Group 1 received normal saline intravenously; group 2 received propofol (3 mg/kg IV) and dexmedetomidine (0.35 mg/kg IM); and group 3 received propofol (3 mg/kg IV) and ketamine (1 mg/kg IV). All values are expressed as mean ± SD.

^a–cValue is significantly (^aP < 0.05, ^bP < 0.01, ^cP < 0.001) from the baseline values (0 min) and compared with group 1 at the same time point.

^d,eValue is significantly (^dP < 0.05, ^eP < 0.001) different compared with group 2.
