Cuff inflation technique under King Vision video laryngoscope (KVVL) for nasotracheal intubation (NTI) in which cuff inflation of endotracheal tube (ETT) lifts ETT anteriorly, off the posterior pharyngeal wall to direct it towards glottis. Once tip of ETT is lifted and placed to vocal cords, cuff is deflated and tube is pushed gently into trachea through vocal cords then cuff is rein flatted to achieve intubation. The Aim was Effectiveness and safety of cuff inflation technique under king vision video laryngoscope over conventional method of Magill forceps for NTI. The Study Design and Methods was Sixty patients for 1 year of Inclusion Criteria- age 18 to 65 years, ASA grade 1 / 2, MPC 1 to 4 with mouth opening ≥2 cm undergoing elective surgeries. Exclusion Criteria- ASA 3/4, mouth opening <2cm. After informed consent and ethical committee approval, randomized by chit method to undergo NTI with either cuff inflation technique(Group C) under king vision video laryngoscopy (n=30) or Magill forceps(Group M) under conventional direct laryngoscopy (n=30). Study criteria- Stress response (HR, MBP), airway injuries and SPO2. In Statistical analysis Software’s- Excel, SPSS. Statistical tests - unpaired t test, Mann-Whitney test. P value<0.05 was considered significant. In Results were Demographical data was not significant (p>0.05). Group M showed rise in stress response as compared to group C (p=0.001). In group M, 5 patients recorded upper airway injury (p=0.794) and 1 patient with ETT cuff injury (p=0.981). No patient of either group showed hypoxia. The Conclusions was Cuff inflation technique reduced stress response and airway injuries due to Magill forceps. It can increase success rate of difficult NTI.
