NCT02611141 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

No results posted yet for this study

Summary

Retromolar Intubation is a successful option for intubation in patients with an existing retromolar gap in the case that the conventional method fails.

Therefore the investigators want to test if the retromolar gap is essential for performing the retromolar intubation technique.

Conditions

  • Airway Management

Interventions

PROCEDURE

Retromolar laryngoscopy and scoring of the visualisation of the vocal cords according to Cormack & Lehane

To facilitate the insertion of the straight blade laryngoscope (Miller #4) the head of the patient will be turned to the left side. The blade will be inserted and then pushed laterally rightwards until the retromolar space will be finally reached. Thereafter the epiglottis will be lifted up in order to achieve the best direct view to the vocal cords and scored according to Cormack \& Lehane . This score will be assessed at least 2 minutes after muscle relaxation: 1. Once without a backward, upward, rightwards pressure maneuver (=BURB) and immediately thereafter (i.e. 5-10 seconds later): 2. If 100% visualization of the vocal cords is not possible a BURP maneuver will be performed and the scored again. Intubation will then be performed by the conventional method using a Macintosh blade #3. In the case that intubation with the conventional method is not successful the retromolar technique will be used.
