围手术期心理干预对心率变异性及疼痛耐受的影响

目的了解普外科患者术前心理干预对心率变异性及术后疼痛的影响。方法随机将85例普外择期手术患者分为心理干预组(43例)与对照组(42例)。对照组按常规术前准备及护理,心理干预组给予相应的心理干预,记录频域分析的四项指标。记录术后2、6、24h疼痛视觉模拟评分(VAS)。结果心理干预组患者心率变异频域分析低频带(LF)、低频带与高频带的比值(LF/HF)明显低于对照组(P<0.05或P<0.01);HF、总频带(TP)高于对照组(P<0.01);术后6、24h疼痛VAS明显低于对照组(P<0.01)。结论患者术前给予心理干预,可使心率变异趋于平衡,减轻焦虑,从而减轻术后疼痛。

Perioperative influence of psychological interfering on heart rate variability and pain

Objective To study the influence of psychological interfering and pain after on heart rate variability(HRV)in patients undergoing general surgery.Methods Eighty-five patients were divided into psycholoy interfering group(group P,43 cases)and control group(group C,42 cases).Before surgery,patients in group P were given genernal preoperative psychological and nursing preparation,but those in group C were not.HRV was analyzed and VAS scores were recoeded at 2,6 and 24 h after operation.Results Before surgery,LF and LF/HF were significantly lower and HF and TF were higher in group P than those in group C(P<0.05 or P<0.01).After surgery,VAS scores(6 and 24 h)were lower in group P than those in group C(P<0.01).Conclusion Psychological interfering can make HRV balanced before surgery,and decrease pain torerence after surgery patients undergoing general surgery.
