[Complication and Anesthetics-induced Toxicity of Stellate Ganglion Block]
Abstract:
Stellate ganglion block (SGB) is a commonly used safe procedure. In rare cases, it is associated with life- threatening complications [retropharyngeal hematomas (RPH), local anesthetics-induced toxicity, et al.). Man- agement and preventive measures of these complica- tions are described. RPH after SGB necessitates emer- gency airway management Intoxication is mainly the result of accidental intra- arterial injection and is difficult to treat but higher doses of intravenous lipid emulsions can improve the outcome.
