the HD &#40;1 in 14 treatments&#41;&#46; Intradialytic hypertension is a complication that may be prevented by appropriate adjustment of the target weight&#44; of the dialysate sodium content and of high blood pressure medication&#46;<a class="elsevierStyleCrossRefs" href="#bib0295"><span class="elsevierStyleSup">21&#44;22</span></a> However&#44;

In fact&#44; many of the factors that contribute to this intradialytic hypotension are due to actions taken by healthcare professionals who&#44; if they had performed them in a different way&#44; could have avoided it &#40;rapid or excessive ultrafiltration&#59; rapid reduction in plasma osmolality&#59; prescription of an incorrectly low dry weight objective&#59; prescription of antihypertensive drugs pre-dialysis&#59; food intake during the session&#59; composition of the dialysis fluid low in sodium and in calcium&#59;

Therefore&#44; it is advisable to record the times and to determine whether it is common and frequent practice in the unit&#44; which would be regarded as a failure&#44; or if they are only sporadic and totally justified cases&#46;

The person responsible for the dialysis unit should establish a routine on safety as part of the quality assessment and performance improvement process&#46; Several lines of research&#44; including conducting surveys on patients and dialysis professionals&#44;
