简要总结
PURPOSE :Sonographic assessment of airway parameters to predict difficult laryngoscopy and intubation – a comparison with clinical airway predictors in adult patients undergoing elective surgery.
DESIGN: A Prospective, observational study
PARTICIPANT :patients undergoing elective surgeries with endotracheal intubation under general anesthesia
INTERVENTION:Parameters observed during preoperative assessment:Demographic parameters like Age, Sex, Weight, Body Mass Index (BMI), ASA status and comorbidities will be noted.
Clinical Airway assessment-Mouth opening, Neck movements, Mallampatti grade, thyromental distance, mentohyoid distance, jaw protrusion and Neck circumference at the level of larynx.
Sonographic Airway assessment: Patient will be sitting with head in the neutral position, looking straight with the mouth closed and the tongue on the floor of the mouth without any movement.
With the transducer placed at the submandibular area in the sagittal and transverse planes. Sonographer will be blinded to clinical airway predictors and Cormack-Lehane grades.Parameters to be seen are Skin to
epiglottis distance- measured at the level of the thyrohyoid membrane (For difficulty intubation) and Condyle to tragus distance (For prediction of difficult laryngoscopy).
Patients will be then taken inside the operating room and general anaesthesia with muscle relaxant will be administered as per institutional protocol and standard of care. Laryngoscope guided intubation will be
performed by anaesthesiologists who will also record Cormack- Lehane grade and calculate intubation difficulty scale score.
MAIN OUTCOME MEASURES:Improved accuracy in assessing difficult airway
