Abstract :

Hypertension and tachycardia usually accompany laryngoscopy and endotracheal intubation, which might be detrimental to patients with heart disease. The aim of the study was to determine the optimal time for injecting a low dose of Fentanyl (2µg / kg body wt) before intubation, for effectively attenuating the circulatory responses that accompanies laryngoscopy and intubation. This study was done in patients of both sexes in age group 20–50, posted for elective ENT surgeries planned under General Anaesthesia in a Tertiary care hospital . The patients were randomly assigned into four groups . Patients were given Inj Fentanyl 2µg / kg body wt either 1 minute, 5 minutes or 10 minutes before laryngoscopy and endotracheal intubation according to the group to which they were assigned. Patients in the control group received Inj.Pentazocine 500µg / kg body weight 5 minutes before intubation. The study showed that of all the four groups, Group III or the group where Inj Fentanyl 2 µg / kg body wt was given 5 minutes before intubation showed the maximum attenuation of the hemodynamic responses that accompany laryngoscopy and endotracheal intubation during anaesthetic induction. Also, the complications were found to be minimal in Group III compared to the other groups.
