Efficacy of dexamethasone for lung maturity in preterm delivery in association with lamellar bodies count
Abstract
Background Organ immaturities in preterm infants may result inperinatal death. One of the diseases is respiratory distress syndrome
(RDS) which is caused by lung immaturity. Dexamethasone is often
used to accelerate maturity of infant lungs.
Objective To determine the efficacy of dexamethasone on lung
maturity measured by lamellar bodies count.
Methods A quasi experimental study was done at Perinatology
Division, Department of Child Health, Medical School, Udayana
University, Sanglah Hospital, Denpasar. We recruited 72 subjects;
36 subjects were given four times intramuscular dexamethasone
5 mg every twelve hours before delivery. Thirty six subjects who
did not receive dexamethasone belonged to control group. Infants’
lungs maturity assessment was performed using lamellar bodies
count taken from amniontic fluid.
Results The gestational age ranged between 28 to 36 weeks, with
the mean gestational age in dexamethasone group was 32.2 (SD
1.76) weeks and that in control group was 31.7 (SD 2.65) weeks.
The efficacy of dexamethasone therapy on lung maturity was
significant with Fisher’s exact test P<0.0001, 95%CI 2.546;
11.173. Using multivariate logistic regression analysis, there was
significant correlation between dexamethasone and lung maturity
measured by lamellar bodies count [OR=239.39; P<0.0001,
95%CI 22.12;526.53].
Conclusion Administration of dexamethasone in pregnant
women during preterm delivery significantly improves lung
maturity measured by lamellar bodies count.
