What Really Happens When You Go Under Anesthesia

What really happens when you go under general anesthesia after 60 or 65? In this video, we explain what happens to your brain and body during anesthesia, from pre-medication and propofol induction to intubation, ventilation, monitoring, emergence, and recovery. You’ll learn about general anesthesia, anesthesia awareness, propofol, older adults, brain health, post-operative delirium, and post-operative cognitive changes. We explain why some seniors may experience temporary confusion, memory problems, difficulty concentrating, or changes in thinking after major surgery, and why age, medications, existing health conditions, and the stress of surgery can all matter. The video also covers regional vs. general anesthesia, medication interactions, fasting before surgery, and important warning signs to watch for after an operation. Most importantly, you’ll get practical questions to ask your anesthesiologist before surgery—including whether regional anesthesia is appropriate, how cognitive risks are addressed, and which medications or supplements need special attention. General anesthesia is considered safe and effective for most patients, including older adults, but individual risks vary. The goal of this video is not to create fear—it is to help you understand anesthesia, prepare for surgery, and have a better conversation with your medical team. 📚 Research & Sources Referenced Anesthesia & Analgesia* — Multicenter U.S. Study on anesthesia awareness FDA — Diprivan (Propofol) Official Prescribing Information ASHRAE Standard 170 / AORN Guidelines — Operating Room Temperature Standards Frontiers in Aging Neuroscience — POCD in the Ageing Population Scientific Reports / Nature* — Prospective Cohort Study on POCD, 2025 American Medical Association — Post-Operative Delirium UT Southwestern Medical Center — Postoperative Delirium in Seniors Journal of Clinical Anesthesia — Regional vs. General Anesthesia 2022 Aging Clinical and Experimental Research — POCD Concept
