Abstract
Minitracheotomy (MT) is a new method for the treatment of sputum retention and atelectasis. Through a I–cm incision in the cricothyroid membrane (coniotomy), a specially designed tube is placed in the trachea, allowing suction to be performed. Fifteen patients, aged 37–78 years (median 62 years), with postoperative sputum retention, atelectasis and imminent respiratory failure, were treated with suction by MT. Thirteen of the patients recovered from their respiratory problems, while two patients had to be treated with intermittent positive pressure ventilation (IPPV). During insertion, one case of external bleeding and one–case of subcutaneous and mediastinal emphysema were seen, while no complications were seen during cannulation. The duration of cannulation was 4–38 days (median 10 days). Following decannulation the incisions were airtight within 1 day and healed within 3 days. Ten patients left hospital in good health and five died because of surgical complications and/or cardiovascular failure. MT seems to be effective in the treatment of sputum retention and atelectasis. Advantages over other invasive methods make it a method of first choice. The method involves few complications and is often so effective that avoidance of intubation and IPPV is possible.
