Randomized Controlled Trial
Low- vs. high-pressure suction drainage after total knee arthroplasty: a double-blind randomized controlled trial.
The aim of this study was to assess the efficacy of continuous low-pressure suction drainage compared with closed high-pressure suction following total knee arthroplasty. ⋯ Continuous low-pressure suction of 50 mmHg is not more effective than the higher aspiration pressure system to diminish the blood loss in total knee arthroplasty. The results do not support any change in current nursing practice relating to the use of this drain system.
