目的 观察脑膜瘤切除手术患者应用急性等容血液稀释 (ANH)自体输血的临床效果。方法 择期脑膜瘤切除术患者 4 0例 ,随机分为Ⅰ组 (血液稀释组 ,n =2 0 )和Ⅱ组 (对照组 ,n =2 0 ) ,两组患者均采用相同的麻醉方法全麻气管插管 ,Ⅰ组术前进行等容血液稀释。比较两组患者输异体血量和术后血红蛋白变化。结果 Ⅰ组 12例患者未输异体血 ,8例输异体血 2 0 0～ 4 0 0ml,Ⅱ组每例患者均需异体血输入 ,输血量4 0 0～ 80 0ml。结论 急性等容血液稀释可使脑膜瘤切除术患者明显减少异体输血或不输异体血
Objective To observe the clinical effect of acute isovolemic hemodilution (ANH) autotransfusion in patients with meningiomas. Methods Forty patients with meningiomas undergoing elective resection were randomly divided into group Ⅰ (n = 20) and group Ⅱ (n = 20). Patients in both groups received general anesthesia for general anesthesia Intubation, group Ⅰ preoperative isovolumic hemodilution. Transfusion volume and postoperative hemoglobin were compared between the two groups. Results In group Ⅰ, 12 cases had no allogeneic blood and 8 cases had allogeneic blood. The patients in group Ⅱ were required to have allogeneic blood transfusion and blood transfusion between 400 and 80 ml. Conclusions Acute normovolemic hemodilution can significantly reduce allogeneic or non-allogeneic blood transfusion in patients with meningiomas
