<p>A lower tourniquet inflation pressure of 120 mm Hg above systolic blood pressure (SBP) is effective during total knee arthroplasty (TKA), according to this study. The researchers sought to determine if a lower pressure is as effective as conventional tourniquet pressure (SBP + 150 mmHg) in decreasing blood loss and providing a bloodless surgical field. To conduct this study, researchers arbitrarily assigned 160 knees in 124 patients undergoing TKA to either conventional (n=80) or lower inflation pressure groups (n=80). After assessing efficacy variables, and safety outcome variables, results showed that a comparable bloodless surgical field was provided by both groups. Moreover, the two groups did not differ in safety outcomes.<p>Read more: <a href="https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/s12891-019-2636-7">https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/s12891-019-2636-7</a></p></p>
