though i do not claim to be anesthetist or anesthesiologist, you may want to bring this to the attention of either the nurse anesthetist or anesthesiologist(both), depending what type of surgery and other patient factors depends on if they will give general anesthesia or a local MAC..they WILL ask you about any current drugs you are taking long before you are in the preoperative holding area on the day of your surgery(i am guessing this is some sort of same day surgery/ambulatory surgical center). since many AAS are protein bound in the blood( ie. albumin, and SHBG), maybe an IV agent administered by the anesthetist also uses albumin to be distributed around the body( therefore an increase in the amount of free drug(active) that he administers...many AAS have also been shown to sct with enzyme CYP3A4 in the liver maybe prolonging the half life of administered anesthetic agents. There is also another factor.. if you are currently on AAS when they do surgery (depending on what type of surgery) skin may be stretched out due to you being pumped up and muscular( when the surgeon, surgical asistant, and/or RNFA decide to suture you back up using staples, and sutures your healing and surgical site is at risk for distortion if you come off steroids in the future because you may have some loose skin when you come off. Then there is the whole issue of clotting factors and your PT may be elevated or your RBC, Hgb, and Hct may be high causing you to clot and maybe there is also an increase in blood pressure form the roids that may predisposition you to hematoma formation..
alll in all the answer is to tell the anesthesiologist....at least they can prepare for adverse reactions in the OR..
i did not go into detail about the anesthetic agents via endotracheal tube. cevoflurane, isoflurane etc..
