Case ReportsFatal air embolism during cardiopulmonary bypass: analysis of an incident and prevention measures.
Air embolism is a life-threatening complication during cardiopulmonary bypass. We present a case of a patient who suffered an air embolism during coronary bypass surgery, despite standard safety features and procedures. The patient died 3 days after surgery due to massive cerebral oedema. This case report gives a reconstruction of the event and the countermeasures undertaken to minimize the risk of recurrence.

Recursive and non-linear logistic regression: moving on from the original EuroSCORE and EuroSCORE II methodologies.
EuroSCORE II, despite improving on the original EuroSCORE system, has not solved all the calibration and predictability issues. Recursive, non-linear and mixed recursive and non-linear regression analysis were assessed with regard to sensitivity, specificity and predictability of the original EuroSCORE and EuroSCORE II systems. ⋯ The original EuroSCORE and the EuroSCORE II risk models do not have adequate ROC and Hosmer-Lemeshow statistics to allow accurate assessment of cardiac surgeons in the modern era. A mixed recursive and non-linear regression model utilizing the EuroSCORE II risk model improves both the ROC and Hosmer-Lemeshow statistics.
