Pharmacokinetic modelling during long-term anesthesia: minimizing the gap.

Summary: When people need surgery that takes many hours, or if they are very sick and need a breathing machine, doctors put them into a deep sleep. But there is a hidden danger. If a patient is overweight, the sleep medicine can get trapped in their body fat. This means the drug stays in their body too long, which can be risky. Scientists have created a new computer model to fix this. It measures a person's body size and changes how the medicine is given. Using a smart computer program, doctors can give just the right amount of medicine. This keeps the patient safely asleep while using less drug overall, helping them wake up faster and safer!
