shikani optical stylet

Direct laryngoscopy and videolaryngoscopy are currently the dominant tools for endotracheal intubation. However, the video-assisted intubating stylet, a type of videolaryngoscopy, has been shown to offer some advantages over these tools, such as rapid intubation time, high first-attempt success rates, less airway stimulation, and high subjective satisfaction. On the other hand, this optical intubating technique also has some technical limitations that need to be addressed, including camera lens fogging, airway path disorientation, and obscured visibility due to secretions...

Direct laryngoscopy (DL) and videolaryngoscopy (VL) have been the most commonly used airway management modalities in the last several decades. Meanwhile, various optional airway tools (e.g., supraglottic devices, fiberoptic bronchoscopes) have been used for alternative rescue modalities when anticipated or unexpected difficulties in airway management has occurred. In recent decades, optical stylets and video-assisted intubating stylets have become another option for difficult airway scenarios. In contrast to other approaches, we have adopted the Shikani video-assisted intubating stylet technique (VS) for both routine and difficult airway management scenarios...

Among all the proposed predictors of difficult intubation defined by the intubation difficulty scale, head and neck movement (motility) stands out and plays as a crucial factor in determining the success rate and the degree of ease on endotracheal intubation. Aside from other airway tools (e.g., supraglottic airway devices), optical devices have been developed and applied for more than two decades and have shown their superiority to conventional direct laryngoscopes in many clinical scenarios and settings. Although awake/asleep flexible fiberoptic bronchoscopy is still the gold standard in patients with unstable cervical spines immobilized with a rigid cervical collar or a halo neck brace, videolaryngoscopy has been repeatedly demonstrated to be advantageous...

BACKGROUND: Although minimization of cervical spine motion by using a neck collar or manual in-line stabilization is recommended for urgent tracheal intubation (TI) in patients with known or suspected cervical spine injury (CSI), it may worsen glottic visualization. The overall performance of video-stylets during TI in patients with neck immobilization remains unclear. The current meta-analysis aimed at comparing the intubation outcomes of different video-stylets with those of conventional laryngoscopes in patients with cervical immobilization...

Diffuse idiopathic skeletal hyperostosis (DISH), asymptomatic in most cases, is a degenerative condition that commonly leads to anterior cervical osteophytes in most elderly patients. Clinically significant airway compression is rare. However, in some cases, the seemingly insignificant osteophytes could become a threat to airway management during intubation. Here we present a case of an 82-year-old man diagnosed as DISH and scheduled for cervical surgery. Radiographic imaging did not indicate the airway compromise...

BACKGROUND: To compare ultrasound-guided tracheal intubation (UGTI) versus Shikani optical stylet (SOS)-aided tracheal intubation in patients with anticipated normal airway. METHODS: Sixty patients aged 18-65 years old who presented for elective surgery under general anesthesia were recruited in this prospective randomized study. They were assigned into two equal groups, either an ultrasound-guided group (Group UG, n = 30) or an SOS-aided group (Group SOS, n = 30)...

BACKGROUND: We compared the effectiveness and safety of endotracheal intubation using the GlideScope (GS) video laryngoscope, CTrach laryngeal mask airway (LMA), or Shikani optical stylet rigid laryngoscope (SOS) during elective cervical surgery. METHODS: Forty-five patients undergoing elective cervical surgery were randomly and equally assigned to endotracheal intubation via GS, LMA, or SOS airway management. RESULTS: Endotracheal intubation was successfully completed in all patients...

BACKGROUND: Conventional intubation of the trachea and consequent prone positioning of anesthetized patients with cervical spine instability may result in secondary neurological injury. Historically, flexible fiberoptics used to be the chief choice for patients presenting with cervical spine instability surgery with difficult airway. Recently, the rigid optical stylets have shown promise in assisting difficult intubations. PURPOSE: The aim of the present study was to compare the efficacy of Shikani optical stylet (SOS) with the flexible fiberscope for awake intubation in patients with cervical spine instability...

BACKGROUND: Airway management is critical in patients with cervical spondylosis, a population with a high incidence of difficult airway. Intubation with Shikani Optical Stylet (SOS) has become increasingly popular in difficult airway. We compared the effects of intubation with SOS versus Macintosh laryngoscope (MLS) in patients undergoing surgery for cervical spondylosis. METHODS: A total of 270 patients scheduled for elective surgery for cervical spondylosis of spinal cord and nerve root type from August 2012 to January 2016 were enrolled and randomly allocated to the MLS or SOS group by random numbers...

OBJECTIVE: To compare the efficacy and safety of two different shaping methods for double-lumen endotracheal tube (DLT).DLT was shaped with the rod of a Shikani optical stylet (SOS) with the tracheal orifice aligned with the convex aspect of the distal curvature or the concave aspect of the distal curvature. METHODS: Patients scheduled for elective thoracic surgery and required intubation with a left-sided DLT were enrolled in this study. They were randomized into two groups...

INTRODUCTION: Scleroderma is a progressive fibrotic disorder of connective tissue which can present multiple anesthetic challenges to anesthetists, especially airway management. Awake intubation with fiberoptic bronchoscope is widely accepted and implemented for progressive systematic scleroderma patients. With the development and improvement of intubation devices these years, there is no report addressing other intubation methods for sclerotic patients. CASE DESCRIPTION: A 47 year-old, 42-kg man with 1-year history of localized scleroderma was scheduled for the operation of inner fixation after 6 days of his acetabular fracture...

The GlideScope(®) videolaryngoscope is widely utilised in the management of the difficult airway. However, complications such as mucosal injury, palatal and tonsillar perforations have been reported with its use. The Shikani optical stylet has shown promise in aiding difficult intubations. This randomised controlled trial evaluates the Shikani optical stylet as an alternative to the GlideScope videolaryngoscope in patients undergoing anaesthesia, with a simulated difficult airway. Sixty patients were randomised to undergo tracheal intubation with either the GlideScope videolaryngoscope (n = 30) or the Shikani optical stylet (n = 30)...

Large epiglottic cysts can block the glottis, leading to serious consequences. This condition presents a challenge in terms of airway management for anesthesiologists during induction of anesthesia. We report the use of a Shikani™ Seeing Optical Stylet combined with a Macintosh laryngoscope to aid tracheal intubation in seven patients with large epiglottic cysts. Use of this technique can avoid cyst rupture and allow smooth, safe intubation.
