Algorithm for Emergency Management of Complicated STEMI

STEMI = ST-elevation myocardial; IV = intravenous; SL = sublingual; SBP = systolic blood pressure; BP = blood pressure; ACE = angiotensin converting enzyme

Algorithm of the cause of Hypokalaemia

A history of vomiting, diarrhoea, or use of medications such as diuretics can be helpful in determining the cause of hypokalaemia. However, in some cases, the cause of hypokalaemia is not readily apparent. In these cases, measurements of BP and urinary potassium excretion, and assessment of acid-base balance are often helpful.

Serum potassium concentrations:
There is no strict correlation between the serum potassium concentration and total body potassium stores. In chronic hypokalaemia, a potassium deficit of 200 to 400 mmol (200 to 400 mEq) is required to lower the serum potassium concentration by 1 mmol/L (1 mEq/L). These estimates are good provided there is no concurrent acid-base abnormality (e.g., for diabetic ketoacidosis or severe non-ketotic hyperglycaemia).

In diabetic ketoacidosis patients may have a normal or even elevated serum potassium concentration at presentation, despite having a marked potassium deficit due to urinary and GI losses.

Spurious hypokalaemia can occur when blood with a high WBC count is left at room temperature due to extraction of potassium by the WBCs. It is therefore important to consider repeating the test for confirmation.

Assessment of Head injuries in children

Perform a primary survey and ensure that the child’s airway, cervical spine, breathing and circulation are secure.

Rapidly assess the child’s mental state using the AVPU scale. Use firm supraorbital pressure as the painful stimulus.

* A Alert
* V Responds to voice
* P Responds to pain
----> Purposefully
----> Non-purposefully :

•  Withdrawal/flexor response
•  Extensor response

* U Unresponsive
Assess pupil size, equality and reactivity and look for other focal neurological signs.

Perform a secondary survey looking specifically at:

* Neck and cervical spine – deformity, tenderness, muscle spasm
* Head – scalp bruising, lacerations, swelling, tenderness, bruising behind the ear (Battles sign)
* Eyes – pupil size, equality and reactivity, fundoscopy
* Ears – blood behind the ear drum, CSF leak
* Nose – deformity, swelling, bleeding, CSF leak
* Mouth –dental trauma, soft tissue injuries
* Facial fractures
* Motor function – examine limbs for presence of reflexes and any lateralising weakness
* Perform a formal Glasgow Coma Score
* Consider the possibility of non-accidental injury during secondary survey especially in infants with head injury.
* Other injuries (see major trauma guidelines)

Ambulation Algorithm

FOOTNOTES:
1. Non-weight bearing: Patient is unable to bear weight through both lower extremities or weight-bearing through both lower extremities is contraindicated.

2. Partial weight bearing: This will include situations where the patient may be allowed: a) Limited weight bearing on one lower extremity and full weight bearing on the other extremity; b) Partial weight bearing through both lower extremities.

3. Safety risks may include: decreased cognition; decreased ability to cooperate/ combativeness; medical stability.

4. Factors that contribute to low safety risk: a) Lack of combativeness; b) Ability to follow commands; c) Medical stability; d) Experience with the assistive device.

5. Factors that contribute to high safety risk: a) Combativeness; b) Lack of ability to follow commands; c) Medical instability; d) Lack of experience with
the assistive device, e) neurological deficits.
