Methylene blue dye has an important role in lymphatic mapping for sentinel lymph node surgery. A recent safety announcement from the US Food and Drug Administration warned physicians about possible serious central nervous system reactions in patients on serotonergic medications who received intravenous methylene blue for the identification of parathyroid glands. This report summarizes evidence from the Food and Drug Administration's announcement and methylene blue pharmacokinetics. The authors conclude that the use of methylene blue dye at low doses for lymphatic mapping likely carries very little risk for serotonin neurotoxicity, although breast surgeons should be aware of this potential complication in the event of mental status or neuromuscular changes in patients after lymphatic mapping.

High-dose perioperative corticosteroids in steroid-treated patients undergoing major colorectal surgery: necessary or overkill?
Steroid-treated patients undergoing major colorectal surgery are routinely treated with high-dose steroids (HDS) to prevent perioperative adrenal insufficiency and cardiovascular collapse. However, there is no evidence to support this practice. ⋯ Steroid-treated patients with inflammatory bowel disease undergoing major colorectal surgery appear to have no clinically significant hemodynamic instability when managed with LDS versus HDS. A prospective study assessing perioperative steroid dosing in patients with inflammatory bowel disease is in progress.
