Drug Approved To Treat Rare Disorder Associated With Anesthesia

“When a patient experiences malignant hyperthermia during surgery, it is a life‐threatening emergency requiring immediate treatment including the administration of the ‘antidote’ drug dantrolene sodium,” said Henry Rosenberg, MD, CPE, a founder and President of the Malignant Hyperthermia Association of the United States (MHAUS). “The ability for healthcare professionals in hospitals and surgery centers to more quickly prepare and administer this new formulation of the antidote dantrolene sodium is expected to bring the crisis under control more rapidly and prevent severe complications from MH.” Source: MHAUS

But for the first time, researchers are looking at how oxidative stress and inflammation caused by the conditions of spaceflight affect those hearts for up to five years after [...]

New research from the Monell Center reveals that simply believing that an odor is potentially harmful can increase airway inflammation in asthmatics for at least 24 hours following exposure.
