Large volume, low pressure endotracheal tube cuffs are claimed to have less deleterious effect on tracheal mucosa than high pressure, low volume cuffs. Low pressure cuffs, however, may easily be overinflated to yield pressures that will exceed capillary perfusion pressure. Various large volume cuffed endotracheal tubes were studied, including Portex Profile, Searle Sensiv, Mallinkrodt Hi-Lo, an...

BACKGROUND Surgery is an appropriate therapeutic approach for tracheal stenosis due to various benign and malignant conditions. When surgery is postponed for certain reasons, other options are chosen for airway patency. One alternative is using airway stents. OBJECTIVES We aimed to introduce a safe method of tracheal polyflex stent placement in patients with tracheal stenoses. PATIENTS AND ...

Tracheostomy may be associated with numerous acute, perioperative complications, some of which continue to be relevant well after the placement of the tracheostomy. A number of clinically important unique late complications have been recognized as well, including the formation of granulation tissue, tracheal stenosis, tracheomalacia, tracheoinnominate-artery fistula, tracheoesophageal fistula, ...

introduction: response to tracheal tube during emergence of general anesthesia is a main concern. we aimed to compare the effect of remifentanil and lidocaine on response to tracheal tube during emergence of general anesthesia. materials and methods: in this randomized clinical trial, we enrolled 80 consecutive patients with american society of anesthesiology (asa) physical status i–ii, who und...

RATIONALE Primary tracheal adenoid cystic carcinoma of the trachea primary is a rare neoplasm and commonly misdiagnosed. Lung isolation during surgery and ventilation pose a tremendous challenge to anesthesiologists. PATIENT CONCERNS The authors describe a novel technique of lung isolation and ventilation with a Univent tube during thoracoscopic mediastinal tracheal resection and reconstructi...

BACKGROUND This randomized single-blinded, cross-over study was done to evaluate the influence of the size of tracheal tubes on air leaks around the cuffs. METHODS In a benchtop model, the number of longitudinal folds on the cuffs was evaluated for different sizes of tracheal tubes. In an anesthetized patient study, thirty patients scheduled for elective surgery under general anesthesia were ...
