Abstract
PURPOSE
Surfactants have been used to improve oxygenation for infants with meconium aspiration syndrome (MAS). We evaluated the change of pulmonary indices after surfactant therapy for MAS through a systematic meta-analysis.
METHODS
Relevant randomized controlled studies (RCTs) were identified by database searches in MEDLINE, EMBASE, and CENTRAL, up to June 2011, and by additional hand searches. Data were extracted regarding pulmonary indices, such as the oxygen index and arterial alveolar oxygen gradient. Meta-analyses were separately conducted for the studies of surfactant lavage therapy and surfactant bolus therapy. The risk of bias was assessed, and clinical as well as statistical heterogeneities were also investigated.
RESULTS
Two RCTs for bolus surfactant therapy and two RCTs for surfactant lavage therapy were identified. The oxygenation index results were heterogeneous between the two studies in which bolus surfactant therapy was given, while a/A PO2 showed significantly better results in the treatment group over time after use of surfactant (12 hours: WMD 0.08, 95% CI 0.04-0.12; 24 hours: WMD 0.17, 95% CI 0.06-0.28). For surfactant lavage therapy, both studies consistently suggested an interventional benefit in terms of the pulmonary indices although it did not reach statistical significance.
CONCLUSION
Surfactant therapy appeared to improve oxygenation of infants with MAS. Since a limited number of RCTs are available in the current literature and those studies were also clinically heterogeneous in terms of illness severity and the method of surfactant use, further research is needed to gather evidence to support surfactant therapy in MAS.
