ABSTRACT
Patients with a spinal cord injury above the 6th thoracic vertebrae may be prone to autonomic dysreflexia (AD) in response to bladder stimulus associated with a urodynamics investigation. It is essential that these patients are managed carefully in the urodynamics clinic in order to prevent life-threatening hypertension and bradycardia. Part of this management is the measurement and manual recording of pulse rate (PR) and non-invasive blood pressure (NIBP), alongside the standard urodynamics data set. The purpose of recording these additional data is to identify the characteristic drop in PR and rise in NIBP that indicates the onset of AD. This technical note describes the development of a novel, in-house constructed interface that allows PR and NIBP to be recorded alongside the standard urodynamics data set, using a commonly available vital signs monitor and urodynamics workstation.
