术前心理干预对乳癌根治术患者焦虑及术后疼痛的影响

INFLUENCE OF PSYCHOLOY INTERFERING ON HEART RATE VARIABILITY BEFORE SURGERY AND PAIN AFTER SURGERY IN PATIENTS WITH BREAST CANCER

目的:了解乳腺癌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例乳腺癌手术患者分为干预组(43例)与对照组(42例)。对照组按常规手术准备及护理;干预组在常规手术准备及护理的基础上给予相应的心理干预。2组均于术前进行一次24h动态心电图(Holter)记录检测,测量焦虑值。记录术后疼痛分级情况。结果:术前干预组患者心率变异频域分析中低频带、低频带与高频带的比值明显低于对照组;高频带、总频带高于对照组;术前焦虑值与术后疼痛程度明显低于对照组。结论:乳腺癌手术患者术前给予心理干预,可使心率变异趋于平衡、减轻术前焦虑感从而减轻术后疼痛。

Objective： To realize the influence of pre-psychology interfering on heart rate variability （HRV） and pain after surgery in patients with breast cancer. Methods： 85 patients with breast cancer were divided into interfering group （43 cases） and control group （42 cases）. The patients in control group were given general preparative and nursing, but those in interfering group were added psycholoy interfering. Two group were the four indexes of frequency domain analysis and Self-Rating Anxiety Scale （SAS） were recorded before surgery,and recorded grade of pain after surgery. Results： Before surgery, LF and LF/HF in interfering group were lower than control group, HF and TF in interfering group were higher than those in control group; SAS score before surgery and pain degree was lower than those in control group. Conclusion： Psychology interfering can make HRV become balance and decrease anxiety before surgery, relieve pain after surgery in patients with breast cancer.
