About this study

Official title: Axillary Block in Association With Analgesic Truncal Blocks of the Median and Radial Nerves at the Elbow for Wrist Surgery.

Fractures of the forearm bones that occur around the wrist are common in the elderly. Standard anesthesia for its surgical treatment is regional anesthesia (RA): supraclavicular block, infraclavicular block or axillary block (BAX). However, these techniques have some limitations, such as the postoperative pain management and the non-specificity of the analgesia. Indeed analgesia is not specific to the wrist and extends to the elbow and forearm, preventing rapid recovery of elbow flexion and extension when a long-acting local anesthetic (LA) is used. Recently RA techniques associating proximal anesthetic blocks with distal analgesic blocks have been proposed to serve a dual objective: good anesthesia for surgery and specific analgesia.

The hypothesis of this study is that, for the wrist surgery, axillary block using a short-acting LA combined with analgesic blocks at the elbow using a long-acting LA could provide a RA installation time reduction, an optimal surgical comfort, a longer post-operative analgesia duration and a faster recovery from motor block.

Read the detailed description

This multicenter, prospective, randomized, open-Label study compares two techniques :

  • BAX (usual technique) : Axillary brachial plexus block (Axillary block) with a long-acting LA (Ropivacaine)
  • BAX-Asso (experimental technique) : Axillary brachial plexus block (Axillary block) with a short-acting local anesthetic (Lidocaine) + Analgesic block at the elbow with a long-acting local anesthetic (Ropivacaine) Every block will be performed under Ultrasound. BAX will be performed using a multi-injection technique at contact with median (nM), radial (nR), ulnar (nU), musculocutaneous (nMC) and medial antebrachial cutaneous (nCMAB) nerves. 15-30 mL of LA will be injected.

Analgesic truncal blocks of the median and radial nerves will be performed at the elbow. 3-7 mL of LA will be injected.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Level of pain when the patient recovers the flexion of the forearm on the arm

    Pain VRS ranging from 0 to 10 (0=no pain, 10=worst possible pain)

    Measured: 24 hours

Secondary outcomes (9)
  1. Duration of motor block at the elbow

    Time between the performance of regional anesthesia and the elbow flexion recovery

    Measured: 24 hours

  2. Axillary block success

    Assess of motor block and sensory perception to pin-prick in the distribution of the five terminal branches at 10, 20, and 30 minutes postinjection.

    Motor block: complete (2=paralysis), partial (1=paresis), or none (0). Motor function assessed in the following manner: wrist and finger flexion (median nerve), wrist and finger extension (radial nerve), thumb adduction and flexor carpi ulnaris flexion (ulnar nerve), and biceps flexion (musculocutaneous nerve).

    Sensory block: complete/anesthesia (2=loss of sensation to pinprick), partial/analgesia (1=dull sensation to pinprick), or none (0=sharp sensation to pinprick).

    Sensory distribution assessed in the following areas: thenar eminence and thumb tip (median nerve), dorsum of hand (radial nerve), fifth digit fingertip (ulnar nerve), lateral aspect of forearm (musculocutaneous nerve) and medial aspect of forearm (medial antebrachial cutaneous nerve).

    Successful blockade is defined by a sensory-motor score ≥ 3.

    Measured: 40 minutes

  3. Feasibility of the wrist surgery

    Usage (or not) of an additional anesthetic procedure to perform the surgery

    Measured: 2 hours

  4. Duration of postoperative analgesia

    Time between the performance of regional anesthesia and the first dose of rescue analgesia with opioides.

    Measured: 72 hours

  5. Postoperative morphine consumption

    Cumulated dose of oxynorm (mg)

    Measured: 48 hours

  6. Sleep quality

    Incidence of sleep disorders

    Measured: Day 2 After Surgery

  7. Complications during block performance

    Incidence of vascular puncture, paresthesia, intraneural injection and intravascular passage

    Measured: 15 minutes

  8. Complications immediately after block

    Onset of vertigo, nausea or vomiting

    Measured: 2 hours

  9. Postoperative complications

    Questionnaire about potential sensory anomalies such as numbness, itching or tingling

    Measured: Day 15 After Surgery
