Effects of propofol combined with ketamine intravenous anesthesia in pediatric surgery
The speech time.Table 1 the two groups in general condition and operation condition compared with 2.2 group two based anesthesia before MAP, HR, RR had no significant difference (P> 0.
05).Basal anesthesia after two groups of MAP, HR have increased, but not significantly (P> 0.05).Intravenous anesthesia after 1rain, K MAP, HR increased significantly (P< 0.01 or 0.05), RR had no obvious change; and group PK MAP, HR had no obvious change, RR was decreased significantly (P< 0.
05), compared with K group differences were highly significant (P< 0.01), but 5, 10min recovered to the level before anesthesia (P > 0.05).See table 2.Table 2 the two groups before and after anesthesia in MAP, HR, RR compared with the group of basal anesthesia before, a: T = 2.
616, ELT = 2.061, P < 0.05.b: P< t: 16.438, D: 0.01; t = 1.507, e: T = 0.685, P
