Intradialytic Hypotension Pathophysiology and Therapy Update: Review and Update

Background
Intradialytic hypotension (IDH) is the most prevalent complication during hemodialysis (HD) sessions, affecting 10% to 12% of patients. It is linked with temporary ischemic stress in vital organs, increasing patient mortality. Various definitions of IDH have been proposed, and a strong correlation has been found between patient outcomes and the absolute lowest systolic blood pressure. The most probable underlying pathophysiology of IDH involves a reduced effective blood volume and decreased plasma tonicity. Optimizing the dialysis prescription and interventions during and after the dialysis session is sometimes effective for reducing IDH risk.
Aim and Method
This review discusses the pathophysiology, prevention, and therapy of IDH updates. To achieve this aim, Scopus, EMBASE, PubMed, Google, and Google Scholar were searched for articles published in the last two decades using phrases and keywords.
Conclusion
Intradialytic pathophysiology is ambiguous and unclear. The evidence for the effectiveness of the known therapies and maneuvers is limited. Ideally, IDH prevention should be the target; however, IDH management is sometimes needed. Different obstacles require further clinical research.
Intradialytic hypotension (low blood pressure) (IDH) occurs during hemodialysis (HD) sessions or just after the HD session finishes, which affects 10% to 12% of patients. It is linked to brief vascular stress in important organs, raising death risk. There are different ideas about what IDH means, and there is a strong link between how well a patient does and having the lowest high blood pressure. A lower effective blood volume and lower plasma tonicity are most likely to be at the root of intellectual disability. IDH risk can sometimes be lowered by ensuring that the dialysis prescription and treatments during and after the session are as good as possible. This review aims to study the etiology, prevention, and treatment of IDH updates.
The cause of IDH is unclear, and there is little proof that the known treatments and interventions work. The goal should be to prevent IDH from happening, but sometimes, it's necessary to handle it. More clinical studies are needed to solve several problems.
