About this study

Official title: Use of Isotonic Solutions Versus Hypotonic Solutions for Preventing Hospital Acquired Hyponatremia.

The purpose of this study is to determine if isotonic solutions reduce the risk of hospital acquired hyponatremia compared with hypotonic solutions.

Read the detailed description

Multicenter, Randomized, Controlled clinical trial.

The purpose of this study is to determine if isotonic solutions reduce the risk of hospital acquired hyponatremia compared with hypotonic solutions

This study will include 150 patients in 2 groups according to these type of pathology: group 1: medical conditions which includes respiratory problems (pneumonia, bronchiolitis, acute asthma attack) and acute gastrointestinal problems (bacterial or viral gastroenteritis) and group 2: surgical conditions (pre, peri or postoperative patients will be included). Each group will be randomized to receive 3 types of interventions: 0.3% Saline (hypotonic solution), 0.45% Saline (hypotonic solution) or 0.9% Saline (isotonic solution). In non-dehydrated patients the daily total volume of liquid infused will be determined by the volumetric Holliday- Segar* formula and the daily total volume will be calculated by adding the maintenance requirements (using the Holliday Segar formula) to the fluid deficit (according to percent of estimated weight**) in dehydrated patients.

The glucose concentrations in the first group will be 3.3%, and in group 2 and 3 will be 5%. The potassium concentration will be 20mEq/L in all groups. Blood samples will be collected before, 8 hours and 24 hours after the start of intravenous fluid, for the analysis of sodium, potassium, glucose, urea and creatinine. The adverse clinical outcomes at 8 and 24 hours of the start of intravenous fluid will also be recorded. The sodium plasma level, the incidence of hyponatremia and the adverse clinical outcomes will be compared.

*0-10 kilogram (kg): 100ml/kg per day; 10-20 kg: 1000 ml + 50 ml/kg/day over 10 kg; >20 kg: 1500 ml + 20ml/ kg over 20kg

** In patients under 10 kg correspond to a loss of 5% (50 mL/kg) in mild dehydration and 10% in moderate dehydration. In 10 kg or more: 3% (30 mL/kg) in mild dehydration and 6% (60 mL/kg) in moderate dehydration.

What is being measured

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

  1. Hospital Acquired Hyponatremia

    Serum sodium less than 135 mEq/L at 8 hours in a patient with normal serum sodium (135 mEq/L to 145mEq/L) at the beginning of the study

    Measured: 8 hours

Secondary outcomes (2)
  1. Dysnatraemias at T8

    hyponatraemia (defined as serum sodium < 135 mmol/L), normonatremia (defined as serum sodium 135-145 mmol/L) or hypernatraemia (defined as serum sodium > 145 mmol/L)

    Measured: 8 hours

  2. Adverse Reactions Attributed to Acute Plasma Sodium Changes

    Adjudicated Morbidity Attributed to Acute Plasma Sodium Changes assessed at 8 hours

    Measured: 8 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 0.3% Saline in 3.3% dextrose, 0.45% Saline in 5% dextrose and 0.9% Saline in 5% dextrose in people with Hyponatremia, run by Instituto Tecnologico y de Estudios Superiores de Monterey.

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 7 inclusion and 11 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 16 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

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

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Dec 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Hospital Acquired Hyponatremia (time frame: 8 hours). 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 NCT01909336, which also lists 3 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 16 Dec 2016.
