Extradural hematoma following double valve replacement under cardiopulmonary bypass: A rare complication.

The primary mechanisms responsible for acute neurological deterioration following cardiopulmonary bypass (CPB) include cerebral embolism, cerebral hypoperfusion and/or inflammatory process triggered by CPB. Extradural hematoma (EDH) following CPB is rare but associated with significant mortality and morbidity. We present a case of EDH following double valve replacement in an adolescent boy.

Anesthetic management of a patient with hypertrophic obstructive cardiomyopathy with dual-chamber pacemaker undergoing transurethral resection of the prostate.

We describe the anesthetic management of a patient with hypertrophic obstructive cardiomyopathy with dual-chamber pacemaker undergoing transurethral resection of the prostate. Anesthetic challenges included prevention and management of perioperative arrhythmias, maintenance of adequate preload, afterload and heart rate to relieve left ventricular outflow tract obstruction and considerations related to the presence of dual-chamber pacemaker and TURP. We recommend preoperative reprogramming of the DDD pacemaker, avoidance of magnet application during the procedure, application of electrosurgical unit current returning pad to the anterior aspect of the thigh, especially if monopolar cautery is used, use of central venous pressure line for estimation of preload and careful titration of anesthetic drugs to maintain stable hemodynamics.

ST elevation - An indication of reversible neurogenic myocardial dysfunction in patients with head injury.

This report describes a patient who presented with signs of meningitis four days after head injury. The patient had ST elevation on electrocardiography along with hypotension and positive tropinin T test, mimicking inferior wall infarction. The ST changes resolved within 48 hours of intensive care management. Subsequent investigations failed to document any myocardial infarction.
