Case ReportsSuccessful one-lung ventilation in a patient with the Fontan circulation undergoing thoracotomy: a case report.
The incidence of noncardiac surgery in patients with the Fontan circulation has increased over the years due to the elongated life expectancy of these patients. In patients with the Fontan circulation, pulmonary blood flow is passive, so it is important to keep pulmonary vascular resistance low. One-lung ventilation (OLV) can have adverse effects on the Fontan circulation due to hypoxia, hypoxic pulmonary vasoconstriction, hypercarbia, and increased airway pressure. We present a case of successful OLV in a patient with the Fontan circulation and describe our perioperative management.

Effect of jaw thrust and cricoid pressure maneuvers on glottic visualization during GlideScope videolaryngoscopy.
During performance of direct laryngoscopy in the difficult-to-visualize airway, several maneuvers have the potential to impact glottic visualization, including jaw thrust and cricoid pressure. The effect of these maneuvers on glottic visualization during videolaryngoscopy has not been studied. We evaluated the effect of jaw thrust and cricoid pressure maneuvers on both visualization of the glottis and the area of glottic opening visible during GlideScope-aided videolaryngoscopy. ⋯ The jaw thrust maneuver was superior to videolaryngoscopy alone in improving the modified C&L grade and the visualized glottic area; however, no significant improvement was noted with cricoid pressure. We therefore recommend the use of jaw thrust as a first-line maneuver to aid in glottic visualization and tracheal intubation during GlideScope videolaryngoscopy.

Case ReportsCase report: central venous catheterization via internal jugular vein with associated formation of perioperative venous thrombosis during surgery in the prone position.
An unusual case of central venous catheter (CVC)-related thrombosis during supine surgery in the prone position is presented. A 76-year-old woman was scheduled for elective surgery to repair a broken lumbar instrument. A single-lumen CVC was inserted via the right internal jugular vein. ⋯ The presence of the internal jugular venous catheter may have created thrombogenic conditions. A patient's position during surgery can reduce deep venous-flow velocity, and venous blood may stagnate, contributing greatly to thrombogenicity. We should consider a patient's position during surgery as a risk factor for thrombus formation, and a careful preoperative evaluation should be made as to which route should be chosen for CVC.
