To define the effect of the knee-chest position on pulmonary oxygenation in patients who underwent lower spinal operations under spinal anesthesia. ⋯ A significant improvement of pulmonary oxygenation was seen in elderly patients who underwent lower spinal operation with spinal anesthesia when they were turned to the knee-chest position. The knee-chest position has a beneficial effect on pulmonary oxygenation in elderly patients who are given spinal anesthesia.

Case Reports
Epidural anesthesia for a cesarean section in a patient with pulmonary atresia and ventricular septal defect.
The perioperative management and the pathophysiology of a parturient with pulmonary atresia, ventricular septal defect, patent ductus arteriosus Botalli (PDA), and pulmonary hypertension are described. The patient previously had a cesarean section under general anesthesia and was currently managed with an epidural block. The outcome was successful for the mother. The postoperative period of the premature infant was characterized by hyaline membrane disease, with its typical sequelae.

Randomized Controlled Trial Clinical Trial
Maternal and neonatal effects of adding epidural sufentanil to 0.5% bupivacaine for cesarean delivery.
To determine the maternal and fetal effects of the addition of epidural sufentanil to 0.5% bupivacaine for cesarean delivery. ⋯ The epidural injection of sufentanil added to 0.5% bupivacaine with epinephrine improved the quality of anesthesia during elective cesarean section without jeopardizing the safety of the baby.

The widely practiced rapid-sequence induction with application of cricoid pressure is designed to facilitate endotracheal intubation in patients considered to be at high risk of aspiration. We describe a case in which this maneuver was performed on a patient with an undiagnosed traumatic injury to the larynx. The resulting airway obstruction required emergency surgical intervention. The clinical presentation, diagnosis, and management of such injuries are discussed.
