Tracheal vascular dilatation elicited by vagal nerve stimulation in rats.
We investigated the effects of the electrical stimulation of a unilateral cervical vagal nerve on the blood flow in the trachea using laser Doppler flowmetry in urethane anesthetized Wistar King rats. Stimulation for 30 s at 1, 2, 5, 10, 20 or 50 Hz with 10 V intensity caused an increase in tracheal blood flow (TBF) in a frequency-dependent manner; the effects were most dominant with the 10-Hz ...
متن کاملInvolvement of inhibitory innervation in reflex tracheal dilatation induced by lung inflation.
We investigated the involvement of inhibitory innervation in reflex tracheal dilatation (RTD) induced by inflating the lungs in dogs. RTD was inhibited about 50% by 100 micrograms propranolol injected into the cranial thyroid artery, but was unaffected by adrenalectomy. Residual RTD under beta-blockade was abolished by sections of both the bilateral superior laryngeal nerves and spinal cord at ...
متن کاملBronchoscopic balloon dilatation for tuberculosis-associated tracheal stenosis: a two case report and a literature review
BACKGROUND Bronchoscopic balloon dilatation (BBD) is a common strategy in the treatment of bronchostenosis. However, the longer dilating time in each inflation cycle (approximately 3-5 min) without mechanical ventilation is not possible for the treatment of tracheal stenosis. CASE PRESENTATION In this study, we reported our experience of BBD with shorter dilating time (10 s or 1 min) and inte...
متن کاملManagement of Benign Tracheal Stenosis by Small-diameter Tube-assisted Bronchoscopic Balloon Dilatation
BACKGROUND A limitation of bronchoscopic balloon dilatation (BBD) is that airflow must be completely blocked for as long as possible during the operation. However, the patient often cannot hold his or her breath for a long period affecting the efficacy of the procedure. In this study, we used an extra-small-diameter tube to provide assisted ventilation to patients undergoing BBD and assessed th...
متن کاملEffect of tracheal dilatation and rupture on mechanical ventilation using a low-pressure cuff tube.
We report the case of a 36-year-old woman who suffered tracheal dilatation and rupture despite careful monitoring of intracuff pressure. Surgical manipulation, postoperative mediastinitis, and bacterial staphylococcal tracheitis may be involved in the development of this complication.
