ReviewA review of aprotinin in orthotopic liver transplantation: can its harmful effects offset its beneficial effects?
Blood transfusion can adversely affect patient outcome and graft survival in orthotopic liver transplantation (OLT). With this respect, prophylactic aprotinin administration decreases blood loss, transfusion requirements, and the hemodynamic changes associated with graft reperfusion in patients undergoing OLT. ⋯ Whether the inhibition of fibrinolysis associated with aprotinin therapy will expose some patients to untoward thrombosis is questionable; (b) aprotinin does not appear to alter postoperative outcome in patients undergoing OLT; (c) aprotinin decreases blood transfusion requirements only when surgery is associated with significant blood loss. However, at the present time, median transfusion requirements of 2 to 5 red blood cell units are required in OLT.

Cannot intubate-cannot ventilate and difficult intubation strategies: results of a Canadian national survey.
The purpose of this study was to determine the preferences of Canadian anesthesiologists in difficult intubation and cannot intubate-cannot ventilate (CICV) situations. Using a mailed survey, we asked anesthesiologists their preferences for and comfort level in using (a) alternative airway devices in a difficult intubation scenario and (b) infraglottic airway in a CICV scenario. Chi-square analysis and Student's t-test were used for categorical and continuous variables. ⋯ In conclusion, in a difficult intubation scenario, the lighted stylet has emerged as the preferred alternative airway device. In a CICV scenario, respondents preferred cricothyroidotomy by IV catheter, followed by percutaneous cricothyroidotomy and tracheostomy by surgeon. Practice on mannequins was associated with improved comfort in using infraglottic airways in patients.
