The effect of ketamine alone and in combination with N2O (70% inspired) on median nerve somatosensory evoked potentials (SSEPs) was investigated in 16 neurologically normal patients undergoing elective abdominopelvic procedures. The anesthetic regimen consisted of ketamine (2 mg/kg iv bolus followed by continuous infusion at a rate of 30… (More)
BACKGROUND Intraoperative echocardiography is a valuable monitoring and diagnostic technology used in cardiac surgery. This reports our clinical study of the usefulness of intraoperative echocardiography to both surgeons and anesthesiologists for high-risk coronary artery bypass grafting. METHODS From March to November 1995, 82 consecutive high-risk… (More)
BACKGROUND The study evaluated the efficacy of recombinant human antithrombin (rhAT) for restoring heparin responsiveness in heparin resistant patients undergoing cardiac surgery. METHODS This was a multicenter, randomized, double-blind, placebo-controlled study in heparin-resistant patients undergoing cardiac surgery with cardiopulmonary bypass. Heparin… (More)
BACKGROUND Oral practice examinations (OPEs) are used in many anesthesiology programs to familiarize residents with the format of the oral qualifying examination given by the American Board of Anesthesiology (ABA). The purpose of this communication is to describe the planning, structure, startup, administration, growth and evaluation of a comprehensive oral… (More)
Bilateral sequential lung transplantation is now an accepted therapy for patients with end-stage cystic fibrosis. In our experience, the use of a standard double-lumen endotracheal tube to establish one-lung ventilation during bilateral lung transplantation has been associated with difficulty in clearing the airway of the thick, tenacious secretions… (More)
Postintubation tracheal stenosis presents major challenges to the anesthesiologist, especially in situations where the airway is shared with the surgeon. The airway management of a patient with severe postintubation subglottic stenosis, who developed complete airway obstruction during attempted tracheal dilatation, is presented.
Although the effect of systemic opioids on somatosensory evoked potentials has been well described, little is known about the interaction between intrathecally administered opioid analgesics and somatosensory evoked potentials. Accordingly, the influence of intrathecally administered morphine on posterior tibial nerve somatosensory cortical evoked… (More)
