Effects of Prednisolone and Dexamethasone in Children with Alkali Burns of the Oesophagus

Abstract We compared the efficacies of prednisolone and dexamethasone for treatment of children with oesophageal burns due to ingestion of caustic substances. The criteria of efficacy used were a) stricture severity by 3 weeks post-ingestion, b) reduction in burn severity by 3 weeks post-ingestion and c) number of dilatations required over the first year post-ingestion. Thirty-six children (24 boys and 12 girls; mean age 23.6 ± 7.4 months) were selected from a total of 63 patients admitted over a ten-year period to the General Hospital of Galicia with second-or third-degree oesophageal burns due to accidental ingestion of liquid alkali preparations. The patients were divided into two groups of 18, one group for treatment with prednisolone (2 mg/kg/day) and the other for treatment with dexamethasone (1 mg/kg/day). Strictures developed in 12 (66.7 %) of the children in the prednisolone-treated group and only 7 (38.9 %) of the children in the dexamethasone-treated group. Severe strictures developed in 10 (55.6 %) of the children in the prednisolone-treated group and only 5 (27.8 %) of the children in the dexamethasone-treated group. However, there was no significant difference between the groups in the post-treatment distribution of stricture-severity ratings. Burn healing was significantly better in the dexamethasone-treated group. Similarly, the number of dilatations necessary during the first year of treatment was significantly lower in the dexamethasone-treated group. Our results thus indicate that, by comparison with prednisolone, dexamethasone leads to improved burn healing and reduced need for dilatations during the first year post-injury.
