Study summary

In this preoperative observational study, the effect of preoperative ultrasonographic measurements on the success of videolaryngoscopy in predicting difficult airways was investigated; furthermore, the aim was to determine new cut-off values that can predict difficult intubation in videolaryngoscope use. In our study, it was tested that the use of videolaryngoscope significantly increased the success of intubation in patients who were assessed as having difficult airways with upper airway ultrasound measurements.

Inclusion Criteria: * Patients aged 18 years and older * Patients undergoing elective surgery under general anesthesia requiring endotracheal intubation (ASA I-III) Exclusion Criteria: * Patients undergoing surgery under sedation or regional anesthesia * Patients not planned for endotracheal intubation * Patients with a history of difficult airway * Patients with an acute respiratory tract infection * Patients with congenital or acquired upper airway anomalies * Patients with facial or maxillofacial tumors or fractures * Patients with cervical spine fracture * Patients with a history of cervical or craniofacial radiotherapy * Patients with a tracheostomy * Pregnant patients * Patients who do not meet the required fasting period or who refuse to -participate in the study

Primary outcome measure(s)

  • Difficult videolaryngoscopic intubation — During videolaryngoscopy (periprocedural)
    Difficult videolaryngoscopic intubation will be assessed using the VIDIAC score, a scoring system specifically developed to quantify intubation difficulty during videolaryngoscopy.
