Comparative Evaluation of Haemodynamic Response to Conventional Tracheal Extubation and Removal of Classic Laryngeal Mask Airway (LMA-Classic) Following Bailey Manoeuvre: A Randomized Controlled Study
Haemodynamic Response to Tracheal Extubation and Removal of Classic LMA
Background: Exchanging 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 Classic LMA (CLMA) before endotracheal extubation versus conventional endotracheal extubation in ASA I patients scheduled for elective surgeries under general anaesthesia.Subjects and Methods:100 consenting adult patients were randomly allocated to two groups of fifty each; Group GET in whom extubation was performed using standard technique and Group GCL 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, SBP,DBP and MAP in Group GCL as compared to Group GET.Conclusion: Bailey manoeuvre IS A effective method to for attenuation of hemodynamic response to extubation.
