Abstract
Aim: The aim of the present study is to determine an optimal dose of IV dexmedetomidine by comparing different doses of the drug in terms of attenuation of haemodynamic stress response to laryngoscopy and endotracheal intubation.
Methods: This Randomized Double blind prospective clinical study was conducted at Sapthagiri Institute of Medical Sciences and Research Centre, Bengaluru, Karnataka for the period of 6 months. The sample size calculated in each group was 35.Group A: IV dexmedetomidine 0.3 μg/kg diluted to 20 ml with normal saline was given over 10 min.Group B: IV dexmedetomidine 0.5 μg/kg diluted to 20 ml with normal saline was given over 10 min.
Results: The mean age in group A and group B were 34.46±8.22 and 37.83±9.41 years respectively. 51.4% were males and 48.6% were females in both the groups. In both the groups, heart rate and SBP showed statistically significant result in 1 minute, 3 minutes and 5 minutes respectively.The sedation scores were more in Group B as compared to Group A.
Conclusion: The use of 0.5μg / kg dexmedetomidine as an intravenous infusion is associated with reduced postoperative pain and appropriate hemodynamic stability during surgery, and this dose seems to be effective in preventing acute postoperative pain.
