About this study
The simplicity of the implementation and the effectiveness of hypno-analgesia (via the magic glove technique) has already been proven in some research work, during the installation of peripheral venous route. An unpublished preliminary study has shown that this method appears to be the most effective in preventing pain during pediatric propofol injection.
The purpose is to compare the effectiveness of hypno-analgesia of the hand by the "magic glove technique" to lidocaine used in an extemporaneous mixture in the prevention of pain with injection of propofol during intravenous induction in children aged 7 to 14 years
Read the detailed description
Propofol is a hypnotic of choice, because of its speed of action, its dose-effect relationship (allowing titrated inductions), its anti-emetic effect, as well as its delay and its short duration of action. Among its side effects, the pain during its injection occupies a significant part in pediatrics (60% in adults, up to 85% in children).
It is most often described as an unpleasant sensation, discomfort or even a burn at the point of puncture, going up along the path of the vein and can extend to the whole arm. The mechanism of this pain is still poorly understood at this time. Several mechanisms have been mentioned such as activation of the bradykinin cascade, a direct stimulation of the free nociceptive venous nerve endings.A meta-analysis concludes in adults that the two most effective techniques are a puncture site on the ulnar vein and a pretreatment of the vein by Lidocaine. In children, the anatomical differences, the notion of protection of the venous capital from the first vascular approach, whatever the prognosis of the patient and the competence of the operator will influence the choice of the material, the choice of the site and the puncture technique. Several pediatric studies have attempted to reduce this injection pain by other techniques. A panel of products has been tested with different drug orientations or not. The suggestion centered on analgesia of the hand is a powerful technique, adapted to acute pain. The pain sensation will thus be partially or completely replaced by a sensation of a different nature, thus attenuating the nociceptive process. This technique has not been studied during injection with propofol.
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Magic glove hypnosis techniqueProcedure or surgery
Realization of the magic glove hypnosis technique by an expert physician trained in hypnosis, according to a classic discourse before : intravenous infusion with 1% propofol (3 mg/kg with 600 ml / h electric syringe pump). Use and dose in accordance with the SPC.
lidocaineDrug
intravenous infusion with an extemporaneous mixture of 18 volumes 1% propofol (180mg) for 2 volumes of 1% lidocaine (2ml) with 600 ml / h electric syringe pump. Use and dose in accordance with the SPC.
| Study group | Role | What they receive |
|---|---|---|
| magic glove hypnosis | Experimental | Magic glove hypnosis technique use before propofol infusion Receives: Procedure: Magic glove hypnosis technique |
| lidocaine | Active comparator | extemporaneous mixture with lidocaine for propofol infusion Receives: Drug: lidocaine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain Intensity Score: Cameron Type Scale
The reactions of the child from the beginning of the injection are filmed by an outside observer.
At the end of the 3 mg / kg, the observation is stopped. From a distance, a member of the Children's Hospital Pain Unit will blindly display, by viewing child-centered videos, a pain score, according to Cameron's score [0 = No pain ( no reaction); 1 = slight pain (grimace); 2 = Moderate pain (grimaces + cries / moans); 3 = severe pain (crying / crying + hand removal).].
A score greater than or equal to two represents a significant pain at induction.
Measured: Day 1
Secondary outcomes (1)
Satisfaction assessment
Evaluation of the satisfaction as soon as the child is able to leave the post interventional surveillance room (sspi) by an analog evaluation scale of the degree of satisfaction. A score ≤ 7 expressing dissatisfaction on his part, the reasons for this possible discontent will then be requested. Then, we will ask him, in case he should be asleep, if he wants us to proceed in the same way.
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Magic glove hypnosis technique and lidocaine in people with Pain, run by University Hospital, Toulouse 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 4 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 28 Nov 2025. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Pain Intensity Score: Cameron Type Scale (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03453723, which also lists 6 linked publications.
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 28 Nov 2025.
