Q

What are the 3 main categories of distributive shock?

A
  • septic (infection causes release of cytokines + histamines -> vasodilation)
  • anaphlyactic (histamine release)

Q

What are the signs of hypoperfusion of tissues (caused by hypotension)?

A
  • altered mental health
  • mottled/ clammy skin
  • oliguria (low urine output)
  • tachycardia (compensation)
  • elevated lactate
22
Q

Who is at risk of septic shock?

A

Those with…

  • hypoxia
  • hypotension
  • delirium
  • tachycardia
23
Q

Describe the spectrum of sepsis.

A
  1. SIRS
  2. Sepsis
  3. Severe sepsis
  4. Septic shock
24
Q

What is 1) SIRS?

A

Systemic Inflammatory Response Syndrome

25
Q

How do you diagnose someone with SIRS?

A

They need to have ≥ 2 of these symptoms:

  • high temperature (>38 or <36)
  • high HR (>90bpm)
  • abnormal WBC count
26
Q

How is sepsis diagnosed?

A
  • SIRS criteria is met

- evidence of infection (blood cultures)

27
Q

How is severe sepsis diagnosed?

A
  • Sepsis with evidence of end organ hypoperfusion/ dysfunction (check lactate + urine output)
28
Q

How is septic shock diagnosed?

A

Severe sepsis with hypotension despite fluid resuscitation

29
Q

What is the sepsis 6?

A 
x3 TAKE
- blood cultures
- lactate in ABG
- urine output
x3 GIVE
- O2 -> keep sats ≥94%
- IV Abx within an hour
- Give fluid challenge + monitor BP
30
Q

How is lactate a sign of sepsis?

A

it is a sign of hypoperfusion (the cells are not getting sufficient O2 so have to resort to anaerobic respiration

31
Q

What tests can be ordered to investigate possible sepsis?

A
  • Biochemistry (Blood test)

- Blood culture

32
Q

What can the blood test pick up?

A
  • ⬆️ CRP (acute marker of inflammation)
  • ⬆️ Creatinine (sign of AKI)
  • ⬆️ Lactate
  • ⬆️ WCC
33
Q

What are the pre-renal causes of AKI?

A

dehydration

34
Q

What are the renal causes of AKI?

A
  • toxins

- glomerulosclerosis

35
Q

What are the post-renal causes of AKI?

A
  • prostrate enlargement

- kidney stones

36
Q

What does the NEWS2 score used for and what does it assess?

A

It is used for monitoring and escalating. It measures…

  • O2 sats
  • Temperature
  • BP
  • RR
  • Pulse
  • ACVPU scale
37
Q

Name the abdominopelvic regions.

A

right hypochondriac, right lumbar, right illiac, epigastric, umbilical, hypogastric (or pubic), left hypochondriac, left lumbar, and left illiac divisions

38
Q

What is a diverticulum?

A

A small pouch that pushes out through the weak spots in the outer layer of the wall of the intestines (usually large).

39
Q

Who is at risk of developing diverticula?

A
  • old people

- people with poor diet

40
Q

What primarily causes diverticula and how?

A

Insufficient fibre in diet

  1. If you don’t eat enough fibre, stools tend to be drier and more difficult to move along the gut.
  2. The muscles have go work harder to move the stools and the high pressure that develops can push the inner lining of the gut through to form a diverticulum.
41
Q

What is diverticulosis?

A

It means that diverticula are present, but do not cause any symptoms or problems.

42
Q

What is diverticular disease?

A

It is the condition where the diverticula cause intermittent, lower abdominal pain or bloating -> there is no inflammation.

43
Q

What are the symptoms of diverticular disease?

A
  • Bloating
  • Lower abdominal pain (left lower quadrant)
  • Bloating
  • Diarrhoea/ constipation
  • PR bleeding
44
Q

What conditions present similarly to diverticular disease?

A
  • IBS (though this is more common in young people)

- Early bowel cancer

45
Q

How can diverticular disease be treated?

A
  • High fibre diet
  • Drink water
  • Take paracetamol
46
Q

What is diverticulitis?

A

It is the condition where the ≥ 1 diverticula get inflamed and infected.

47
Q

What can cause diverticulitis?

A

If faeces get trapped in a diverticulum as the bacteria in the faeces can cause infection.

48
Q

What are the symptoms of diverticulitis?

A
  • Constant pain in the abdomen
  • Pyrexia
  • Constipation/ diarrhoea
  • Blood in stool
  • Nausea/ vomiting
49
Q

What are the complications of diverticulitis?

A
  • Bowel obstruction
  • Abscess formation (collection of pus)
  • Fistula formation (a channel may form to nearby organs)
  • Perforation of the wall of the bowel -> peritonitis
50
Q

How can diverticulitis be treated?

A
  • Abx for mild symptoms
  • IV (if vomiting)
  • Surgery (for complications)
