COMPARISON OF INTUBATION CHARACTERISTICSOF KING VISION VIDEO LARYNGOSCOPE VS C-MAC VIDEOLARYNGOSCOPE FOR NASOTRACHEALINTUBATION – A RANDOMISED CONTROLLED STUDY
Nasotrachealintubation is essential to provide surgical access in patients who areundergoing oral and maxillofacial surgeries. Nasotracheal intubation is morechallenging than orotracheal intubation due to the difficulty in advancing thetip of the endotracheal tube into the trachea.Video laryngoscopes aid invisualisation of the vocal cords without the need to align the oral, pharyngeal, and tracheal axes hence facilitating intubation. This study will be done tocompare C-MAC D-blade video laryngoscope to non-channelled King Vision videolaryngoscope for nasotracheal intubation. This study will include 86 ASA -1 and ASA-2 patients agedbetween 18 to 59 years undergoing maxillofacial or oral cavity surgeryrequiring nasotracheal intubation. Patients will be divided into 2 groups (43 each) randomly via computer generated sequence. A detailedpreanesthetic evaluation and all the relevant investigations will be done. On arrival in OT,standard ASA monitors will be attached and all patients will bepremedicated using 0.02 mg/kg midazolam, 0.2mg glycopyrrolate, 4mg ondansetron and2mcg/kg fentanyl intravenously. Allthe patients will be preoxygenated with 100% oxygen for 3 minutes. Standard induction will bewith Inj. Propofol 1.5-2mg/kg intravenously and Inj. Atracurium 0.5 mg/kgintravenously for muscle relaxation. Isoflurane will be used as theinhalational agent. Nasotracheal intubation will be performed withappropriately sized RAE(Ring-Adair-Elwin) endotracheal tube by an experienced anaesthesiologist.The primary outcome variable will be total intubation time calculated from the beginning of introduction ofthe RAE endotracheal tube in the nostril till the appearance of the first end‑tidalcarbon dioxide waveform(capnography). This willinclude time required for insertion of the ETT in each of three intubation steps(from nose into oropharynx(T1), from oropharynx into glottic inlet(T2), andfrom glottic inlet to observation of first capnographic trace(T3)). The timetaken will be noted by the Primary investigator using a stopwatch. Thesecondary outcomes will be comparingglottic view as percentageof glottis opening (POGO) score, modified nasal intubation difficulty score (NIDS) and complications related to NTI. Datacollected will be collected and will be tabulated for statisticalanalysis.
