title: [Noninvasive positive pressure ventilation in postoperative period of tracheal surgery].
abstract: OBJECTIVE
  Reconstructive surgery of the airway often means prolonged periods of intubation during the post-operatory period, increasing the needs for drugs and favoring the appearance of infectious complications. We present an original system of ventilatory support with non-invasive positive pressure ventilation (NIPPV) using in patients subjected to reconstructive surgery of the airway.
  
  
  METHODS
  A retrospective study in patients undergoing reconstructive procedures of the airway in the year 2009 was carried out. We exclude those treated endoscopically and those who had vascular rings. The positive pressure mechanism used in the Surgery Critical Care Unit was a design made by the unit based on the circuit devised by Mapleson that provides optimum levels of ventilation without need for connection to a respiratory. We analyze the results, postoperatory intubation time, time dependent on NIPPV and medical treatment received.
  
  
  RESULTS
  A total of 7 patients (1 Female and 6 Males) with median age of 1.6 (0.1-7.5) years were included. The diagnoses were: 4 subglottic stenosis, 2 had tracheal stenosis and 1 subcarinal stenosis with involvement of both principal bronchioles. The techniques used were: laryngotracheoplasty with costal cartilage graft (4), tracheoplasty with costal cartilage (1) and sliding tracheoplasty (2) with bilateral bronchoplasty in one of them. The mean time of nasotracheal intubation was 3 days, and mean time of NIPPV was 2.3. No patient required reintubation and none had infectious complications.
  
  
  CONCLUSIONS
  Ventilatory support by VPPNI allows effective extubation in these patients, it being possible to maintain a safe airway. Infectious complications, frequent in prolonged intubations, were not observed in any of the cases.
