title: [Ventilation using the laryngeal mask and intubation tube during general anesthesia for ophthalmic surgery].
abstract: OBJECTIVE
  The aim of the investigation was to compare efficacy of using for airway maintainance and controlled ventilation the laryngeal mask versus orotracheal intubation.
  
  
  METHODS
  We carried outs this examination in the group of 50 patient of both sex scheduled for elective operations in ophthalmic surgery. All participants were of I or II class of perioperative risk according to ASA scale. We tried to estimate efficacy of using laryngeal mask versus orotracheal intubation during anaesthesia with controlled ventilation. We examined capillary blood hemoglobin saturation, carbon dioxide pressure in end-tidal expired gas and peak inspiratory pressure while laryngeal mask or orotracheal tube was applied.
  
  
  RESULTS
  We found no differences of clinical importance in both group of patients in the range of measured parameters.
  
  
  CONCLUSIONS
  We conclude that ventilation with the laryngeal mask inserted is safe and effective providing that patients are carefully selected.
