Obstruction of a non-resterilized reinforced endotracheal tube during craniotomy under general anesthesia.

Many cases of reinforced endotracheal tube (ETT) obstruction were reported in the literature. In most of these cases, the obstruction was related to the use of a resterilized tube with or without the use of nitrous oxide (N2O). Resterilization and autoclaving of the tube may result in dissection or formation of a bleb between the two layers of the tube that may expand after the use of N2O. We describe a case of acute non-resterilized reinforced ETT obstruction, by bleb formation, during occipital craniotomy under general anesthesia.

Allergic myocardial ischemia causing reversible hemodynamic collapse during gastroscopy.

This case report details the development of an acute heart dysfunction during gastroscopy under sedation in a patient with normal coronary arteries. The early diagnosis by echocardiography and aggressive management allowed us to prevent a serious and fatal outcome. We spot on the diagnosis of allergic cardiogenic shock based on our clinical and laboratory finding.
