Objectives: The study was conducted to assess the effect of endotracheal tube cuff inflation and position of the head on the success of blind nasal intubation. Method: In a hospital based cross-sectional study, 52 ASA Iand II patients were included. After induction of general anaesthesia, blind nasotracheal (BNTI) intubation was tried with patients on spontaneous ventilation in following sequence of head position and state of endotracheal tube cuff – Head on bed+cuff deflated (HBCD); Head on bed+cuff inflated (HBCI); Head on pillow+cuff deflated (HPCD); Head on pillow+cuff inflated (HPCI). Once intubation was successful in any one of these positions, the remaining positions were not tried. If blind nasal intubation failed, laryngoscopy was done and patient intubated. Results: Out of 52 patients, 1 of the 4 positions was successful for blind nasotracheal intubation in 47 cases (90.38%). BNTI was successful in 3(6.38%), 17(34.69%), 1(3.13%), 25(83.87%) in HBCD, HBCI, HPCD and HPCI positions respectively. The remaining 5 cases (9.62%) required laryngoscopy for intubation. Success of BNTI was significantly more with the tracheal tube cuff inflated whether head was on table (z score 3.265, P=0.0015) or head was on pillow (z score 4.89, P=0.000006). BNTI was also more successful with the head on pillow as compared to head on bed (z score 2.73, p<0.006). Complications seen were sore throat in 22 patients, epistaxis in 1 patient and stidor after extubation in 1 patient. Conclusion: We conclude that endotracheal tube cuff inflation as well as raising the head on pillow is efficacious in aiding BNTI.
