80 ASA physical status I-II patients, 30-65 years, BMI ≤30 undergoing surgery for 120-180 minutes. Computer randomisation, 40 each, in dexmedetomidine group D and in propofol group P. Induction with fentanyl 1.5 mcg mkg−1 and propofol 2 mg kg−1. Maintained with desflurane 3-5% with air 50% and O2 50%. In D group (bolus 0.5 mcg mkg−1 for 10 minutes then maintenance 0.2-0.5 mcg mkg−1 hr−1) and in P group (propofol @ 50-150 mcg kg−1 min−1) started. At docking of robotic arms single dose morphine @ 0.075 mg kg−1 in both groups is given. Hemodynamic stability (MAP and HR) is adjusted within 20% of base line values.
Early and intermediate recovery was fast in D group and total fentanyl requirement intraoperatively was less in D group.
Dexmedetomidine is known to decrease sympathetic outflow and circulating catecholamine's levels therefore has caused decrease in both MAP and HR similar to propofol. Dexmedetomidine has analgesia sparing effect hence less total fentanyl dose both intraoperatively. Patients with dexmedetomidine are early aroused, so early and intermediate recoveries were faster with dexmedetomidine than propofol. Thus dexmedetomidine may prove to be useful adjuvant for robotic surgeries.
Dexmedetomidine more effective for both intraoperative and postoperative analgesia. Recoveries both early and intermediate are faster in dexmedetomidine group.
