Q

How does alcohol withdrawal present?

A

Day 1: anxiety, palpitations, GI upset, sweating and tremor
12hours = visual tactile (little people and insects on skin) hallucinations and normal mental stus

Day 2: 36hrs = short, generalised tonic-clonic seizures

Day 3 48 to 72hrs can be delirium tremens (fatal) -> delirium, severe tremor, fever and high BP and HR

Q

Alcohol withdrawal DDx of delirium tremens (confusion)

A

Acute liver failure so Ammonia, albumin, bilirubin, blood factors

Ammonia -> encephalopathy
Albumin -> Ascites + peripheral oedema
Bilirubin -> jaundice
Blood factors -> bruising

Q

What is anaphylaxis?

A

Life-threatening, systemic, hypersensitivity reaction characterised by airway +/- breathing +/- circulation problems. Usually associated with skin/mucosal changes

17
Q

What are common triggers for anaphylaxis?

A

0-4YO

1) food e.g. nuts
2) Drugs/chemics e.g. penicillin, NSAIDs, latex, contrast
3) Toxins e.g. beewasp, venom

18
Q

Rf for anaphylaxis?

A

Hx of atopy e.g. hayfever or asthma

19
Q

What pathophysiological cause of anaphylaxis symptoms?

A

Mast cell and basophil degranulation = increased cap permeability, bronchospasm and reduced vascular tone

20
Q

Anaphylaxis presentation?

A
Airway = angioedema of throat, swelling and stridor
Breathing = SOB, increased RR decreased O2
Circulation = SHOCK -> low bp, high hr, decreased consciousness

Skin mucousal = urticaria and angioedema, flushing

SENSE OF IMPENDING DOOM

21
Q

Management for anaphylaxis?

A

1) HELP
2) Remove trigger
3) Lie flat and raise legs
4) IM adrenaline 0.5mg 1:1000
5) airway, breathing, circulation
6) IV chlorphenamine + IV hydrocortisone

Further investigation = serum tryptase and plasma histamine

22
Q

What follow up for anaphlaxis?

A

Refer to allergy or immunology e.g. RAST specifiv IgE testing
Provide epipen and education re anaphylaxis
Medic alert bracelet

23
Q

RFs for overdose?

A

<10 usually accidental

>10 usually deliberate and associated with alcohol abuse

24
Q

What to use in management?

A

TOXBASE
NPIS helpline
Consider activated charcoal if <4hours
Consider gastric lavage

25
Q

How much for aspiring OD?

A

Usually 300mg tablets so OD >150mg/kg, sever if >500mg/kg

26
Q

Early aspirin OD presentation?

A

Tinnitus, deafnes, dizziness, hyperpnoea, N+V, diarrhoea + hyperthermia, sweating
Per-spiring-g

27
Q

Late Aspiring OD presentation?

A

Low bp + Heart block, pulmonary oedema and low GCS + seizire

28
Q

Lab findings for Aspirin OD?

A

Early respiratory alkalosis

Late high anion gap metabolic acidosis

29
Q

Aspirin OD management?

A

urine alkalinisation with IV sodium bicard
Dialysis
Supportive

30
Q

Paracetamol OD Amount?

A

Usually 500mg so OD 150mg/KG, 12g can be fatal

31
Q

Pathophysiology of paracetamol OD?

A

Normally metabolised by CYP450 in liver to NAPQi, conjucated to glutathione and excreted. Therefore, run out of glutathionine and toxic NAPQi accumulates and hepatocyte necrosis

32
Q

Paracetamol OD presentation?

A

Often asymptomatic
<24hrs : mild N+V, lethargy
24-72 hrs: RUQ, vomiting and hepatomgealy
>72hrs : acute liver failure

33
Q

Management of paracetamol OD?

A

IV N-acetyl cysteine if below treatment line

Liver transplant if above on paracetamol normogram

34
Q

Presentation of Opiate OD?

A

CNS depressants = resp depression, bradycardia, hypotension, pinpoint pupils,.
Late severe = low GCS and coma

35
Q

Management of Opiate OD?

A

IV Naloxone
