Background: Limited studies are available for assessing the optimal pillow height for sniffing position to obtain the best glottic view during laryngoscopy and intubation in the Indian population. Aims: This study was designed to evaluate laryngoscopic view and intubation conditions in sniffing position using three different pillow heights (without a pillow, 4 cm, and 7 cm) during direct laryngoscopy. Settings and Design: This prospective analytical study was done in a tertiary care teaching institute. Materials and Methods: In 60 patients, direct laryngoscopy was performed in the sniffing position first without a pillow (0 cm), followed by a 4-cm pillow, and then a 7-cm pillow to assess the glottic view after administration of anesthesia. The laryngoscopic views were graded using the percentage of glottic opening (POGO) score and Cormack and Lehane (CL) grade. The pillow with the best laryngoscopic view was subsequently used to intubate the patient. Intubation difficulty was assessed by the Intubation Difficulty Score (IDS). The patient was followed up for 24 h postoperatively to evaluate postoperative complications due to intubation. Statistical Analysis: The categorical data were expressed in frequency and percentages and analyzed using the Chi-square test. Results: With a 4-cm pillow, there are a lower CL grade and a higher POGO score compared to views without a pillow and a 7-cm pillow which was statistically significant. There is a significantly lesser IDS score with a 4-cm pillow. Conclusions: The sniffing position with a 4-cm pillow provides a better laryngoscopic view and improved intubation condition than without a pillow and a 7-cm pillow in the study population.
