Interventions

Group 1: Insertion of a nasopharyngeal airway using the formula nose-tragus minus 10 mm

Sponsors

Universitätsmedizin Göttingen Klinik für Anästhesiologie
Lead Sponsor

Eligibility

Sex/Gender
All
Age
No minimum to 12 Years

Inclusion criteria

Inclusion criteria: 1. Children = 12 years of age, for whom an MRI of the head (cMRI) is performed for medical reasons and who require procedural sedation 2. To keep the airways clear, the insertion of a nasopharyngeal tube is necessary (decision of the anesthetist) 3. Existing declaration of consent after clarification and consent of the custodian parents / legal representatives

Exclusion criteria

Exclusion criteria: 1. Refusal to participate in the investigation 2. Known intolerance to the lubricant

Design outcomes

Primary

MeasureTime frame
Frequency (in percent) of the correctly placed nasopharyngeal tubes, if these were used according to the method of JOHNSSON et al. (2019) ("Nostril-tragus distance minus 10 mm")

Secondary

MeasureTime frame
1. Frequency (in percent) of the nasopharyngeal tubes correctly placed in the target area, if they had been introduced according to the rules distance nostril-tragus and distance nostril-maxillary angle, and comparison of these with the primary end point. 2. Identification of the optimal placement area of ??the tip of a nasopharyngeal temperature probe based on the MRI images defined as the shortest distance from the nasopharyngeal mucosa to the internal carotid artery
