Nausea-Killer Causes Bleeding
After a tonsillectomy, it seems patients are caught in a Catch-22. New research shows a commonly used steroid to reduce nausea and vomiting is associated with an increased risk of postoperative bleeding.
About 186,000 tonsillectomies are performed each year in the United States, making the outpatient procedure one of the most frequently performed surgical procedures in children. Dexamethasone injected after the start of anesthesia can reduce the nausea and vomiting often experienced after surgery. But researchers say the proper dosing remains unclear, as are the steroid's adverse effects, including bleeding.
"Dexamethasone, possibly through inhibition of wound healing, increases the risk of postoperative bleeding in this specific setting," study authors write.
