Does temporary clamping of drains following knee arthroplasty reduce blood loss ? A randomised controlled trial . In a randomised , blinded study 76 patients undergoing primary total knee arthroplasty were assigned to either immediate drain opening ( n = 45 ) or drains opened at 2 h ( n = 31 ) . No significant differences were found between the groups for the volume of drained blood , transfusion requirements , knee motion or wound status . The authors conclude that the practice of clamping drains has no benefit in routine knee arthroplasty . However , when faced with immediate brisk blood loss , the results suggest that drains can be clamped without any excess morbidity .
