Factors Related to Autonomic Dysreflexia during Intermittent Catheterization in Patients with Spinal Cord Injury / 中国康复理论与实践

ABSTRACT

Objective:To investigate the occurrence and related factors of autonomic dysreflexia (AD) during intermittent catheterization in patients with spinal cord injury (SCI). Methods:Case control study was used in this study. Intermittent catheterization was performed on 44 SCI patients hospitalized from April, 2019 to April, 2020, The data of age, gender, time after injury, segment of injury, degree of injury, resting blood pressure, immediate blood pressure after catheterization, catheterization numbers, catheterization volume and duration of catheterization were collected. Descriptive analysis and binary Logistic regression analysis were used to analyze the occurrence and related factors of AD. Results:Totally, AD happened in 26 (59.1%) patients. Urethral catheterization was done 1738 times, out of which AD accounted for 187 times (10.8%). The risk of AD increased with the time after injury and age (P < 0.05). The probability of AD was lower in T7 SCI and below than in T6 SCI and above (P = 0.002). Catheterization numbers, gender, degree of injury, catheterization volume and duration of catheterization were not influencing factors of AD (P > 0.05). Conclusion:It is necessary to have a full understanding for the occurrence of AD in patients with SCI during intermittent catheterization. For patients with SCI in T6 and above, long time after injury and elderly patients, routine monitoring of blood pressure during intermittent catheterization is recommended to detect and deal with AD in time.
