Changes of Hemodynamic Parameters after Intradialytic Glucose Injection.

Area of Science:

• Nephrology
• Cardiovascular Physiology

Background:

• Intradialytic hypotension (IDH) is a common and challenging complication during hemodialysis (HD).
• Existing strategies for preventing IDH are often insufficient, necessitating novel therapeutic approaches.

Purpose of the Study:

• To investigate the efficacy of intravenous glucose infusion in preventing symptomatic IDH during HD.
• To analyze the hemodynamic effects of glucose administration on blood pressure and heart rate in chronic kidney disease (CKD) patients.

Main Methods:

• A prospective study involving 35 CKD patients undergoing HD.
• Administration of a 40% glucose solution (0.5 g/kg dry weight) 30 minutes into HD.
• Continuous monitoring of systolic (SBP), diastolic (DBP), mean arterial pressure (MAP), pulse pressure (PP), and heart rate (HR).
• Assessment of relative volume overload using bioimpedance spectroscopy.

Main Results:

• Glucose infusion led to significant increases in SBP, DBP, MAP, and PP at various time points during HD.
• Observed interactions between hemodynamic parameters and baseline heart rate, as well as fluid overload.
• Crucially, no symptomatic hypotensive episodes were recorded in participants receiving glucose infusions.

Conclusions:

• Intravenous glucose administration during HD is an effective method for preventing symptomatic intradialytic hypotension.
• This intervention does not appear to precipitate severe hypertensive episodes, offering a safe alternative for IDH management.
