Trial summary

Currently, decisions regarding volume management for dialysis sessions in the ICU are made in large part on the nephrologists'/intensivists' overall gestalt. This gestalt is based upon a combination of commonly used measures of circulatory function, the physical exam, fluid balance, estimates of dialysis dry weight… Read more about this study

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Any patient 18 years and older who is admitted to the OHSU Hospitals ICUs with ARF, or End Stage Renal Disease (ESRD) for a diagnosis other than hyperkalemia, as the sole determinant for that level of care, will be invited to participate. The patient must have acute or chronic needs for dialytic support during their ICU stay in order to qualify for the study. Dialysis support may be provided by intermittent HD sessions, or continuous venovenous hemodiafiltration (CVVHDF) depending on the underlying hemodynamic stability of the patient.

Who may be able to join

  • Admitted to OHSU Hospitals ICUs
  • Patient has acute or chronic needs for intermittent hemodialysis support during their ICU stay for any reason other than isolated hyperkalemia
  • Central venous access in place separate from the dialysis catheter, or arteriovenous fistula or graft
  • Two or more organ systems affected by critical illness requiring supportive care as documented in the medical chart.

Who cannot join

  • age younger than 18 years old
  • Weight > 160 kg
  • burns greater than 40% total body surface area
  • known cardiac or vascular aneurysm
  • contraindications to femoral arterial puncture
  • diagnosis of peripheral vascular disease

About this study

Currently, decisions regarding volume management for dialysis sessions in the ICU are made in large part on the nephrologists'/intensivists' overall gestalt. This gestalt is based upon a combination of commonly used measures of circulatory function, the physical exam, fluid balance, estimates of dialysis dry weight, and monitoring changes in relative blood volume status using devices such as the Crit-Line™ III, and central venous pressures. However, these tools perform poorly in predicting the circulatory system's overall response to dialysis. Consequently, episodes of dangerously low blood pressure are still frequently encountered. Better techniques to predict the circulatory system's response to dialysis are much needed. The intent of this study is to test newer metrics of circulatory system function for their ability to predict low blood pressure episodes during dialysis. This is important because it may enable the design of newer treatment strategies created to prevent low blood pressure episodes during dialysis and improve patient outcomes. The investigators overall hypothesis is that newer measures of vascular volume and dynamic indices of fluid responsiveness, previously found to better reflect cardiac preload state than currently used parameters, will better predict low blood pressure episodes during dialysis than current methods.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transpulmonary ThermodilutionProcedure or surgery

    Also called Pulsion Medical Systems, PiCCO2, PiCCO

    A PiCCO femoral catheter will be placed and PiCCO parameters will be obtained using transpulmonary thermodilution after continuous dialysis is ordered or just prior to initiation of intermittent dialysis, hourly until either completion of intermittent dialysis or 8 hours of continuous dialysis is completed.

What is being measured

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

  1. hypotensive episode

    A mean arterial pressure of <60 mmHg, a 15% decrease from baseline systolic blood pressure at the start of the dialysis treatment regardless of modality, the need for fluid bolusing >7 mL/kg body weight, or initiation or increase of vasopressor medication in order to maintain MAP >60 mmHg.

    Measured: during or within one hour post dialysis

Secondary outcomes (6)
  1. fluid removal tolerance

    Parameters measured will be examined to discriminate between patients that will tolerate fluid removal (UF) during the following 4 hours of dialysis if UF is ordered by physician (no hypotensive events with > 500 mL fluid removal) from those that won't

    Measured: during the 4 hours following parameter measurement in dialysis

  2. predicted volume of fluid that can be removed without hypotensive events

    Parameters measured will be examined to see if they can predict the volume of fluid successfully removed without hypotensive events

    Measured: during dialysis

  3. mortality in the ICU

    Measured: duration of ICU stay

  4. All cause mortality

    Measured: 30 days

  5. Length of stay in ICU

    Measured: ICU stay duration

  6. Length of stay in hospital

    Measured: duration of hospital stay

The study was withdrawn before enrolling participants, so there are no results.

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?

hypotensive episode (time frame: during or within one hour post dialysis). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01171352, which also lists 16 linked publications.

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 5 Jun 2019.
