Shortening fasting before planned surgery

This study compares two ways of eating before planned (elective) orthopedic surgery: intermittent fasting versus carbohydrate drinks. It aims to see which approach is safer and works better around the time of surgery.

This trial looks at whether the length of time you fast (not eating or drinking) before and after surgery affects your risk of becoming confused or disoriented (called delirium). It may help you avoid confusion after surgery by finding a safer fasting routine.

This study looks at how fasting before anesthesia affects recovery for people having procedures. Researchers want to understand what happens to patients when they have nothing to eat or drink before anesthesia.

This trial tests whether not eating before a procedure (called preoperative fasting) is better than fasting in ICU patients who are already receiving tube feedings. It aims to find out if skipping the fast can help you without causing extra risks.

This trial tests whether allowing patients to drink clear fluids (like water or juice) up until surgery starts is safe, instead of fasting for hours. It may help you feel more comfortable before your operation.

This study looks at whether the length of time you fast before surgery can affect your blood pressure after you are put to sleep. The goal is to help doctors manage blood pressure better during operations.
