Input: Two trials met the inclusion criteria. Faix 1988 randomised 42 premature infants with radiological diagnosis of NEC. Infants were randomised to receive either intravenous ampicillin and gentamicin or ampicillin, gentamicin and clindamycin. Hansen 1980 randomised 20 infants with NEC to receive intravenous ampicillin and gentamicin with or without enteral gentamicin. In the study by Faix 1988, there were no statistical differences in mortality (RR 1.10; 95% CI 0.32 to 3.83) or bowel perforation (RR 2.20; 95% CI 0.45 to 10.74) between the two groups although there was a trend towards higher rate of strictures in the group that received clindamycin (RR 7.20; 95% CI 0.97 to 53.36). The Hansen 1980 study showed no statistically significant difference in death, bowel perforation or development of strictures. There was insufficient evidence to recommend a particular antibiotic regimen for the treatment of NEC. There were concerns about adverse effects following the usage of clindamycin, related to the development of strictures. To address this issue a large randomised controlled trial needs to be performed.
Output:

The authors of this study reviewed the medical literature to ascertain the best antibiotic combination for the treatment of this condition. Four eligible studies were identified and only two of these studies were found to be suitable for analysis. Both these studies were performed before 1988. The two studies included 62 infants with NEC and compared one antibiotic regimen to another. There was no difference between the two groups. The authors concluded that there was insufficient evidence to recommend a particular antibiotic regimen for NEC.
