I was diagnosed July 2012 with POTS and had to have my gallbladder removed the end of October of 2012. I ended up in the ICU because my vitals were so out of wack the surgery would not be safer until I was stable. I told my surgeon the articles I had read about POTS patients having issues with anathesia so he was worried and did some research of his own. I was very lucky because he educated the anathesiologist and had my cardiologist in the operating room just in case. He said my heart rate was fast but with some meds they were able to control it. The day I was put in ICU my heart rate dropped to 32 and I passed out and woke up with pacer pads, very scary! I didnt have the surgery until 4 days after that when they knew it was safe. Knowledge is everything, had I not known POTSies have trouble with anathesia it could have been a different outcome. I have had 5 surgeries prioir to POTS and never had issues. DO research on anathesia and POTS educate whoever is doing the procedure!
