California family seeks answers after 3-year-old dies following routine dental procedure

June 19, 2017 | Los Angeles Times

Three-year-old Daleyza Hernandez-Avila recently visited a surgical center in Stockton for what was supposed to be a routine dental procedure. At the center, she underwent general anesthesia for dental crowns, molar repairs and a possible tooth extraction, he said. But on the June 12 visit, her heart stopped about 30 minutes into the procedure. She was later pronounced dead at a hospital.

Why does an anesthetic make us lose consciousness?

June 13, 2017 | American Association for the Advancement of Science

Neuroscientists at Goethe University Frankfurt and the Max Planck Institute for Dynamics and Self-Organization in Göttingen have now discovered that certain areas of the brain generate less information when under anesthesia. The drop in information transfer often measured when the brain is under anesthesia could be a consequence of this reduced local information generation and not - as was so far assumed - a result of disrupted signal transmission between brain areas.

Anesthesiologist: Overlapping Surgeries Led to Safety Issues and Medicare Fraud

June 9, 2017 | Outpatient Surgery Magazine

Anesthesiologist Lisa Wollman, MD, filed a False Claims lawsuit this week against Boston's Massachusetts General Hospital and its parent company, Partners HealthCare System. The suit claims that orthopedic surgeons at the hospital frequently kept patients under anesthesia longer than necessary — sometimes much longer — because they were incentivized by the hospital to do as many procedures as possible. Surgeons routinely scheduled 2, or even 3, overlapping cases, she says.

June 6, 2017 | Outpatient Surgery Magazine

Anesthesia providers often administer ketamine during surgery to help manage post-op pain and prevent delirium, but a new study published in the journal The Lancet suggests the drug does neither in older patients.

Repeated Anesthesia Exposure May Put Children at Risk

June 5, 2017 | Pharmaceutical Processing

Repeated exposure to a common anesthesia drug early in life results in visual recognition memory impairment, which emerges after the first year of life and may persist long-term, according to a study from the Icahn School of Medicine at Mount Sinai and published online in the British Journal of Anaesthesia. Specifically, the study team exposed 10 non-human primate subjects to a common pediatric anesthetic called sevoflurane for four hours, the length of time required for a significant surgical procedure in humans. "Our results confirm that multiple anesthesia exposures alone result in memory impairment in a highly translational animal model."
