increase phlebitis risk.
• Understanding these differences is crucial for optimizing patient care and minimizing infusion-related complications.
