【摘要】 目的观察多发伤患者心率变异性变化及其临床意义。方法50例多发伤患者分为轻伤和重伤两组。分析伤后第2、9天24h心电图心率变异性。结果伤后第2天轻伤组SDNN(110.25±20.50ms)、SDANN(72.35±28.33ms)、SDNNIndex(51.37±17.37ms)较对照组显著降低(P<0.05),而RMSSD及PNN50与对照组无显著差异(P>0.05)。重伤组SDNN(85.30±30.21ms)、SDANN(68.41±27.52ms)、SDNNIndex(32.77±18.11ms)、RMSSD(20.81±10.31ms)及PNN5(05.41%±2.33%)均显著低于对照组(P<0.05)。伤后第9天,轻伤组与对照组无显著差异(P>0.05);重伤组SDNN(89.91±30.33ms)、SDANN(70.35±29.31ms)、SDNNIndex(43.88±20.31ms)、RMSSD(25.93±12.73ms)及PNN5(05.99%±3.55%)仍然显著低于对照组(P<0.05)。2周内心血管事件发生率重伤组(24.00%)显著高于轻伤组(4.00%)(P<0.05)。结论对多发伤患者作心率变异性检测,有助于了解自主神经功能变化,判断病情发展和预后。更多还原

【Abstract】 Objective To assess the change of heart rate variability(HRV)and it’s clinical significance in multiple trauma patients.Methods 50 multiple trauma patients were classified into mild injury(MI)and heavy injury(HI)groups.Ambulatory ECGs recorded the second and ninth day after injury were used for analyzing HRV.Results On the second day after injury, SDNN, SDANN and SDNN Index(110.25±20.50ms, 72.35±28.33ms, 51.37±17.37ms)but not RMSSD and PNN50 in MI group and all of them(85.30±30.21ms, 68.41±27.52ms, 32.77±18.11ms, 20.81±10.31ms, 5.41%± 2.33%)in HI group were significantly lower than those in control group(all P < 0.05).On the ninth day after injury, the parameters were still significantly lower in HI group(89.91±30.33ms, 70.35±29.31ms, 43.88±20.31ms, 25.93±12.73ms, 5.99%±3.55%), but not in MI group, than in control group(all P < 0.05).The incidence of cardiovascular events was significantly higher in HI group(24.00%)than in MI group(4.00%)during 2 weeks(P < 0.05).Conclusion Measurement of HRV may help understand autonomic nervous function and predict prognosis in multiple trauma patients.更多还原
