Colleague did procedure in hypertensive patient.
Patient admitted to hospital the next day with stroke like symptoms.
Another partner did esi. Didn't see hgA1C a week before was 9+ (I'm not in office so I can't look up exact numbers).
Patient admitted to hospital couple of days later with BGs of 600+, admitted to icu for ketoacidosis.
It's a balancing act. Don't check if that is your wont but don't be surprised when something bad happens.
And the high BP is not an indication that patient has to go to ER. But there is good anesthesia evidence that hypertensive patients have increase complications with surgery. That is the reason to reschedule procedures.
