The multiple injection technique for axillary block provides faster readiness for surgery compared to single injection, despite a longer block performance time. This method ensures quicker patient preparation for procedures by reducing block latency and improving analgesia spread.

Area of Science:

  • Anesthesiology
  • Regional Anesthesia
  • Surgical Preparation

Background:

  • Axillary block is a common regional anesthesia technique for upper limb surgery.
  • Optimizing the timing of surgical readiness after axillary block is crucial for efficient operating room workflow.
  • Assessing the impact of different injection techniques on block performance and latency is important for clinical practice.

Purpose of the Study:

  • To prospectively compare the time to readiness for surgery between single and multiple injection techniques for axillary block.
  • To evaluate block performance time, block latency, and the need for supplemental analgesia in both techniques.
  • To determine the overall effectiveness and safety of each axillary block technique.

Main Methods:

  • Prospective assessment of 80 patients undergoing axillary block using either single or multiple injection techniques.

  • Brachial plexus identification via nerve stimulator, with anesthesia administered using mepivacaine 1% with adrenaline.
  • Sensory block assessment every 10 minutes, with supplementation if needed; readiness for surgery defined by complete analgesia in the operative areas.

    • Main Results:

    • Single injection had shorter block performance time (5.5 min vs 9.5 min), but longer block latency (33 min vs 15.5 min) and higher need for supplementation (57% vs 7%).
    • Multiple injections resulted in faster overall readiness for surgery (25 min vs 38.5 min).
    • Block effectiveness was high in both groups (100% vs 98%), with similar adverse event rates and no neurological sequelae.

    Conclusions:

    • While single injection is quicker to perform, the multiple injection technique for axillary block leads to faster patient readiness for surgery.
    • The improved readiness with multiple injections is attributed to shorter block latency and better spread of analgesia.
    • Both techniques are effective and safe, but multiple injections offer a clinical advantage in terms of surgical preparation time.
