摘要
目的:探讨不同剂量右美托咪定滴鼻在神经定位刺激器引导下臂丛神经阻滞麻醉中的应用效果。方法:选取本院2019年1-10月拟行在神经定位刺激器引导下臂丛神经阻滞麻醉手术患者60例。按随机数字表法分为A组与B组,各30例。A组给予1.0μg/kg右美托咪定滴鼻,B组给予2.0μg/kg右美托咪定滴鼻。比较两组手术不同时间段血流动力学、镇痛评分与镇静分级(Ramsay);比较两组麻醉苏醒时间、镇痛持续时间、躁动评分(RS)及不良反应发生情况。结果:两组T0~T2时平均动脉压(MAP)、心率(HR)及血氧饱和度(SpO2)比较,差异均无统计学意义(P>0.05)。A组T3~T5时MAP、HR及SpO2均高于B组(P<0.05)。两组T0~T5时口述评分法(VRS)与Ramsay评分比较,差异均无统计学意义(P>0.05)。两组麻醉苏醒与镇痛持续时间比较,差异均无统计学意义(P>0.05)。A组RS评分低于B组(P<0.05)。A组并发症发生率为3.33%明显低于B组的23.33%(P<0.05)。结论:小剂量右美托咪定滴鼻在神经定位刺激器引导下臂丛神经阻滞麻醉中,可明显稳定患者血流动力学,在不影响镇静与镇痛效果下,有效减少并发症的发生,效果理想。
Objective:To investigate the effect of Dexmedetomidine nasal drip on brachial plexus block anesthesia guided by nerve location stimulator.Method:A total of 60 patients planed to undergoing brachial plexus block anesthesia under the guidance of nerve localization stimulator in our hospital from January to October 2019 were selected.According to the random number table method,they were divided into group A and group B,30 cases in each group.Group A was given nasal drip of 1.0μg/kg Dexmedetomidine and group B was given nasal drip of2.0μg/kg Dexmedetomidine.Hemodynamic,analgesia score and sedation score(Ramsay)were compared between the two groups at different operation time.The anaesthesia wake time,analgesia duration,restlessness score(RS)and adverse reactions were compared between the two groups.Result:There were no significant differences in mean arterial pressure(MAP),heart rate(HR)and blood oxygen saturation(SpO2)at T0-T2 between the two groups(P>0.05).MAP,HR and SpO2 at T3-T5 in group A were higher than those in group B(P<0.05).There were no significant differences in verbal rating scale(VRS)and Ramsay score at T0-T5 between the two groups(P>0.05).There were no significant differences in time of anesthesia recovery and analgesia duration between the two groups(P>0.05).The RS score of group A was lower than that of group B(P<0.05).The complication rate of group A was 3.33%significantly lower than 23.33%of group B(P<0.05).Conclusion:Low dose Dexmedetomidine nasal drops in brachial plexus block anesthesia guided by nerve location stimulator can significantly stabilize the patient’s hemodynamics,effectively reduce the occurrence of complications without affecting the sedation and analgesia effect and the effect is ideal.
