NCT05734469

Brief Summary

This is a monocentric, comparative prospective randomized controlled trial. Patients will be randomised into 2 groups and will receive either a sciatic popliteal nerve block or an ankle block (single dose locoregional block injection before the surgery) for elective forefoot surgery in addition to general anaesthesia. The study will:

  • Compare the occurrence of rebound pain and its recovery between a peripheral nerve block of the popliteal sciatic nerve and an ankle block in patients undergoing lower limb (forefoot) bone surgery under general anaesthesia combined with a PNB achieved in preoperative single injection.
  • To identify the role of the type of nerve fibers anesthetized and the local inflammatory process in rebound pain development.
  • Assessing the amount of the local sympathetic block induced by the locoregional anesthesia could be used a non-invasive predictive indicator of the occurrence of rebound pain depending on the nerve fibers involved (purely sensitive versus sensitive and motor).

Outcome Measures

Primary Outcomes (1)

  • Difference in the occurrence of rebound pain according to the type of PNB

    The investigators wished to prospectively evaluate and compare the incidence of the occurrence of RP, in the context of popliteal sciatic nerve PNB (sensory-motor block) and in the context of distal ankle PNB (pure sensory block). RP was defined in this study as severe pain with a Numerating Rating Scale of Spasticity (NRS) score ≥ 7/10 within the first 24 hours after performing the PNB.

    Through study completion, an average of 1 year

Secondary Outcomes (2)

  • The importance of the local sympathetic block induced by the locoregional anesthesia as well as the type of anesthetized nerve fibers in the rebound pain process.

    Through study completion, an average of 1 year

  • Predictors of Pain Rebound in the Context of Forefoot Surgery with BNP

    Through study completion, an average of 1 year

Study Arms (2)

Popliteal sciatic nerve block

OTHER

A local anesthetic solution of 30ml of ROPIVACAINE 0,5% (4mg/kg maximum) will be used for the popliteal sciatic nerve block (popliteal sciatic, saphenous) by real-time ultrasound guidance (associated with a standardized general anesthesia)

Other: Forefoot bone surgery

Ankle block

OTHER

A maximum solution of 15ml of ROPIVACAINE 0. 5%( 4mg/kg maximum) for the ankle block (saphenous, superficial peroneal, deep peroneal and tibial nerves) by real-time ultrasound guidance (associated with a standardized general anesthesia)

Other: Forefoot bone surgery

Interventions

Elective forefoot bone surgery under popliteal sciatic nerve

Popliteal sciatic nerve block
