Impact of an extrafascial versus intrafascial injection for supraclavicular brachial plexus block on respiratory function: a randomized, controlled, double-blind trial.

Introduction: Hemidiaphragmatic paresis after ultrasound-guided supraclavicular brachial plexus block is reported to occur in up to 67% of patients. We tested the hypothesis that an injection outside the brachial plexus sheath reduces the incidence of hemidiaphragmatic paresis compared with an intrafascial injection while providing similar analgesia.

Methods: Fifty American Society of Anesthesiologists I-III patients scheduled for elective upper limb surgery received a supraclavicular brachial plexus block using 30 mL of 1:1 mixture of mepivacaine 1% and ropivacaine 0.

[Flexible bronchoscopy: contribution of the anesthesiologis].

The field of interventional pulmonology is expanding rapidly with increasingly complex endoscopic procedures. Pulmonologists and anesthesiologists are both airway specialists. When they cooperate in performing flexible bronchoscopies, they must share a common anatomical space.
