Effect of Dexmedetomidine vs Esmolol or Placebo on Cerebral Hemodynamics in Septic Shock
A study testing Dexmedetomidine Hydrochloride and Esmolol Hydrochloride in people with Septic Shock and Stress Response, run by Xinchen Wang at 1 site in China.
Trial summary
Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Some researchers proposed that the dysregulated response or organ dysfunction can be lessened by reducing the stress response, which further reduce complication and mortality rates of sepsis.

About this study
Official title: Effect of Dexmedetomidine vs Esmolol or Placebo on Cerebral Hemodynamics in Septic Shock: A Randomized Clinical Trial.
Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Some researchers proposed that the dysregulated response or organ dysfunction can be lessened by reducing the stress response, which further reduce complication and mortality rates of sepsis. Dexmedetomidine is alpha adrenergic receptor agonist, presenting sympatholytic action in certain parts of the brain with anxiolytic, sedative, and pain killing effects. In the experiments of sepsis animal model, dexmedetomidine have been proved to improve serum lactate clearance and the microcirculation. Dexmedetomidine may inhibit inflammation, as it enhances the activity of the immune system while reducing its systemic reaction and lowering cytokine concentrations. There are also evidences in clinical trials with definite safety that dexmedetomidine reduced inflammation, reduced vasopressor requirements and improved organ function. The beta antagonist esmolol has been proposed as a therapy to lower heart rate, thereby improving diastolic filling time, and improving cardiac output, resulting in a reduction in vasopressor support. A recent meta-analysis of 8 randomized studies using esmolol suggested that the 32% risk ratio decreased 28-day mortality, and a meta-analysis of 7 studies using esmolol in patients with sepsis and septic shock was associated with 32% lower 28-day mortality. However, the effect of anti-stress drugs on cerebral hemodynamics is unknown. In this study, investigators are going to apply the technique of transcranial Doppler to assess the reaction of cerebral blood flow in anti-stress group and control group.
Read the detailed description
It is a single-blinded, single-center, randomized trial. Patients with septic shock established within 24 hours in the ICU of Tibet Autonomous Region People's Hospital will be screened for recruitment. After adequate fluid resuscitation, continuous infusion of norepinephrine is given to the patients to maintain a mean arterial pressure (MAP) of 65-75 millimeter of mercury (mmHg). Midazolam and fentanyl are given to achieve the goal sedation of bispectral index (BIS) 40-60, patients who are still with tachycardia (heart rate over 100 b.p.m.) will be recruited. After recruitment, patients in accordance with the random number table are divided into dexmedetomidine group, esmolol group and control group (T0). Patients in the two experimental groups are required to achieve the heart rate goal of 75-95 b.p.m. in one hour by adjusting the dose of dexmedetomidine or esmolol every twenty minutes. All patients acquired the hemodynamic evaluation at T1, T2, T3, T4 (6, 12, 18, 24hours after enrollment). The hemodynamic evaluation including transcranial Doppler of middle cerebral artery(MCA), deep middle cerebral vein (DMCV), basal vein Rosenthal (BVR) and transverse sinus (TS), hemodynamic parameters acquired by the pressure-recording analytical method through peripheral arterial with Mostcare. Demographic characteristics, diagnosis, laboratory reports and drug dose are collected during the study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dexmedetomidine HydrochlorideDrug
The continuous intravenous infusion of dexmedetomidine (0.1mg/ml) will start at 0.1ug/kg/h, increasing every 20 minutes by a step change of 0.05-0.2ug/kg/h to reach the target heart rate with the expectation that this should be within 12 hours. The infusion will be reduced by step change, and if necessary, ultimately stopped if the heart rate fall below 80b.p.m..
Esmolol HydrochlorideDrug
The continuous intravenous infusion of esmolol (10mg/ml) will start at 20mg/h, increasing every 20 minutes by a step change of 20mg/h to reach the target heart rate with the expectation that this should be within 12 hours. The infusion will be reduced by step change, and if necessary, ultimately stop if the heart rate fall below 80b.p.m..

What is being measured
The primary outcome is the main question the study is designed to answer.
The cerebral hemodynamic change caused by the anti-stress therapy
The cerebral hemodynamics will be evaluated according to the features of the blood flow of MCA, DMCV, BVR and TS measured by transcranial doppler, as well as regional cerebral oxygen saturation measured by the near infrared spectroscopy at Hour 0, Hour 6, Hour 12, Hour 18 and Hour 24. The difference will be acquired by contrasting between two intervention group and one control group.
Measured: Hour 0, Hour 6, Hour 12, Hour 18 and Hour 24.
Secondary outcomes (1)
The systemic hemodynamic change caused by anti-stress therapy
The systemic hemodynamic changes will be acquired through the pressure-recording analytical method with Mostcare, blood pressure and electro cardiac monitor, central venous pressure (CVP) monitor, trans thoracic echocardiography, and blood gas at Hour 0, Hour 6, Hour 12, Hour 18 and Hour 24. The difference will be acquired by contrasting between two intervention group and one control group
Measured: Hour 0, Hour 6, Hour 12, Hour 18 and Hour 24

Questions about this trial
What is this clinical trial studying?
A study testing Dexmedetomidine Hydrochloride and Esmolol Hydrochloride in people with Septic Shock and Stress Response, run by Xinchen Wang at 1 site in China.
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 4 inclusion and 6 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 13 Dec 2023. 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 China. 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.
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?
The cerebral hemodynamic change caused by the anti-stress therapy (time frame: Hour 0, Hour 6, Hour 12, Hour 18 and Hour 24.). 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 NCT06169475, which also lists 7 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 13 Dec 2023.
