Background: This study aimed to get optimal sniffing position for successful intubation rate and measuring intubation time. The classical rationale for the sniffing position is that the alignment of the mandibular axis, pharyngeal axis, and laryngeal axis is facilitated, permitting successful direct laryngoscopy. Patients and Methods: A total of 100 patients without any anticipated difficult airway were enrolled after informed consent is given. After induction of anesthesia, patients were randomly divided into two groups. In Group PB, a deflated pressure infusion bag was put under the nape of the neck and occiput. The anesthetist performed laryngoscopy with the left hand while inflating the bag with the right hand up to the best glottic view without external pressure is achieved. The height of the bag was measured. In Group PI, 10-cm fixed-height noncompressible pillow was placed behind the head up to the shoulder. The best glottic view of the entire glottis without external pressure was noticed. Grading of glottic opening grade, SPO2, intubation time, and intubation trials were also noted. Results: Failure to intubate was noted in one patient in Group PB and two in Group PI. Intubations successful in 45 (90%) patients in Group PB as compared to 38 (76%) patients in Group PI (P < 0.05). Laryngoscopic view in Group PB was superior to that with Group PI (P < 0.05), with mean pressure bag height of 4.86 cm. Conclusion: The use of pressure infusion bag for adjustable-pillow height provides more success in intubation condition by head elevated position than the fixed height of 10 cm.
