About this study
Official title: Effect of Dynamic Arterial Elastance and Assisted Fluid Management Software Guided Adjustment of Vasopressor and Fluid Therapy in Septic Shock Resuscitation; A Pilot Study
To investigate the benefit of using the AFM and Eadyn-guided fluid and vasopressor therapy in septic shock resuscitation for mechanically ventilated patients compared with the standard of care. The investigators hypothesize that using the AFM and Eadyn-guided fluid/vasopressor titration in septic shock patients who underwent mechanical ventilation might reduce the time to shock reversal.
Read the detailed description
Hypotension in the context of an intensive care unit has been associated with a higher risk of death and multiorgan dysfunction. Vascular leakage and systemic vasodilatation are brought on by systemic inflammation from infections. These are the hallmarks of septic shock in which 90% of cases of shock are mostly distributive and hypovolemic. Early vasopressors and fluid therapy are increasingly used at the start of vasodilatory shock resuscitation since this method improves the rate of shock control within 6 hours in septic shock resuscitation. Norepinephrine is the first-line vasopressor for vasodilatory shock. However, resuscitation with an accurate amount of fluid and vasopressor is challenging in clinical practice. Fluid overload and overuse of vasopressors are prevalent and increase mortality. Together with a higher dose of norepinephrine, it may increase the risk of ischemic complications.
A new hemodynamic monitoring device (Hemosphere(R) - Edward Lifescience, California, USA) provides two novel parameters for hemodynamic monitoring: the new device with artificial intelligence developed by a retrospective cohort (used for training) and a prospective (local hospital cohort used for external validation). The feature of Hemosphere(R), including dynamic arterial elastance (Eadyn) and stroke volume change prediction (∆SVpredict) as the assist fluid management (AFM) based on arterial pressure waveform analysis by the monitoring software, was detected in arterial line waveform without any complication of a safety issue.
The ratio of pulse pressure to stroke volume (PP/SV) is defined by dynamic arterial elastance (Eadyn), the reciprocal of compliance within the range of 0.8 to 1.0 is the optimization of arterial load that can predict arterial pressure response to fluid administration and vasopressor weaning. The prediction of the stroke volume changes following the upcoming fluid therapy (∆SVpredict) uses stroke volume variation parameters and closed-loop feedback data, which should be less than 10% to indicate optimal fluid administration. Consequently, this technique offers a useful means of evaluating arterial tone related to preload responsiveness parameters predicting the hemodynamic response to increases in cardiac preload.
However, several studies show the benefit of this tool in perioperative patients, and the evidence on the benefit of using this monitoring to guide septic shock resuscitation is limited. In a previous study, Eadyn can predict a decrease in mean arterial pressure linked to a reduction in norepinephrine dosage. This study aimed to investigate the benefit of using AFM and Eadyn-guided fluid and vasopressor therapy in septic shock resuscitation compared with the standard of care

The AFM and Eadyn - guided resuscitation groupDevice
Also called hemosphere, dynamic arterial elastance
A fluid challenge using a stroke volume change prediction (∆SVpredict) and Eadyn guide. If the ∆SVpredict is more than 10%, isotonic crystalloid of 500 ml will be administered in 30 minutes, and the machine's response will be awaited. If ∆SVpredict is still more than 10%, continuous fluid loading was reapplied until SVV was less than 10% (fluid therapy will be stopped if ∆SVpredict is less than 10%) and dynamic arterial elastance (EAdyn) reaches the goal of 0.8-1.0 along with a vasopressor will be administered and titrated every 10 minutes until the target MAP > 65 mmHg is reached. After MAP of 65 achieved, tissue perfusion including urine output, capillary refill time, and serum lactate will be assessed
The standard care for septic shockOther
The standard of care group will be treated according to according to septic shock guidelines 2021; In brief A vasopressor with optimal ideal fluid (at least 30 ml/kg) will be given to achieve the hemodynamic target (MAP ≥ 65 mm Hg) by fluid challenge technique guided by MAP and central venous pressure (CVP) changes after fluid challenge. Fluid-responsive tests can be used as a subsidiary, depending on the attending physician. Early Norepinephrine (NE) infusion can be used with a standard dose of 0.05 mcg/k/min and titrated at the rate of 0.01-0.02 mcg/kg/min every 10 min until 0.25 mcg/kg/min was achieved; then, the second line vasopressor will be added and adjusted to the target of vasopressor. Hydrocortisone can be given according to septic shock guidelines.
After MAP of 65 achieved, tissue perfusion including urine output, capillary refill time, and serum lactate will be assessed

| The standard care for septic shockThe standard of care group will be treated according to according to septic shock guidelines 2021; In brief A vasopressor with optimal ideal fluid (at least 30 ml/kg) will be given to achieve the hemodynamic target (MAP ≥ 65 mm Hg) by fluid challenge technique guided by MAP and central venous pressure (CVP) changes after fluid challenge. Fluid-responsive tests can be used as a subsidiary, depending on the attending physician. Early Norepinephrine (NE) infusion can be used with a standard dose of 0.05 mcg/k/min and titrated at the rate of 0.01-0.02 mcg/kg/min every 10 min until 0.25 mcg/kg/min was achieved; then, the second line vasopressor will be added and adjusted to the target of vasopressor. Hydrocortisone can be given according to septic shock guidelines. After MAP of 65 achieved, tissue perfusion including urine output, capillary refill time, and serum lactate will be assessed | Other | AFM and Eadyn - guided resuscitation group, the standard of care group |

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.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
Contact Ranistha Ratanarat, MD (+66 2419 7767, ranittha@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
time to shock reversal (time frame: 28 days). 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 NCT06937918, which also lists 15 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 27 Apr 2025.
