Single-dose dexamethasone treatment of hypotension preterm infants

Objective: To test the efficacy of single-dose dexamethasone (DXM) in the m anagement of severe arterial hypotension of newborn infants. Our hypothesis was that epinephrine infusions could be discontinued in 70% of patients wi thin 12 hours after DXM administration compared with 10% in the placebo gro up. Study design: Twenty preterm infants (median birth weight 690 g, gestationa l age 28 weeks, age at intervention 2 days) who did not respond to a standa rdized treatment protocol (blood/colloid followed by dopamine infusion step wise increased to 15 mu g/kg and minute) were started on an epinephrine inf usion and were randomly allocated to receive either DXM (0.25 mg/kg) or pla cebo intravenously. The primary outcome criterion was the need for an epine phrine infusion 12 hours after treatment. Results: Three infants were excluded. Epinephrine infusion was discontinued in 5 of 8 infants with DXM but in only 1 of 9 infants in the control group . The duration of epinephrine infusion was significantly shorter in the DXM group (exact log-rank test, P = .023). Conclusions: DXM was effective for the management of severe arterial hypote nsion in preterm infants not responding to standardized treatment.
