In an emergency, if there is no Broselow tape, what is the formula for estimating a child's weight from their age?
Weight = (age + 4) x 2
IVLine
In a rural emergency, what is the formula for estimating a child's ETT size from their age?
ETT = age / 4 + 4
IVLine
In a paediatric anaphylaxis, what is the dose of adrenaline?
Adrenaline 0.01 ml/kg, using a 1mL syringe to draw it up straight from the vial that usually contains 1mg in 1 mL (1:1000).
e.g. 10kg child = 0.1 mL.
40kg child = 0.4 mL
IVLine
In a paediatric arrest, what is the formula for manual defibrillator joules?
Defibrillation = 4 joules / kg
IVLine
What are the SHAVED conditions that require rapid treatment in a deteriorating patient?
Sugar
Haemorrhage / hypovolaemia
Adrenaline
VF/VT
Epilepsy / seizures
Drugs / toxins
IVLine
Where should you insert an intraosseous needle?
Proximal tibia: Anteromedial surface, 2-3 cm below the tibial tuberosity
Distal tibia: Proximal to the medial malleolus
Distal femur: Midline, 2-3 cm above the external condyle
IVLine
If an AED is available immediately, when should the first shock be given? a) immediately b) after 30 sec CPR c) after 2 min CPR
Immediately. Defibrillation should be performed as soon as possible. 2 min cycles of resus only start AFTER this.
IVLine
In a paediatric emergency, why is a surgical airway contraindicated? What is the alternative?
Children's airways are anatomically different shapes and vital structures could be damaged by a scalpel cricothyroidotomy. The alternative is a needle cricothyrodotomy and jet insufflation (you can oxygenate but not ventilate through this).
IVLine
In airway management, when should head tilt not be done?
If c-spine injury is suspected (do jaw thrust and manual in-line stabilisation) or in an infant (neutral head position is required, consider a towel under shoulders as their head is proportionally large).
IVLine
In an emergency, what is ear-to-sternal-notch positioning?

Ear to sternal notch position optimises ventilation. This simple repositioning manoeuvre can make a large difference to the success of ventilating a patient in an emergency. There are many more useful tips for rural GPs on emDOCs.

Intraosseous infusion is painful. What can be done to reduce this pain?
Inject a small amount of lignocaine before commencing the infusion.

For each diagnosis that arises from your differentials, you can then consider the key signs, investigations and management. This list is by no means exhaustive, but here are a few assorted diagnoses to consider.

Foundation topics like anatomy, physiology and embryology are not the main focus of GP fellowship exams. The following are examples of topics that may be useful for quizzing any medical students you are supervising:
  • Australian spiders edit
  • Australian venomous snakes edit
  • AVPU edit
  • Femoral artery anatomy edit
  • GCS edit
  • Reversible causes of arrest: 4 Hs and 4 Ts edit
  • Shockable arrest rhythms edit
  • Types of shock edit
Medical students may be more focused on learning basic definitions, aetiology and pathophysiology of specific diagnoses, but registrars need to focus more on clinical problem solving. For each common presenting problem, consider what would be the red flag features, the most common differentials, as well as the most dangerous and most often missed (see Murtagh for more information on this model). For each diagnosis that arises from your differentials, you can then consider the key signs, investigations and management.
Medicine is nebulous with many conditions that arise infrequently in General Practice. These topics are not the main focus of college exams but nonetheless might occasionally appear - just as they can appear in your consultation room on a Friday afternoon. Other topics are so controversial that they are very difficult to examine. Here are some examples of topics that should not be the main focus of your study.
