Antibiotic Management After Neonatal Enteric Operations in US Children's Hospitals.

BACKGROUND

There are few evidence-based guidelines for perioperative antibiotic management in neonates who undergo enteric operations. We sought to assess antibiotic administration practices in a large population of patients who underwent operations involving enteric anastomoses and evaluate the incidence of postoperative infection and other outcomes based on antibiotic approach.

METHODS

The Pediatric Health Information Systems database was queried for patients who underwent repair of esophageal, duodenal or jejuno-ileal atresia in 2021. The type and number of consecutive days of perioperative antibiotics was determined and ICD-10 codes corresponding to infection were noted. The incidences of post operative infections (bacterial and fungal), antibiotic-resistant infections and anti-fungal medication administration were determined.

RESULTS

516 infants were identified. A wide variety of antibiotics were administered and 39 % of patients received more than one day of treatment. There were no differences in the incidence of postoperative infection between those who received more or less than one day of perioperative antibiotics for any of the operations assessed. The incidence of bacterial infection in patients treated with cefazolin or cefoxitin monotherapy was no different than that for all other regimens. There were no significant differences in the incidence of post-operative fungal infection based on antibiotic type or duration.

CONCLUSION

There was substantial variation in the duration and type of antibiotics administered after neonatal enteric operations. We identified a low incidence of infection with only one day of perioperative antibiotics and there was no evidence that longer treatment reduced infection risk. Cefazolin monotherapy was likewise associated with a low risk for perioperative infections.

STUDY TYPE: Non-interventional observational database study.
