目的:采用超声联合心电图比较常规血液透析和维持性血液透析对尿毒症患者心脏结构及功能影响。方法:选取2014年2月至2014年11月我院收治的尿毒症患者110例,将其随机分为实验组和对照组,每组各55例。对照组予常规血液透析,实验组予维持性血液透析,采用碳酸氢盐透析液,透析液流量500-600 m L/min,每周透析2-3次,每次透析4h。治疗后,通过超声心动图测定室间隔厚度、左心室壁厚度、左心室舒张末内径、射血分数,采用心电图Q-T离散度分析Q-T离散度。结果:1治疗后,与对照组相比较,实验组患者EF、FS均显著降低,差异具有统计学意义(P<0.05),LVDd、LVDs、LVMI、LVH值均明显升高,差异具有统计学意义(P<0.05)。2治疗后,维持性血液透析患者的心电图Q-T离散度与对照组相比较,差异有统计学意义(P<0.05)。结论:维持性血液透析较常规血液透析能够更有效地改善尿毒症患者的心脏结构及功能。
Objective: To compare the effects of routine hemodialysis and maintenance hemodialysis on cardiac structure and function in patients with uremia by ultrasonography and electrocardiogram. Methods: A total of 110 uremic patients admitted to our hospital from February 2014 to November 2014 were randomly divided into experimental group and control group, with 55 cases in each group. The control group was given routine hemodialysis. The experimental group was given maintenance hemodialysis. Bicarbonate dialysate was used. The dialysate flow rate was 500-600 m L / min. Dialysis was performed 2-3 times a week for 4 hours. After treatment, the thickness of the interventricular septum, the thickness of the left ventricle, the end-diastolic diameter of the left ventricle and the ejection fraction were determined by echocardiography, and the Q-T dispersion was analyzed by electrocardiogram Q-T dispersion. Results: After treatment, compared with the control group, the EF and FS of the experimental group were significantly decreased, the difference was statistically significant (P <0.05), LVDd, LVDs, LVMI, LVH values were significantly increased, the difference was statistically significant Significance (P <0.05). 2 after treatment, maintenance hemodialysis patients ECG Q-T dispersion compared with the control group, the difference was statistically significant (P <0.05). Conclusion: Maintenance hemodialysis can improve the heart structure and function of uremic patients more effectively than conventional hemodialysis.
