Ventilation during bronchoscopy.

چکیده
FOR BRONCHOSCOPY in the past, various techniques have been used for anaesthesia: ( 1 ) Bronchoseopy without anaesthesia can be used only on infants or moribund patients, mainly for the purpose of providing tracheobronchial toilet. Special techniques of restraint must be used. A thorough diagnostic examination of the tracheobronchial tree is not possible. (2) Bronchoscopy with local anaesthesia a requires that the patient is sufficiently co-operative to permit the administration of the local anaesthetic and sufficiently relaxed to permit proper positioning of the head in relation to the thorax for the performance of the examination. Again, premedication is critical as it has to provide pain relief and apathy without undue depression and still leave the bronchoscopist with a co-operative patient. Other problems are the untoward reactions to the local anaesthetic agent used, idiosyncratic and overdosage, remembering that the toxicity of local anaesthetic agents is the same when given endotracheally as when given intravenously. 2 (3) With general anaesthesia the bronehoscopist and the anaesthetist share the airway; each one has access to it only intermittently and some compromise is required to maintain ventilation and perform the examination. The following techniques have evolved:

Controlled vs Spontaneous Ventilation for Bronchoscopy in Children with Tracheobronchial Foreign Body
Introduction Tracheobronchial foreign body aspiration is a common life-threatening condition in children. There are controversies in the management of this condition, including the type of ventilation during bronchoscopy. This study aims to compare anesthesia with controlled ventilation versus spontaneous ventilation in rigid bronchoscopy in children with foreign body aspiration. Materials...

متن کاملBronchoscopy during noninvasive ventilation: indications and technique.
Diagnostic or therapeutic flexible bronchoscopy is often necessary in severely ill patients. These patients often have comorbidities that increase the risk of bronchoscopy-related complications. Noninvasive ventilation might decrease the risk of these complications in patients with severe refractory hypoxemia, postoperative respiratory distress, or severe emphysema, and in pediatric patients. N...
متن کاملFiber optic bronchoscopy in patients with acute hypoxemic respiratory failure requiring noninvasive ventilation - a feasibility study
INTRODUCTION Noninvasive ventilation (NIV) is a standard procedure in selected patients with acute respiratory failure. Previous studies have used noninvasive ventilation to ensure adequate gas exchange during fiberoptic bronchoscopy in spontaneously breathing hypoxemic patients, thus avoiding endotracheal intubation. However, it is unknown whether bronchoscopy can be performed safely in patien...
