Randomized Controlled Trial Clinical TrialHemodynamic and bispectral index responses to tracheal intubation during isoflurane or sevoflurane anesthesia.
The effects of volatile anesthetics on change in the bispectral index (BIS) due to tracheal intubation are unclear. We investigated hemodynamic and BIS responses to intubation during isoflurane or sevoflurane anesthesia. ⋯ Anesthesia with 2 MAC of isoflurane and sevoflurane was effective to suppress the change in BIS due to intubation but was not sufficient to prevent changes in hemodynamic responses.

Neuromuscular disease covers a wide range of conditions, with anesthesia management being required either for problems relevant to the disorder or for comorbid conditions. The diseases often have specific problems that can usually be predicted from their pathophysiology. The anesthesiologist must ensure a thorough preoperative assessment, appropriate choice of anesthetic technique and neuromuscular blocking drugs, and careful monitoring of both hemodynamic parameters and the degree of neuromuscular blockade. With these considerations, the patient with neuromuscular disease, although challenging, can be given anesthetic care in a safe fashion.

Newly developed T-wave inversion with cardiac wall-motion abnormality predominantly occurs in middle-aged or elderly women after noncardiac surgery.
The study was done to determine the characteristics and prevalence of myocardial ischemia with inverted T waves after noncardiac surgery. ⋯ Newly developed giant negative T waves with QT prolongation in the ECG may indicate myocardial stunning, but do not in themselves imply a poor prognosis. The marked preponderance of middle-aged and elderly women with this type of myocardial ischemia remains to be explained.
