Key result
Clinical estimates underestimate perioperative blood loss by ~29% versus laboratory calculations.
Why the study?
Intraoperative blood loss predictions by anesthesiologists and surgeons vary greatly due to different observation angles, and whether these predictions accurately reflect actual blood loss remains debated.
Does clinical estimation by anesthesiologists and surgeons accurately reflect actual perioperative blood loss in major orthopedic surgeries?

Clinical estimates underestimate lab-measured blood loss in major orthopedic surgery, with anesthesiologists more accurate than surgeons; leaves open need for objective quantification in high-volume cases.

Does clinical estimation by anesthesiologists and surgeons accurately reflect actual perioperative blood loss in major orthopedic surgeries?
p-value: p=0.01
Clinical estimation of blood loss during major orthopedic surgery significantly underestimates actual blood loss, particularly when volumes exceed 1000 mL.
Yüzkat et al. (2019) conducted an observational in Major lower extremity bone fractures (n=60). Clinical estimation of blood loss vs. Laboratory calculated blood loss was evaluated on Perioperative mean blood loss volume (p=0.01). Clinical estimates of perioperative blood loss by both the anesthesiologist and surgeon were significantly lower than laboratory-calculated volumes (p=0.01), with an average error rate of 28.72%.
