Brief summary
Ventilation, as well as intubation of a morbidly obese patient, is challenging and require special preparations and skilful hands, in this study laryngeal mask airway insertion is used as a bridge for intubation to facilitate ventilation as give enough time to anaesthetics and muscle relaxants to work on.
Detailed description
The ordinary pathway of intubating a morbidly obese patient for sleeve gastrectomy is bordered by the risk of difficult ventilation and intubation with the subsequent events of hypoxia and hypoventilation. When the patient is easy ventilated, it gives some sort of confidence and pleasure for the anaesthetist that the way of intubation will not be so hard. One problem here is the difficulty of ventilating a morbidly obese patient, in this study the investigators used laryngeal mask airway as a bridge before inserting the endotracheal tube

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to intubation TTI | During the action of intubation after induction of anaesthesia | The time starts with insertion of glidescop and ends at its withdrawal |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| View of the glottis | During the action of intubation after induction of anaesthesia | Based on the percentage of glottic opening (POGO) score as well as Cormack and Lehane's (C&L) classification |
| Number of attempts required for intubation, | During the action of intubation after induction of anaesthesia | How many times the anaesthetist needs to try to succeed in insertion of the endotracheal tube |
| Anaesthetist's satisfaction score | During the action of intubation after induction of anaesthesia | On a scale rang from 0 representing totally dissatisfied to 10 representing fully satisfied |
| Intubation difficulty score (IDS) | During the action of intubation after induction of anaesthesia | Intubation difficulty score (IDS) is the sum of seven variables, each presents 1 point, score 0 represents easy intubation, score 1 to 5 represents moderate difficulty and score more than 5 was considered difficult intubation. |
| Need for external pressure during intubation | During the action of intubation after induction of anaesthesia | to direct the larynx downward to facilitate endotracheal intubation |
