Effect of different oral dosage of midazolam on anxiety before laparoscopic high ligation of the hernia sac in children with oblique inguinal hernia
Objective To observe the efficacy of different dosage of midazolam oral solution in re-lieving anxiety in children undergoing laparoscopic high ligation of the hernia sac with oblique inguinal her-nia.Methods A total of 120 children,93 males and 27 females,aged 2-6 years,78-120 cm in height and 11-25 kg in weight,ASA physical statusⅠ orⅡ,were selected to perform laparoscopic high ligation of inguinal oblique hernia sac under general anesthesia.According to random number table method,the chil-dren were divided into three groups:the oral midazolam 0.25 mg/kg group(group M1),0.5 mg/kg group(group M2),and 0.75 mg/kg group(group M3)30 minutes before anesthesia,40 children in each group.Modified Yale preoperative anxiety scale-short form(mYPAS-SF)was recorded at premedication,parental separation,and immediate induction of anesthesia.Induction compliance checklist(ICC)score,recovery time,extubation time,PACU residence time,pediatric anesthesia emergence delirium scale(PAED)and the modified face,legs,activity,cry and consolability scale(FLACC)30 minutes after operation were also recorded.Results Compared with before taking medication,mYPAS-SF scores in groups M2 and M3 at parental separation and immediate induction of anesthesia were significantly decreased(P＜0.05).Com-pared with group M1,mYPAS-SF scores at parental separation and immediate induction of anesthesia and ICC scores at immediate induction of anesthesia were significantly lower in groups M2 and M3(P＜0.05),the recovery time,extubation time and PACU resident time in groups M2 and M3 were significantly pro-longed,PAED score was decreased significantly within 30 minutes after operation(P＜0.05).Compared with group M2,the awakening time and extubation time in group M3 were significantly prolonged.(P＜0.05).Conclusion Oral midazolam 0.5 mg/kg or 0.75 mg/kg 30 minutes before anesthesia can effectively alleviate the preoperative anxiety of children,improve the degree of cooperation in anesthesia in-duction,and reduce the occurrence of postoperative agitation,the recovery time and extubation time pro-longed in children with oral midazolam 0.75 mg/kg.Therefore,an oral solution of midazolam 0.5 mg/kg was a more appropriate dose for preoperative antianxiety regimen in children.
