Abstract
Airway problems represent the most common cause of morbidity and mortality due to anesthesia. Tracheal intubation is still the gold standard for securing the airway. Stress response to laryngoscopy and intubation has always been concern especially for cardiac patients and patients with intracranial complications , stimulation of pharyngeal structures is thought to be the most important factor in producing pressor response and tachycardia during intubation. In addition to cardiovascular responses, laryngoscopy and tracheal intubation induce an arousal response on the EEG .
Air Q ILA is a new supraglottic device and fulfills the criteria of ideal supraglottic devices which are: ease of placement, reliable alignment of the glottis opening, ability to continuously oxygenate and ventilate, minimize disconnection time from the breath circuit
The aim of this study is to compare between two techniques of intubation through the air Q ILA in the haemodynamic response of intubation, arousal response, time, attempts of insertion of air Q ILA, time, attempts and success rate of endotracheal intubation.
Methods:
This study was conducted at Bani- Suef University Hospital, 100 patients were admitted for general anaesthesia and divided into two groups according to the technique of intubation through air Q ILA.
Group І: 50 patients for blind insertion of endotracheal tube through air Q ILA.
Group ІІ: 50 patients for endotracheal tube insertion through air Q ILA guided by flexible fiberoptic bronchoscope.
Results:
There was statistically significant lower BIS value in the fiberoptic group 1 minute after intubation than in blind group. Also, systolic and mean blood pressure were statistically significant lower in the fiberoptic group than blind group. There was no statistically significant difference between the two groups in the heart rate and diastolic blood pressure.
Time and attempts of insertion of air Q ILA were statistically significant lower in fiberoptic group than in blind group. There was statistically significant lower time of intubation and lower attempts in fiberoptic group than in blind group and success rate of intubation in the fiberoptic group was 100% compared to 76% in blind group. Intubation through air Q ILA had less incidence of complications in both techniques.
Conclusion:
The air Q LMA it is a good ventilatory device associated with no hemodynamic pressor response or arousal response nor desaturation when used for endotracheal intubation either blindly or fiberoptic guided. It is a an effective conduit for endotracheal intubation guided by flexible fiberoptic bronchoscope, further studies are recommended including larger number of patients and in patients with suspected difficult airway.
