Title: On-line optical sensing of blood volume changes to prevent intradialytic hypovolemia.
Abstract: Intradialytic hypovolemia is a common complication of hemodialysis treatments. Blood volume changes that occur during dialysis can be followed by on-line optical sensing of the patient's hematocrit. Characteristic curves of blood volume changes can be seen in fluid overloaded patients with symptoms of hypovolemia, i.e. cramps, hypotension. The relative blood volume changes in those who have fluid removed to their ideal "dry" weight without symptoms will be shown in comparison. As Phase I of a CQI project, the nephrologist and dialysis nurses at the London Health Sciences Centre performed a cross-sectional study to define the frequency of these curves and their relationship to intradialytic symptoms. The analysis of these curves can be used to re-assess "dry" weights, prevent intradialytic hypovolemia and decrease the use of antihypertensive agents. The correlation of our findings with the results of an independent hypotensive CQI study will be presented.
