This study looked at 39 ICU patients with low blood volume to see if changes in pulse pressure (a measure from blood pressure readings) could predict whether they would benefit from extra fluids. Doctors used a leg-raising maneuver and echocardiography to check fluid response. Th…

This study tested whether giving patients extra fluids based on their weight before surgery could prevent low blood pressure after anesthesia. 110 women having gynecological pelvic surgery were randomly assigned to receive either preemptive fluids or standard fasting. The results…

This study looked at 30 people having brain surgery to see if tilting their body up or down changes a device that measures pain (called ANI) while they are asleep. The goal was to understand if the device is still accurate when blood flow shifts. Results will help doctors better …

This study looked at whether ultrasound measurements of the heart and blood vessels can predict which children on breathing machines will benefit from extra fluids. Only 4 children participated, so the findings are very limited. The goal was to find a better way to avoid giving u…

This study looked at how two different amounts of IV fluids given during lung surgery affect the health of blood vessel linings. 41 adults having lung surgery received either a low or high rate of fluid. Researchers measured markers of blood vessel damage before, during, and afte…

This study looked at whether not eating before surgery (preoperative fasting) causes low blood volume. Researchers used heart ultrasound to measure blood volume changes in 100 patients scheduled for gynecological or abdominal surgery. The goal was to see if fasting leads to a dro…
