两种引流方式在单侧膝关节置换术后的前瞻性临床对比研究.

Objective: The aim of this study was to evaluate the clinical effects in patients who had undergone primary total knee arthroplasty(TKA) with 2 different closed negative pressure drainage(not clip pipe; clip to remain open after 6 hours). Methods: A total of 52 patients(52 knees) underwent primary TKA in our hospital from 2015.06 to 2017.06 was conducted. They were randomly divided into two groups(don’t clip pipe group, clip pipe 6 h). Comparing three groups of patients with postoperative total flow rate and amount of allogeneic blood transfusion, total blood loss and hidden blood loss, postoperative week diameter growth of leg, incision infection rate,incidence of thrombosis and the function of knee joint after December(HSS score) evaluate the situation. Results: There were no significant difference in the baseline characteristics including age, gender, height, weight and time of operation between the two groups(P>0.05). However, total blood loss, hidden blood loss, blood transfusion in study group were higher than that in control group(P<0.05).Multiple comparison between groups of patients, postoperative 1 d, 3 d weeks diameter growth of leg, postoperative incidence of thrombosis, incision infection rate and postoperative HSS score 12 months were no significant statistical difference(P>0.05). Conclusion: Early continuous negative pressure drainage after clip pipe(6 h) can significantly reduce the amount of blood loss and the blood transfusion rate, and do not increase the obvious adverse consequences.
