Combined Ultrasound and Upper Lip Bite Test Assessment of Difficult Laryngoscopy in Obese Patients
Sponsor: Cairo University
Summary
The aim of this observational study is to evaluate the accuracy of the HMDR combined with the ULBT as a predictor of difficult laryngoscopy in obese patients undergoing elective surgery under general anesthesia, regarding: * Correlation of HMDR-ULBT values with Cormack-Lehane grades during laryngoscopy. * Comparison of HMDR-ULBT with standard HMDR in predicting difficult laryngoscopy.
Official title: Ultrasound-Measured Hyomental Distance Ratio Combined With the Upper Lip Bite Test as a Predictor of Difficult Laryngoscopy in Obese Patients: A Prospective Observational Study
