title: LMA-ProSeal for elective postoperative care on the intensive care unit: a prospective, randomized trial.
abstract: BACKGROUND
  Compared to an endotracheal tube, laryngeal mask airways are known to cause less hemodynamic alteration during the extubation phase of routine perioperative airway management. This study aims to examine the hypothesis that the LMA-ProSeal (PLMA, The Laryngeal Mask Company Limited, St. Helier, Jersey, Channel Islands) is an adequate tool for elective postoperative care in the intensive care unit (ICU) and potentially associated with less hemodynamic alteration during extubation in the ICU environment compared to an endotracheal tube.
  
  
  METHODS
  Forty-eight patients were enrolled for this prospective randomized, controlled trial and were allocated to either control (ICU-T) or study group (ICU-P). In the ICU-P group, the endotracheal tube was replaced by a PLMA at the end of surgery.
  
  
  RESULTS
  Forty-patients completed the study. Cardiovascular parameters increased significantly less in the ICU-P group: systolic blood pressure increased by 18.10 +/- 5.57 mmHg versus 34.65 +/- 5.63 mmHg (P < 0.05), mean arterial blood pressure increased by 11.23 +/- 3.25 mmHg versus 22.65 +/- 3.36 mmHg (P < 0.05), and heart rate increased by 9.3 +/- 2.9 versus 12.9 +/- 2.2 min (P < 0.05). Ventilation via the PLMA during transfer from the operation room to the ICU as well as during ICU stay was successful and without any adverse events.
  
  
  CONCLUSIONS
  Removal of the PLMA after recovery from anesthesia was associated with less cardiovascular change compared to the endotracheal tube. Ventilation was possible without reported adverse events during the entire trial. Elective endotracheal tube replacement by the PLMA may be a useful procedure in selected patients.
