About this study

Official title: Effects of Dexmedetomidine vs Midazolam on Microcirculation in Septic Shock Patients: a Muscle Microdialysis Study

To investigate changes in the concentration of glucose, lactate, pyruvate and glycerol in the extracellular fluid of the skeletal muscle following Dexmedetomidine administration in patients with septic shock.

Read the detailed description

Prospective randomized double blinded study. Investigators planned to enroll 60 cases diagnosed with septic shock All patients will be sedated with Midazolam and remifentanyl in accordance with a local unit protocol.

After a period of six hours of hemodynamic stability, patients were randomized to receive either continuous infusion of Dexmedetomidine at 0.4 μg/kg per hour and remifentanyl (DEX group) or a continuous infusion of a Midazolam and remifentanyl (MDZ Group).

Conditions
Septic Shock
Being tested
Microdialysis Probe (Muscle microdialysis), remifentanyl
Medical subject headings
Shock, Septic

What participants receive

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

  • Microdialysis Probe (Muscle microdialysis)Device

    Interstitial tissue concentrations of lactate, pyruvate, glucose and glycerol were determined at baseline and then every six hours for the following 72 hours after randomization.

    During the study period, conventional treatment was continued as per usual practice. Fluid challenges were performed, and repeated as necessary, to maintain central venous pressure (CVP) ≥8 and pulmonary arterial occlusion pressure (PAOP) ≥12 mmHg. Norepinephrine was titrated to maintain mean arterial pressure (MAP) ≥65 mmHg. Packed red blood cells were transfused when Hemoglobin (Hb) concentrations decreased below 7 g/dL, or if the patient exhibited clinical signs of inadequate systemic oxygen supply.

  • remifentanylDrug

    Only the dose of remifentanyl (initial infusion of 6 µg/kg/h) can be changed to achieve a Goal of sedation: Richmond agitation-sedation scale 0 to -2.

Study groupRoleWhat they receive
DEX groupExperimentalcontinuous infusion of Dexmedetomidine at 0.4 μg/kg per hour and remifentanyl A microdialysis probe was placed into the femoral quadriceps. An initial set of measurements will be obtained during the sedation with Midazolam and remifentanyl (before randomization). This set of measurements will be considered as baseline. Then samples were collected every 6 hours for 3 days. The changes in the energy-related metabolites lactate, the lactate/pyruvate ratio, glucose and glycerol were analyzed. Concomitantly with dialysate sampling, the effects on global haemodynamics, were assessed. Lactate and L/P clearances were also calculated.

Questions about this trial

What is this clinical trial studying?

A study testing Microdialysis Probe (Muscle microdialysis) and remifentanyl in people with Septic Shock, run by Military Hospital of Tunis at 2 sites in Tunisia.

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 3 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 15 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Tunisia. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Zied Hajjej (0021620358907, hajjej_zied@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

changes in the concentration of glucose(mmol/l) in the extracellular fluid of the skeletal muscle (time frame: Time Frame: At baseline and then every six hours for the following 72 hours after randomization). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 15 Feb 2018.
