About this study

Official title: The Effect of Head Out Water Immersion During Dialysis on Clinical Parameters, Hemodynamic Parameters, and Hormonal Parameters in 10 Hemodialysis Patients

Immersion to the neck before and during hemodialysis session may increase intravascular volume, potentiate the ability to ultrafiltrate excess water, with less symptoms of shock, muscle crumps etc.

The aim of the present study is to compare blood volume, hemodynamic and endocrine parameters of chronic ESRD patients undergoing forth dialysis session in water immersion vs. control regular session.

Read the detailed description

10 chronic hemodialysis patients, treated in the hemodialysis unit of Asaf-Harofeh Medical Center will be enrolled in the study.

Hemoglobin and albumin will be detected at baseline, and a recent (less than one year) echo will be used for the detection of ejection fraction.

The study will be a cross over study. Each set of studies will consist of two dialysis sessions, an immersion session, and a dry, non-immersion session. The study sessions will be short, 3 hours sessions with 250-350 ml/min blood flow (depends on the patients access) dialysate flow was 500 ml/min and dialysate sodium was 137meq/l. The temperature of the dialysate will be adjusted to 37°C and its composition as follows: Na+ = 137 mEq/L, K+ = 2.0 mEq/L, Ca2+ = 3.0 mEq/L, Mg2+ = 1.0 mEq/L, HCO3-= 30 mEq/L, glucose =100 mg/dL, CH3COO-= 8 mEq/L. The sodium concentration will be constant during treatment.

Ultrafiltration will be determined as the mean of UF during the ten previous sessions±10% according to the patients weight on admission. The immersed and dry session will be done in the midweek sessions, in random order, at least one week apart from each other.

Head-Out Water Immersion

A bath will be used for immersion. The bath will be filled with purified water before each of the session, and will be heated to 34-35°C. Patients will enter the bath and sat upright for few minutes and then connected to dialysis. The water will circulate through a thermostats and heating device in order to maintain a constant temperature.

Patients with arterio-venous fistula or graft in their arm will be immersed in water up to their axilla, with their arm lining on a floating pad. For patients with perm-cath immersion will only be done up to 5 cm below the catheter insertion.

Study procedure

Subjects will enter the bath and sit for few minutes, after which blood samples will be drown for baseline measurement. During the session blood pressure and heart rate will be measured every 15 minutes by conventional sphygmomanometry. and blood volume will be estimated by using blood volume monitor (Crit-Line).

Blood samples will be drown at baseline and after one hour, and before caseation of the session for plasma renin activity, aldosterone, atrial natriuretic peptide. Baseline and end of session urea will also measured for URR.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. symptomatic hypotension during dialysis

    a decrease of systolic BP of 22mmHG or more or decrease of diastolic BP of 10 mmHg or more accompanied with symptoms of muscle crumps, presyncope or syncope

    Measured: 3 hours

Secondary outcomes (2)
  1. blood pressure changes compared to baseline

    analysis by electronic sphygmomanometer every 15 minutes during the session

    Measured: 3 hours every 15 min

  2. Atrial natriuretic peptide change compared to baseline

    blood will be drown from arterial line at baseline, after one hour and after 3 hours before dialysis termination.

    Measured: 0, 1, 3 hours

Questions about this trial

What is this clinical trial studying?

A study testing immersion in people with Intradialytic Hypotension and Immersion, run by Assaf-Harofeh Medical Center at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

symptomatic hypotension during dialysis (time frame: 3 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2017.
