The comparison of the angle deviation of the nose line to the mentom and mallampati test in making prediction of the difficult airway problem before anesthesia

Abstract

A high percentage of important and dangerous events in anesthesia occur due to airway problems and proper airway management is always one of the important and key points during anesthesia. Airway control in critically ill patients is one of the most stressful situations for primary care physicians and even for anesthesiologists. The aim of this study was comparing the angle deviation of the nose line to the mentom and mallampati test in making prediction of the difficult airway problem before anesthesia Methods and materials: In this passing study, all information was extracted from patients' records. The modified Mallampati test was performed for all individuals by anesthesiologists and the data were recorded in specific forms. Based on laryngeal observation, patients were classified into 4 groups. Then, all data related to individuals including type of surgery, age, sex, weight, height, BMI and face angle were recorded. Patients with a Cormack and Lehane grade, who could score I or II, were considered easy intubation, and those with a Cormack and Lehane grade, grade III or IV, were considered difficult intubation. Results: A total of 85 patients from 17 to 67 years with a mean age of 12.89 ± 37.64 were studied. Examination of the relationship between laryngoscopic stiffness and Mallampati score showed that there is a statistically significant relationship between these two variables (P = 0.001). Examination of the relationship between laryngoscopic stiffness and the mean angle of deviation of the nasal line to the mentum showed that there is a statistically significant relationship between these two variables (P = 0.01). The degree of mallampathy is 85% predictive of laryngoscopic severity. NMLD can also predict 66% of laryngoscopic severity.
