About this study

Official title: Comparison of Plasma Concentrations of Lidocaine and Bupivacaine After Ultrasound-guided Axillary Approach to Brachial Plexus Block Used With Different Dilute Mixture Solutions for Upper Limb Trauma Surgery

The doses of local anesthetics can be decreased with the use of ultrasound guidance. In case of using mixture solutions the benefits and drawbacks are controversial. The plasma concentrations were not studied up to this time in this kind of settings, so investigators believe that this is the first work that shows how lidocaine change the plasma concentration of bupivacaine after axillary approach to brachial plexus employed with different dilute and mixed solutions for upper limb surgery in trauma patients.

Read the detailed description

Total of 30 American Society of Anesthesiologist (ASA) I-III adult patients scheduled to elective or emergency trauma surgery of hand and forearm under ultrasound-guided (UG) brachial plexus block (BPB) are planned to be assigned into this randomized-prospective observational study after approval by the University Research Ethics Board, Pécs University Medical School, Hungary. All of the patients will receive detailed information about the planned BPB techniques and surgeries, then written informed consents will be obtained.

Study participants are planned to be assigned randomly by the research coordinator into 3 groups (Lidocaine, Bupivacaine and mixture solution) according to the concentration of lidocaine and bupivacaine in the mixture solution.

Standardized UG Axillary-supraclavicular (AX-SC) approach to the BP is planned to be performed under sterile conditions by the same anesthesiologist. The standardized dose is 0.4 ml/kg with the targeted maximized the single-shot volume of 30 ml.

Blood samples will be taken at 0-time point (straight after the administration of BP injection) and 30, 60, 240 and 480 minutes after. Plasma concentrations are determined, the results are collected and analyzed.

Under standard monitorization, vital parameters, data are collected on the onset time and duration of actions of local anesthetics (LAs).

Questions about this trial

What is this clinical trial studying?

A study testing Lidocaine brachial plexus block, Bupivacaine brachial plexus block and Mixture brachial plexus block in people with Arm Injury, run by University of Pecs at 1 site in Hungary.

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 1 inclusion and 1 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 22 Jul 2021. 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 Hungary. 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?

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?

Maximal plasma concentrations (time frame: 0-8 hours). 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 22 Jul 2021.
