[An Analysis of Autologous Blood Transfusion in Major Orthopedic Surgery : Our Experience with 2,262 Patients.].

Background: Allogenic blood transfusion accompa- nies the risks of infection, allergic reaction, and immune suppression. We analyzed the patients having autolo- gous blood transfusion in major orthopedic surgery in our hospital.

Methods: We analyzed 2,262 patients scheduled for autologous transfusion for the last 22 years (from Sep- tember 1991 to September 2013) retrospectively.

[Analysis of the Factors in Successful Helmet Non-invasive Positive Pressure Ventilation].

Background: Non-invasive positive pressure ventilation (NPPV) reduces the incidences of ventilator-associated pneumonia, the duration of ICU stay and the mortality rate compared with conventional respiratory management of the patients with acute respiratory failure (ARF). Recently, helmet NPPV equipment became available. Because of the high tolerability, the helmet seems to be the best NPPV interface when prolonged and continuous assistance is needed.
