Abstract
Objective To study dexmedetomidine on the adverse impact of ketamine based anesthesia and sedative effects in indirect inguinal hemia.Methods Eighty children underwent indirect inguinal hemia surgery were randomily divided into two groups after injected muscle with midazolam and ketamine,Group B was injectded with 0.5 μg/kg DEX,but Group A with normal saline,analgesia was with caudal block (lidocaine).The with hemodynamic,level of sedation,recovery time and CHW score were observed.The adverse reactions were recorded.Results Two groups of children have hemodynamically stable,and recovery time had no statistical significance.The two groups of CHW score in Group A (1.6 ± 0.5) points higher than in group B (0.9 ± 0.3) points (P ＜ 0.05).The restlessness rated group (1.52 ± 0.54) points was higher than in group B (0.51 ± 0.48) points (P ＜ 0.05).Compared with Group B,Group A had 12 cases of psychiatric symptoms,10 cases of involuntary movement of limbs,6 cases of severe postoperative agitation nausea,and 8 cases of vomiting (P ＜ 0.05).Conclusion 0.5μg/kg DEX can be safely and effectively used in the pediatric anesthesia,and reduce the adverse reactions caused by ketamine.
