    Abstract:
    Sputum retention causing pulmonary atelectasis, secondary pneumonia, and respiratory failure is a frequent complication particularly in patients recovering from abdominal and thoracic surgery. Physiotherapy and conventional therapeutic means like blind tracheobronchial and bronchoscopic suction applied to prevent and treat postoperative respiratory complications have been shown to not be completely effective. Minitracheotomy is a new alternative method for the treatment of sputum retention. Endobronchial suction can be performed as often as required, using a thin uncuffed tube (ID 4.5 mm) which is inserted into the trachea through the cricothyroid membrane under local anaesthesia. Since respiration occurs normally through the nose, mouth, and larynx these patients retain speech and the ability to cough. Complications are rare. Endobronchial suction via minitracheotomy is minimally invasive, more comfortable, and at least as effective as conventional bronchoscopic suction. It therefore has become a routine method used in the treatment of postoperative sputum retention in high-risk patients in many intensive-care units.
