The hyperpolarizatlon-activated current (If) was recorded from single myocytes dissociated from rabbit sinoatrial node. Although If is usually carried by both Na+ and K+, removal of the minor K+ component from physiological saline suppresses inward component. This inward Na+ current through If channel increases on raising the extracellular K+ concentration.(More)
Sixty-six patients scheduled for coronary artery bypass graft and/or valve surgery were recruited in a prospective, randomized study designed to compare the effectiveness of three analgesic regimens for chest drain removal. Patients were randomized to receive 0.1 mg/kg IV morphine, 20 mL of 0.5% bupivacaine infiltrated subcutaneously, or inhaled 50% nitrous(More)

That there needs to be a facial palsy before there can be a platysma palsy is strongly suggested, in that there was no case of an isolated platysma palsy. Patients, regardless of age or other factors,(More)
High-volume, low-pressure tracheal cuffs of disposable double lumen tubes may offer limited protection to the dependent lung if fluid leaks through folds in the inflated cuffs. This study was undertaken to determine the incidence of fluid leakage past the tracheal cuff and whether gel lubrication reduces the incidence. Fifty-five patients were randomly(More)
