Abstract
AIM
The aim of our study was to determine the prevalence and factors associated with intradialytic hypotension in our cohort of chronic hemodialysis patients.
METHODS
This was a prospective monocentric study over a six-month period. Intradialytic hypotension was defined as a decrease in systolic blood pressure ≥ 20mmHg or a decrease in mean arterial pressure of 10mmHg associated with clinical events and the need for nursing interventions. The groups were compared using univariate analysis of variance.
RESULTS
We included 48 patients and counted 3014 hemodialysis sessions. The mean age was 44.7±15 years. The prevalence of intradialytic hypotension was 12.4%, with cramps 20 (41.7%) as the main symptom. Factors associated with frequent intradialytic hypotension compared to the groups without intradialytic hypotension and with infrequent intradialytic hypotension were age (61±13 years, p=0.018), diabetes (33.3%, p=0.019), high body mass index (27, 3±7.8kg/m2, p=0.002), interdialytic weight gain ≥ 5% of baseline weight (66.7%, p=0.033), hourly ultrafiltration (800±275ml/h, p=0.037) and perdialytic feeding (33.3%, p=0.016). Low pre-dialysis diastolic blood pressure (72±13mmHg, p=0.012) and high baseline weight (73.9±17.5kg, p=0.028) were associated with frequent versus infrequent intradialytic hypotension.
CONCLUSION
Intradialytic hypotension is common in our context. Its prevention in at-risk patients is critical to reducing morbidity and mortality and improving quality of life.
