tracheal stenosis/hypoxia

Rats with different resistance to hypoxic hypoxia differ in parameters of their acid-base state: in high resistance, lower values for blood pH are recordable together with slightly higher pCO2 and content of non-volatile acids. Development of experimental stenosis of trachea in low- and

Hypoxia is an important mechanism involved in dermal scar formation. Post-intubation tracheal stenosis (PTS) has similar pathological characteristics and formation mechanisms to skin hypertrophic scars. Hypoxia-inducible factor‑1α (HIF‑1α) is a nuclear transcription factor that facilitates the

A twenty-year-old girl was referred with tracheal stenosis (TS) which was a consequence of prolonged intubation after head injury because of previous car accident. The patient was aphasic and had normal respiration. Fiberoptic bronchoscopy showed complete tracheal obstruction at second tracheal ring

Development of hypoxic hypoxia in stenosis of the larynx and cervical trachea of different etiology leads to respiratory insufficiency and bioenergetic impairment. Investigation of blood gas composition and acid-base balance in patients with laryngeal and tracheal stenosis determines severity of

Severe tracheal stenosis, resulting in functional atresia of the trachea is a rare congenital malformation with an estimated occurrence of two in 100,000 newborns. If no esophagotracheal fistula is present to allow for spontaneous breathing, this condition is usually fatal. We report on a male

We report a successful use of the i-gel for tracheostomy in a patient with severe neck deformity and tracheal stenosis. A 20-year-old man, 142 cm, 22 kg, was scheduled for tracheotomy. He had tracheal stenosis with hypoxemia, due to the pressure from the brachiocephalic artery, associated with

Congenital tracheal stenosis is an uncommon but life-threatening condition whose management is still debated. The rarity of this disease explains the lack of a standard management. Between 1986 and 1996, eight children younger than 1 year were referred to our Institution with a tracheal stenosis.

BACKGROUND Stenting of airway stenosis is a common procedure in specialized centers. The aim of this study was to summarize our clinical experience in ventilation strategy and anesthesia management of patients undergoing urgent tracheal stenting. METHODS Clinical data of 22 patients with severe

Postintubation stenosis is the most frequent cause of benign tracheal stenosis and may cause reintubation and delay in weaning of intensive care unit patients. This case study describes typical patients with tracheal stenosis and the management of these patients. Five patients requiring reintubation

BACKGROUND To describe the successful management of a patient with severe dyspnea and hypoxia due to tracheal stenosis by the application of a novel bridging technique-anterograde tracheal catheterization-prior to tracheostomy. METHODS A 55-year-old woman entered the Emergency Department with severe

OBJECTIVE To analyze the outcomes of patients undergoing repair of congenital tracheal stenosis. METHODS This was a retrospective review of congenital tracheal stenosis patients treated between 2001 and 2007 at the University of São Paulo School of Medicine Hospital das Clínicas in São Paulo,

We report the anesthetic management of a 65-year-old woman with recurrent, severe tracheal stenosis who underwent tracheal dilatation. She had visited the Department of Respiratory Medicine at our hospital for respiratory distress approximately 20 years ago, and had undergone laser ablation under

Perioperative airway management for sleeve pneumonectomy in a 66-year-old female with tuberculous tracheal stenosis which was 2 cm above the carina to the right main bronchial orifice is reported. Endotracheal intubation was required, because she complained of dyspnea due to airway stenosis in

We here report a case in which tracheal stent insertion was performed using veno-venous extracorporeal membrane oxygenation (V-V ECMO). A 78-year-old man with severe tracheal stenosis due to thyroid cancer was suffering from dyspnea at rest. Computed tomography showed that the narrowest caliber of

Medication, intracranial hemorrhage, infarction, infection, hypoxia, organ failure, and nutritional deficiency may cause unconsciousness following successful emergence from anesthesia. A 39-year-old woman with a history of tracheal stenosis, depression, and anxiety had complete unconsciousness on 3
