Intrathoracic blood volume index measured by thermodilution for preload monitoring after cardiac surgery.
To investigate the accuracy of measurement of intrathoracic blood volume index by single thermodilution (ITBVI*) and its sensitivity to detect changes in preload after cardiac surgery compared with conventional transpulmonary arterial dye dilution ITBVI and with conventional monitoring (central venous pressure [CVP] and left ventricular end-diastolic area index [EDAI] by transesophageal echocardiography). ⋯ In patients undergoing cardiac surgery, determination of ITBVI* revealed close agreement with measurements derived by ITBVI. Enhancement in cardiac preload was adequately detected by ITBVI*.

A cadaver study to measure the adult glottis and subglottis: defining a problem associated with the use of double-lumen tubes.
To test the hypothesis that the adult cricoid diameter is the same or less than that of the glottis. ⋯ The ruling diameter of the adult larynx is not the glottis but the cricoid ring. Its correlation with height is extremely poor, and it averages 3.5 mm less in females than males of the same height. These findings are important for thoracic anesthesiologists.
