The Meta analysis showed that ambroxol administration significantly reduced the incidence of RDS (OR=0.24, 95%CI: 0.15 - 0.64, P<0.01), bronchopulmonary dysplasis (BPD, OR=0.41, 95%CI: 0.23 - 0.75, P<0.01), intraventricular hemorrhage (IVH, OR=0.39, 95%CI:0.24 - 0.64, P<0.01), patent ductus arteriosus (PDA, OR=0.33, 95%CI: 0.17 - 0.67, P<0.01) and pulmonary infection (OR=0.24, 95%CI:0.14 - 0.38, P<0.01). No adverse events related to the ambroxol treatment were reported.</p><p><b>CONCLUSIONS</b>The current evidence shows that early use of ambroxol can reduce the risk of RDS, BPD, IVH, PDA and pulmonary infection in preterm infants.</p>
