Abstract
Introduction: Difficult tracheal intubation is a common source of mortality and morbidity in many setting include: Operation, Intensive Care Unit (ICU), and Emergency ward. The incidence reported of difficult tracheal intubation is 0.1%–13% and reaches 14% in the obese population. The objective of the study was to investigate and compare the utility of Body Mass Index (BMI) as indicator of difficult tracheal intubations in patients who underwent for elective surgery under general anesthesia.
Aim: To find out the relationship between BMI and difficult tracheal intubation among patients who went for elective surgery under general anesthesia.
Background: The study was done by using the intubation difficulty scale (IDS), Mallampati score, and Wilson score, to confirm that obese patients are more difficult intubation than lean patients.
Material and methods: Prospective observational descriptive design was used in this study to patients who underwent for elective surgery under general anesthesia. The sample was 100 patients. The study done in Jenin governmental hospital; the following information was obtained from participants for analysis: gender, age, height, weight, BMI, past medical history, past surgical history .Assessment Mallampati score, IDS, Wilson score, and the American Society of Anesthesiologists classification assigned by the anesthesiologist and senior doctors provider performing the endotracheal intubation.
Result: The total number of IDS was (81%) of participants who underwent elective surgery under general anesthesia were categorized as slightly difficult intubation according to IDS score. And 2% of participants were classified as moderate to major degree of intubation difficulty. 17% of participants were labeled as easy degree of intubation difficulty. And there is correlation between the Mallampati class and Wilson score with BMI p < 0.001 and p =0.008 respectively.
Conclusion and recommendation: In conclusion, data showed that BMI is a reliable indicator for difficult tracheal intubation in patients who underwent elective surgery under general anesthesia. Mallampati classification and Wilson score is a strong predictor of difficult tracheal intubation in patients who underwent elective surgery under general anesthesia in correlated to their BMI, age and gender are not predictor for difficult intubation according to IDS scale. Future prospective studies should aim to include controlled preoperative assessments and defined concept of difficult tracheal intubation
