Ventilator-Associated Pneumonia: Comparing Cadaveric Liver Transplant and Non-Transplant Surgical Patients
Ventilator-associated pneumonia is a frequent complication in intensive care surgical patients, particularly those with high severity scores on admission. We studied the incidence and clinical outcome of ventilator-associated pneumonia among patients undergoing major general surgery procedures and those undergoing cadaveric liver transplantation in our hospital. Patients with the intensive care unit stay longer than four days having undergone surgery or transplantation and mechanically ventilated for more than 48 hours were included in the study. ⋯ However, the main difference was the mean severity score on admission (Simplified Acute Physiology Score II) which was higher among non-transplant patients (42±16 vs. 31±9; p=0.03). Gram-negative bacteria were the leading causative agents (82.03%) and were multidrug-resistant. In the intensive care surgical population, transplantation per se does not seem to increase patient risk for either ventilator-associated pneumonia acquisition or worse outcomes.

Randomized Controlled TrialInfluence of Fondaparinux Versus Nadroparin Calcium Thromboprophylaxis on Clinical Parameters Following Total Knee Arthroplasty
Fondaparinux has been shown to be as effective as low molecular weight heparin in orthopedic surgery, with no cases of heparin induced thrombocytopenia proven until today. The main goal of this prospective randomized controlled trial was to define whether thromboprophylaxis in patients with primary osteoarthritis of the knee undergoing total knee arthroplasty (TKA) influences clinical parameters in the same manner in patients receiving fondaparinux as in those receiving nadroparin during the first 7 postoperative days. Sixty patients with primary knee osteoarthritis underwent unilateral TKA performed by the same surgeon and were randomized into two groups of 30 patients receiving either fondaparinux or nadroparin thromboprophylaxis. ⋯ No differences were found between the groups in the mean duration of surgery, perioperative blood loss, and most of laboratory results. The level of urea was significantly lower in the nadroparin group on the first and second postoperative day. No cases of heparin induced thrombocytopenia, deep vein thrombosis or pulmonary embolism were noted during the study. Study results showed both fondaparinux and nadroparin to have the same influence on clinical parameters during the first 7 postoperative days in patients undergoing TKA.
