Postoperative impairment of mucous transport in the lung
Gamsu, G; Singer, M M; Vincent, H H; Berry, S; Nadel, J A
Impairment of mucous transport is considered significant to the postoperative development of atelectasis, but the association has never beed demonstrated in humans. Tantalum powder, which adheres to airway mucus, can be used to study mucociliary transport. The postoperative clearance of insufflated tantalum powder (mean diameter, 2.5 mum) was investigated in 25 patients. Eighteen patients underwent intra-abdominal vascular surgery and 7 undersent lower-extremity orthopedic procedures. At the completion of surgery, tantalum was insufflated into both lungs of each patient to outline a representative sample of airways from the trachea to the small bronchi. Tantalum clearance was evaluated from serial radiographs obtained immediately after insufflation, at approximately 6, 18, 26, and 48 hours later, and thereafter whenever appropriate. In the 7 orthopedic patients, clearance of tantalum was progressive and usually complete within 48 hours. Atelectasis did not occur in this group. In 14 of the 18 patients who had abdominal surgery, mucociliary clearance was markedly abnormal in that tantalum was retained for up to 6 days. Pooling of tantalum-labeled mucus occurred in dependent bronchi in 16 of these 18 patients. Pooling preceded and always accompanied radiographically visible atelectasis. Lobar atelectasis occurred in 6 patients and segmental atelectasis in 8. Tantalum-labeled mucus moved peripherally in atelectatic lobes or segments and was retained in these bronchi until re-expansion took place. Thus, impaired ciliary function and mucous transport are associated with and implicated in postoperative pulmonary atelectasis

Radiographic evaluation of endotracheal tube position
Goodman, L R; Conrardy, P A; Laing, F; Singer, M M
A malpositioned endotracheal tube is a potential hazard to the intubated patient. Ideally, the tube tip should be 5+/-2 cm from the carina when the head and neck are in neutral position. In 92 of 100 patients studied, the carina overlay T5, T6, or T7 on portable radiographs. Therefore, even when the carina is not visible, it can be assumed that a tube tip positioned at the level of T3 or T4 is safe. The degree of neck flexion or extension at the time of radiography may be determined by evaluating the position of the mandible relative to the vertebral bodies
