I dont believe thats contraindication to nerve block. If its already paralyzed on the same side of the shoulder surgery and you dont have respiratory problems with that. However if it is on the other side of the rotator cuff surgery its better to avoid interscalene block since it can cause temporal phrenic nerve block with contralateral diaphragmatic paralysis. In that case you will have bilateral paralysis and might experience respiratory problems. But there are alternatives to interscalene block that would spare phrenic nerve and anesthetise shoulder at the same time. You just need to discuss the issue with your anesthesia provider.
