Trial summary

Brachial plexus blocks have some advantages, but also have some disadvantages as well. As with all nerve blocks, having to wait sometime for an effective block, sometimes failure to achieve an adequate block and possible requirement for isolated nerve block, having to wait a long time for resolution of the block, and… Read more about this study

About this study

Brachial plexus blocks have some advantages, but also have some disadvantages as well. As with all nerve blocks, having to wait sometime for an effective block, sometimes failure to achieve an adequate block and possible requirement for isolated nerve block, having to wait a long time for resolution of the block, and immobilization of the extremity for some time can be seen as handicaps for brachial plexus block as well. In the present study, Study was aimed to compare the effects of bupivacaine warmed to body temperature and kept at room temperature on the onset time of ultrasound guided infraclavicular brachial plexus block.

Read the detailed description

The study design was approved by the locale ethics committee. This double-blinded, randomized, controlled clinical trial recruited 60 patients aged between 18 and 65 years with the American society of anesthesiologists (ASA) physical status classification systems I/II and III who were candidated for surgical operations on any of the forearm, wrist and hand regions. All the participants were asked to sign an informed consent form after having been provided with details of the aim and proceedings of the study.

Patients were excluded from the study if they had a neurological and neuromuscular disorders, psychiatric problems, cardiopulmonary diseases, coagulopathy, infections or allergy to local anesthetic agents.

The patients were equally and randomly distributed into a 24C° 20 ml 0,5% bupivacaine group (Group 1), and 37C° 20 ml 0,5% bupivacaine group (Group 2) via closed envelope technique. All the participants were premedicated with 0.05 mg/kg of intravenous midazolam and monitored routinely before attempting nerve block.

Bupivacaine stored for at least 2 hours in a bain-marie (Memmert Waterbath WNB7, Germany) at 38˚C (regular temperature calibration was made) for Group 2.

The block process was accomplished by an anesthesiologist, who was blind to the temperature of bupivacaine and local anesthetic agent was administered by different anesthesiologist.

At the end of the ICBP block, an anesthetist blinded to the technique evaluated sensory and motor block in every minutes between 5th and 30th minutes as follows. The innervated areas (each dermatome) was evaluated using a pinprick test. The motor block was evaluated by bromage modified scale in every minutes between 10th and 30th minutes. Anxious patients were administered additional midazolam. Subjects refusing awake surgery were administered a propofol infusion with supplemental oxygen as necessary.

What is being measured

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

  1. Evaluate sensory block's onset time

    Pain was evaluated by pinprick test (yes-there is a pain/ no-there is no pain)

    Measured: 30 minutes after Brachial Plexus Block

Secondary outcomes (1)
  1. Evaluate motor block's onset times

    Motion on distal arm was evaluated by bromage scale (0- full flexion of distal arm, 3-unable to move distal arm)

    Measured: 30 minutes after Brachial Plexus Block

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Bupivacaine Hydrochloride 5 MG/ML in people with Effect Increased, run by Erzurum Palandöken State Hospital at 1 site in Turkey (Türkiye).

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 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 20 Nov 2017. 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 Turkey (Türkiye). 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 phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Evaluate sensory block's onset time (time frame: 30 minutes after Brachial Plexus Block). 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 20 Nov 2017.
