改进针头过滤法在骨髓采集术中的应用与效果评价

Effects of modified needle filtration on bone marrow collection

目的评价改进针头过滤法在骨髓采集术中的应用效果。方法在原来针头过滤法基础上进行改进升级,随机选取改进前针头过滤法骨髓采集供者80例为常规组,改进后针头过滤法骨髓采集供者80例为改进组,比较两组麻醉时间、采集骨髓时间、应用20ml注射器个数和护理人力数量。结果改进前针头过滤法麻醉时间为(112.30±23.87)min,改进后针头过滤法麻醉时间为(100.50±25.68)min,两组比较差异有统计学意义(t=3.027,P<0.01)。改进前针头过滤法采集骨髓时间为52.00(41.25,60.75)min,改进后针头过滤法采集骨髓时间为39.00(31.25,53.00)min,两组比较差异有统计学意义(U=-3.879,P<0.01)。改进前针头过滤法使用20ml注射器个数为121(103,145)个,改进后针头过滤法使用20ml注射器个数为80(50,100)个,两组比较差异有统计学意义(U=-7.101,P<0.01)。改进前需要2名护士配合,改进后只需要1名护士即可完成骨髓过滤工作。结论改进针头过滤法在骨髓采集术中可缩短麻醉时间,缩短采集骨髓时间,节省无菌物料,节省护士人数,减少骨髓血浪费,减少针刺伤。

Objective To evaluate the effects of the modified needle filtration on bone marrow collection. Methods The original needle filtration was modified and upgraded. Totally 80 bone marrow donors whose bone marrow was collected using the original needle filtration were randomly selected and divided into the control group, while another 80 bone marrow donors whose bone marrow was collected using the modified needle filtration were randomly selected and divided into the modified group. Anesthesia time, time of bone marrow collection, number of 20 ml injectors used and number of nursing staff were compared between the two groups. Results The anesthesia time of the control group was (112.30±23.87) min, while that of the modified group was (100.50±25.68) min (t=3.027, P<0.01). The time of bone marrow collection of the control group was 52.00 (41.25, 60.75) min, whereas that of the modified group was 39.00(31.25, 53.00) min (U=-3.879, P<0.01). The number of 20 ml injectors used in the control group was 121(103, 145), while that in the modified group was 80(50, 100) (U=-7.101, P<0.01). Two nurses were required in the control group, whereas only 1 nurse was needed for bone marrow collection in the modified group. Conclusions The modified needle filtration, when used in bone marrow collection, can shorten the anesthesia time and the time of bone marrow collection, save sterile materials and nursing staff, reduce the wastage of bone marrow blood, and lessen pricking wound.
