Summary

Is there a difference in vocal cord visualization between the retromolar and conventional access?

Detailed description

Management of the difficult airway is still an essential part of modern anaesthesia. Up to now, there have bee no clinical investigations comparing the intubation method via the retromolar route (RM), with the conventional intubation route (CM). For the present clinical investigation, 100 patients undergoing elective surgery will be investigated in the General Hospital of Vienna when for the anaesthesia intubation is required. In both intubation methods (RM and CM) the anaesthesiologist will visually determine the Cormack \& Lehane score in a randomly assigned sequence with and without a BURP-manoeuvre (= backwards, upwards and rightwards pressure). Thereafter intubation is performed in all patients by the CM method and if intubation fails the RM technique will be used. Of course, as per usual, every intubation trial is interrupted by a 20 second 100%-oxygen-ventilation period to reach a pulse oximetry oxygen saturation of at least 97% SpO2. Thereafter, if intubation fails again every other intubation technique will be applied, as necessary and called for.

• Intubation

Interventions

Type	Name	Description
OTHER	Retromolar Vocal Cord Visualisation	For easier insertion of the laryngoscope the head of the patient will be turned to the left site. Thereafter the blade (Miller) will be inserted into the mouth and pushed carefully as far as possible laterally to receive a direct view of the vocal cords. Then the performing anesthesiologist determine the Cormack \& Lehane score without and thereafter with a BURP (backward upward rightward pressure) maneuver.
OTHER	Conventional Vocal Cord Visualisation	The head of the patient will be positioned as usual. After 2 minutes oxygen insufflation the laryngoscope will be inserted laterally to push the tongue to the left side in order to release the sight to the vocal cords. Thereafter the anesthesiologist determines the Cormack \& Lehane score without and thereafter with performance of the BURP (backward upward rightward pressure) maneuver.
