Temporary Clamping of Drains Combined With Tranexamic Acid Reduce Blood Loss After TKA: A Prospective RCT
November 4, 2011 updated by: Keerati Charoencholvanich, Mahidol University
Temporary Clamping of Drains Combined With Tranexamic Acid Reduce Blood Loss After Total Knee Arthroplasty: A Prospective Randomized Controlled Trial.
Total knee arthroplasty (TKA) may be associated with significant blood loss, and transfusion carries substantial risk of immunologic reaction and disease transmission.
Several methods reportedly reduce postoperative blood loss and avoid homologous blood transfusion with traditional TKA approaches.
Drain clamping was one of the widely used method and tranexamic acid administration was the recently adjuvant method to reduce blood loss in TKA.
However, there were several regimens in either drain clamping or tranexamic acid administration reported in previous studies.
Our objective was to compare the efficacy of our drain clamping protocol and/or tranexamic acid regimen for reducing blood loss and transfusion in TKA.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Group A
No clamp and placebo
|
The drain was not clamped.
The patient received placebo (saline 10 minutes before surgery and three hours post-operative, and then an oral form of placebo 2X3 capsules for five days).
|
Experimental: Group B
Tranexamic acid
|
the drain was not clamped and the patient received tranexamic acid 10mg/kg intravenous 10 minutes before inflating the tourniquet and 10mg/kg intravenous three hours post-operative, and then tranexamic acid 250mg/capsule 2X3 orally for five days.
|
Experimental: Group C
Drain clamping
|
the drain was clamped for three hours, released for three hours, then clamped for another three hours, and then released free for 48 hours.
The patient received placebo (saline 10 minutes before surgery and three hours post-operative, and then an oral form of placebo 2X3 capsules for five days).
|
Experimental: Group D
Drain clamping and tranexamic acid
|
the drain was clamped for three hours, released for three hours, then clamped for another three hours, and then released free for 48 hours.
the patient received tranexamic acid 10mg/kg intravenous 10 minutes before inflating the tourniquet and 10mg/kg intravenous three hours post-operative, and then tranexamic acid 250mg/capsule 2X3 orally for five days.
