Full Airway Drainage by Fiber Bronchoscopy Through Artificial Airway in the Treatment of Occult Traumatic Atelectasis.

The objective of this study is to investigate the effects of full airway drainage by fiber bronchoscopy through artificial airway in the treatment of traumatic atelectasis with occult manifestations. From May 2006 to May 2011, 40 cases of occult traumatic atelectasis were enrolled into our prospective study. Group A (n = 18) received drainage by nasal bronchoscope; group B underwent airway drainage by fiber bronchoscopy through artificial airway (n = 22). The effects of treatment were evaluated by the incidence of adult respiratory distress syndrome (ARDS), lung abscess, and the average length of hospital stay. Compared with nasal fiber-optic treatment, airway drainage by fiber bronchoscopy through artificial airway reduced the incidence of ARDS (p = 0.013) and lung abscess (p = 0.062) and shortened the mean length of stay (p = 0.018). Making the decision to create an artificial airway timely and carry out lung lavage by fiber bronchoscopy through artificial airway played a significant role in the treatment of occult traumatic atelectasis.
