Increased Blood Pressure and Loss of Consciousness after Stellate Ganglion Block: A case report

ABSTRACT

A 59 year-old female patient suffered from complex regional pain syndrome in left hemiplegia, was managed to stellate ganglion block (SGB) with 5 ml of 1 % lidocaine. The SGB was performed twice previously, with no side effects. And the third SGB was done in the same manner after negative aspiration testing. Two minutes later, she developed respiratory difficulty with increased blood pressure. Immediately airway management was performed by mask ventilation with oxygen. But ten minutes later, she developed respiratory arrest with unconsciousness and intubation was performed. Soon she recovered spontaneous respiration and the blood pressure returned to the former level. Despite taking all precautions during SGB, complications such as respiratory arrest and hypertension may occur even in the hands of an experienced physician. Therefore, before starting SGB, all resuscitation drugs and equipment must be ready for use in case any emergency develops.
