Prevention of iodinated contrast-induced nephropathy.

Objective: To lessen the occurrence of contrast-induced nephropathy (CIN), the preventive measures of CIN were reviewed.

Data Sources: The data used in this review were from PubMed with relevant English articles and from Chinese Knowledge Information (CNKI) published from 1989 to 2009. The search terms were "contrast medium", "contrast-induced nephropathy" and "prevention".

Balloon occlusion of the right main bronchus in an ovine model provides sufficient time for emergent interventions in massive pulmonary embolism.

Purpose: Massive pulmonary embolism (PE) causes hemodynamic compromise and is associated with a high rate of mortality. We sought to create a model of massive PE and to determine whether occlusion of the right main bronchus could mitigate the physiological effects of massive PE in this model.

Materials And Methods: We used 27 female sheep to generate a model of massive PE by either autologous blood clot injection (n=18) or detachable balloon release (n=9) into the right main pulmonary artery.

[Comparison of the massive pulmonary embolism of the animal model stabled by different methods].

Objective: To contrast the massive pulmonary embolism of the animal model had been stabled by inserting the animal's own blood clots or through use of detachable latex balloons.

Methods: Eighteen healthy sheep were separated as three groups with random. We established the animal lung, PE model by inserting the animal's own blood clots at right lung artery in 6 sheep, and 6 sheep were through used of detachable latex balloons to substitute the blood clots.
