Brief Summary

Supraglottic airway devices are important tools for airway management. Supraglottic airway devices have been introduced into brief surgical interventions because they are less invasive than intubation and safer than mask to maintain the patency of airway after induction of anesthesia. They are inserted via the oral route and can be used in emergency conditions when tracheal intubation and mask anesthesia are challenging. Air Q intubating airway and Ambu Aura intubating laryngeal mask are two Supraglottic airway devices that are widely used. Aim of the work is to compare Air-Q intubating laryngeal airway versus Ambu-Aura intubating laryngeal mask regarding sealing pressure and Fiberoptic intubation in class II obese patients.

Study Arms (2)

Air-Q intubating laryngeal airway mask

EXPERIMENTAL

Where Air-Q intubating laryngeal airway will be used for ventilation \& intubation through fiberoptic bronchoscope. After complete muscle relaxation a suitable sized (according to the patient's weight and BMI) Air-Q will be lubricated inserted and the ventilator circuit will be connected to the device to ventilate the patient. The ventilator will be set with tidal volume 4-6 ml/kg at a respiratory rate 12-15 breath/minute to keep normocapnia (ETCO2=30-35 mmHg). Vitals (HR, ABP and O2 saturation) and ET CO2were recorded 5 minutes after device insertion. Then intubation using the fiberoptic bronchoscope will be started through the supraglottic device, laryngeal view grade will be recorded, success of endotracheal intubation through the device and time of intubation (time starting from disconnection of the circuit from the device to use the fiberoptic brochoscope for intubation till tube insertion in the trachea).

Device: Air-Q intubating laryngeal airway

Ambu-Aura intubating laryngeal mask

EXPERIMENTAL

Ambu-Aura intubating laryngeal mask will be used for ventilation \& intubation through fiberoptic bronchscope. After complete muscle relaxation a suitable sized (according to the patient's weight and BMI) Ambu-Aura laryngeal mask will be lubricated inserted and the ventilator circuit will be connected to the device to ventilate the patient. The ventilator will be set with tidal volume 4-6 ml/kg at a respiratory rate 12-15 breath/minute to keep normocapnia (ETCO2=30-35 mmHg). Vitals (HR, ABP and O2 saturation) and ET CO2 will be recorded 5 minutes after device insertion. Then intubation using the fiberoptic bronchoscope will be started through the supraglottic device, laryngeal view grade will be recorded, success of endotracheal intubation through the device and time of intubation (time starting from disconnection of the circuit from the device to use the fiberoptic brochoscope for intubation till tube insertion in the trachea).

Device: Ambu-Aura intubating laryngeal mask
