endotracheal tube (ett) cuff herniation is a rare, and often difficult to diagnose, cause of bronchial obstruction. we present a case of outside cuff herniation of an endotracheal tube that caused pulmonary right lung atelectasis. a 29-year-old man ,a case of car accident with multiple fractures, was admitted to the emergency ward and transferred to the operating room(or) for open reduction and...

1050 April 2014 We read not only with interest but also with some surprise the review on high intraoperative oxygen concentration by Hovaguimian et al.1 that appeared recently in AnestHesiology. The authors selected 9 to 11 of 21 studies and by a meta-analysis they concluded that “intraoperative high inspired oxygen fraction decreases the risk of surgical-site infection in surgical patients rec...

ultrasound-conductive substance (e.g., water, pus, blood, and fibrous tissue), the withdrawal of air (e.g., resorption atelectasis) will also lead to the genesis of B lines. Demonstrating this last point, in an ex vivo animal model of graded atelectasis, B lines were observed in increasing numbers with increasing atelectasis. Pathologic examination of the excised lungs showed diffusely compress...

BACKGROUND Intraoperative high inspired oxygen fraction (FIO2) is thought to reduce the incidence of surgical site infection (SSI) and postoperative nausea and vomiting, and to promote postoperative atelectasis. METHODS The authors searched for randomized trials (till September 2012) comparing intraoperative high with normal FIO2 in adults undergoing surgery with general anesthesia and report...

Several intraoperative ventilation strategies are available for obese patients. However, the same ventilation interventions have exhibited different effects on PaO2 /FIO2 concerning obese patients in different trials, and the issue remains controversial. Therefore, we conducted a network meta-analysis to identify the optimal mechanical ventilation strategy. We searched the Cochrane Central Regi...

General anesthesia is known to cause pulmonary atelectasis; in turn, atelectasis increases shunt, decreases compliance, and may lead to perioperative hypoxemia. One mechanism for the formation of atelectasis intraoperatively is ventilation with 100% oxygen. The goal of this review is to determine if research suggests that intraoperative ventilation with 100% oxygen leads to clinically significa...

of 100% oxygen during induction and emergence is standard practice for the vast majority of anesthetists, our study reflects the impact of high intraoperative inspired oxygen in actual practice. The use of 100% oxygen for induction and emergence also likely had minimal effect on our results because the degree of atelectasis induced by administration of 100% oxygen for only a few minutes is rela...
