What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study looked at 40 ICU patients to see if a heart ultrasound before dialysis could predict dangerous drops in blood pressure. Doctors measured heart function using several ultrasound markers. The goal is to help plan safer dialysis for critically ill patients.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of adult patients (≥18 years) admitted to the intensive care unit (ICU) of a tertiary care hospital who are clinically indicated for continuous veno-venous hemodiafiltration (CVVHDF) due to acute kidney injury or fluid overload. All participants must have adequate transthoracic echocardiographic imaging quality prior to dialysis initiation. Only patients whose legal representatives provide informed consent will be included. Both male and female patients will be enrolled, regardless of underlying comorbidities, provided they meet the inclusion and exclusion criteria.

Ages

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥18 years * Admission to the intensive care unit (ICU) * Clinical indication for initiation of continuous veno-venous hemodiafiltration (CVVHDF) * Ability to obtain adequate transthoracic echocardiographic (TTE) images prior to CVVHDF * Written informed consent obtained from the patient's legal representative Exclusion Criteria: * Acute coronary syndrome, severe valvular disease, or pericardial effusion affecting cardiac function * Cardiac arrhythmias such as atrial fibrillation or ventricular tachycardia that interfere with accurate Doppler measurements * Presence of cardiac devices such as pacemakers, LVADs, or implantable cardioverter defibrillators (ICDs) * Poor echocardiographic window due to severe lung disease or chest wall abnormalities * Estimated life expectancy \<24 hours or do-not-resuscitate (DNR) orders in place * Inability to obtain informed consent due to lack of legal representative * Transfer to another facility before CVVHDF initiation or change in renal replacement strategy (e.g., switch to peritoneal dialysis) * Incomplete echocardiographic measurement due to technical limitations
