Abstract

Laryngoscopy and endotracheal intubation is the most commonly employed technique for the safe conduct
of general anesthesia. However both laryngoscopy and intubation are noxious stimuli that are associated
with hemodynamic responses in patients who are undergoing surgery under general anesthesia. Hence the
present study is to know the hemodynamic response to laryngoscopy and intubation with different induction
drugs which are used for general anesthesia.
90 patients of ASA class I and II, between 18-45yrs of age group, who were scheduled for various elective
surgeries under general anesthesia were randomly divided into 3 groups of 30 each (n=30).
Results: There was no much increase in the heart rate after induction and intubation (from 3rd minute
onwards in group P and group T, (p<0> statistically significant. The increase in MAP following induction and intubation was very minimal in group
P when compared to group T and it was still more less when compared to group E, which was statiscally
significant (P<0> Conclusion: Propofol is acceptable as an induction agent with stable haemodynamics for laryngoscopy
and intubation but, Etomidate is still a better choice for its haemodynamic stability over Propofol and
Thiopentone.
