Summary

This trial tests a new device called ResQ that listens to heart and lung sounds through a soft probe in the esophagus to predict if a patient needs more fluids during surgery. Researchers will compare its accuracy to the standard method using an arterial line. The study involves 122 adults undergoing major abdominal or pelvic surgery under general anesthesia.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: ResQ device (acoustic variability index monitor)
What this could lead to: If successful, this could provide a less invasive way to guide fluid management during surgery, potentially reducing complications.
What could go wrong: This is a small, early-stage trial with only 122 participants, so results may not apply to all patients. The device may not be as accurate as standard methods.
