This manikin study aimed to compare the performance of disposable non-channeled and channeled blades of the King Vision\u2122 videolaryngoscope in simulated cervical spine injury. Fifty-eight anesthesiologists in training intubated the TruMan manikin with the neck immobilized using each blade in a randomized order. The primary outcome was the time needed for tracheal intubation, secondary aims included total success rate, the time required for visualization of the larynx, number of attempts, view of the vocal cords, and subjective assessment of both methods. Intubation time with the channeled blade was shorter, with a median time of 13 s (IQR 9\u201319) vs. 23 s (14.5\u201337.5), p &lt; 0.001, while times to visualization of the larynx were similar in both groups (p = 0.54). Success rates were similar in both groups, but intubation with the non-channeled blade required more attempts (1.52 vs. 1.05; p &lt; 0.001). The participants scored the intubation features of the channeled blade significantly higher, while visualization features were scored similarly in both groups. Both blades of the King Vision\u2122 videolaryngoscope are reliable intubation devices in a simulated cervical spine injury in a manikin model when inserted by non-experienced operators. The channeled blade allowed faster intubation of the trachea.<\/jats:p>","DOI":"10.3390\/diagnostics10030139","type":"journal-article","created":{"date-parts":[[2020,3,3]],"date-time":"2020-03-03T13:06:23Z","timestamp":1583240783000},"page":"139","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Video Laryngoscopic Intubation Using the King VisionTM Laryngoscope in a Simulated Cervical Spine Trauma: A Comparison Between Non-Channeled and Channeled Disposable Blades"],"prefix":"10.3390","volume":"10","author":[{"given":"Jiri","family":"Votruba","sequence":"first","affiliation":[{"name":"First Department of Tuberculosis and Respiratory Care, 1st Medical Faculty of the Charles University and General University Hospital, 128 00 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomas","family":"Brozek","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Medicine, 1st Medical Faculty of the Charles University and General University Hospital, 128 00 Prague, Czech Republic"},{"name":"Medical Faculty, Masaryk University, 625 00 Brno, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Blaha","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Medicine, 1st Medical Faculty of the Charles University and General University Hospital, 128 00 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomas","family":"Henlin","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Medicine, 1st Medical Faculty of the Charles University and University Military Hospital, 128 00 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomas","family":"Vymazal","sequence":"additional","affiliation":[{"name":"2 nd Medical Faculty of the Charles University and University Hospital Motol, 150 06 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Will","family":"Donaldson","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia, Antrim Area Hospital, Antrim BT41 2RL, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8119-5927","authenticated-orcid":false,"given":"Pavel","family":"Michalek","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Medicine, 1st Medical Faculty of the Charles University and General University Hospital, 128 00 Prague, Czech Republic"},{"name":"Department of Anaesthesia, Antrim Area Hospital, Antrim BT41 2RL, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"821302","DOI":"10.1155\/2015\/821302","article-title":"Impact of video laryngoscopy on advanced airway management by critical care transport paramedics and nurses using the CMAC pocket monitor","volume":"2015","author":"Boehringer","year":"2015","journal-title":"BioMed.
