Objective To explore the applied effect of families synchronous health education on compliance with intermittent catheterization in patients with spinal cord injury and bladder voiding dysfunction. Methods A total of 60 patients with spinal cord injury caused bladder voiding dysfunction were randomly divided into observation group and control group in admitted chronological order. Patients in control group were given routine nursing; experimental group on the basis of conventional nursing, were applied families synchronous health education throughout the whole process of hospitalization and discharge follow-up. After 30 and 60 days′ self-intermittent catheterization, two groups′ urinary tract management of cognition, satisfaction, compliance and complications were observed and statistically analyzed. Results After 30 and 60 days′ self-intermittent catheterization, the observation group′ urinary tract management of cognition and satisfaction score were higher than those of the control group(P 0.05); the observation group′s properly adjusting time and correctly operation of urethral catheterization was higher than the control group(P 0.05); on the 60th day, the rate of cystolith and urinary mucosa bleeding of the observation group were lower than those of the control group(P 0.05). Conclusions Families synchronous health education actively, can improve the compliance of patients with intermittent catheterization and reduce related complications, thus improve the patients′ satisfaction.
