[Controlled clinical trial "blind" versus aimed fibrebronchoscopic suction in mechanically ventilated patients
Abstract:
In patients treated with ventilation therapy only 60% of blind suction catheters reach the desired position. In ten patients the routinely performed blind suction was replaced by aimed bronchoscopic suction. Blood gas analyses before and after aimed and blind suction favoured the former. Also the arterioalveolar oxygen tension difference showed a good response to aimed suction. There is a broad spectrum of indications for fibreoptic bronchoscopy in every care unit dealing with mechanical ventilation.
