Outcome Measures

Primary Outcomes (1)

  • incidence of severe postoperative rebound pain

    Rebound pain after PNB is defined as a Numerical rating Scale of 7 or more.

    from surgery to 30 days post operation

Secondary Outcomes (1)

  • To measure the impact of ketamine on the level of "rebound pain" in patients with central sensitivity using the Numerical Rating Scale

    from surgery to 30 days postoperatively

Study Arms (2)

Study drug

ACTIVE COMPARATOR

Drug: Ketalar, 5 mg/mL Injectable Solution

Placebo

PLACEBO COMPARATOR

10 mL 0.9% saline after the realization of PNB, before tourniquet set up and beginning of surgery

Other: Placebo

Interventions

The patients will receive (slow intravenous injection) 0.3 mg/kg intravenous ketamine diluted by the pharmacy department into 10mL saline after the realization of PNB but before tourniquet set up and before start of surgery.

PlaceboOTHER

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.
