Abstract

Objective: To determine the frequency of difficult intubation in obese patients with neck circumference to
thyromental distance ratio (NC/TM) ≥5.0.
Study Design: Cross sectional study.
Place and Duration of Study: Department of Anaesthesia, Forward Treatment Centre, Kel (Azad Kashmir) and
Combined Military Hospital (CMH) Malir. Six months, from Jun 2015 to Nov 2015.
Material and Methods: A total of 94 patients between the ages of 18 and 50 years with body mass index (BMI)
≥27.5 kg/m2 and NC/TM ≥5.0 who received general anesthesia requiring tracheal intubation for elective surgery
(Orthopaedic, General Sugery, Urology & Gynaecology) were included in the study. Patients were induced
general anaesthesia and orotracheal intubation was done by anaesthetist with at least 1 year experience. Number
of intubation attempts were recorded in each patient. More than 3 attempts were considered difficult intubation.
Results: Eighty two (87.2%) out of 94 obese patients with BMI ≥27.5 kg/m2 and NC/TM ≥5 had difficult
intubation.
Conclusion: The NC/TM ≥5 was found good predictor for difficult intubation in obese patients.
