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.
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.

In this conventional procedure group, the anesthetic solution is administered subcutaneously and by infiltration into the surgical area. A maximum volume of 20 ml (dose dictated by the operation) of the solution is thus injected by the operator: Lidocaine 10mg/mL combined with adrenaline 0.005mg/mL administered at a dose of 10 to 20 mL, i.e. a total of 50 to 200 mg of lidocaine.
In this experimental procedure group, the anesthetic solution is administered subcutaneously and by infiltration into the surgical area. A maximum volume of 20 ml (dose dictated by the operation) of the solution is thus injected by the operator: Lidocaine 10mg/mL combined with adrenaline 0.005mg/mL administered at a dose of 18 mL + ropivacaine 7.5 mg/mL 2 mL or 15 mg. For a total of 20 mL: lidocaine 9mg/mL, ropivacaine 0.75 mg/mL, adrenaline 0.005 mg/mL

Experimental group: experience of patients in the Lidocaine + Ropivacaine group
The postoperative experience will be evaluated by the Quality of Recovery questionnaire (QoR-40) at 48 h postoperative. This questionnaire includes sections on comfort, pain, support, emotions and physical independence. Each section has questions to be answered on a scale of 1 to 5 in which 1 = very poor and 5 = excellent.
Time frame: 48 hours after surgery
Control group: experience of patients in the Lidocaine alone group
The postoperative experience will be evaluated by the Quality of Recovery questionnaire (QoR-40) at 48 h postoperative. This questionnaire includes sections on comfort, pain, support, emotions and physical independence. Each section has questions to be answered on a scale of 1 to 5 in which 1 = very poor and 5 = excellent.
Time frame: 48 hours after surgery
Pain on a numerical visual analog scale : Experimental group
Pain will be evaluated on a numerical visual analog scale in the experimental group. The scale ranges from 0 to 10 in which 0 = no pain and 10 = worst possible pain.
Time frame: Day 0

Neuropathic pain according to the DN4 questionnaire: Experimental group
Pain in the experimental group will be evaluated by telephone using the DN4 questionnaire. This is a clinician-administered questionnaire consisting of 10 items. Seven items related to pain quality (i.e. sensory and pain descriptors) are based on an interview with the patient and 3 items based on the clinical examination. The DN4 (which stands for Douleur Neuropathique 4 i.e. Neuropathic Pain 4) is one of the questionnaires that can be useful in diagnosing neuropathic pain. It was initially written in French but immediately translated into English by the same team. The scale has been widely used since 2005 due to its simplicity. It evaluates neuropathic pain following central and peripheral neurological lesions. It is also used for diagnostic purposes, allowing the clinician to determine whether the pain is of neuropathic origin.This questionnaire has been well validated by a number of studies.
Time frame: At 3 months
Satisfaction with perioperative management: Experimental group according to the EVAN-LR questionnaire
Patient satisfaction with perioperative management will be evaluated using the EVAN-LR (Evaluation du Vécu de l'Anesthésie LocoRégionale = Assessment of the Experience of Locoregional Anesthesia) self-reported questionnaire. This questionnaire, which specifically assesses the satisfaction of patients undergoing regional anesthesia, comprises 19 items, structured in a global index and five dimensions: Attention, Information, Discomfort, Waiting, and Pain. The consequences of staying alert during regional anesthesia are specifically addressed by two items.
Time frame: Day 0
