NCT04498598

Brief Summary

The proposed A/Z modification of a supraglottic airway (SGA) incorporates an opening in the SGA body that enables access to the endotracheal tube (ETT) through the body of the SGA without the need of using an exchange catheter, thus enabling an ETT to move in the body of the SGA and convert a supraglottic to endotracheal ventilation. In its original form an adaptor made from same material currently used in the endotracheal tubes can make ventilation through the proposed airway device possible in exactly the same manner of a conventional SGA currently used. This adapter also known as the R-piece can be replaced with an ETT. The modification also allows placement of SGA over an existing ETT to convert and endotracheal (ET) to supraglottic (SG) mode of ventilation without the need to use an exchange catheter.

Outcome Measures

Primary Outcomes (1)

  • Test effect of A/Z modification of supraglottic airway device on rate of successful oxygenation and ventilation before beginning a full clinical trial

    An alteration and structural modification in the supraglottic airway device can improve safety of airway exchange in patient needing general anesthesia, this proof of concept should show if the modification has any affect on oxygenation and ventilation.

    During and immediately after the intervention

Secondary Outcomes (2)

  • Rate of successful exchange from supraglottic to endotracheal ventilation using A/Z modified SGA

    During and immediately after intervention

  • Rate of successful exchange from endotracheal to supraglottic ventilation using A/Z modified SGA

    During and immediately after intervention

Study Arms (1)

A/Z Airway

EXPERIMENTAL

Patients under general anesthesia for surgical procedures who need airway management for ventilation.

Device: A/Z Supraglottic airway

Interventions

Patient receive supraglottic airway for general anesthesia which can be converted to endotracheal ventilation reversibly

A/Z Airway
