About this study
Official title: A Descriptive Study Comparing a Horizontal Ultrasound Technique With a Palpation Technique for Localising the Cricothyroid Membrane in an Obstetric Population.
The investigators will be comparing a traditional palpation (feeling) technique with an ultrasound technique for finding a specific part of the neck.
Read the detailed description
This study compares a traditional palpation (feeling) technique with an ultrasound technique for finding a specific part of the neck. Finding this part of the neck is important for anesthesiologists in emergencies and can sometimes be difficult. We would like to determine if using ultrasound is easier and more reliable than examining the neck by hand. Newer methods using ultrasound have not been studied in detail in the pregnant population.
This study aims to describe a simple technique for identifying the cricothyroid membrane. The secondary aim is to determine how ultrasound compares to palpation in pregnant women at term.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ultrasoundOther
subjects' neck will be scanned using ultrasound
| Study group | Role | What they receive |
|---|---|---|

Questions about this trial
What is this clinical trial studying?
A study testing ultrasound in people with Airway Identification, run by University of British Columbia at 1 site in Canada.

Who may be eligible to take part?
The sponsor lists 2 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 2 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
Airway localization (time frame: 10 minutes). 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 2 Apr 2015; AzTrials last refreshed its copy on 6 Nov 2026.
