Introduction:The intra- dialytic hypertension is a complication usually defined by an increase in
mean arterial pressure above 15mmHg during or immediately after the dialysis session .Materials
and methods:Retrospective study of 28 months ( May 2010 to September 2012) in our hemodialysis
center aimed to determine the prevalence and risk factors for intra- dialytic hypertension.Results:
The intra- dialytic hypertension was noted in 7.9 % of sessions . The above 60years age, diabetes ,
heart disease , male sex , the temperature of the dialysate , and the shooting ratio of weight / dry
weight , were identified as contributing factors its occurrence . Sodic profiles significantly influence
the prevalence of this complication. His support was based primarily on the optimization of
ultrafiltration in 75 % of cases. Conclusion : The intra- dialytic hypertension is a rare complication
, its pathophysiology is poorly understood and its treatment is not codified mainly based on
optimizing the basis weight that should be done with caution . Further studies are needed to assess
the epidemiology, pathophysiology and management of this complication
