After total knee arthroplasty (TKA) the technique of wound management is not standardised. In this prospective study the efficacy of autologous blood reinfusion from the wound was investigated. One hundred patients (100 TKAs) were enrolled in this sequential cohort study. In one-half of the operations, a reinfusion system with suction and in the other half one wound drain without suction were used. Blood loss, transfusion requirements, range of motion, Insall scores and the incidence of complications were studied. The use of a reinfusion system did not decrease the homologous transfusion requirements. The blood loss in the group with a suction drainage system was significantly higher. Our experiences since May 2002 with one drain without suction in 787 consecutive TKAs confirm all findings of the current study.
全膝关节置换术(TKA)后,伤口处理技术尚未标准化。在这项前瞻性研究中,对伤口自体血回输的疗效进行了调查。100例患者(100次TKA手术)纳入了这项序贯队列研究。在一半的手术中,使用了带有吸引装置的回输系统,另一半则使用了无吸引装置的伤口引流管。研究了失血量、输血需求、活动范围、Insall评分以及并发症的发生率。使用回输系统并未降低异体输血需求。使用吸引引流系统组的失血量显著更高。我们自2002年5月以来在787例连续TKA手术中使用无吸引装置的单根引流管的经验证实了本研究的所有结果。
