About this study

Official title: The Effect of Fluid Loading With Early Norepinephrine Administration on Stroke Volume Index, Cardiac Index, Lactate, and Arterial Elastance in Pediatric Septic Shock

The complexity of pediatric septic shock arise from its varied pathophysiology, which includes systemic inflammation, cardiovascular collapse, and multiple organ dysfunction. Current standard treatments, which primarily focusedon fluid resuscitation, had exhibited several problems. Excessive fluid resuscitation has been associated with complications such as fluid overload, which may cause conditions such as pulmonary edema and organ dysfunction, leading to worsened outcomes. This emphasizes the need for alternative therapeutic strategies that can effectively manage hemodynamic instability while minimizing the risks of fluid overload. In adult patients, the early use of vasopressors has been recommended to restore perfusion in patients with septic shock, compared to repeated fluid loading. However, previous research on the use of norepinephrine and the preload status of the pediatric population is still limited. In addition, the use of fluid resuscitation does not always exhibit the desirable response, which is the increase of blood pressure. This is because the blood pressure depends not only on the stroke volume but also the vascular resistance. Consequently, predicting blood pressure elevation after fluid resuscitation remains challenging. Based on previous research, arterial elastance has the potential to predict the increase of blood pressure in response to fluid administration. Thus, this study aimed to investigate the effects of early administration of fluid resuscitation combined with norepinephrine in pediatric septic shock patients and evaluate the useof arterial elastance as a predictor of blood pressure response following fluid resuscitation. Finally, this study will also evaluate the parameters such as stroke volume index, cardiac index, lactate clearance , arterial elastance in pediatric patients with septic shock who were resuscitated using the hemodynamic support guidelines according to the Surviving Sepsis Campaign protocols.

Research Objectives

  1. Evaluate the changes in preload between the pediatric septic shock patients receiving fluid loading with early administration of norepinephrine compared to those who only receive fluid loading.
  2. Evaluate the changes in stroke volume index, cardiac index, and mean arterial pressure between the pediatric before and after treatment in both groups.
  3. Evaluate the changes in lactate clearance before and after treatment in both groups.
  4. Assess the sensitivity and specificity of arterial elastance as a predictor of blood pressure response in patients receiving fluid resuscitation.

What participants receive

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

What is being measured

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

  1. stroke volume index

    Evaluate the changes in stroke volume index using Ultrasonic Cardiac Output Monitor (USCOM), in units ml/m2, between the pediatric septic shock patients receiving fluid loading with early norepinephrine compared to those who only receive fluid loading

    Measured: evaluate one hour after intervention

  2. cardiac index

    Evaluate the changes in cardiac index Ultrasonic Cardiac Output Monitor (USCOM), in units L/m2/minute,between the pediatric septic shock patients receiving fluid loading with early norepinephrine compared to those who only receive fluid loading

    Measured: evaluate one hour after intervention

  3. Lactate

    Lactate clearance is defined as the change in lactate levels between two time points and is expressed as a 10-20% reduction in lactate per hour or a reduction of at least 10% within 6 hours during initial resuscitation

    Measured: evaluate one hour after intervention

Secondary outcomes (2)
  1. arterial elastance

    Arterial elastance is obtained using the formula: (0.9 x systolic blood pressure)/stroke volume or mean arterial pressure/stroke volume

    Measured: evaluate one hour after intervention

  2. pulmonary edema

    pulmonary edema shown by B-line using lung ultrasound

    Measured: evaluate one hour after intervention

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Norepinephrine and Ringer's Lactate in people with Septic Shock and Sepsis, run by Universitas Indonesia at 1 site in Indonesia.

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 4 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 20 Jun 2024. 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 Indonesia. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

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?

stroke volume index (time frame: evaluate one hour after intervention). The study lists 3 primary outcomes in all. 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 NCT06461390, which also lists 5 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 20 Jun 2024.
