About this study

Official title: Impact on Sensitivity and Motor Block Duration of an Intravenous Dexamethasone Injected 90 Min After Making an Axillary Block With Mepivacaine. A Prospective, Randomized, Placebo-controlled Study

Intravenous dexamethasone is used to increase the duration of analgesia of interscalene bloc for shoulder surgery: it extends from 11h to 23h the sensitivity block in shoulder area. However, the time of dexamethasone intravenous injection has not been studied. In all studies, dexamethasone was injected right after the achievement of loco regional anesthesia.

The main objective is to demonstrate that intravenous injection of dexamethasone delayed at 90 minutes in patients who received an axillary block with mepivacaine prolongs the duration of the motor block by 40 minutes.

Read the detailed description

In orthopedic surgery, most of procedures are made under loco regional anesthesia. For a surgery of hand, wrist or forearm, an axillary block is made to obtain an insensitivity (sensitivity block) and an unability to move from elbow to fingers (motor block). Depending on the duration of surgery, less or more than 2 hours, a choice of anesthetic has to be made. For short surgeries, mepivacaine is taken on, but for longer ones, local anesthetics like ropivacaine or levo bupivacaine are recommended. Nevertheless, once surgery started, there isn't any possibility to extend the anesthesia duration in case of an unexpected increase of surgery length. A general anesthesia will therefore be required.

Intravenous dexamethasone is used to increase the duration of analgesia of interscalene bloc for shoulder surgery: it extends from 11h to 23h the sensitivity block in shoulder area(1). However, the time of dexamethasone intravenous injection has not been studied. In all studies, dexamethasone was injected right after the achievement of loco regional anesthesia.

The investigator hypothesized that intravenous dexamethasone could extend anesthetic duration of a mepivacaine axillary block (motor and sensitivity block length) even though dexamethasone was injected 90 min after the achievement of block and could be a good option in case of an unexpected extended surgery.

52 patients will be randomly assigned to two groups:

  • DEXA: dexamethasone 8 mg/2cc I.V. 90 minutes after axillary block
  • Control: Normal saline 2cc I.V., 90 minutes after axillary block These patients will be recruited during the anesthesia interview from 1 hospital, with 5 surgeons performing the surgeries and 15 anesthetists performing the axillary block
  1. After written consent, all patients will have their surgery under regional anesthesia only provided by the axillary block, with mepivacaine 1.5% 25cc.
  2. Time of complete motor and sensitivity block will be monitored and recorded
  3. 80 minutes after achievement of axillary block, if the surgery is not ended, patients will be randomly assigned to one of the two groups : DEXA or Control
  4. Injection will be done 90minutes after achievement of axillary block
  5. Monitoring of motor block and sensitivity block recovery will be done :
  • during the surgery by nurse and surgeon
  • after the surgery in recovering room by nurses each 15min.
  1. Patients will be called on post operative day one for pain evaluation and detection of adverse effects.

What participants receive

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

  • DexamethasoneDrug

    80 minutes after achievement of axillary block, if the surgery is not ended, patients will be randomly assigned to one of the two groups : DEXA or Control. Injection will be done 90minutes after achievement of axillary block.

  • Normal salineDrug

    80 minutes after achievement of axillary block, if the surgery is not ended, patients will be randomly assigned to one of the two groups : DEXA or Control. Injection will be done 90minutes after achievement of axillary block.

What is being measured

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

  1. Duration of motor block

    The evaluation of the appearance of the motor block is done by a neurological examination of the anesthetized hand and forearm every 5 minutes after injection of the local anesthetic during 20 minutes During the intervention, the reappearance of a movement of the hand or forearm is signaled by the surgeon at the request of the anesthetist and corresponds to the end of the motor block.

    After the intervention, a neurological examination is performed every 15 minutes in a recovery room until the appearance of the first movement of the hand

    Measured: within 3 hours after intervention.

Secondary outcomes (4)
  1. Duration of sensitivity block defined as the time between the performance of sensitivity block and appearance of paresthesic or the first analgesia request.

    Measured: within 3 hours (for outcome measure 1) (end of intervention for 2 and 3) and at 24 hours after the intervention

  2. Sedation or general anesthesia request

    Measured: within 3 hours (for outcome measure 1) (end of intervention for 2 and 3) and at 24 hours after the intervention

  3. Pain scores in recovering room

    Measured: within 3 hours (for outcome measure 1) (end of intervention for 2 and 3) and at 24 hours after the intervention

  4. Adverse effects in next 24 hours

    Measured: within 3 hours (for outcome measure 1) (end of intervention for 2 and 3) and at 24 hours after the intervention

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dexamethasone and Normal saline in people with Hand Wound and Wrist Wound, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 5 inclusion and 22 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 19 Jun 2019. 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 France. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Duration of motor block (time frame: within 3 hours after intervention.). 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 19 Jun 2019.
