title: [Risk factors associated to complications of the mechanical ventilatory assistance in the premature newborn].
abstract: OBJECTIVE
  To determine risk factors associated with the presence of complications with mechanical ventilatory support (MVS) in the preterm infants (PI).
  
  
  METHODS
  One hundred thirty medical records of PI that had been discharged by amelioration or death were reviewed retrospectively. They were divided in two groups: group A, PI that had presented complications during MVS (cases) and B, PI with MVS, but that had not presented complications due to the procedure (controls). Statistical significance was considered at p < 0.05.
  
  
  RESULTS
  The significative risk factors in the multivariate analysis reached significance for the associated of complications: gestational age (32 weeks or less), orotracheal reintubations three o more times, cycles of 60 per minute or more at the third day of being had initiate the MVS, and the symptomatic patent ductus arteriosus (PDA), all with p < 0.05.
  
  
  CONCLUSIONS
  It will be necessary to impact more on the cycles level to diminish him below 60 per minute to the third day when it is feasible, to make the smallest reintubations number, to correct quickly the PDA when it is symptomatic, to avoid this way as much as possible, the complications of the MVS.
