When performing an SGB, we expect a temporary condition referred to as “Horner’s syndrome” to occur- your right eyelid will be droopy, your right pupil will be smaller than the other pupil, and the white part of your right eye may get red. This is a normal part of the block and will wear off in 4 to 8 hours.
In about 20% of the cases, patients also experience a “hoarse voice” or feel as if something is in the back of their throat. This happens sometimes and it is temporary. If this happens, take a few careful sips of water and make sure you are swallowing normally. The SGB has few additional side effects. Patients may report mild soreness at the site of injection that is temporary and will not require any treatment. Any additional risks or concerns will be discussed with the physician prior to the procedure.
