Risk of Acute Kidney Injury with Amikacin versus Gentamycin both in Combination with Metronidazole for Surgical Prophylaxis

摘要

Introduction: Surgical site infection is one of the most important complication of surgery. It increases the mortality and morbidity. In order to decrease the incidence of surgical site infections perioperative antimicrobial prophylaxis has been recommended in certain types of clean and clean contaminated surgeries. Aminoglycosides are indicated as surgical prophylaxis for prevention of surgical site infection in patients with B-lactam allergy. Aim: The present study was carried out to study and compare the renal safety profile of single high dose gentamycin and amikacin as surgical prophylactic antibiotic. Materials and Methods: Prospective and randomized study was carried out on 100 patients for over one year period in a tertiary care teaching hospital of western Uttar Pradesh, India. Patients in amikacin group received amikacin 15 mg/kg + metronidazole 500 mg intravenously single dose and those in the gentamycin group had gentamycin 5 mg/kg + metronidazole 500 mg intravenously single dose, one hour prior to incision. Result: A total of 16% patients of amikacin group and 24% patients of gentamycin group developed acute kidney injury within one week of drug administration. The rise in serum creatinine was temporary as all patients had normal serum creatinine level at one month follow up. Conclusion: Aminoglycoside intravenous single high dose is not safe as surgical prophylaxis.
