The Shikani Seeing Stylet for difficult intubation in children: initial experience.
The Shikani Seeing Stylet is a recently introduced reusable intubating stylet, produced in adult and paediatric versions. It combines features of a fibreoptic bronchoscope and a lightwand. Inside a malleable stainless steel sheath, the Shikani Seeing Stylet has a fibreoptic cable leading to a distal light source and high-resolution lens. In use, the stylet is placed in the lumen of the selected endotracheal tube and the light source enables the stylet to be used as a lightwand, while the fibreoptic capability enables visualization of the laryngeal inlet. It is portable, relatively inexpensive and easy to maintain. This report describes the use of the stylet on eight occasions in seven children, all of whom were assessed preoperatively as being potentially difficult to intubate. Three had been difficult to intubate previously. All were anaesthetized using inhalational anaesthesia. Once an adequate depth of anaesthesia had been achieved, conventional direct laryngoscopy was performed and identified as Grade 3 in six of the patients and Grade 1 in one. Tracheal intubation was then attempted using the Shikani Seeing Stylet. On six of the eight occasions the attempt was made by different anaesthetists, none of whom had any prior clinical experience with the stylet. There were seven successful intubations and one failure in a patient who could not be intubated by any method. The Shikani Seeing Stylet seems a useful device for use in children with difficult airway problems, suspected cervical spine instability or limited mouth-opening.
