Interventions

Group 1: Control: without ravussin cannula as awake FOI under local anaesthesia (LA) and light analgesia (target RASS 0 to -1). Group 2: Intervention: with Ravussin cannula and FOI in deeper Analgose

Age
18 Years to No maximum

Inclusion criteria

Inclusion criteria: 1. elective surgery under general anaesthesia with expected difficult airway 2. indication for fibreoptic intubation

Exclusion criteria

Exclusion criteria: 1. pregnant patients 2. placement in an institution by judicial or administrative order exists. 3. participation in another prospective clinical intervention study within the last 30 days and during participation in this study 4. intolerance to lidocaine 5. BMI > 35 kg/m² 6. anatomical changes that make the placement of a Ravussin cannula impossible (e.g. tumour in the area of the cricothryoideum ligament, struma nodosa in the puncture area)

Design outcomes

Primary

MeasureTime frame
SpO2 below 92% during fiberoptic intubation (FOI)

Secondary

MeasureTime frame
- Vital signs (SpO2, etCO2, heart rate and blood pressure) during induction. - Ravussin-Cannula (RK), FOI and total procedure (duration in seconds/minutes) - Occurrence of hypoxia (SpO2 < 92%) in the total collective (frequency) - Complications (haemodynamic instability, puncture failure, intubation failure, haemorrhage, emphysema) - Secondary RK in control group in case of critical hypoxia - Patient satisfaction (questionnaire) - Respiratory complications in the recovery room or postoperative ward
