目的：探究输血科关于老年肿瘤患者的限制性输血的应用效果。方法：将2019.01～2020.06本院输血科接受输血申请的120例老年肿瘤患者纳入研究，按抛硬币法分为对照组60例，实施开放性输血；治疗组60例，实施限制性输血，观察治疗效果。结果：输血后，治疗组血红蛋白（Hb）含量高于输血前，差异显著（P＜0.05），但与对照组对比无显著差异（P＞0.05）；治疗组输血总量少于对照组，差异显著（P＜0.05）；治疗组不良反应发生率为0.00%，低于对照组10.00%，差异显著（P＜0.05）。结论：输血科中应用限制性输血能够取得良好的治疗效果，同时减少输血总量及不良反应的发生，有效节约血资源，应用于老年肿瘤患者中安全可靠。“,”Objective: To discuss the applied effects of restrictive transfusion in elderly cancer patients. Methods: 120 elderly cancer patients of receiving the blood transfusion from January 2019 to June 2020 in our blood transfusion department were investigated and assigned to control group (60 cases, open transfusion) and treatment group (60 cases, restrictive transfusion). Clinical effects were probed. Results: Hemoglobin (Hb) contents in the treatment group after transfusion were significantly higher than before (P＜0.05); Hb contents between treatment group and control group were not significantly different (P＞0.05); the overall blood transfusion volume in the treatment group was significantly smaller than control group (P＜0.05); the adverse transfusion reaction rate in the treatment group (0.00%) was significantly lower than control group (10.00%)(P＜0.05). Conclusion: The restrictive transfusion can reduce the overall blood transfusion volume and adverse reactions, and save the medical resources; it is proven to be safe and reliable for elderly cancer patients.
