There is insufficient evidence to support or refute the role of ambroxol in preventing neonatal respiratory distress syndrome in women at risk of pre-term birth. Further information is required regarding the benefits and risks of treatment.
This review found no evidence of benefit from cervical cerclage for preventing preterm birth in multiple pregnancy, and in women with cervical changes cerclage was associated with increased risks to the newborn.
Strategies to minimize post-caesarean section sepsis may contribute to reduction of maternal mortality and morbidity. This review found no significant differences between various types and methods of antiseptics, except very low quality evidence of reduced skin bacteria colony counts with chlorhexidine gluconate versus povidone-iodine. More research is needed.
