Abstract

Endobronchial blood clots or mucus plugs can present with minimal symptoms or acute airway obstruction in the intensive care unit (ICU) patients. Acute airway obstruction can lead to rapid worsening of dyspnea owing to poor oxygenation due to collapse of the lung. Prompt recognition and treatment of this condition can translate into a successful outcome by decreasing morbidity and mortality and facilitating successful weaning of these patients. When conventional methods fail to relieve the obstruction, cryoextraction a novel technique, may prove to be a useful alternative for the removal of these clots and mucus plugs. Cryoextraction is best performed with rigid bronchoscopic intubation. However, in certain conditions, it may be used with a flexible fiberoptic bronchoscope (FOB) through an endotracheal tube, especially when bedside procedure is required in ICU patients. In this series, three cases are being discussed where bedside flexible bronchoscopy-guided cryoextraction was done leading to a successful resolution of acute hypoxemic respiratory failure.
