Background A high perioperative inspiratory oxygen fraction may reduce the risk of surgical site infections, as bacterial eradication by neutrophils depends on wound oxygen tension. Two trials have shown that a high perioperative inspiratory oxygen fraction (FiO2=0.80) significantly reduced risk of surgical site infections after elective colorectal surgery, but a third trial was stopped early [...]

Solitary fibrous tumor (SFT) of the pleura is an uncommon intrathoracic neoplasm. A middle-aged woman had progressive exertional dyspnea for 6 months, and eventually respiratory failure developed which necessitated ventilatory support. After examination, a giant tumor was found to occupy the whole left pleural cavity with chest wall distention and severe mediastinal shift to the [...]
