title: [Experience with daily single dose administration of gentamicin].
abstract: The purpose of the study was to evaluate the effect and side-effects of once daily (OD) administration of gentamicin. The study was a retrospective analysis of patients treated with gentamicin OD for at least two days for proven or suspected infection. Of the 101 patients included, 60 were female, and the median age was 64 years (range: 20-90 years). Median duration of treatment was six days (2-63 days). All patients received combination therapy with two (36 patients), three (64 patients) or four (one patient) antibiotics, apart from gentamicin usually ampicillin, cefuroxime and/or metronidazole. Gentamicin doses were usually 240 mg on a fixed basis, but reduced in patients with pre-treatment impairment of serum-creatinine. Bacteriological cultures were taken in 90% of the patients, of which 59% were positive, most often with Enterobacteriaceae (57%) or other Gram-negative rods (11%). Effect of antibiotic treatment was seen in 82% of the patients. Nephrotoxicity defined as a 44 umol/l increase in serum-creatinine during treatment was found in five patients (5%). Ototoxicity, i.e. clinical signs of tinnitus, dizziness and/or impaired hearing, was reported in two patients. In conclusion, gentamicin OD with 240 mg is easy to administer, appears to be sufficient with regard to effect and has a low frequency of side-effects.
