A comparison of imipenem/cilastatin with the combination of cefuroxime and metronidazole in the treatment of intra-abdominal infections.

515 patients with intra-abdominal infection participated in an open randomized comparative multicenter trial in order to compare the efficacy, safety, and tolerance of imipenem/cilastatin with cefuroxime/metronidazole. 258 patients (mean age 56 years) received imipenem/cilastatin 1.5-2.0 g/day, and 257 patients (mean age 54 years) received cefuroxime 3.0-4.5 g/day plus metronidazole 1.0-1.5 g/day for at least 3 days. 130/161 evaluable patients (80.8%) receiving imipenem/cilastatin and 124/145 evaluable patients (85.5%) receiving cefuroxime/metronidazole were clinically cured. The microbiological response was favorable in 86.9% in the imipenem/cilastatin group and in 90.8% in the cefuroxime/metronidazole group. The two treatment groups were similar with respect to median time to defervescence which was 4 days. The median duration of treatment was 6 days and the median time to discharge from hospital was 9 days in both groups. Drug-related adverse reactions were observed in 14 patients receiving iminpenem/cilastatin and in 8 patients receiving cefuroxime/metronidazole. 19 patients in the imipenen/cilastatin group and 12 patients in the cefuroxime/metronidazole group died. No correlation was found between the deaths and the study drugs. The present study shows that intra-abdominal infections can be treated successfully with imipenem/cilastatin as well as with cefuroxime/metronidazole.

Comparison between sterile saline and tap water for the cleaning of acute traumatic soft tissue wounds.

OBJECTIVE: To find out if there were any differences in infection rates if acute traumatic soft tissue wounds were cleaned with tap water instead of sterile saline. DESIGN: Randomised study. SETTING: Emergency department at one city hospital. SUBJECTS: 705 consecutive patient with soft tissue wounds less than six hours old that did not penetrate a viscus, cavity, or joint and could be treated by primary suture. INTERVENTIONS: Randomly allocated to have the wound cleaned with either sterile saline or tap water in addition to debridement. MAIN OUTCOME MEASURE: Rate of wound infection, the presence of which was indicated by pus in the wound and prolonged healing. RESULTS: The infection rate in wounds cleaned with sterile saline was 10.3% compared with 5.4% in wounds cleaned with tap water (p less than 0.05). Infected wounds were significantly larger than uninfected ones (p less than 0.05) and more likely to be located on a lower extremity (p less than 0.05). There were no microbiological differences between the two groups, and no bacterial species grown from tap water was subsequently grown from an infected wound. CONCLUSION: Sterile saline should be replaced by tap water for the cleaning of acute traumatic superficial soft tissue wounds.
