About this study

Official title: Atracurium Mixed With Magnesium Sulfate Versus Atracurium Alone as Adjuvant to Lidocaine in Intravenous Regional Anesthesia

The present clinical study will be undertaken to compare study between the effect of atracurium with lidocaine versus addition of magnesium sulphate to the same doses with lidocaine administrated alone in IntraVenous Regional Anaesthesia to access motor block, sensory block, tourniquet pain and post operative analgesia .Also assessment of patient and surgeon satisfaction .

Read the detailed description

patients will be divided randomly into three groups (A, B, C) of 25 each, according to computer generated table of random numbers.

  • Patients in group A will receive 3 mg/kg of lidocaine 2% diluted with saline to a total volume of 40 ml.
  • Patients in group B receive 3 mg/kg of lidocaine 2% + 2 mg atracurium diluted with saline to a total volume of 40 ml.
  • Patients in group C will receive 3 mg/kg of lidocaine 2% + 2 mg atracurium mixed with 10 mg /kg magnesium sulphate diluted with saline to a total volume of 40 ml.

Onset of sensory block will be assessed by a pin prick performed at 1 minute interval in the dermatomal sensory distribution of the medial and lateral ante brachial cutaneous, ulnar, median and radial nerves. Sensory block onset time will be recorded as time elapsed from injection of drug to sensory block achieved in all dermatomes.Onset of motor block will be assessed by asking the subject to flex and extend his/her wrist and fingers. Monitoring of motor block will be assessed by Modified Bromage Score . Complete motor block will be recorded when no voluntary movement will be possible.

At the end of surgery, the tourniquet will be deflated by a cyclic deflation technique and recording this :

  • Sensory block recovery time
  • Motor block recovery time
  • Mean arterial pressure (MAP),
  • heart rate (HR)
  • visual analogue scale (VAS) will be recorded at 0, 15 min , 1, 6, 12, and 24 h.
  • The time to first analgesic requirement will be recorded (the time elapsed from tourniquet release until first patient request for analgesic).

What participants receive

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

  • LidocaineDrug

    Two intravenous cannulae will be placed; one in a vein on the dorsum of the hand to be operated (22 gauge) and the other in the opposite hand. A double tourniquet will be positioned on the upper arm of the hand to be operated. Arm will be elevated for 2 min.

    Circulatory isolation of arm will be confirmed by inspection of the color of the limb, absence of radial pulse and loss of pulse oximetry tracing in the ipsilateral index finger. The upper (proximal) tourniquet will then be inflated to a pressure of 100 mmHg above the systolic blood pressure of the patient. The anesthetic solution will be prepared by an observer and will be given over a period of 90 seconds.

    Two intravenous cannulae will be placed; one in a vein on the dorsum of the hand to be operated (22 gauge) and the other in the opposite hand. A double tourniquet will be positioned on the upper arm of the hand to be operated. Arm will be elevated for 2 min.

What is being measured

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

  1. postoperative analgesia

    postoperative analgesia measured by VAS of 0-10 (0= no pain and 10=Worst pain imaginable ) during the first 24 hours

    Measured: 24 hour

Secondary outcomes (1)
  1. The onset and recovary times of sensory and motor block , first analgesic request , tourniquet pain ,side effects of study drugs , and quality of anesthesia assessed by patients and surgeons

    Onset of sensory block assessed by pinbrick of the arm . Onset of motor block will be assessed by asking the subject to flex and extend his/her wrist and fingers. Monitoring of motor block will be assessed by Modified Bromage Score . Complete motor block will be recorded when no voluntary movement will be possible.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lidocaine, atracurium and Mg sulphate in people with Postoperative Pain, run by Assiut University at 2 sites in Egypt.

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 2 inclusion and 11 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 12 Jun 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 Egypt. 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 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?

postoperative analgesia (time frame: 24 hour). 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 12 Jun 2018.
