Wheezy baby syndrome--a possible sequelae of neonatal meconium aspiration syndrome.

ABSTRACT

Forty children aged 5 months to 3 years and suffering from wheezy baby syndrome (WBS) were evaluated to find out the prevalence of neonatal meconium aspiration syndrome (MAS) from the birth records. Twelve (30%) babies with WBS were detected to have a history of MAS at birth, significant enough to require a neonatal ICU admission. In contrast, only 2% of the 50 control non wheezy babies aged 6 months-3 years had a history of neonatal meconium aspiration syndrome (p less than 0.001). There was no significant difference in mean number of wheezing spells over six months in the neonatal MAS positive and MAS negative groups (3.4 vs. 3.2, p greater than 0.05). Family history of atopy was present in 64.3% of wheezing subjects with normal birth records, while none had such history in babies with neonatal MAS. The results of the present study suggested an association between neonatal MAS and subsequent wheezing.
