Comparative StudyComparative fading responses induced by mivacurium, cisatracurium, and d-tubocurarine in the evoked muscular compound action potentials of the cat.
It has been suggested that the different degrees of fade induced by nondepolarizing neuromuscular blocking agents in repetitive muscular contractions may be due to the varying affinities or binding kinetics of presynaptic nicotinic receptors. We compared the degree of fade induced by mivacurium, cisatracurium, and d-tubocurarine in the cat muscular compound action potential (mCAP). ⋯ Our results suggest that mivacurium shows a lesser degree of fade during partial neuromuscular block than cisatracurium and d-tubocurarine.

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.

Comparative Study Clinical TrialComparison of hemodynamic and anesthetic effects of hyperbaric bupivacaine and tetracaine in spinal anesthesia.
To compare the anesthetic and hemodynamic effects and the predictive factor of anesthesia level of commonly used preparations of hyperbaric bupivacaine and tetracaine in spinal anesthesia. ⋯ In spinal anesthesia, hyperbaric tetracaine in 10% glucose induced a faster and higher spread of anesthesia than hyperbaric bupivacaine in 7.27% glucose without any differences in hemodynamics.

Survey of patients whose lungs could not be ventilated and whose trachea could not be intubated in university hospitals in Japan.
We conducted a survey to clarify the actual circumstances in which the lungs could not be ventilated and the trachea could not be intubated (CVCI). ⋯ This survey demonstrates that CVCI can occur in any situation in which the airway is not established. Furthermore, effective treatments may be different depending on the situation, and delayed recognition of tracheal tube misplacement may lead to a serious outcome.
