Abstract
Objective To analyze the effect of dexmedetomidine on restlessness during anesthesia recovery period after pediatric laparoscopic hernia surgery.Methods 82 children scheduled for laparoscopic hernia surgery were selected,the experimental group received intravenous pumping of 0.5μg/kg of dexmedetomidine and normal saline 20 ml at 10 min before anesthesia induction,while the conventional group received intravenous pumping of equal volume of normal saline.Observed the restlessness during anesthesia recovery period of the two groups,anesthesia and postoperative condition,changes of HR and MAP.Results The levels of HR and MAP at T1,T2 and T3 in the experimental group were lower than those in the conventional group (P＜0.05).The rate of restlessness during anesthesia recovery period in the experimental group was 12.20％,the duration of restlessness was (7.65±1.63)min,the score of restlessness was (1.55±0.65) points,the sedation score was (2.10±0.78) points,which were significantly superior to the conventional group (x 2=10.212 2,t=8.361 3,t=6.833 1,t=5.459 9;P＜0.05).There were no statistically significant differences in extubation time and anesthesia recovery time between the two groups (P＞0.05).The incidence of respiratory adverse events in the experimental group was significantly lower than that in the conventional group (9.76％ vs.34.15％;x 2=4.969 7,P=0.026 0).Conclusion In pediatric laparoscopic hernia surgery,pump injection of dexmedetomidine can effectively reduce the incidence of restlessness during anesthesia recovery period and the incidence of respiratory adverse events,with smooth anesthesia process and remarkable sedative effect.关键词
