Conditions

Anaesthesia Surgery Anaesthesia

Interventions

After extubation in the OR on admission to the PACU we will assess the position of the CAEC with a small flexible pharyngoscope of a diameter of only 2.8 mm (EF-BNI, Acutronic Medical Systems AG, Swit

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: All patients (aged greater than 18 years, either sex) entering the PACU with an oral or nasal airway exchange catheter will be included in the observational study. After they regained full consciousness, they will be asked whether the obtained data may be used for publication (informed consent).

Exclusion criteria

Exclusion criteria: 1. Refusal of post-intervention written informed consent 2. Aged less than 18 years

Design outcomes

Primary

Measure	Time frame
Dislocation rates of nasally placed airway exchange catheters versus dislocation rates of orally placed airway exchange catheters. Definition of dislocation is visualised extra-tracheal position (oesophageal, pharyngeal, enoral) of the CAEC (flexible nasopharyngosopy).	—

Secondary

Measure	Time frame
1. Demographic and morphometric data of the patients 2. Type of surgery 3. Duration of surgery and anesthesia 4. Blood loss during surgery 5. Indication for the airway exchange catheter 6. Duration of use of airway exchange catheter in minutes (mean, SD) 7. Number of events of ETCO2 measurement (indicating no gas flow) 8. Position of the CAEC at the time of an event of ETCO2 assessed by flexible nasopharyngoscopy 9. Sensitivity and specificity of ETCO2 measurement over CAEC 10. Patients tolerance against airway exchange catheter orally versus nasally (category 1, tolerated with any problem ¨C 10 not tolerated at all, therefore CAEC removed) 11. Indication for the removal of the airway exchange catheter 12. Duration of use of airway exchange catheter in minutes (mean, SD) 13. Re-intubation rate and time after extubation in minutes	—
