Transesophageal echocardiography (TEE) is a semi-invasive monitoring technique increasingly used in cardiac surgery and in major noncardiac surgery for patients with known or supposed cardiac or coronary problems. During lung transplantation (LTx), the close interrelation between heart and lung function makes TEE an invaluable tool for instantly monitoring the physiopathological situation in the subsequent steps of the intervention. In patients scheduled for LTx, induction of anesthesia could be a dangerous moment with the possibility of cardiogenic shock if pulmonary hypertension (PH) exists; pneumatic tamponade is also possible in patients with emphysema caused by alpha(1)-antitrypsin deficiency, with subsequent cardiac insufficiency. ⋯ Lung reperfusion brings with it the possibility of coronary gaseous embolism, easily detected with TEE. After LTx, TEE can be used to detect strictures, thrombi, or permeability of pulmonary venous anastomoses. To summarize, intraoperative TEE during LTx contributes to the immediate recognition of critical events and allows for rapid therapeutic interventions.

The aim of this study was to create a model that forecasted the stay in the intensive care unit in post-liver transplantation. ⋯ The most significant parameters were total bilirubin, serum creatinine, and serum sodium. The proposal model significantly correlated with the variable "intensive care unit stay." Such data are particularly important since increased intensive care unit stay correlates with a significant reduction in 1-year survival rate.
