title: [Randomized trail of nasal synchronized intermittent mandatory ventilation compared with nasal continuous positive airway pressure in preterm infants with respiratory distress syndrome].
abstract: OBJECTIVE
  To compare the efficacy of nasal synchronized intermittent mandatory ventilation (nSIMV) and nasal continuous positive airway pressure (nCPAP) in preterm infants with respiratory distress syndrome (RDS).
  
  
  METHODS
  Fifty preterm infants with RDS who received pulmonary surfactant were randomized to nSIMV and nCPAP groups after extubation. Clinical signs, symptoms and blood gas results following nSIMV or nCPAP were compared in the two groups.
  
  
  RESULTS
  Compared with the nCPAP group, the nSIMV group had a lower incidence of failure respiratory support (24% vs 60%; P<0.05), a lower incidence of hypercarbonia (12% vs 40%; P<0.05) and a lower incidence of hypoxia (24% vs 36%; P<0.05).
  
  
  CONCLUSIONS
  nSIMV is more effective in respiratory support in preterm infants with RDS.
