PurposeThird-generation hydroxyethyl starch (HES) 130/0.4 has a larger dose limitation (up to 50 mL/kg/day) than HES 70/0.5 (up to 1000 mL/day) which has been used in Japan for 40 years. The aim of this study was to survey the current intraoperative blood transfusion and volume therapy and to predict the possible reduction of intraoperative albumin consumption assuming further replacement by HES 130/0.4 using data obtained from a survey by the Japanese Society of Anesthesiologists (JSA), although HES130/0.4 was not launched in Japan during this survey period.MethodsIn a JSA survey conducted at JSA-certified hospitals, 12,856 patients with a certain amount of blood loss were analyzed for 1 month (April, 2012). The patients were divided into two groups-group A included patients aged ≥11 years and group B included patients aged <10 years. The possible lower volume of intraoperative albumin was calculated assuming that HES 130/0.4 was used up to a dose of 50 mL/kg.ResultsBlood loss (total 15,111 L; 15,057 L in group A and 54 L in group B) was treated with allogeneic transfusion (total 7970 L; 7893 L in group A and 77 L in group B) and auto-transfusion (total 1777 L; 1771 L in group A and 6 L in group B) in both groups (n = 11,670 and 119). Albumin (total 1391 L; 1376 L in group A and 15 L in group B), and HES 70/0.5 (total 7645 L; 7638 L in group A and 7 L in group B) were used in both groups (n = 10,850 and 116). Five percent and 4.4 % albumin (total 1189 L; 1180 L in group A and 9 L in group B) could be replaced by HES 130/0.4 if HES 130/0.4 had been used up to a dose of 50 mL/kg.ConclusionBlood loss (15,111 L) was replaced with allogeneic transfusion (53 %), auto-transfusion (12 %), albumin (9 %) and HES 70/0.5 (51 %) during surgery in April 2012. The predicted volume of 5 and 4.4 % albumin saved during this 1-month period if HES 130/0.4 had been used up to a dose of 50 mL/kg was 1189 L (86 % of actual amount used).
