To examine whether increasing mean arterial pressure (MAP) with the administration of phenylephrine would improve internal jugular venous oxygen saturation (SjvO2) during normothermic cardiopulmonary bypass (CPB) in patients with preexisting stroke. ⋯ Increasing MAP improves SjvO2 in patients with or without preexisting stroke during normothermic CPB.

Case Reports
An initially unnoticed piece of nasal jewelry in a parturient: implications for intraoperative airway management.
The literature documenting the anesthetic implications of body piercing consists only of a few case reports that focus exclusively on interference with airway management by oral jewelry. To date, no case reports documenting anesthetic problems resulting from the presence of nasal jewelry have been reported. ⋯ This situation necessitated fiberoptic examination of the nasopharyngeal and oropharyngeal cavities and radiologic imaging studies to rule out aerodigestive tract aspiration of retained and missing piece(s) of the jewelry. Based on this experience, we now advise all laboring parturients with nasal or oral jewelry in situ to remove the hardware on admission to Labor and Delivery for safety precautions.

Spinal cord injuries continue to be a devastating medical problem. By impairing voluntary and involuntary nervous system function, virtually every body system function is affected. However, pulmonary function alteration and respiratory complications continue to be the major causes of morbidity and mortality in patients with spinal cord injuries. The current understanding of respiratory problems faced by patients with loss of innervation from cervical spinal cord injuries are reviewed.

Randomized Controlled Trial Clinical Trial
Tracheoscopy with the rapiscope to verify endotracheal tube placement.
To determine whether tracheoscopy is an accurate and quick method for verifying correct placement of the tracheal tube after intubation. ⋯ Tracheoscopy is a reliable method for quickly verifying proper endotracheal placement of a tracheal tube.

Inhaled nitric oxide is a selective pulmonary vasodilator that has been used successfully to treat hemodynamic embarrassment and right-to-left interatrial shunting in acute right heart failure. Previous reports have been in the setting of disorders causing elevated right heart afterload, such as pulmonary embolism, acute respiratory distress syndrome, and chronic obstructive pulmonary disease. ⋯ We report a patient with right ventricular infarction for whom cardiogenic shock and refractory hypoxemia due to right-to-left interatrial shunting were effectively treated with inhaled nitric oxide. The potential for broader application of inhaled nitric oxide as a therapy for right ventricular infarction is discussed.
