Comparison of Sniffing Position and Head-Neck Position for Direct Laryngoscopy
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 4
Abstract
Background: Positioning of the patients head and neck for best visualization of glottis is the prime need before laryngoscopy and intubation. The study was conducted to compare traditional sniffing position with head elevation/neck flexion position to find out which position provides better laryngoscopy and intubation in patients undergoing elective surgery under general anaesthesia. Materials and Methods: One hundred patients were randomly allocated to two groups. In Group I (n=50), laryngoscopy was done in sniffing position, while in Group II (n=50), laryngoscopy was done in simple head extension with head flat on operating table. Glottic visualization was assessed by Cormack-Lehane grading and Intubation Difficulty Scale. Results: More patients in head extension group had better glottic visualization compared to those in sniffng position. There was statistically significant difference between the two groups as per Cormack and Lehane grading (p=0.04). The total Intubation Difficulty Scale score indicated that ease of tracheal intubation was significantly better (p=0.02) in Group II (head extension position) as compared to Group I (sniffing position). Conclusion: Simple head extension position is better than traditional sniffing position with regarding to ease of intubation as found by Intubation Difficulty Scale.
