From: Blood management in fast-track orthopedic surgery: an evidence-based narrative review

Is the incidence of readmissions resulting from VTE and bleeding complications higher with LMWH or with mobile compression plus ASA? In THA, there was no difference in the frequency or readmissions for bleeding complication (wound or systemic) between the treatments. In TKA, patients treated with LMWH had higher readmission rates within 6 weeks after surgery, because of bleeding complications, wound infection, or VTE.
Is the incidence of wound bleeding complications higher with LMWHG or with mobile compression plus ASA? In THA, there was higher wound bleeding complication frequency with LMWH. In TKA, patients treated with LMWH had a higher frequency of wound bleeding complications or infection.
In TKA, is the frequency of systemic bleeding events and complications related to chemoprophylaxis higher with LMWH or with mechanical compression plus ASA? Patients treated with LMWH had higher rates of systemic bleeding or complications.
Is there a difference in symptomatic VTEs between LMWH and mechanical compression plus ASA? There was no difference between the rate of symptomatic VTEs between the groups.
