Relationship Between Higher Operating Tables And Laryngeal Views For Endotracheal Intubation

Abstract

Background: Research on the impact of operating table height on laryngeal vision is crucial in order to reduce anesthesiologist pain during ventilation, one-attempt laryngoscopy and intubation. Therefore, the main goal of this study is to ascertain how various operating table heights affect laryngeal vision during dorsal endotracheal insertion. 

Methods: This prospective observational study was conducted in the department of anesthesia  , among 200 cases undergoing surgery with general anesthesia. Patients aged 18-60 years from both genders and ASA class I and II were included in the study. Cases with BMI > 35 kg/m2, anatomical abnormalities of head and neck and pregnant females were excluded. A total of 200 cases with 100 in group U (umbilicus level) and 100 in group N (Nipple level) were included.

Results: On comparing the clinical profile of study participants, age, gender, BMI categories and ASA classes among the cases in group U and group N were similar with no statistical significance. On assessing the association between CL grades and discomfort score between group U and group N, there was a significant association noted.

Conclusion: We came to the conclusion that easier mask ventilation is made possible by lower operating table levels, while higher levels—ideally at the nipple level—are better for tracheal intubation and laryngoscopy.
