11/1290. The outcome after perinatal management of infants with potential airway obstruction.Masses in the head and neck are being detected prenatally with increasing frequency, necessitating the need for management of potential upper airway obstruction at delivery. Establishment of the airway at delivery and its maintenance thereafter are critical. This should optimally be performed with the baby still attached to the placental circulation. The importance of multidisciplinary team management, including a high risk obstetrician, neonatologist, pediatric otolaryngologist, pediatric thoracic surgeon, and an anesthetist, cannot be overemphasized. Endotracheal intubation is attempted first, if unsuccessful then is followed by insertion of a rigid bronchoscope. tracheotomy should be reserved for airway obstructions, which are not amenable to endotracheal intubation or in babies in whom exchange from a bronchoscope to endotracheal tube cannot be safely performed. The management of six infants with prenatally diagnosed potential airway obstruction is presented. morbidity and mortality still ultimately depend on the severity of the existent anomalies.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |
12/1290. Negative pressure pulmonary hemorrhage.Negative pressure pulmonary edema, a well-recognized phenomenon, is the formation of pulmonary edema following an acute upper airway obstruction (UAO). To our knowledge, diffuse alveolar hemorrhage has not been reported previously as a complication of an UAO. We describe a case of negative pressure pulmonary hemorrhage, and we propose that its etiology is stress failure, the mechanical disruption of the alveolar-capillary membrane.- - - - - - - - - - ranking = 0.14285714285714keywords = obstruction (Clic here for more details about this article) |
13/1290. infectious mononucleosis and bilateral peritonsillar abscesses resulting in airway obstruction.Upper airway obstruction is an uncommon but recognized complication of infectious mononucleosis. The management depends upon the degree of airway compromise. In the case described, severe airway obstruction was treated by securing the airway with awake fibre-optic endoscopic intubation and then proceeding to tonsillectomy. Bilateral inferiorly loculated quinsies were encountered unexpectedly and drained. This is the first report of 'bilateral' quinsies, associated with infectious mononucleosis and severe airway obstruction. The association, pathogenesis and significance of this finding are also discussed.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |
14/1290. The answer is blowing in the wind: a pedunculated tumour with saw tooth flow-volume loop.Obstructing tumours of the upper airways have been demonstrated to alter the flow volume loop of pulmonary function testing. These alterations could be clues to the nature and location of the obstruction. This report describes a case of a pedunculated squamous cell carcinoma arising in the pharynx whose flow volume loop showed a saw tooth pattern which reflected the location and structure of the tumour.- - - - - - - - - - ranking = 0.14285714285714keywords = obstruction (Clic here for more details about this article) |
15/1290. Localised upper airway obstruction in a patient with acquired immunodeficiency syndrome.We describe a case of rapidly progressive upper airway obstruction due to tracheal Pseudomonas abscesses in a patient with acquired immunodeficiency syndrome. The case highlights the aggressive nature of pseudomonas infections and the difficulty of eradicating this organism in patients infected with the human immunodeficiency virus.- - - - - - - - - - ranking = 0.71428571428571keywords = obstruction (Clic here for more details about this article) |
16/1290. Helical computed tomographic minimum-intensity projection of a slit in an airway obstruction.We treated a 54-year-old man with an anastomotic obstruction after a right upper sleeve lobectomy. By using minimum intensity projection images that were generated from helical computed tomographic data sets that indicated a twisted slit enhanced with air a few millimeters in length, through anastomosis to the distal bronchus, we successfully treated the obstruction by bronchoscopic balloon dilatation.- - - - - - - - - - ranking = 0.85714285714286keywords = obstruction (Clic here for more details about this article) |
17/1290. Percutaneous dilatational tracheostomy in a patient with thyroid cancer and severe airway obstruction.A patient with extensive metastatic thyroid cancer scheduled for palliative tracheostomy is presented. He had laryngeal dislocation with severe airway obstruction and few anatomical landmarks due to tumour infiltration and radiation. Successful percutaneous dilatational tracheostomy was performed under local anaesthesia.- - - - - - - - - - ranking = 0.71428571428571keywords = obstruction (Clic here for more details about this article) |
18/1290. Delayed massive hemoptysis after expandable bronchial stent placement.patients with lung cancer often develop airway obstruction that necessitates palliative bronchoscopic interventions. Expandable metal stents are increasingly used for this indication. We report a case of fatal massive hemoptysis that occurred 1 week after uneventful bronchial stent placement. Previous treatment with external-beam radiotherapy, brachytherapy, and photodynamic therapy probably contributed to pulmonary artery-bronchial fistulization in this patient. This complication should be kept in mind when considering expandable airway stent insertion in heavily pretreated lung cancer patients.- - - - - - - - - - ranking = 0.14285714285714keywords = obstruction (Clic here for more details about this article) |
19/1290. Anesthetic considerations of two sisters with beckwith-wiedemann syndrome.Anesthetic considerations of 21-mo-old and 4-yr-old sisters with beckwith-wiedemann syndrome during surgical repair of cleft palate and reduction of macroglossia are presented and discussed. This syndrome is characterized by exomphalos, macroglossia, gigantism, hypoglycemia in infancy, and many other clinical features. This syndrome is also known as exomphalos, macroglossia, and gigantism (EMG) syndrome. Principal problems associated with anesthetic management in this syndrome are hypoglycemia and macroglossia. Careful intraoperative plasma glucose monitoring is particularly important to prevent the neurologic sequelae of unrecognized hypoglycemia. It is expected that airway management would be complicated by the macroglossia, which might cause difficult bag/mask ventilation and endotracheal intubation following the induction of anesthesia and muscle paralysis, so preparations for airway difficulty (e.g., awake vocal cord inspection) should be considered before induction. A nasopharyngeal airway is useful in relieving postoperative airway obstruction.- - - - - - - - - - ranking = 0.14286424038707keywords = obstruction, duct (Clic here for more details about this article) |
20/1290. Psychogenic stridor: a cause of acute upper airway obstruction.A 17-year-old boy was seen in the emergency department with signs and symptoms of acute upper airway obstruction, closely resembling epiglottitis. Immediate management consisted of induction of general anesthesia with spontaneous ventilation. Because no organic pathologic process was found, and in combination with subsequently known psychosocial stressors, a diagnosis of psychogenic stridor, a conversion disorder, was made. Conversion disorders may be seen by the busy family practitioner or pediatrician and are frequently underdiagnosed.- - - - - - - - - - ranking = 0.71428808012902keywords = obstruction, duct (Clic here for more details about this article) |
