Model Answer

1.     Current symptoms of cardiorespiratory or systemic illness ie sob, active wheeze, vital signs should all be normal
        No major background medical problems eg cystic fibrosis / congenital heart disease, severe asthma
        Normal ASA classification
        No previous anaesthetic complications
        No allergies to sedation medications or paralysing or induction agents
        Fasting state – should preferably be fasted for 4 hours from solids and liquids, but may vary depending on urgency of the         procedure.
        Examination of CVS resp and neurol systems should be normal.

2.     Previous difficult airway
          Mobility of neck – eg rheumatoid arthritis or downs syndrome
           Mallampatti score
            Micrognathia
            Obesity – predicts short neck, anterior larynx
            Obstruction / foreign body / stridor
            Neck abnormalities
            Evidence of previous laryngeal abnormality or surgery

3.     Oxygen Saturation
        Carbon Dioxide EtCO2 - continuous
        HR
        BP
        LOC – GA vs deep vs dissociative vs moderate

4.     Vital signs normal
        Ambulating
        No nausea or vomiting
        Analgesia controlled
        Knowledge Required:
        Anaesthetic risk assessment
        Predictive scores for a difficult airway
        Procedural sedation protocols
        Safe discharge criteria / Disposition
