چکیده

BACKGROUND Induction of anesthesia and tracheal intubation in small children with a difficult airway is a challenging task. We report the experience with a procedure based on sevoflurane inhalation via a nasopharyngeal airway inserted early during induction before airway obstruction occurs. A pediatric fiberscope is used to perform a nasotracheal intubation via the opposite nostril. METHODS All small children with suspected or known difficult airway needing tracheal intubation were scheduled for a fiberoptic intubation following the described protocol. RESULTS In 3 years, we performed 27 successful fiberoptic guided tracheal intubations in 19 children, median age 8.2 months (1.0-39.1 months) and median weight 7.6 kg (3.0-15.0 kg). The optimal depth for placement of the nasopharyngeal airway was found to be 8.0 cm (7.0-8.5 cm) from the nostril in the first year of life and 8.5 cm (8.0-10 cm) in the second year. Oxygenation was sufficient during the entire procedure in all cases except one child who had short-lasting laryngeal spasm caused by instillation of lidocaine during light anesthesia. The duration of fiberoptic intubation was significantly shorter when performed by an experienced anesthesiologist (55 s vs. 120 s), but there was no significant correlation between the duration of fiberoscopy and oxygen saturation during fiberoscopy or endtidal CO(2) after intubation. CONCLUSION The combination of nasopharyngeal airway and fiberoptic guided tracheal intubation seems to be a reliable and safe procedure for managing the difficult airway in small children.

Expected difficult airway in children.

PURPOSE OF REVIEW The expected difficult airway in children is a rare, but predictable entity, which can lead to life-threatening situations, when sufficient oxygenation and ventilation cannot be achieved. This review gives an overview on current techniques and recommendations on where, who, when, and how to treat children with expected difficult airway. RECENT FINDINGS The equipment for a st...

  Airway management is the most important duty of an anesthetist, so more attention should be paid on different educational approaches in tackling difficult airway. Having problems in airway control leads to terrible consequences such as hypoxia and aspiration. Intubation with fiberoptic is a useful method for a safe airway management.   When neck movement is not possible due to cervical spine ...

Awake video laryngoscope intubation: case report of a patient with a nasopharyngeal mass.

Difficult airway management remains central to anesthesia practice. Video laryngoscopes have been an adjunct to airway management since the early 2000s. They have been shown to improve visualization of the glottic opening and have become a useful aid in managing difficult airways. To date, the preferred method for difficult airway management remains awake fiberoptic intubation. The purpose of t...

Most cause of difficult intubation are anatomically disorders such as micrognathia, head and neck deformities, cervical spine disorders .Most of post-anesthetic harmful complications are due to airway management problems and hypoxemia. Therefore one of the most important points in the airway management is the appropriate selection of safe policy. In this study we introduce a 79 – years old man...
