引言伤口渗出是常见的全膝关节置换术（TKA）和持续的伤口感染是感染的危险因素，并增加了住院时间和成本。结果59例患者（77%）采用髌旁内侧入路，其中12例患者（10%）采用髌旁内侧入路，其余患者均采用髌旁内侧入路股下肌18例（23%）。34例（44%）患者采用关节周围局部麻醉（0.25%布比卡因与1：1，000，000肾上腺素）。平均止血带时间为83分钟（范围：38-125分钟）。我们发现渗出停止与关节周围局部麻醉（P = 0.003），止血带时间（P = 0.03）和股下入路（P = 0.01）之间存在显著相关性。结论关节周围局部麻醉，股下入路和较短的止血带时间均与全膝关节置换术后伤口渗出减少相关。
INTRODUCTION Wound ooze is common following total knee arthroplasty (TKA) and persistent wound infection is a risk factor for infection, and increased length and cost of hospitalisation.PATIENTS AND METHODS We undertook a prospective study to assess the effect of tourniquet time, peri-articular local anaesthesia and surgical approach on wound oozing after TKA.RESULTS The medial parapatellar approach was used in 59 patients (77%) and subvastus in 18 patients (23%). Peri-articular local anaesthesia (0.25% Bupivacaine with 1:1,000,000 adrenalin) was used in 34 patients (44%). The mean tourniquet time was 83 min (range, 38-125 min). We found a significant association between cessation of oozing and peri-articular local anaesthesia (P = 0.003), length of the tourniquet time (P = 0.03) and the subvastus approach (P = 0.01).CONCLUSIONS Peri-articular local anaesthesia, the subvastus approach and shorter tourniquet time were all associated with less wound oozing after total knee arthroplasty.
