Overview

QTc prolongation and premature ventricular contractions (PVCs) are common in hemodialysis (HD) patients and are associated with sudden cardiac death.

It is known that higher dialysate bicarbonate is associated with more QTc prolongation during HD sessions.

This study aims to assess the effects of lower (30 mEq/L) versus higher (35 mEq/L) dialysate bicarbonate in adult maintenance HD patients admitted to the hospital.

The investigators will randomly assign subjects to lower versus higher dialysate bicarbonate concentrations during their hospital stay for up to a maximum of six HD sessions or until their hospital discharge.

Eligibility

Inclusion Criteria:

  • prevalent end-stage renal disease, on maintenance HD > 90 days
  • age ≥ 18 years old
  • thrice weekly HD

Exclusion Criteria:

  • hemoglobin < 8.0 g/dL
  • pregnancy
  • any physical, mental or medical condition which limited the ability to provide written informed consent

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
