title: Should aminoglycoside antibiotics be abandoned?
abstract: BACKGROUND
  Aminoglycosides can cause nephrotoxicity and ototoxicity. Alternatives are available.
  
  
  METHODS
  Surgical service antibiotic use, aminoglycoside toxicity, and perioperative culture/sensitivity results from July 1998 to June 1999 were reviewed.
  
  
  RESULTS
  Of 289 positive cultures in 243 patients, 92 cultures (32%) grew 151 Gram-negative rods (GNRs). Aminoglycosides were used in 26 patients and 4 of 26 (15%) suffered nephrotoxicity. Of the 112 GNRs tested against ceftazidime, 111 (99%) were sensitive to it which was significantly better than amikacin (56 of 61, 92%, P = 0.038), gentamicin (116 of 134, 87%, P <0.001), and tobramycin (67 of 81, 83%, P <0.001). The proportion sensitive to cefuroxime (26 of 30, 87%) was equivalent to the proportions sensitive to gentamicin (87%, P = NS) and tobramycin (83%, P = NS). Of the 35 GNRs that were resistant to gentamicin and/or tobramycin, 15 (43%) were Pseudomonas aeruginosa.
  
  
  CONCLUSIONS
  Aminoglycosides produce a significant rate of nephrotoxicity. There are antibiotics with equal or better sensitivity profiles than aminoglycosides against GNRs and Pseudomonas. Aminoglycoside use is rarely, if ever, indicated.
