Abstract:
Objective To observe the clinical effects of preoperative intranasal dexmedetomidine in pediatric anesthesia.Methods From April 2014 to April 2017,40 pediatric patients who accepted elective circumcision,ASA Ⅰ,aged 2 to 10 years in Wenjiang Branch of Sichan Provincial People's Hospital were divided into two groups,with 20 cases in each group.The test group received intranasal dexmedetomidine 1 μg/kg,and the control group received intranasal equal volume of saline 30 min before surgery.HR,SpO2,BP were monitored and recorded before intranasal (T0),5min after intranasal (T1),10min after intranasal (T2),20min after intranasal (T3),30min after intranasal (T4).The sedation score was assessed after 30 min of administration.The restless score was observed after waking.Results ANOVA analysis showed that there were significant differences in SBP (F =14.54,P ＜ 0.05) and DBP (F =22.69,P ＜ 0.05) between the two groups,and the SBP (F =13.77,P ＜ 0.05),DBP (F =10.48,P ＜ 0.05),HR(F =5.13,P ＜ 0.05) had interaction effects.Compared with those of the control group,the heart rate and the diastolic pressure of the test group were decreased at T2 ～ T4 (all P ＜ 0.05).The sedation score of the test group was superior than that of the control group(t =-9.131,P ＜0.05),and the postoperative agitation score was lower than that of the control group (t =3.387,P ＜ 0.05).Conclusion Intranasal dexmedetomidine can provide satisfactory sedative effects without affecting the vital signs of children and significantly reducing the postoperative agitation.
