About this study
Official title: Retrospective Study of the Risk of Aspiration and Postoperative Pulmonary Problems in Patients Who Have Had a Difficult Intubation.
The investigator wants to investigate if there is an increased risk of postoperative pulmonary problems in patients who have had an intubation where there was need for more than a laryngoscope.
Read the detailed description
A difficult intubation is defined as an intubation in which more than a laryngoscope was needed.
Afterwards patient data retrieved from the Clinical Work Station: age, type of operation and time, date, type of anaesthesia, de tools needed for intubation, time needed for intubation and anaesthesia.
In the Clinical Work Station of the Hospital the investigator will search for the following data in these selected patients: preoperative comorbidities, home medication, type of postoperative pulmonary problems and the treatment that was given, time of hospital stay and which department the patient stayed.
Patients with a difficult intubation will be linked to a patient with a corresponding medical history and type of operation but without a difficult intubation. The investigator will look for the same parameters of these patients in the Clinical Work Station.
By means of an odds-ratio the relative risk of a pulmonary complication after a difficult intubation in connection with an easy intubation with different variables can be calculated.

Questions about this trial
What is this clinical trial studying?
An observational study of Aspiration and Pneumonia, run by Universitair Ziekenhuis Brussel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Relative risk for postoperative pulmonary incidents (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2025; AzTrials last refreshed its copy on 6 Nov 2026.
