Official title: Evaluation of Postoperative Experience of Two WALANT-type Modes of Anesthesia (Lidocaine Alone or Combined With Ropivacaine) Used in Ambulatory Surgery of the Upper Limb. A Single-center Prospective Randomized, Single-blind Study

Status Completed

Clinical Trial Summary

Distal surgery of the upper limb under local anesthesia using the WALANT technique (Wide Awake Local Anesthesia No Tourniquet) has become the standard care in orthopedic surgery. The principle is that the operator infiltrates the whole surgical area with a 1% lidocaine solution combined with adrenaline (diluted to 1/200,000) so that all distal surgery of the upper limb can be performed without a tourniquet. Thus, the perioperative course and management of the patient in the operating room and the constraints inherent to general anesthesia are largely reduced. Also, the material cost is considerably reduced. However, WALANT often induces significant pain when the patient leaves the operating room to return home. This effect is related to the pharmacological formulation of lidocaine which has a short half-life (< 3h). To reduce this inconvenience of early block removal, adding a local anesthetic with a longer duration of action (ropivacaine) to lidocaine would extend the duration of the analgesic, improving postoperative experience and satisfaction. The main objective of this research is to evaluate the effect of two WALANT anesthesia protocols (with or without the addition of ropivacaine) on the postoperative experience of patients (QoR-40 questionnaire) 48 hours after outpatient hand surgery.

Clinical Trial Description

Secondary objectives include the evaluation of short-term pain (Day 0 to Day 7), chronicisation of pain at 3 months, patient satisfaction regarding perioperative management and tolerance in both groups.

This is a monocentric, prospective, randomized, single-blind study. 80 adult patients, eligible for outpatient surgery under under WALANT for hand surgery such as carpal tunnel, stub finger, Dupuytren's disease or elbow surgery such as ulnar nerve compression and lacertus fibrosus syndrome, will be recruited during their care in the orthopedic and trauma surgery department at Nîmes University Hospital over an estimated period of 12 months. After receiving information, the intervention visit will be planned within 21 days. After collecting consent and checking the selection criteria, patients will be randomized (1:1 stratified according to hand/elbow surgery) for a procedure under WALANT anesthesia with 10 to 20 ml of 1% lidocaine (10 mg/mL) (depending on the procedure) combined with adrenaline (0.005mg/ml) with or without the addition of 15mg ropivacaine. An evaluation of the pain via a visual analog scale (0 to 10) will be carried out before discharge from the service and by telephone on Day 1 according to the current care then at Days 2 and 3 and 7 for the research. The patients will also have to answer questionnaires on their perioperative management (Evaluation of the experience of local anaesthesia or EVAN-LR) before leaving the department and then on the postoperative experience (Quality of Recovery or QoR-40) at D2 and the possible "chronicisation" of pain at 3 months (neuropathic pain or DN4) by telephone. Possible adverse events will be collected up to D7. ;
