CEREBRAL OXYGENATION

This study looks at whether giving surfactant (a lung treatment) over 1 minute or 5 minutes helps very premature babies (under 28 weeks) stay more stable. The goal is to see which speed leads to better oxygen levels in the blood and brain. 76 babies will take part, and the result…

This study looks at two methods of helping elderly patients breathe during the start of anesthesia: manual ventilation by a doctor and mechanical ventilation using a machine. Researchers will measure oxygen levels in the brain and body to see which method works better. The goal i…

This observational study is looking at whether the brain's ability to use oxygen during surgery is linked to postoperative delirium in adults aged 65 and older. Researchers will use a non-invasive forehead sensor to measure brain oxygen levels during routine laparoscopic surgery …

This study observes 80 adults with and without diabetes to see how long-term blood sugar control (measured by HbA1c) affects brain oxygen levels during urologic surgery. Researchers use a special light device (NIRS) to measure brain oxygen and track recovery after surgery. The go…

This study watches 40 adults having shoulder surgery while sitting up (beach chair position). Researchers want to see if a special headband that measures brain oxygen levels gives extra safety information beyond standard heart and blood pressure monitors. The goal is to learn how…

This study compares two common anesthesia methods—inhaled gases (sevoflurane or desflurane) versus intravenous propofol—in 84 adults having brain tumor surgery. Researchers will measure brain oxygen levels, swelling, and thinking skills after surgery to see which approach better …
