Abstract

Postural hypotension (PH) is a common clinical problem encountered in the rehabilitation of patients with spinal cord injury (SCI) above T6. The purpose of our study was to evaluate the effects of graded head-up tilting on common carotid blood flow volume (CCBFV), pulsatility index (PI), blood pressure (BP), and heart rate (HR) of patients with SCI and of healthy subjects.
Six patients with an SCI above T6 level and 15 healthy volunteers were recruited in our study. Their HR and BP at each tilt angle (0°, 30°, 45°, 60°, 75°) were recorded using a bedside monitor and personal computer, and their CCBFV and PI were determined by doppler ultrasound.
Patients showed significant decrease of CCBFV and systolic/diastolic BP, and significant increase of PI above a tilt angle of 45° and significant increase of HR above a tilt of angle 30°. For healthy subjects, we recorded significant increase of HR above a tilt angle of 45°, but little changes in CCBFV, systolic/diastolic BP, and PI with increasing tilt angle.
The results revealed changes in hemodynamic and physiological parameters of the SCI patients during graded head-up tilting and differences between SCI patients and healthy volunteers. These findings may provide more information for further study to improve the treatment of the SCI patients with PH.
