122 uncemented total knee replacements were randomised to either have high pressure drainage or low pressure drainage (Bellovac)
The total blood loss was significantly lower in the low vacuum group, compared to the patients that had a high vacuum drain (mean blood loss 1364 ml vs 1695 ml, p<0,00062).
According to the authors, “the blood loss following knee replacement operations is substantial and can also be affected by the vacuum pressure in suction drains”.“High suction pressure drains are not necessary, and may be detrimental when used following uncemented total knee replacement”
