First off, a little about me. I'm a 21 year old female who was diagnosed with vasonotor instability 3 years ago. My cardiologist told me to just increase my fluids and sodium to keep my blood pressure up and prevent me from passing out when standing up. However throughout my 12 hour nursing clinicals i had multiple near syncope moments from standing too long. But of course i fell in love with surgery...which made me nervous (the last place i would want to pass out is in the OR). So I began a perioperative program 2 weeks ago and had my first clinical last Monday. I drank a ton of water, and ate plenty of salty chips in the days leading up. I also wore TED hoses during my clinical. About an hour and a half of being scrubbed in during a lap hysterectomy, that dreaded feeling hit me. I felt hot, sweaty, nauseous, and was beginning to feel confused. I shifted around my weight, bent my knees, flexed my legs, but nothing was working. So I told my preceptor and she had the circulator immediately sit me down and ungown me. I was so embarrassed, but the surgeon and nurses were all very nice about it and told me all their near syncope moments in the OR. they say my body will get used to standing for long time periods in a hot mask and gown. I just wonder if I'm strong enough to be able to handle the OR. It really puts a damper on my experience. Anybody have any tips on how to avoid near syncope? And how to increase my "standing stamina"?
