This study looks at whether giving the painkiller nalbuphine at different times during knee replacement surgery can better control pain and keep the heart stable in patients aged 65 and older. About 162 participants will receive the same total dose of nalbuphine, but at different…

This study tests whether using virtual reality (VR) goggles or a sedative drug called dexmedetomidine is better at reducing anxiety and stress in women having a planned cesarean section. About 52 mothers will be randomly assigned to one of the two methods. The goal is to find a s…

This study looks at how blood flow in the gut changes after feeding in critically ill ICU patients. Doctors will use a bedside ultrasound to measure these changes and see if they can predict gut injury. The goal is to make feeding safer and reduce complications. About 80 adults w…

This study looks at two methods of releasing a tourniquet after upper arm surgery in people with high blood pressure. The goal is to see which method causes less of a sudden drop in blood pressure. Researchers will monitor blood pressure and other health markers in 68 adults.

This study compares two operating-room monitors—stroke volume variation (SVV) and the Pleth Variability Index (PVI)—to see which more accurately predicts whether giving fluids will help the heart pump better during laparoscopic major abdominal surgery. About 300 adults having ele…

This study aims to find the right dose of remifentanil (a strong painkiller) to prevent sudden changes in heart rate and blood pressure when a breathing tube is placed during anesthesia. About 99 adults having planned surgery will take part. Researchers will compare two drug comb…

This study tracks 242 pregnant women to measure how the heart and blood vessels adapt during pregnancy and after childbirth. Researchers use non-invasive tests like heart rate monitoring and blood pressure checks to understand normal changes and spot early signs of complications.…
