Im a new grad in an OR Residency program. I've been feeling light headed and had to excuse myself during a few procedures. I wanted to ask if this is something that people new to the OR experience or is this me. I don't know why I react this way and am scared it's something that I can't correct. On some procedure, I was able to scrub/assist in retracting without any problems, usually the short procedures but the times that I felt weak and light headed occurred during a toe removal and a hernia repair. For the hernia repair, I didn't feel light headed until the procedure was almost over. Any suggestions would be appreciated. Thank you!
