Background: One of the challenges for anaesthesiologists is to minimize distress for patients in the operating room (OR) environment and to facilitate a smooth induction of anesthesia.A sedative drug is given before transfer to the OR. The beneficial effects of anxiolytic are sedation, anxiolysis, reduction of postoperative vomiting andpostoperative emergence phenomenon. Clonidine, an α 2-agonist, have been suggested as another option for premedication as effective as midazolam.
Materials and Methods: 50 patients were randomly divided into two groups.To one group Tab. Midazolam 7.5 mg was given while to other group Tab. Clonidine 100 µg was given one hour before induction ofanesthesia.Patients were evaluated and compared for benefits of preoperative oral midazolam and oral clonidine on sedation scores, perioperative hemodynamic parameters and perioperative opioid and analgesic requirement. Independent sample t-test was used and p-value < 0.05 was considered significant.
Results: We found that mean OAA/S sedation score in clonidine group was 11.48 ± 1.12 than in midazolam group13.68 ±1.03withsignificant difference ofp value (p<0.001).There was significant (P < 0.05) attenuation of hemodynamic response to intubation, surgical stress response and extubation with clonidine as compared to midazolam .None of the patients desaturatedin either group. Opioid requirement(72%)was more in midazolam group as compared to clonidine (28%)group. Recovery in clonidine group took slightly longer time 60.00 ± 13.77min as compared to midazolam group 44.40±13.25 min.
Conclusion: Premedication with 100 micrograms of oral clonidine can reasonably be recommended as premedication in ASA I and II patients for all surgeries to provide more sedation, stable hemodynamics intraoperatively, reduction in stress response,less opioid consumption.
