[Discussion on security of fiber nasopharyngeal laryngoscope for children].

OBJECTIVE

To study the factors of complications and the incidence rates after the examination of fiber nasopharyngeal laryngoscope.

METHOD: To observe the complications appeared within 24 hours during and after fiber nasopharyngeal laryngoscope examination for 5000 children.

RESULT: Of 5000 cases, 305 cases (6.10%) occurred transient complications during and after the operation. The incidence of complications in different age groups (0-1, >1-3, >3-7, >7-16) were 9.83%, 6.14%, 3.15%, 1.69% respectively. It was significantly lower in older age groups compared with younger ones. The commonest complication was mucous membrane bleeding during the operation, which often occurred in infants and reduced by increasing age. Cough and cough deterioration often occurred after the operation and shortness of breath appeared in infants only. The differences were statistically significant.

CONCLUSION

Pediatric fiber nasopharyngeal laryngoscope examination is safe and reliable and most of the complications were minor. Infants and children with laryngeal cartilage softening is high-risk factors for complications.
