Bloqueos nerviosos bajo ultrasonido

Advantages and disadvantages of ultrasound guided

Advantage of ultrasound guided regional anesthesia methods.

  • High success rate
  • Safe performance of blocks
  • Direct visualization of neuronal and adjacent anatomical structures
  • Direct visualization of needle placement and spread of local anesthetics
  • The individual blocks are cheaper in comparison with other techniques in regional anesthesia
  • Amortization of high standard ultrasound equipment after 2500 blocks due to high success rates (with very low conversion rates to alternative anesthesia methods),
Bloc interscalénique

Interscalene block for necrotising fasciitis surgery in ASA IV patient


Regional anaesthesia is presented as an alternative to general anaesthesia offering better control of postoperative pain and a shorter anaesthetic recovery time, although not without complications. These benefits are of great importance in patients with high comorbidity where general anaesthesia may pose a high risk.

The brachial plexus block at interscalene level is one of the most commonly used techniques for upper limb surgery.
