Evaluation of the pediatric bonfils fiberscope for elective endotracheal intubation

Difficult airway management in children is a particular challenge for anesthesiologists and pediatricians. This study was designed to evaluate the performance of the recently developed pediatric versions of the Bonfils fiberscope for elective endotracheal intubation during routine surgical procedures. After approval by the institutional review board and written informed consent, 55 children (age 6 +/- 4 years) scheduled for elective minor surgical procedures were enrolled. Nineteen children received atropine before the intubation attempt, while in the remaining 36 children, no antisialogogue was used. For endotracheal tubes up to 3.5 mm internal diameter, a fiberscope with outer diameter (OD) 2 mm, and for larger endotracheal tubes, a fiberscope OD 3.5 mm was used. Time to intubation and failure rate were obtained. In the 36 children without and the 19 children with atropine pretreatment, the success rate for tracheal intubation on the first attempt was 69%/78% (25/15 patients). 4/3 patients and 2/0 patients were intubated after two and three attempts, respectively, and in 5/1 patients (14%/5%) intubation failed even after three attempts. Time to intubation was median 58/60 s, 25th-75th percentile 35-100/32-110 s, and range 14-377/18-360 s. In both groups, failed intubations were because of the secretions contaminating the optic aperture. High failure rate and increased intubation times suggest that the pediatric Bonfils fiberscope has significant drawbacks when used for intubation of normal pediatric airways.

Use of the Bonfils Fiberscope in Patients with Simulated Difficult Airways

The Bonfils fiberscope is a rigid, fiber-optic intubating stylet that is used to introduce an endotracheal tube through the vocal cords under

Subcutaneous Cervical and Facial Emphysema with the Use of the Bonfils Fiberscope and High-Flow Oxygen Insufflation

We present a case in which use of the Bonfils retromolar intubation fiberscope resulted in cervical and facial subcutaneous emphysema. The patient was a 75-yr-old woman with Mallampati Grade I airway. The Bonfils retromolar intubation fiberscope was used for teaching purposes. Flow on the oxygen port of the fiberscope was set at 10 L/min. Immediately after insertion of the scope, her whole face and cervical skin showed severe subcutaneous emphysema. The patient was intubated conventionally and the emphysema resolved within 24 h. Subcutaneous emphysema after air insufflation is known from dental procedures with air entering through holes in the teeth. In our case, the oxygen insufflation was sufficient to create emphysema, probably through tiny mucosal lesions.

Anesthetic Management of a Patient with Noonan Syndrome: A case report

Noonan syndrome is featured by short stature, mental retardation, facial dysmorphia, webbed neck, and heart defects. The phenotype has some similarities with Turner syndrome, but the karyotype is normal and males can be affected. We used Bonfils fiberscope for intubation because we suspected the difficult airway. We report the experience of anesthetic management for osteotomy of calcaneonavicular coalition in a patient with Noonan syndrome.
