Title: Effect of Time of Temporarily-closed Wound Drainage Tube on Drainage Volume of Patients Early after Total Knee Replacement Surgery
Abstract: Objective To observe the effect of temporarily-closed wound drainage tube and time of clipping pipe on drainage volume early after knee replacement surgery.Methods 64 patients with total knee replacement surgery were randomly divided into observation group 1,observation group 2 and control group.The drainage tube in observation group 1 was closed 2 hours after the surgery and 4 hours after the surgery in observation group 2,while the drainage tube was kept open in control group.The volume of wound drainage 48 h after the surgery was recorded and analyzed.Results Average volume of wound drainage in observation groups 48 hour after surgery was significantly less than that of control group.Average volume of wound drainage in observation group 2 was noticeably less than that in observation group 1.No significant differences existed in scores of knee joint function among three groups.Conclusion During total knee arthroplasty,closing drainage tube early after the surgery can decrease the volume of bleeding.The effect of keeping tube close for 4 hours is better than that for 2 hours and no adverse effects on healing of incision and knee functional recovery exist.
