我们的目的是评估使用比色法的术中失血量的重量估计的准确性。在2个月期间，从普通妇科病例中随机选择40个剖腹手术海绵。手术室工作人员通过称量海绵来评估每个海绵上所含的血液。然后将海绵中所含的血红蛋白转化为碱性血红素，并在Beckman分光光度计中在465 nm处进行测量。使用患者的术前血红蛋白测量值来确定海绵中存在的血量。对重量法和比色法进行了统计学比较。我们发现重量法估计的失血量与比色法测量的实际失血量之间无统计学显著相关性（P = 0.074）。评估术中失血量的重量法既不精确也不准确。
Our objective was to assess the accuracy of gravimetric estimation of intraoperative blood loss using the colorimetric method. Forty laparotomy sponges were selected randomly from general gynecology cases during a 2 month period. The blood contained on each sponge had been assessed by the OR staff by weighing the sponges. The hemoglobin contained in the sponges was then converted to alkali hematin and measured in a Beckman spectrophotometer at 465 nm. Using the patient's preoperative hemoglobin measurement, the amount of blood present in the sponges was determined. The gravimetric and colorimetric measurements were compared statistically. We found no statistically significant correlation between the amount of blood loss estimated by the gravimetric method and the actual blood loss as measured by the colorimetric method (P = 0.074). The gravimetric method of assessing intraoperative blood loss is neither precise nor accurate.
