Insights
Meconium aspiration (MA) in newborns does not appear to cause long-term lung problems. Preschoolers with MA experienced more coughing without colds, but lung function tests showed no significant differences compared to controls.
Area of Science:
- Pediatrics
- Pulmonology
- Neonatology
Context:
- Meconium aspiration syndrome (MAS) is a significant concern in neonatology.
- Previous studies on long-term outcomes of MAS have yielded inconsistent results.
- Understanding the pulmonary sequelae of MAS is crucial for clinical management.
Purpose:
- To investigate the long-term pulmonary development in children with a history of meconium aspiration.
- To compare lung function and respiratory symptoms in children with and without MAS.
- To identify any persistent pulmonary issues associated with meconium aspiration.
Summary:
- This study prospectively evaluated 25 children with meconium aspiration (MA) aged 1-11 years.
- Parents completed questionnaires, and children underwent physical examinations; older children (≥5 years) had spirometry, bodyplethysmography, and histamine provocation tests.
- Compared to 28 controls, children with MA showed no differences in history or physical exams, but preschool-aged children (1-5 years) reported "cough without cold" more frequently (p < 0.01).
- Lung function tests and histamine thresholds were similar between groups, indicating no long-term pulmonary sequelae.
Impact:
- This research suggests that meconium aspiration syndrome may not lead to significant long-term pulmonary deficits.
- The findings indicate that while transient symptoms like increased coughing may occur in early childhood, severe or persistent lung issues are unlikely.
- Provides reassurance for clinicians and parents regarding the pulmonary prognosis of infants with meconium aspiration.
Abstract:
The further development of newborns with meconium aspiration (MA) has been studied retrospectively by various investigators. However, results are inconsistent (2, 3, 5, 6). In the present study 25 children with MA were investigated in the age of 1 to 11 years. The parents answered a questionnaire, the children were examined physically. All the 11 children older than 5 years were subjected to spirometry, bodyplethysmography, and a histamine provocation test. An age matched control group of 28 children was investigated in the same way. No differences were found between children with MA and the control group concerning history and physical examination. Only the symptom "cough without cold" was found significantly more frequently in preschool children (1 to 5 years) with MA as compared to control children (p < 0.01). However, none of the parameters of lung function testing revealed any difference between the two groups. Also, the medians of the histamine thresholds in both samples were normal and did not differ. In summary, in a group of 25 children with MA, when compared to children without MA, only the symptom "cough without cold" was found significantly more frequently during preschool age. No evidence of long term pulmonary sequalae was seen in children with MA.
