Comparative Study
Comparison of pulmonary arterial thermodilution and arterial pulse contour analysis: evaluation of a new algorithm.
To compare cardiac index (CI) measurement by arterial pulse contour analysis using two different algorithms (CI(PC), CI(PCnew)) with pulmonary arterial thermodilution values (CI(PA)) so as to evaluate the difference between the conventional algorithm, CI(PC), and a new algorithm, CI(PCnew), that accounts for patients' individual aortic compliance. ⋯ Arterial pulse contour analysis measurement of CI using either algorithm correlates well with CI values derived by pulmonary arterial thermodilution. However, the algorithm introduced in this study proved to be a more accurate predictor of values as derived by pulmonary artery catheter.

To investigate whether intraoperative fluid management contributes to postoperative respiratory disturbances in esophagectomy for carcinoma. ⋯ Careful intraoperative fluid administration may decrease postoperative respiratory disturbances.

To estimate the optimal endotracheal tube (ETT) length in orotracheally intubated patients. ⋯ The optimal insertion length of the ETT for orotracheally intubated adult patients with the head placed in a neutral position is correlated with body height. The proposed formula can provide a useful guide to determine the optimal ETT tip position in most of the patients who required orotracheal intubation.
