摘要
目的:研究右美托咪定用于心功能不全患者镇静的安全性。方法选取择期行心脏外科手术合并心功能不全的患者40例,按随机数字表法分为2组:Ⅰ组(右美托咪定组),0.5μg/kg右美托咪定10 min缓慢静点;Ⅱ组(对照组),同等剂量生理盐水缓慢静点。观察给药后10、20、30 min患者收缩压( SBP)、舒张压( DBP)、心率( HR)、血氧饱和度( SpO2)、脑电双频指数(BIS)值。给药5 min进行桡动脉动脉穿刺和中心静脉穿刺,同时监测心输出量(CO)、每搏量变异度(SVV),记录动脉穿刺、中心静脉穿刺后即刻SBP、DBP、HR、CO、SVV,以及给药后30 min CO、SVV。并且在给药30 min时进行镇静及疼痛评分。结果给药后10、20、30 minⅠ组SBP、DBP、HR、BIS值低于Ⅱ组( P <0.05);Ⅰ组动脉穿刺后即刻及中心静脉穿刺后即刻SBP[(124.9±15.5)mmHg vs (138.7±17.8)mmHg;(128.9±17.8)mmHg vs (140.3±19.3)mmHg, P <0.05]、DBP [(69.4±10.2)mmHg vs (80.1±11.2)mmHg;(70.5±11.8)mmHg vs (87.7±13.6)mmHg, P <0.05]、HR[(65.3±9.4)次/min vs (78.8±10.9)次/min;(68.2±10.8)次/min vs (80.9±13.3)次/min, P <0.05]、BIS(84.5±5.7 vs 95.4±3.7;87.8±7.7 vs 95.3±4.7, P <0.05)低于Ⅱ组( P <0.05),CO、SVV两组比较差异无统计学意义( P >0.05);Ⅰ组中心静脉穿刺后即刻及给药后30 min镇静评分高于Ⅱ组(3.4±1.5 vs 1.2±0.4;3.9±1.7 vs 1.4±0.5, P <0.05),疼痛评分低于Ⅱ组(2.1±0.7 vs 3.8±2.1;1.9±1.5 vs 4.1±2.1, P <0.05)。 SpO2各组比较差异无统计学意义( P >0.05)。结论0.5μg/kg负荷量右美托咪定可以安全的应用于心功能不全患者的镇痛、镇静。
Objective To investigate the safety of the application of dexmedetomidine in patients with heart failure .Methods The selective cardiac surgery 80 patients with heart failure were randomly divided into two groups ( n =20 each):group I:0.5 μg/kg dexmedetomidine intravenous injection in 10 min;and group II:control group.Systolic blood pressure (SBP), diastolic blood pres-sure (DBP), heart rate (HR), oxygen saturation (SpO2), and bispectral index (BIS) were recorded at 10, 20, 30 min after injec-tion.Cardiac output (CO) and stroke volume variation (SVV) were also recorded at the time after radial artery and internal jugular vein puncture , and Ramsay and visual analogue scale ( VAS) score were also given to each patients of two groups at 30 min.Results The SBP, DBP, HR, and BIS of group I were lower than group II at 10 and 20 min after injection ( P 〈0.05 ); the SBP, DBP, HR, and BIS of group I were also lower than group II at the time after radial artery and internal jugular vein puncture [ SBP:(124.9 ± 15.5)mmHg vs (138.7 ±17.8)mmHg;(128.9 ±17.8)mmHg vs (140.3 ±19.3)mmHg, P 〈0.05;DBP:(69.4 ±10.2)mmHg vs (80.1 ±11.2)mmHg;(70.5 ±11.8)mmHg vs (87.7 ±13.6)mmHg, P 〈0.05;HR:(65.3 ±9.4)bpm vs (78.8 ±10.9)bpm;(68.2 ±10.8)bpm vs (80.9 ±13.3)bpm, P 〈0.05;BIS:84.5 ±5.7 vs 95.4 ±3.7;87.8 ±7.7 vs 95.3 ±4.7, P 〈0.05]; The CO, SVV, and SpO2 were no difference between two groups;the Ramsay(3.4 ±1.5 vs 1.2 ±0.4;3.9 ±1.7 vs 1.4 ±0.5) and VAS (2.1 ±0.7 vs 3.8 ±2.1;1.9 ±1.5 vs 4.1 ±2.1)score of group I were lower than group II ( P 〈0.05).Conclusions A amount (0.5 μg/kg) of dexmedetomidine intravenous injection can be safely used in patients with heart failure .
