A 68 year old, ASA physical status 11, hypertensive male patient underwent open reduction, angulated blade plate fixation, and bone graft of femur intertrochanteric fracture due to non-union. Anesthesia was induced with thiopental and succinylcholine and maintained with vecuronium- Halothane-nitrous oxide-oxygen. Three uints whole blood was transfused and any significnat change in vital signs and EKG were not found during 4 hours operation. Soon after the patient was recovered. But he was found to be hemiplegia and sensory disturbance on the next day. Brain CT revealed infarction of middle cerebral artery territory. He expired 7 days following the surgery despite strenuous supportive measure.

The silicon tracheal T-tube was designed to maintain an adequate tracheal airway as well as to provide support in the stenotic trachea which has been reconstructed. Replacement of the T-tube was obviously undesirable following recent reconstruction of an unstable fracture of the airway. The loss of anesthetic gas through a T-tube while it is in place during anesthesia has been a problem. This report describes a simple method of establishing a satisfactory airway in a patient with a tracheal T-tube, and reviews the anesthesia aspects of modern surgical reconstruction of the larynx and cervical traches.

The Na+ -K+ -activated ATPase is required to maintain osmotic balance and stabilize cell volume. The Na+ -K+ -ATPase has a more direct role in regulating cell volume; it controls the solute concentrations inside the cell, thereby regulating the osmotic forces that can make a cell swell or shrink. The impotance of the Na+ -K+ -ATPase in controlling cell volume is indicated by the observation that animal cells swell, and may burst, if they are treated with ouabain, which, inhibits the Na+ -K+ -ATPase. The present experiment was designed and carried out to determine the effect of verapamil, a calcium blocker, on the activity of Na+ -K+ -ATPase prepared from renal medulla in the normal rabbit. It was reported that verapamil, a well known coronary vasodilator, possessed negative inotropic effects. The mechanism of action of verapamil was initially thought to be due to coronary vasodilation and blockade of myocardial B-adrenergic receptors. 1t was termed such agent calcium antagonist. A derivative of verapamil, D-600, was subsequently shown to block the movement of calcium through the slow channel and thereby after the plateau phase of the cardiac action potential. Verapamil do not directly antagonize the effects of calcium. Rather, it inhibit the entry of ealcium into cells or its mobilization form intracellular stores and, as such, have been termed a calcium channel blocker.
