Brief summary

The goal of this study is to determine if (H1) dexmedetomidine and midazolam are equally effective in reducing anxiety and stress response of surgical patients for elective cholecystectomy. 60 patients aged between 18 and 70, of ASA status I and II and BMI between 18 and 30 will be randomly allocated into dexmedetomidine and midazolam premedication group. Primary outcome will be a comparison of plasma ACTH level. Secondary outcomes will be a comparison of perioperative hemodynamic data, neutrphil/lymphocyte ratio, NPRS scores, and amount of drugs (opioids, induction agents, ephedrine) used.

Interventions

Intervention undertaken will be one application of 0.3 mcg/kg of dexmedetomidine in 100 mL of saline infused over 20 minutes (Subject group) as a premedication for patients undergoing elective laparoscopic cholecystectomy. Premedication will be applied by attending anaesthesiologists in a University Hospital Centre PACU. Adherence to intervention will be monitored using study data collection chart.
