hi,
its really difficult situation.it all depends what sort of anaesthesia you are giving.more common in regional blocks compared to spinal,epidural anaesthesia & gas anaesthesia which is associated with least tourniquet pain manifested by hpertension ,tachycardia etc.it also depends on intensity & level of regional anaesthetic block.choice of local anaesthesist & spplementation of block with opioids also matters a lot.if deepening of anaesthesia & substantial analgesia also doesn't relieve the pain then last resort is deflation of cuff which will immediately relieve the pain & hypertension.
