U.S., Sept. 17 -- ClinicalTrials.gov registry received information related to the study (NCT07823569) titled 'Effect of Prone Position on Continuous Noninvasive Hemoglobin Measurement' on Sept. 11.
Brief Summary: This prospective observational study aims to evaluate whether the prone position affects the agreement between noninvasive hemoglobin (SpHb) measurements and laboratory hemoglobin values in patients undergoing lumbar stabilization surgery under general anesthesia.
SpHb provides continuous, noninvasive monitoring of hemoglobin using multi-wavelength pulse CO-oximetry. However, its accuracy may be affected by changes in peripheral perfusion, hemodynamic status, and patient position. The prone position used during spine surgery may ...
