Hello,You may be able to get away with removing just one or two nails but generally this is required so that your oxygen and heart rate can be monitored during surgery. Ask your Plastic Surgeon as they'll know your situation the best.Take care
In my practice, my board certified anesthesiologist's policy is to remove them and/or nail polish.Check with your board certified plastic surgeon for his/her policy.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA
