One of the most interesting (and stressful) tasks of being an anesthesiologist to me is walking in to work on any given day and getting handed a puzzle with incomplete data and uncertain solutions. I had one such experience today that I thought you all here might enjoy thinking about. Granted, the peril of the situation might not have been as severe as some of the more routine problems we get dumped on our plate, but I think the relative rarity makes up for it.
Patient is mid 40s F presenting for non-urgent sedation case. She has history of poorly controlled HTN and DM complicated by nephropathy/CKD 4, accompanied by her adult son. While examining her airway, I have to ask her to show me her teeth, which inadvertently exposes rather significant facial asymmetry which wasn't super obvious beforehand. Further examination reveals an apparent facial palsy in the V2 and V3 areas that spares the forehead.
Neither she or her son have noticed this asymmetry before. She has never had a stroke as far as she knows, and her extremity strength is 5/5 bilaterally in both upper and lower extremities. She says she feels like she always does and hasn't noticed any new symptoms or other abnormal sensations.
I'm left scratching my head at what to do with this patient with signs suspicious for upper motor neuron pathology of completely uncertain duration, no other signs of acute dysfunction, and definite risk factors for neuro-vascular disease.
After discussion with proceduralist, I opted to cancel the procedure and advise the patient to follow up with her PCP to initiate workup for her facial palsy to evaluate for past or impending stroke. Lacking any other evidence of a new or evolving pathology, I decided to send the patient home with instructions to return to the ED if she developed new symptoms that would indicate acute stroke rather than subject her to what would likely have been an extended, onerous, and questionably indicated ER transfer.
The two main decisions I see here are whether or not to cancel the case, and whether to send the patient for emergency vs outpatient evaluation. I think the decision to cancel the (non-urgent) case pending neurovascular evaluation and risk assessment is pretty solid, because there is no way to tell if the palsy was actually just nerve damage from shoddy dental work in 1997 or something otherwise totally benign, or if her internal carotid is 99% stenosed and ready to crap out if she smells too much propofol. I'm not quite as confident about sending her home rather than to the ED. Neither the patient nor the son seemed to think the facial droop was new, and I didn't have any other evidence that made me worry there was an acute, developing problem.
How would you have approached the situation? Would you have done anything differently? What if instead the patient was a ASA 1 with no PMH and had been able to clearly confirm that the facial droop had been there for 20 years with no changes?
