AbstractWe present a rare case involving a broken suction catheter that became lodged in the tracheobronchial tree. An eight-month-old infant was scheduled for hernioplasty. Following intubation with a 4 French (Fr.) endotracheal tube, a 5 Fr. reused suction catheter was applied for suctioning a moderate amount of secretion. This catheter had been resterilized by ethylene oxide gas (EOG). Insertion of the catheter into the tube was not done smoothly, and we could not obtain any secretion. During the extraction of the suction catheter by force, the catheter broke. The distal fragment (20 cm length) seemed to have been lodged in the tracheobronchial tree. Prior to its removal by bronchoscopy, the endotracheal tube was extubated. Fortunately the remaining part of the catheter come out with the tube. Ten cm of the fractured catheter was included in the tube and 5 cm protruded from the tube. The catheter of smaller diameter is easy to be broken even by weaker force. After resterilization by EOG for once, there was no change in length and force at breaking point. Elongation of the broken catheter (85.5%) was less compared with the new sample (155%). At the breaking point, half of the cross section was very smooth and looked as if it had been cut by a razor, while the other half appeared to have been broken by pulling. The break may have started from the crack which had occurred at the insertion or resterilization. Therefore, we should restrict the reuse of small suction catheters, and should always utilize the catheter of the largest size possible.
