Comparison of the Vocal Cord Imaging Techniques After Thyroidectomy

Recurrent nerve palsy is a complication of thyroidectomy. Most surgeons want to visualize the vocal cords after tyroidectomy. The aim is to compare the direct laringoscopy, videolaringoscopy, fiberoptic laringoscopy and ultrasonography methods in terms of efficacy, duration and hemodynamic responses during the procedure.

About this study

The vocal cord will be visualised after the extubation with one of the following methods:

direct laringoscopy videolaringoscopy fiberoptic laringoscopy ultrasonography The of efficacy of the method (0= not able to visualize the vocal cords, 1= the vocal cords were visualized) duration of the procedure and hemodynamic responses (heart rate, mean arterial pressure) during the procedure will be compared between the groups.

Treatment and study plan

direct laringoscopy

Device

the vocal cords will be visualized after extubation with direct laringoscopy

Other names: direct laryngoscopy

fiberoptic nasal laringoscopy

Device

the vocal cords will be visualized after extubation with fiberoptic nasal laringoscopy

Other names: fiberoptic laryngoscopy

ultrasonograph

Device

the vocal cords will be visualized after extubation with fiberoptic ultrasonography

Other names: ultrsonography

Primary outcomes

  1. visualisation of the vocal cords

    Time frame: 1 min after extubation

    the vocal cords will be examined after extubation

  2. duration of the procedure

    Time frame: 10 min after extubation

    the duration of the vocal cord examination

  3. mean arterial pressure

    Time frame: 10 min after extubation

    the mean arterial pressure will be measured after extubation

  4. heart rate

    Time frame: 10 min after extubation

    the heart rate will be measured after extubation

  5. peripheal oxygen saturation

    Time frame: 10 min after extubation

    the peripheal oxygen saturation will be measured after extubation

Secondary outcomes

  1. hypertention

    Time frame: 5 minutes after the extubation

    mean arterial pressure >20% from baseline value

  2. tachycardia

    Time frame: 5 minutes after the extubation

    heart rate >20% from baseline value

  3. laceration

    Time frame: 5 minutes after the extubation

    blood detected on the blade/fiber optic scope, or macroscopic blood on the oral nasal mucosa

  4. teeht damage

    Time frame: 5 minutes after the extubation

    broken teeht
