Hypotension intra dialytique en cas d’agression rénale aigüe chez les patients Congolais : fréquence, déterminants et issue

Context and objective. Despite progress in hemodialysis (HD), intradialytic hypotension (IDH) remains common. This study aimed to determine the frequency, risk factors and outcome of IDH during acute hemodialysis. Methods. We compiled the records of acute HD sessions in 2 HD centers of Kinshasa between 2008 and 2018. IDH was defined by blood systolic pressure 750 ml [p=0.017; aOR 1.97 (1.12-4.21)], anuria [p=0.021; aOR 2.72 (1.33-6.19)], a session of more than 3 hours [p=0.025; aOR 2.78 (1.48-6.05)], sepsis [p=0.020; aOR 3.89 (1.24-12.18)], lower initial systolic blood pressure [p<0.001; aOR 0.97 (0.96-0.98)] and hydration status [p=0.032; aOR 5.57 (1.16-26.64)]. No deaths have been reported, but we had 3 ICU admissions. Conclusion. In the event of acute dialysis, approximately 1 session in 12 is complicated by IDH with a good prognosis. This depends on factors related to the patient and to the dialysis method itself.
