NCT07338773

Brief Summary

he purpose of this study is to compare the effects of two different ways of giving the antibiotic vancomycin to prevent infections in patients undergoing amputation due to diabetic foot infection. Patients with diabetes often have poor blood circulation in their legs, which may prevent standard intravenous (IV) antibiotics from reaching the surgical site in high enough concentrations. This study compares: Intraosseous (IO) Administration: Giving the antibiotic directly into the bone at the amputation site during surgery. Intravenous (IV) Administration: Giving the antibiotic through a standard vein infusion before surgery. The researchers want to find out if the intraosseous method: Reduces the rate of surgical site infections compared to the standard IV method. Causes fewer changes in kidney function (measured by serum creatinine levels). Decreases the need for additional surgeries (reoperations) within 90 days. Patients will be randomly assigned to either the IO or IV group and will be followed for up to 90 days to evaluate their recovery and clinical outcomes

Outcome Measures

Primary Outcomes (1)

  • LOCAL AND SYSTEMIC VANCOMYCIN CONCENTRATIONS

    COMPARISON OF VANCOMYCIN CONCENTRATIONS (MCG/ML) MEASURED FROM THE SURGICAL SITE (LOCAL STUMP AREA) AND THE SYSTEMIC CIRCULATION (PERIPHERAL BLOOD). THE GOAL IS TO EVALUATE THE PHARMACOKINETIC EFFICIENCY OF INTRAOSSEOUS (IO) ADMINISTRATION VERSUS INTRAVENOUS (IV) ADMINISTRATION IN REACHING TARGET LEVELS AT THE AMPUTATION SITE IN PATIENTS WITH PERIPHERAL VASCULAR DISEASE.

    NTRAOPERATIVE (MEASURED DURING SURGERY, APPROXIMATELY 15-30 MINUTES AFTER DRUG ADMINISTRATION).

Secondary Outcomes (1)

  • REOPERATION RATE (RTOR)

    UP TO 30 DAYS POSTOPERATIVELY.

Study Arms (2)

Intraosseous Vancomycin

EXPERIMENTAL

500 mg Vancomycin hydrochloride dissolved in of %0.9 NaCl, administered directly into the intramedullary space.

Drug: Intraosseous Vancomycin

Intravenous Vancomycin

ACTIVE COMPARATOR

500 mg Vancomycin hydrochloride administered via peripheral intravenous infusion

Drug: Intravenous Vancomycin

Interventions

A single dose of 500 mg Vancomycin is administered into the bone marrow (intraosseous route) to achieve high local tissue concentrations at the surgical site.

Intraosseous Vancomycin

A single dose of 500 mg Vancomycin is administered via systemic intravenous infusion for standard prophylactic care.

Intravenous Vancomycin
