右美托咪定联合硝酸甘油在腰椎手术控制性降压中的应用
目的探讨右美托咪定(DEX)联合硝酸甘油(NTG)用于腰椎手术控制性降压的效果。方法收集2012年1月至2014年6月该院收治的63例行腰椎手术患者。根据随机数字表法将所有患者分为NTG组(N组,31例)与DEX联合NTG组(ND组,32例)。在气管插管完成后,ND组给予DEX负荷剂量1.0μg/kg,10 min泵完,然后以0.5μg/(kg·h)泵至控制性降压结束,N组则泵入等量的生理盐水。两组均在行腰背筋膜切开时开始泵入NTG 1.0μg/(kg·min),调节泵入速度,使平均动脉压(MAP)较术前基础值下降30%。在缝合腰背筋膜前停用DEX与NTG。监测并记录麻醉诱导前(T0)与控制性...

| Summary: | 目的探讨右美托咪定(DEX)联合硝酸甘油(NTG)用于腰椎手术控制性降压的效果。方法收集2012年1月至2014年6月该院收治的63例行腰椎手术患者。根据随机数字表法将所有患者分为NTG组(N组,31例)与DEX联合NTG组(ND组,32例)。在气管插管完成后,ND组给予DEX负荷剂量1.0μg/kg,10 min泵完,然后以0.5μg/(kg·h)泵至控制性降压结束,N组则泵入等量的生理盐水。两组均在行腰背筋膜切开时开始泵入NTG 1.0μg/(kg·min),调节泵入速度,使平均动脉压(MAP)较术前基础值下降30%。在缝合腰背筋膜前停用DEX与NTG。监测并记录麻醉诱导前(T0)与控制性降压15 min(T1)、45 min(T2)、75 min(T3)及拔管后15 min(T4)的MAP、心率(HR)值。在T1、T2、T3时,由对所选药物不知情的骨科医生按照Fromme评分法进行手术视野质量评分。记录从用药开始至达到降压目标时的NTG用量与时间、停药后血压恢复至手术前水平的时间、术后拔管时间与躁动、呛咳反应情况。结果与T0比较,两组在T1、T2、T3时MAP明显降低;N组在T1、T2、T3时HR较ND组明显增快,差异均有统计学意义(P〈0.05)。ND组T1、T2、T3时Fromme评分明显低于N组,达到目标血压时间较短且NTG用量明显减少,差异均有统计学意义(P〈0.05)。在苏醒过程中,两组患者躁动、呛咳发生率比较,差异有统计学意义(P〈0.05)。结论 DEX联合NTG应用在腰椎手术中控制性降压安全有效,NTG用量明显减少,手术视野改善明显,明显减轻术毕患者拔管时的呛咳反应。 |

| Bibliography: | Objective To evaluate the efficacy of dexmedetomidine combined with nitroglycerin in controlled hypotension during lumbar vertebrae surgery. Methods A total of 63 patients with lumbar vertebrae surgery in this hospital from January2012 and June 2014 were admitted and divided into group NTG(group N,31 cases)and group DEX+NTG(group ND,32 cases)according to table of random number. The both groups were anesthetized and intubed with the same method. Group ND received1.0 μg/kg DEX with 10 min pump and then was followed by 0.5 μg/(kg·h)pump till finishing the controlled hypotension while group N with the same quantity of normal saline. The two groups were pumped NTG1.0 μg/(kg·min) when opening lumbodorsal fascia,adjusting the pumping speed,making the MAP reduced by 30% matching with the baseline before the operation. Dexmedetomidine and nitroglycerin were disused before suturing the fascia lumbodorsalis. The MAP and HR values were recorded at the time points of pre-induction(T0),15 min(T1),45 min(T2)and 75 min(T3) a |
