RESUMEN
Objective:To explore the effect of aerobic exercise combined with diet management on volume overload and cardiac function in patients with peritoneal dialysis.Methods:A total of 100 patients who received peritoneal dialysis in the Second Affiliated Hospital of Xi ′an Jiaotong University from August 2017 to March 2019 were recruited in the present study. Patients were randomly divided into intervention group and control group according to the random number table (50 cases in each group). The control group received routine nursing, while the intervention group carried out aerobic exercise combined with diet management on the basis of routine nursing. Before and after 6 months of intervention, the volume status, edema degree and cardiac function were compared between the two groups. Results:After 6 months of intervention, the levels of body weight, 24 h urine volume, 24 h ultrafiltration volume, systolic pressure, extracellular water, and extracellular water/total body water were (58.99 ± 7.30) kg, (366.41 ± 66.92) ml, (565.08 ± 102.24) ml, (142.64 ± 11.70) mmHg (1 mmHg=0.133 kPa), (12.30 ± 2.01) L, 0.39 ± 0.08 in the intervention group, significantly lower than in the control group (63.46 ± 12.90) kg, (431.90 ± 78.92) ml, (625.35 ± 91.31) ml, (150.11 ± 11.44) mmHg, (14.37 ± 4.12) L, 0.43 ± 0.07, the differences were statistically significant ( t values were 2.026-4.208, all P<0.05); the left ventricular ejection fractions, E/A were (61.38 ± 9.42)%, 1.15 ± 0.35 in the intervention group, significantly higher than in the control group (57.04 ± 7.83)% and 1.00 ± 0.29, the differences were statistically significant ( t values were 2.358, 2.113, all P<0.05). After 6 months of intervention, the normal ratio increased and Ⅲ grade ratio decreased in the intervention group, the difference of edema degree between the two groups was statistically significant ( Z value was 3.153, P<0.01). Conclusions:Aerobic exercise combined with diet management can effectively control the volume overload status and improve the cardiac function of patients with peritoneal dialysis.
