We performed a case-controlled, double-blind study to examine the performance of three multivariate clinical models (Wilson, Arné, and Naguib models) in the prediction of unanticipated difficult intubation. The study group consisted of 97 patients in whom an unanticipated difficult intubation had occurred. For each difficult intubation patient, a matched(More)
A prospective randomized controlled study was designed to determine differences in early postoperative pulmonary function, pain, and complications between patients undergoing limited lateral muscle-sparing thoracotomy. Fifteen patients underwent standard thoracotomy and 13 underwent limited incision with the same anesthetic technique. During the first 24(More)
PURPOSE OF REVIEW Interventional pulmonology is a rapidly expanding field offering less invasive therapeutic procedures for significant pulmonary problems. Many of the therapies may be new for the anesthesiologist. Although less invasive than surgery, some of these procedures will carry significant risks and complications. The team approach by(More)
Major airway obstruction due to broncholithiasis produces significant morbidity, and management is difficult. Many of the patients are elderly and are not good candidates for surgical removal. Bronchoscopic removal may be limited due to anatomic considerations, skill of the bronchoscopist, and exposure of the patient to additional procedural risks.(More)
BACKGROUND Balloon dilatation (BD) is a useful method of treating tracheobronchial stenosis (TBS); however, accurate preoperative identification of the lesion is difficult. Three-dimensional computed tomography (3D-CT) is an imaging method that may allow more accurate definition of the lesion(s) preoperatively. STUDY OBJECTIVE It is the aim of this study(More)
PURPOSE Small animal micro-CT imaging is being used increasingly in preclinical biomedical research to provide phenotypic descriptions of genomic models. Most of this imaging is coincident with animal death and is used to show the extent of disease as an end point. Longitudinal imaging overcomes the limitation of single time-point imaging because it enables(More)
PURPOSE OF REVIEW Literature about thoracic surgery in patients with pulmonary hypertension is scarce. Perceived high risk has appropriately discouraged any unnecessary operation. However, the medical therapy for pulmonary hypertension has made great advances during the last decade. It is likely that future advances in survival and possibly the need for(More)
P NEUMOTHORAX is an uncommon but potentially serious occurrence during anesthesia. Initial clinical signs may be subtle, but progression to a tension pneumothorax can result in significant cardiorespiratory instability. Because therapy for pneumothorax may require invasive chest tube placement, definitive diagnosis by chest radiography is necessary.(More)
