U.S., Dec. 4 -- ClinicalTrials.gov registry received information related to the study (NCT07260890) titled 'Paired Comparison of SVV and PVI Accuracy' on Nov. 13.
Brief Summary: This study will compare two operating-room monitors-stroke volume variation (SVV, from the arterial line) and the Pleth Variability Index (PVI, from the pulse oximeter)-to see which one more accurately predicts whether giving a small fluid bolus will improve the heart's pumping during laparoscopic major abdominal surgery. Adults having elective surgery under general anesthesia will receive two small, timed 250-mL crystalloid infusions as part of routine care (one before and one after creation of the pneumoperitoneum). The research team will record SVV and PVI value...
