Difficult Airway Prediction in Paediatric Anaesthesia

Study Overview
=================
Brief Summary
-----------------
The incidence of difficult airway in paediatric population is up-to date not well described. Difficult airway is connected with significant airway-related morbidity and mortality. The majority of difficult airway in paediatric patients should be predictable. The aim of the study is to evaluate the incidence of difficult airway in paediatric patients scheduled for surgery under general anaesthesia and to test the predictability of the set of prediction tests to reveal the patients with high risk of difficult airway.

Detailed Description
-----------------
At the preanaesthetic visit the paediatric patients will be examined for difficult airway. The Mallampati score, interincisor garp, cervical spine mobility, upper lip bite test and thyromental distance will be measured. The distances will be measured in centimeters and the width of the distal part of the third finger will be measured to obtain the distance according to the patients fingers. The airway management plan will be defined and the incidence of the difficult airway (difficult face mask ventilation - two hand, two operators, desaturation, difficult intubation - Cormack-Leehane 3-4, intubation on 3 and more attempts, difficult laryngeal mask insertion and the incidence of cannot intubate cannot ventilate scenario will be evaluated. The predictability of the test for difficult airway prediction (Cormack-Leehane 3-4, cannot-intubate - cannot ventilate scenario, difficult mask ventilation) will be statistically analyzed.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of difficult airway in paediatric patients under general anaesthesia | The incidence of the difficult airway will be evaluated by the anaesthesiologist in the operating room. Difficult airway will be considered as difficult face mask ventilation, difficult intubation (Cormack-Leehane 3 and 4, intubation at 3 and over 3rd attempt), difficult laryngeal mask insertion (more than 2 attempts) and the presence of the cannot intubate - cannot ventilate scenario. | during anaesthesia induction | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Predictability of difficult airway | At the preanaesthetic examination a set of difficult airway prediction tests will be performed and the predictability of difficult airway will be evaluated by the statistical analysis | during anaesthesia induction |
