Removal of Tracheobronchial Foreign Bodies via Suspension Laryngoscope and Hopkins Telescope in Infants

Abstract

Objectives:

Tracheobronchial foreign body aspiration is a life-threatening accident in infants, and is still a formidable clinical emergency to both otorhinolaryngologists and anesthesiologists. In this study, we attempted to assess the safety and ease of tracheobronchial foreign body removal in infants via suspension laryngoscopy and Hopkins telescopy under general anesthesia with endotracheal intubation.

Methods:

The retrospective clinical study from 2006 to 2010 included 50 infants with foreign body aspiration, of whom 35 underwent suspension laryngoscopy and Hopkins telescopy and the other 15 underwent rigid bronchoscopy. All of the procedures were under general anesthesia with endotracheal intubation.

Results:

All of the patients underwent temporary extubation. The foreign body was successfully removed in 46 cases and was not found in the other 4 cases. The mean operation time in the rigid bronchoscopy group was 13.20 ± 9.01 minutes, and that in the Hopkins telescopy group was 5.79 ± 3.54 minutes. The oxygen saturation level was below 90% in 17 cases, of which 7 were in the rigid bronchoscopy group and 10 were in the Hopkins telescopy group. The vital signs, including the partial pressure of carbon dioxide in expiratory gas and the heart rate, were stable in all cases.

Conclusions:

Foreign body removal in infants via suspension laryngoscopy and Hopkins telescopy under general anesthesia with endotracheal intubation should be promoted, since it is relatively safe and easy for both anesthesiologists and otorhinolaryngologists to perform and has a remarkable success rate.
