Comparative study of cefoperazone and amikacin
Clinical Therapeutics
|January 1, 1984
Summary
Cefoperazone showed higher effectiveness than amikacin in treating severe surgical infections, particularly in biliary tract cases. Both antibiotics demonstrated good clinical responses, though further research is needed for mixed infections.
Area of Science:
- Infectious Diseases
- Surgical Infections
- Pharmacology
Background:
- Severe surgical infections pose significant clinical challenges.
- Antibiotic selection is critical for effective treatment and patient outcomes.
Purpose of the Study:
- To compare the efficacy and safety of cefoperazone and amikacin in patients with severe surgical infections.
- To evaluate the effectiveness of these antibiotics against specific types of infections and organisms.
Main Methods:
- A comparative study involving 60 patients with severe surgical infections.
- Patients were randomized into two groups, receiving either cefoperazone or amikacin for 5-10 days.
- Dosages were standardized: cefoperazone 2-4 gm/day, amikacin 900-1000 mg/day.
Main Results:
- Cefoperazone achieved a satisfactory clinical response in 83% of infections, compared to 74% for amikacin.
- Cefoperazone demonstrated superior efficacy in biliary tract infections.
- Bacteriological resistance rates were 7.5% for cefoperazone and 10% for amikacin. Failure rates in mixed infections were 29% for cefoperazone and 36% for amikacin.
Conclusions:
- Cefoperazone appears to be more effective than amikacin in severe surgical infections, especially biliary tract infections.
- Further clinical trials are recommended to elucidate the role of cefoperazone in treating anaerobic and mixed infections.
