About this study

Official title: Supreme Laryngeal Mask Use in Urgent Caesarean Section

The Supreme Laryngeal Mask Airway (SLMA) is a single use supraglottic device that provides a good seal for positive pressure ventilation and good first attempt insertion rate of 98% in low risk patients undergoing elective Caesarean section. It has a double aperture design that facilitates the introduction of an orogastric tube to aspirate gastric contents.

The primary study hypothesis is the first attempt insertion success rate of SLMA use in urgent Caesarean section.

Read the detailed description

Investigators propose a prospective cohort study to study the first attempt insertion success rate of supreme LMA in general anaesthesia for urgent caesarean section.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. First attempt insertion success rate

    An attempt is defined as insertion and withdrawal of the device from the patient's airway

    Measured: 1 hour

Secondary outcomes (8)
  1. Time to effective airway placement

    Interval from when the device was picked up until appearance of the first end-tidal carbon dioxide waveform

    Measured: 1 hour

  2. Aspiration

    Signs of aspiration as evidenced by perioperative hypoxaemia, wheezing or crepitations upon auscultation of lungs or postoperative dyspnoea with chest x ray signs of aspiration

    Measured: 1 hour

  3. blood on SLMA on removal

    inspection for presence of blood upon removal of SLMA

    Measured: 1 hour

  4. Sore throat

    Sore throat present in recovery room

    Measured: 1 hour

  5. Regurgitation

    Gastric contents identified in the mouth with pH less than 4

    Measured: 1 hour

  6. Seal pressure

    Recorded by closing the adjustable pressure limiting valve and insufflating the closed breathing system with 3L/min fresh gas flow. The peak circuit airway pressure achieved will be recorded.

    Measured: 1 hour

  7. Gastric aspirate

    Volume of gastric aspirate using gastric tube and pH of gastric aspirate using litmus paper

    Measured: 1 hour

  8. Neonatal outcomes

    Neonatal birthweight. APGAR score. Umbilical venous cord pH

    Measured: 1 hour

Questions about this trial

What is this clinical trial studying?

A study testing Supreme Laryngeal Mask Airway in people with Airway Morbidity, run by QuanZhou Women and Children's Hospital at 1 site in China.

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 6 inclusion and 3 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 3 Aug 2020. 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 China. 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?

First attempt insertion success rate (time frame: 1 hour). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02026882, which also lists 3 linked publications.

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 3 Aug 2020.
