Assessment of microcirculatory function during hemodialysis

Area of Science:

• Nephrology
• Vascular Biology
• Medical Technology

Background:

• Patients with chronic kidney disease (CKD) often have impaired microcirculation and vascular damage.
• Hemodialysis (HD) can exacerbate microcirculatory dysfunction due to repetitive ischemic stress, contributing to high mortality.
• Current HD monitoring focuses on systemic parameters, missing crucial microcirculatory changes.

Purpose of the Study:

• To review the role of microcirculatory monitoring in hemodialysis patients.
• To highlight the potential of intradialytic microcirculatory assessment for early detection of circulatory stress and end-organ ischemia.
• To discuss the clinical relevance and future applications of microcirculation monitoring in optimizing HD treatment.

Main Methods:

• Review of noninvasive technologies used to assess microcirculation in HD patients.
• Analysis of studies evaluating microcirculatory responses during HD treatment.
• Assessment of the utility, practicality, and clinical relevance of different monitoring methodologies.

Main Results:

• Hemodialysis patients consistently demonstrate impaired microcirculation.
• HD treatment imposes additional stress on already compromised vascular beds.
• Existing noninvasive technologies show variable utility and clinical relevance for intradialytic monitoring.

Conclusions:

• Intradialytic microcirculation monitoring offers valuable insights into individual patient responses to HD.
• This monitoring approach has the potential to enable precision medicine for improved HD delivery.
• Adoption into clinical practice could significantly enhance current treatment outcomes for HD patients.
