Case Report: Double Visualization Intubation Strategy for Patients With Ankylosing Spondylitis.

Front Med (Lausanne) 2022 18;9:659624. Epub 2022 Mar 18.

Department of Anaesthesiology, The Second Affiliated Hospital, Fujian Medical University, Quanzhou, China.

Airway devices in paediatric anaesthesia.

Indian J Anaesth 2019 Sep;63(9):721-728

Department of Anaesthesiology and Critical Care, Institute of Post Graduate Medical Education and Research, Kolkata, West Bengal, India.

Airway devices were first used in children since 1940 and thereafter an increasingly large number of paediatric airway devices have come into our armamentarium. To control and protect the airway in children during anaesthesia, in intensive care unit or in emergency department either tracheal intubation is performed under direct or indirect visualization of vocal cords with the help of laryngoscopes or video-laryngoscopes respectively or it can be done blindly or by using special instruments such as fiberoptic laryngoscope, lighted stylet or Bullard laryngoscope to name a few. Airway also can be maintained with the help of Laryngeal mask airways, oropharyngeal and nasopharyngeal airways. Read More

A novel method to position an endotracheal tube at the correct depth using an infrared sensor stylet.

Can J Anaesth 2013 May 1;60(5):444-9. Epub 2013 Feb 1.

School of Electrical Engineering, University of Ulsan, Ulsan, South Korea.

Purpose: This study is a feasibility assessment to determine the ability of novice users to utilize an infrared (IR) sensor stylet as a guide to position the tip of the endotracheal tube (ETT) 40 mm proximal to the carina in the swine trachea.

Methods: We developed a stylet system using an IR sensor attached to the tip of a stylet to facilitate measuring the distance of the ETT from the carina. The indicator lamp of the IR sensor system turns on through calibration when the ETT tip arrives at a point 20 mm proximal to the carina. Read More

Reducing injury during video-assisted endotracheal intubation: the "smart stylet" concept.

Laryngoscope 2011 Nov 24;121(11):2391-3. Epub 2011 Aug 24.

Division of Laryngology, Department of Otolaryngology-Head and Neck Surgery, The University of Washington School of Medicine, Seattle, Washington 98195, USA.

Objectives: Video-assisted endoscopic intubation (VAEI) has gained wide use in anesthesiology when difficult intubation is encountered. Even when excellent visualization of the larynx is achieved with VAEI, successful intubation can be difficult and/or traumatic due to awkward angles and rigid stylets. Presented is a modification of standard VAEI procedure that allows for minimization of intubation trauma. Read More

Epiglottic prolapse induced by lighted stylet tracheal intubation.

J Anesth 2011 Apr 2;25(2):294-7. Epub 2011 Feb 2.

Department of Anesthesiology, Shizuoka Cancer Center, 1007 Shimonagakubo, Nagaizumi-cho, Suntoh-gun, Shizuoka 411-8777, Japan.

We report a case of epiglottic prolapse induced by lighted stylet tracheal intubation perceived by following upper gastrointestinal endoscopy. A 68-year-old male was to undergo endoscopic mucosal resection (EMR) under general anesthesia for a superficial orolarynx cancer spreading over the root of the tongue. Because the mucosal change was so minimal, intubation was performed with a lighted stylet instead of a direct laryngoscope, to prevent its metal blade spoiling the delicate endoscopic findings.

Klinik für Anästhesiologie, Intensivmedizin und Schmerztherapie, Klinikum der J W Goethe-Universität Frankfurt am Main.

Background: Previous studies have shown that video laryngoscopy enhances laryngeal view in patients with apparently normal and difficult airways. The utility of the novel, portable, battery-powered C-MAC video laryngoscope is as yet unproven. It was hypothesized that in routine patients undergoing ENT surgery, the rate of glottic views considered unsatisfactory, i. Read More

Placement of the Univent tube without fiberoptic bronchoscope assistance.

Anesth Analg 2010 Feb 21;110(2):508-14. Epub 2009 Nov 21.

Department of Anaesthesiology, West China Hospital, Sichuan University, State Key Laboratory of Biotherapy of Cancer, Chengdu, Sichuan, People's Republic of China.

Background: In this study, we evaluated the feasibility and accuracy of Univent tube (Fuji Systems, Tokyo, Japan) placement with the aid of auscultation (AUS) or as guided by a lighted stylet (LS) compared with placement guided by the fiberoptic bronchoscope (FOB) or the blind intubation technique as recommended by the manufacturer's guidelines.

Methods: Eighty ASA physical status I-II adult patients requiring single-lung ventilation for elective thoracic surgery were randomly allocated into 4 groups according to the method used for Univent tube positioning: manufacturer-recommended (MR) group (n = 20); FOB group (n = 20); AUS group (n = 20); and LS group (n = 20). Tracheal placement of the Univent tube was accomplished with direct rigid laryngoscopy after anesthetic induction and was positioned by the same anesthesiologist using 1 of the above-described methods.

Airway management in trauma.

Minerva Anestesiol 2009 May;75(5):307-11

Department of Anesthesiology and Resuscitation, Pitié-Salpétrière Hospital, Paris, France.

Maintenance of a patent and prevention of aspiration are essential for the management of the trauma patient, that requires experienced physicians in airway control techniques. Difficulties of the airway control in the trauma setting are increased by the vital failures, the risk of aspiration, the potential cervical spine injury, the combative patient, and the obvious risk of difficult tracheal intubation related to specific injury related to the trauma. Endotracheal intubation remains the gold standard in trauma patient airway management and should be performed via the oral route with a rapid sequence induction and a manual in-line stabilization maneuver, to decrease the risks previously mentioned.

A comparison of cervical spine motion during orotracheal intubation with the trachlight(r) or the flexible fiberoptic bronchoscope.

Anesth Analg 2009 May;108(5):1638-43

Departement of Anesthesiology, Centre Hospitalier de l'Université de Montréal, Hôpital Notre-Dame, Montreal, Canada.

Background: Tracheal intubation of an unstable cervical spine (c-spine) patient with the flexible fiberoptic bronchoscope (FOB) is thought to minimize c-spine movement but may be technically difficult in certain patients. Intubation using a luminous stylet, such as the Trachlight(R) (TL), also produces minimal motion of the c-spine and may be an interesting alternative technique for patients with an unstable c-spine. In this study, we compared the cervical motion caused by the TL and the FOB during intubation. Read More

A comparison of lighted stylet (Surch-Lite) and direct laryngoscopic intubation in patients with high Mallampati scores.

Anesth Analg 2009 Apr;108(4):1215-9

Department of Anesthesiology and Pain Medicine, School of Medicine, Konkuk University, Seoul, Korea.

Background: A lighted stylet is an effective alternative to a direct laryngoscope and has been reported to be particularly useful in patients with difficult airways. A high Mallampati class indicates poor visibility of the oropharyngeal structures. Because a lighted stylet does not require direct oropharyngeal visualization, we hypothesized that the lighted stylet would be easier to use than a direct laryngoscope in patients with a high Mallampati score.
