Effect of a Bolus of Clonidine Systemically Administered on the Excitability of the Spinal Motoneurons of the Lower Extremity — EXCICLON

Pain Management Clinical Trial

Official title:
Monocentric, Prospective Randomized Controlled Clinical Trial Assessing the Effect on the Lower Limb Spinal Motoneuron Excitability, the Efficacy in Term of Morphinic Sparing and Safety of of Early Clonidine Bolus Intravenous Administration During General Anesthesia in Children and Adolescent 6-18 Years Old Requesting Reconstructive Tympanic Surgery

Clinical Trial Summary

The purpose of this study is to assess the effect of IV clonidine administration on lower limb spinal motoneuron excitability during standardized total intravenous anesthesia (propofol and remifentanil).

Clinical Trial Description

According to the literature data, intraoperative administration of clonidine reduces the need for morphine per and postoperative and thus reduces the side effects associated related to their administration.

Nevertheless, on the basis of current knowledge, clonidine may disrupt some electrophysiological measures required for the intraoperative monitoring of surgeries with a high risk of neurological complications.

For such surgery, anaesthesiologists are led to inject clonidine after surgery, at a time when the electrophysiological measures are no longer needed, which limits the benefit in terms of intraoperative morphine savings.

Whith this study, investigators would like to investigate if an early administration of clonidine in patients aged 6 to 16 years undergoing ear surgery disturbs excitability of the spinal motor neuron.

The choice of the study population is justified by the fact that the ear surgery does not require electrophysiological monitoring and it is carried out under conditions similar to that of anesthesia of scoliosis corrective surgery for which electrophysiological measurements are essential for the prevention of neurological complications.

Observations will allow investigators to determine therefore whether early administration of clonidine is possible at high risk of neurological complications surgeries for which electrophysiological monitoring is essential. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
