Case Reports[Hypoglossal nerve neuropraxia after shoulder hemiarthroplasty].
We report a case of hypoglossal nerve damage after shoulder hemiarthroplasty with the patient in "beach chair" position, performed with general anesthesia with orotracheal intubation, and without complications. An ultrasound-guided interscalene block was previously performed in an alert patient. ⋯ Mechanisms such as hyperextension of the neck during intubation, endotracheal tube cuff pressure, excessive hyperextension, or head lateralization during surgery have been described as causes of this neurological damage. We discuss the causes, the associated factors and suggest preventive measures.
