Fig. 4From: Dexmedetomidine-ketamine versus Dexmedetomidine-midazolam-fentanyl for monitored anesthesia care during chemoport insertion: a Prospective Randomized StudyThe change of infusion rate of dexmedetomidine (μg/kg/h). Data are presented as mean ± SD. Group DK = dexmedetomidine-ketamine group; group DMF = dexmedetomidine-midazolam-fentanyl group, *: P < 0.05, compared with group DMF. †: P < 0.05, compared with baseline value, ‡: P < 0.05, compared with previous valueBack to article page
