The current study was designed to determine the relation between preoperative cerebral oxygen saturation (Sco2), variables of cardiopulmonary function, mortality, and morbidity in a heterogeneous cohort of cardiac surgery patients. ⋯ Preoperative Sco2 levels are reflective of the severity of cardiopulmonary dysfunction, associated with short- and long-term mortality and morbidity, and may add to preoperative risk stratification in patients undergoing cardiac surgery.

Neuromuscular blocking agents (NMBA) are responsible for most immediate hypersensitivity reactions during anesthesia, as a result of the presence of a quaternary ammonium ion. The aim of this study was to evaluate the diagnostic performance of a commercial immunoglobulin E (IgE) test (quaternary ammonium morphine [QAM]) for diagnosing sensitivity to NMBA. ⋯ Sensitivity of the QAM test (84.2%), together with its simplicity and suitability for routine laboratory use, makes it a valuable tool, in conjunction with skin tests, for diagnosing NMBA sensitivity in patients who react after NMBA injection. The QAM test is of particular interest when skin tests are not available or not reliable or give results poorly compatible with mediator release or clinical features.
