Abstract
Background: prematurity is observed in 5-8 % of deliveries, and is frequent cause of handicap. Prema ture have 5-24 % risk for developing periventricular leukomalacia (PLM). The use of antenatal steroids (AS) is controversial for preventing PLM.
Methods: we studied 110 premature neonates < 1500g, divided in 2 groups: control (group 1, n = 55), and group 2 (n = 55) who received antenatal dexamethasone. We registered clinical data, evolution and use of oxygen or mechanical ventilation. At one month age a transfontanelar ultrasound was done looking specific PLM.
Results: in group 1, found 6/55 (10.9 %) with PLM and 3/55 (5.4 %) in group 2, RR = 0.5, CI 95 % (0.13-1.90). In group 1: 30/55 (54.54 %) the ultrasound was normal; in 16 (29 %) had intraventricular haemorrhage, and in 3 cases (5.45 %) had severe hydrocephalus. In group 2: 32/55 (58.18 %) ultrasound was normal, 16/55 (29 %) had intraventricular haemorrhage, 4/55 (7.27 %) had severe hydrocephalus. We did not find significant difference between other variables in both groups.
Conclusions: there was no significant differencein PLM incidence between patients who did or did not received antenatal dexamethasone, neverthless protection was observed in the group that received dexamethasone.
