Concurrent use of indomethacin and dexamethasone increases the risk of spontaneous intestinal perforation in very low birth weight neonates.

Abstract

BACKGROUND:

Dexamethasone or indomethacin predisposes very low birth weight (VLBW) neonates to spontaneous intestinal perforation (SIP). However, no study has specifically investigated the role of the concurrent use of indomethacin and dexamethasone in SIP.

OBJECTIVE:

To test whether the concurrent use of indomethacin and dexamethasone increases the risk of SIP.

METHODS:

In this single center, retrospective, 2:1 matched, case-control study, the odds of SIP were assessed using univariate and multivariate logistic regression analysis in < or =14-day old VLBW infants.

RESULTS:

Sixteen VLBW infants with SIP were matched to 32 controls by birth weight. After adjusting for clinically relevant variables, patients who received > or =3 doses of indomethacin for ductal closure or intraventricular hemorrhage prophylaxis and > or =3 doses of low-dose dexamethasone (0.3 mg/kg cumulative dose over 3 days) for refractory hypotension during the first postnatal week, were 9.6 times more likely to develop SIP [95% CI 1.22, 75.71].

CONCLUSIONS:

The combined use of indomethacin and dexamethasone increases the risk of SIP in VLBW neonates.
