Abstract

Introduction: The hemodynamic response associated with laryngoscopy and tracheal intubation may be
harmful to certain patients. The laryngeal mask airway avoids the need for laryngoscopy in appropriate
patients.
Aims and Objectives: This study compares the changes in haemodynamic parameters in hypertensive
patients after laryngoscopic endotracheal intubation or laryngeal mask airway insertion.
Materials and Methods: 60 Hypertensive patients between 40 to 60 years ASA Grade II were randomly
allotted to one of the groups of 30 each, group ET and group LMA. LMA insertion or tracheal intubation
was performed after induction of anesthesia with Propofol and succinyl choline. The heart rate, mean
arterial pressure and rate pressure product were measured after induction and immediately after insertion /
intubation and then after 1, 3, 5 minutes.
Results: There was very highly significant difference (p < 0> in group ET versus 28.26% in group LMA). The increase in arterial pressure were also significant. The
systolic BP increased 40.16% in group ET compared with 37.60% in group LMA (p< 0> BP was also seen increasing by 22.73% and 14.23% in group ET and group LMA respectively. The MAP
and RPP values were maximum after airway instrumentation however we found that values after LMA
insertion were significantly lower when compared to tracheal intubation for the first 3 minutes.
Conclusion: LMA insertion in comparison to laryngoscopy and intubation is advantageous over tracheal
intubation in hypertensive patients avoidance of pressure response.
