Altogether 100 cases were studied to compare the subjective estimates of operative blood loss by anaesthetists (six in number) and by surgeons (22 in number). Their estimates were compared with the blood loss measured by a colorimetric method, which was assumed to be the operative blood loss. The results showed that surgeons are less reliable judges of operative blood loss then anaesthetists. When objective measurement of operative blood loss is impracticable the anaesthetist and the surgeon should jointly make a subjective estimation.
共对100例病例进行了研究，以比较麻醉师（共6名）和外科医生（共22名）对术中失血量的主观估计。将他们的估计值与用比色法测量的失血量进行比较，后者被视为术中失血量。结果表明，外科医生对术中失血量的判断不如麻醉师可靠。当无法进行术中失血量的客观测量时，麻醉师和外科医生应共同进行主观估计。
