[Results before and after introduction of perioperative antibiotic prophylaxis in hip joint prostheses treatment of geriatric patients].

In a retrospective analysis the clinical history of 202 geriatric patients with vast morbidity who had received hip prosthesis were reviewed. The age of the patients at the time of operation was calculated to a mean of 82.9 years. Hundred and three cases who had underwent cefazolin application as an antibiotic prophylactic therapy were compared to 99 patients who had not received any antibiotics (control group). In comparison wound infections after surgery were less common among the cefazolin group (13.6%) than in the control group (26.3%). Additionally the incidences of reoperations, decubital ulcers and urinary tract infections were statistically significant lower in the cefazolin group as well.
