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
