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.

Comparative Study
Postoperative nausea and vomiting after craniotomy for tumor surgery: a comparison between awake craniotomy and general anesthesia.
To assess the frequency of postoperative nausea and vomiting (PONV) in patients following an awake craniotomy compared to general anesthesia for tumor surgery. ⋯ The frequency of PONV during the initial recovery phase was less in patients having an awake craniotomy for tumor surgery than in patients having a similar procedure with general anesthesia.

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.

Biography Historical Article
Gaston Labat, John Lundy, Emery Rovenstine, and the Mayo Clinic: the spread of regional anesthesia in America between the World Wars.
The spread of regional anesthesia in America was greatly facilitated by the work of Gaston Labat. Recruited to work at the Mayo Clinic, Dr. ⋯ John Lundy continued Labat's work at the Mayo Clinic when Labat left for Bellevue Hospital in New York. There, while teaching, Labat further developed and refined his techniques for delivering regional anesthesia.
