Q

In this general condition, what factors would make you seek urgent attention for the patient?

(5)

A

This is AF on the ECG with a slow ventricular response

This ECG itself (slow V response) is not an indication for Emergency management. But the following are

  1. Rest angina (obviously)
  2. AF with rapid ventricular response
  3. Syncope or presyncope
  4. Clinical signs of heart failure
  5. Hypotension (haemodynamically unstable- which could happen with a slow response like this)

A

a. anorexia nervosa

b. 18

c SCOFF

d. Comorbid conditions

e. dehydration and metabolic disturbances

f. hypokalemia

48
Q

List at least 5 acute/emergency complications of the extensive list of complications from anorexia nervosa?

A

Acute Pancreatitis

Hypokalemia

Mallory-Weis tear (not always an emergency, but needs an emergency evaluation)

Arrhythmias

Suicide

49
Q

What is the most serious complication-syndrome that can arise when treating anorexia nervosa

A

Refeeding syndrome

During starvation, intracellular electrolytes become depleted from fat and protein catabolism.
Upon refeeding insulin secretion stimulates intracellular glucose and electrolyte uptake
leading to:
- Derangement of serum electrolytes (PO4, Mg, K)
- Vitamin deficiencies (Thiamine, B12, folate)
- Sodium and fluid retention
RFS can be life-threatening leading to complications such as cardiac failure, arrhythmia,
delirium and seizures.

50
Q

What are the four main drug induced dermatological emergencies ?

What is the management of them?

A

Steven Johnson Syndrome -SJS

Acute generalised exanthematic pustolosis (AGEP)

Toxic Epidermal Necrolysis (TEN)

Drug rash with eosinophilia and systemic symptoms (DRESS)

Management:
Transfer all suspected cases to the nearest emergency department, if suspecting TEN then arrange transfer to nearest hospital with a burns unit.

51
Q

What medications are implicated in causing this?

5As

A

This is Toxic Epidermal Necrolysis

Infact SJS and TEN are just variants of the same condition. Both include sheet like skin and mucosal loss.

Medications include
40% of the time Antibiotics: penicillins, cephalosporins, Co-trimoxazole

Anticonvulsants- lamotrigine, carbamazepine, phenytoin, phenobarbitone

Acetominophin; paracetamol and

Aspirin/NSAIDs

Allopurinol

52
Q

What is the clinical course in developing SJS/TEN?

A
  1. Before the rash there is usually a flu like prodrome (fever of 39+, conjunctivitis, rhinorhoea, cough, aches and pains)
  2. Rash Usually develops
    1 week after starting an antibiotic
    or 1-2 weeks after antiepileptic
    up to 1 month for other drugs

Then there is a rapid abrupt initiation of red skin rash, that for some reason doesn’t affect the scalp, soles or palms.

The lesions can be either
Macules
Purpura
Diffuse erythema
Targetoid (like in erythema multiforme)
Blisters

  1. The blisters then merge to form sheets of skin detachment, exposing red, oozing dermis. The Nikolsky sign is positive in areas of skin redness. This means that blisters and erosions appear when the skin is rubbed gently.
53
Q

What are 4 signs of sepsis or impending septic shock?

A

Tachypnoea (RR >22)
Hypotension (sBP < 90mmHg)
Altered consciousness
Blood Lactate >2mmol/L

54
Q

What are some life threatening features, when presented with a probably sepsis, indicated organ failure?

(5)

A

Poor peripheral perfusion
Mottled skin
Acute oligouria or raised serum creatinine
Raised billirubin
Low platelet count

55
Q

If hospital management is likely to be delayed by over an hour for sepsis, what antibiotic can you start?

A

ceftriaxone 2 g (child 1 month or older: 50 mg/kg up to 2 g) intravenously or intramuscularly given immediately

Use ceftriaxone even if there is mild-moderate reaction/hypersensitivity as treating sepsis is more important. However don’t make things worse if the person is known to have a SEVERE reaction to ceftriaxone.

56
Q

In the management of Sepsis in the ED, what steps are important to take?

A
  1. Measure blood lactate
  2. Obtain blood samples for culture
  3. Collect other samples as soon as possible, but not if it will delay treatment
  4. Administer broad spectrum antibiotics
  5. Begin rapid administration of IV fluids to manage hypotension or a blood lactate concentration more than 2 mmol/L
  6. Give a vasporessor IF NEEDED to maintain a MABP of 60mmHg
57
Q

What is the defining factor between non severe and severe hypoglycaemia and what is the treatment for non severe hypoglycemia?

A

If the patient is conscious and able to self administer oral treatment, it is non severe. If not able to treat themselves, even if not unconscious, then it is severe. This can be because patient has altered mental status because of the hypo or is generally incapable.

Non severe
Basically needs to eat/drink glucose.
< 5 years old AND under 25kg then 5grams of glucose
6 years and older or > 25kg then 10grams of glucose
for an adult then 15grams

It takes about 10-15 minutes for the glucose to arise. When it does rise to normal then longer acting carbohydrate should be consumed to prevent recurrence.

If BGL < 4.4 or if child is vomiting and cannot eat/drink then you can give a minidose of glucagon approx 10micrograms per year of age up to 150micrograms or 15 years old (then everyone gets 150micrograms)

58
Q

How do you treat severe hypoglycemia?

A

First
Glucagon
less than 25 kg: 0.5 mg subcutaneously or intramuscularly

25 kg or more: 1 mg subcutaneously or intramuscularly.

If the patient hadn’t eaten and has run out of glucose stores in the liver, then the patient will need IV glucose. In a 10% glucose solution over 20 minutes. Once glucose concentration >4mmol/L then can start a regular 5% glucose with NaCl 0.9% solution.

remember to warn of the implications for driving.

59
Q

omitting or forgetting glucose lowering medication
Starting medication or drugs that cause hyperglycemia
discontinuing antihyperglycemics

69
Q

What is the mainstay of treatment for Hyperosmolar Hyperglycemic Syndrome?

A

Fluid resuscitation

but this shouldn’t be done too aggressively
The aim of treatment should be to replace approximately 50% of estimated fluid loss within the first 12 hours and the remainder in the following 12 to 36 hours

Also need anticoagulants, and they are in a prothrombotic state

Potassium can be monitored, but isn’t as much of an issue. There is NO acidosis (DKA), so there shouldn’t be large intracellular shifts.

and how can it be treated?

A

This is an epidermal burn

Because the epidermis is damaged but intact, appears pink/red and painful.

Example: sunburn

management Cool showers or compress to manage warmth and pain. Ensure adequate hydration and moisturise skin.

If pain is significant use a hydrogel to soothe and provide analgesia. A secondary dressing is generally not needed.

One:
Unstable VT- DC cardioversion

Two:
Stable VT- can consider DC cardioversion at some stage,
other options medical

amiodarone intravenous infusion

or

lidocaine infusion

108
Q

What is paraphimosis and how can you attempt to treat it without surgical intervention?

A

It is when the foreskin is left in a retracted position and becomes oedematous, then tight and cannot be reduced over the glans

Steps
Give oral analgesia and reassurance
Wrap a firm compression bandage (ideally 1 inch, for example Coban, pictured) over the oedematous area, starting at penile tip
Leave bandage for 10-15 minutes (use a timer)
Remove bandage and attempt to reduce foreskin over the glans. If unsuccessful, repeat bandage for further 15 minutes and re-attempt
If manual reduction fails, obtain urgent surgical consult
