Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Risk factors and Prevention of severe Pain upon cessation of a peripheral nerve block. A prospective randomized study in ambulatory patients undergoing upper limb bone surgery under single shot axillary plexus block.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Pain in the course of upper limb bone surgery is a major source of discomfort for patients during postoperative time.

Severe post-operative pain is a risk factor for chronic pain. Use of a well-known molecule, regularly used in anesthesiology. Prospective double-blind study on 120 patients. Pain rebound upon awakening of the axillary plexus during upper limb bone surgery is a frequent phenomenon in post-operative follow-up of patients.

The anti-hyperalgesic properties of ketamine could be a benefit against this effect.

No studies have combined intravenous ketamine with localoregional anesthesia to reduce pain upon its release.

This may improve patients' post-operative comfort. The patients will be randomized in 2 groups and allocated to receive (slow intravenous injection) either 0.3 mg/kg intravenous ketamine diluted into 10mL saline or 10 mL 0.9% saline after the realization of PNB, before tourniquet set up and beginning of surgery.

Group Type ACTIVE_COMPARATOR

Ketalar, 5 mg/mL Injectable Solution

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type OTHER

The patients will receive 10 mL of 0.9% saline. This injection is also performed after the realization of PNB but before tourniquet set up and before start of surgery.
