title: Comparative assessment of ProSeal™ laryngeal mask airway intervention versus standard technique of endotracheal extubation for attenuation of pressor response in controlled hypertensive patients.
abstract: OBJECTIVE
  Swapping of the endotracheal tube with laryngeal mask airway (LMA) before emergence from anaesthesia is one of the methods employed for attenuation of pressor response at extubation. We decided to compare the placement of ProSeal™ LMA (PLMA) before endotracheal extubation versus conventional endotracheal extubation in controlled hypertensive patients scheduled for elective surgeries under general anaesthesia.
  
  
  METHODS
  Sixty consenting adult patients were randomly allocated to two groups of thirty each; Group E in whom extubation was performed using standard technique and Group P in whom PLMA was inserted before endotracheal extubation (Bailey manoeuvre). The primary outcome parameter was heart rate (HR). The secondary outcomes were systolic, diastolic and mean blood pressure (MBP), electrocardiogram, oxygen saturation and end-tidal carbon dioxide. Two-tailed paired Student's t-test was used for comparison between the two study groups. The value of P < 0.05 was considered as statistically significant.
  
  
  RESULTS
  The patient characteristics, demographic data and surgical procedures were comparable in the two groups. A statistically significant decrease was observed in HR in Group P as compared to Group E. Secondary outcomes such as systolic, diastolic and MBP depicted a statistically insignificant difference.
  
  
  CONCLUSIONS
  Bailey manoeuvre was not effective method to be completely relied upon during extubation when compared to standard extubation.
