this is my first pregnancy and i've worked in a stepdown unit for a few years now and never get queasy or dizzy or anything... but about a month ago (i was about 14 weeks) i tried to hold pressure on a groin to pull a sheath and i got too dizzy and hot and nauseous so another nurse had to take over for me... then last week (19 weeks) i had a patient with a central line being placed. it took forever for the CRNA to get the line in and i started again feeling dizzy and hot....again had to call another nurse to standby to assist.... i am worried, has this happened to anyone else?? i sure hope this stops after the baby comes!!!
