Anesthesia disrupts neural microanatomy to alter consciousness

September 9, 2019 | Anesthesiology News

Anesthesia-induced loss of consciousness is accompanied by microscale changes in neural signaling patterns, according to a recent study. The results highlight the role of local network dynamics in managing conscious states. General anesthesia produces medically induced loss of consciousness (mLOC), and its implementation is fundamental to modern surgical practice. Despite the importance of mLOC, the physiologic processes underlying loss of consciousness remain unclear. Current theory suggests that a key prerequisite for consciousness is the brain’s ability to select one set of sensory input while rejecting alternatives. Research supporting this theory has identified a collection of “resting states”—patterns of cortical activity that may represent these discriminable sets of sensory inputs.

Looming anesthesiologist shortage fuels high market demand

August 13, 2019 | Anesthesiology News

It’s a familiar tale of inexorable demographics and health trends: the rapid graying of America, the growing chronic disease burden, and the exodus of physicians and nurses from the baby boomer generation into retirement, thus fueling a health care worker shortage that will mushroom over the next two decades. The story translates into impending recruitment challenges for medical practices and institutions across the sector to meet the large and still-growing demand for medical care, including surgery—with its attendant anesthesia services—to serve a burgeoning population of older, sicker patients.

Marijuana use may affect patient anesthesia

August 2, 2019 | Pain News Network

When Colorado legalized marijuana, it became a pioneer in creating new policies to deal with the drug. Now the state’s surgeons, nurses and anesthesiologists are becoming pioneers of a different sort in understanding what weed may do to patients who go under the knife. Their observations and initial research show that marijuana use may affect patients’ responses to anesthesia on the operating table — and, depending on the patient’s history of using the drug, either help or hinder their symptoms afterward in the recovery room.

In Joint Statement, ASA Backs Need for Anesthesia Provider in Pediatric Dental Procedures

July 30, 2019 | Anesthesiology News

An additional, well-trained professional who is capable of providing anesthesia and managing a patient under sedation should be present for all pediatric dental procedures, according to a joint statement from the American Society of Anesthesiologists, Society for Pediatric Anesthesia, American Society of Dentist Anesthesiologists and Society for Pediatric Sedation.
