Comparison of CTrach, Intubating Laryngeal Mask Airway (ILMA) & I-gel for

Status Completed

Clinical Trial Summary

Various supraglottic airways may be used as a dedicated airway for insertion of intubating fibrescope and tracheal intubation in the patients with difficult to manage airways (Difficult Airway Society Guidelines).

The investigators aim to compare three different types of supraglottic device as a conduit for tracheal intubation - CTrach optical laryngeal mask, Intubating laryngeal mask airway and I-gel supraglottic airway. Null hypothesis for this study is that all three devices will perform without statistical difference in the means of success rate and time needed for their insertion and tracheal intubation.

Clinical Trial Description

Supraglottic airway devices such as I-LMa, Igel and LMA Ctrach are designed to create a "dedicated" airway which safely allows both spontaneous and controlled ventilation. The use of supraglottic airways can allow planned fibreoptic intubations in expected difficult cases and can provide an emergency airway in cases of unexpected difficult airway.

The ILMA (Intavent Orthofix Ltd.,Wokingham, UK) has been designed for either blind or fibrescope-guided tracheal intubation, in patients with expected and unexpected difficult airway. Since its development in 1997, it has been used for both blind and fibrescope-guided tracheal intubations in the patients with difficult airway. The ILMA is currently a 'gold standard' in supraglottic airways used for tracheal intubation.

The I-gel (Intersurgical Ltd., Wokingham, UK) is a newer dedicated airway device, which with its wide bore allows direct passage of a tracheal tube.

The CTrach (The Laryngeal Mask Company,Singapore) is a newer device for airway management. It has special optical fibres built-in inside its bowl and a liquid crystal display which allows views of the larynx while the endotracheal tube is being placed.

With reference to these supraglottic airway devices, only a small number of case reports detail tracheal intubation through an I-gel in patients with difficult airways. There have been manikin studies comparing ILMA and CTrach, and some descriptive studies on the use of CTrach in patients with predicted difficult airways- but no studies comparing the performance of these devices in clinical practice. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
