Eligibility
Sex/Gender
All
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Patients undergoing elective thoracic surgery and for what DLT-intubation for one-lung ventilation is required
Exclusion criteria
Exclusion criteria: - patients who did not consent to the study - pregnant patients - patients who have not reached the age of 18 years - patients with indications for so-called "rapid sequence induction" - patients who have a contraindication to one-lung ventilation - patients with severe cervical spine movement restriction, e.g. ankylosing spondylitis - patients who are not capable to consent
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint is time to achieve lungseparation | — |
Secondary
| Measure | Time frame |
|---|---|
| other endpoints are: - primary intubation success, documented by a case report form; - quality of pulmonary collapse during one-lung ventilation by the blinded surgeon at the end of the operation using a standardized 3-item questionnaire; - different process times during the anesthesia initiation phase: material preparation; intubation using DLT, SLT, placement EZ-Blocker; bronchoscopy time for placement control of DLT or SLT/EZ-Blocker the occurrence and extent of intubation damage. Intubation damage is documented immediately before the end of the respective surgery by video laryngoscope (supraglottic) and by bronchoscope (subglottic). On the first day postoperatively, a follow-up examination by means of a flexible endoscope (supraglottic) is also carried out with electronic image documentation. The evaluation is carried out in the further course by blinded study physicians. A patient survey is also carried out using a questionnaire derived from the validated QLQ-H & N35 questionnaire module for diseases of the head and neck area. | — |
