We investigated the contribution of swab washing to the efficiency of red cell recovery by intraoperative cell salvage (ICS) in 10 patients undergoing elective aortic aneurysm repair.
Volumes and haemoglobin (Hb) concentrations were recorded in the blood recovered by direct suction and from washed swabs, both before and after processing with a Haemonetics Cell Saver 5.
The mean +/- standard deviation (SD) estimated blood loss was 991 +/- 403 ml, resulting in a mean +/- SD salvaged RBC volume of 380 +/- 124 ml. The median [interquartile (IQR) range] Hb collected from suction was 84.9 (61.8-131.4) g, of which 50.1 (45-71.5) g was returned to the patient after processing, a median yield of 68 (49-77)%. The swab wash produced a median (IQR) Hb of 39.4 (28.4-64.9) g, of which 26.2 (16.8-31) g was reinfused, a 67 (33-98)% yield. Swab wash thus contributed with a median (IQR) of 31 (24-39)% of the total RBC recovery.
Washing swabs improves the efficiency of red cell recovery by ICS.
我们研究了拭子冲洗对10例行择期主动脉瘤修复术患者术中细胞回收（ICS）红细胞回收效率的影响。
使用Haemonetics Cell Saver 5处理前后，记录直接抽吸回收的血液以及冲洗拭子回收的血液的体积和血红蛋白（Hb）浓度。
估计平均±标准差（SD）失血量为991±403 ml，平均±SD回收的红细胞体积为380±124 ml。抽吸收集的Hb中位数[四分位间距（IQR）范围]为84.9（61.8 - 131.4）g，处理后50.1（45 - 71.5）g回输给患者，中位数回收率为68（49 - 77）%。拭子冲洗产生的Hb中位数（IQR）为39.4（28.4 - 64.9）g，其中26.2（16.8 - 31）g被回输，回收率为67（33 - 98）%。因此，拭子冲洗对红细胞总回收量的贡献中位数（IQR）为31（24 - 39）%。
冲洗拭子可提高ICS红细胞回收效率。
