简要总结
To compare the accuracy of ultrasound-based airway assessment (skin to epiglottis distance) with Mallampati grading in predicting difficult endotracheal intubation in patients undergoing general anaesthesia. Additionally, to assess the role of ultrasound in measuring specific airway parameters such as tongue thickness, skin to epiglottis distance, thyromental distance, and hyomental distance (in neutral and extended neck positions), and to evaluate their predictive value for difficult laryngoscopy and intubation

入选标准
- •Age: Adult patients (18 years or older) scheduled for elective surgery under general anesthesia.
- •Airway Health: No history of significant airway anomalies such as obstructive sleep apnea, neck trauma, or tumors.
- •Normal Physical Examination: No obvious swelling, masses in the neck, or tracheal deviation.
- •Informed Consent: Willing to participate in the study and provide informed consent for ultrasound and clinical airway assessment.
- •ASA Classification: ASA I to III (healthy to moderately ill patients).
排除标准
- •Patients with anticipated difficult airways based on known risk factors (e.g., limited mouth opening, macroglossia).
- •Patients with significant congenital or acquired airway abnormalities (e.g., cleft lip/palate, tumors, tracheal stenosis).
- •Pregnant patients, due to anatomical changes that may alter airway management and ultrasound imaging.
- •Patients with altered mental status or who are unable to provide informed consent.
- •Patients with severe cardiovascular or respiratory diseases (e.g., ASA IV or V classification) that may complicate airway management.
- •Patients requiring emergency surgery where preoperative airway assessment is not feasible.
- •Patients with contraindications to ultrasound, such as skin infections or other local issues that may interfere with proper scanning.
- •Patients with cervical spine deformity.
