Q

What is shock and the four causes of this?

A

Life threatening condition caused by the systemic failure of the circulatory system, causing inadequate perfusion of major organs

  • Hypovolemic
  • Obstructive – obstruction of blood flow to and from the heart
  • Cardiogenic – pump failure
  • Distributive
  • Septic

Q

What are three signs of compensated shock?

A

ALWAYS CONSIDER IF CHANGE IN MENTAL STATE

  • Tachycardia to increase cardiac output
  • Redistribution of blood flow to increase perfusion of more important organs at the expense of others (e.g. skin and kidneys)
  • Tachypnoea to reduce anaerobic respiration and reduce lactic acidosis formation
  • Reduced urine output
  • Increased cap refill

Q

What are some causes of hypovolaemic shock?

A
  • Dehydration e.g. diarrhoea, vomiting, burns, inadequate feeding in infants, or diuresis in DKA
  • Third spacing e.g sepsis and anaphylaxis, the release of inflammatory mediators increases the permeability of capillaries, leading to fluid in the capillaries moving to the interstitial space
  • Haemorrhage.

Q

What is the management for shock?

A
  • A to E
  • 20ml/kg bolus with saline. Get IO line if IV difficult
  • Blood products/inotropes if not responding to fluids e.g IV adrenaline ordopamine
  • Escalate to PICU
  • Treat underlying cause e.g sepsis 6

In children with suspected cardiogenic shock, be cautious with fluid resuscitation and start with 5ml/kg fluid boluses

Q

According to NICE what are some symptoms and signs of dehydration and shock?

A

Think about dry mouth/tongue and no tears

Reduced urine output

31
Q

What are some red flags for dehydration in children?

A
  • Appears unwell or deteriorating
  • Altered responsiveness
  • Sunken eyes
  • Reduced skin turgor
  • Tachycardia
  • Tachypnoea
32
Q

How is dehydration managed in children?

A
  • Start fluid chart
  • PO or IV fluids
33
Q

How much PO fluid is given to correct dehydration?

A

Oral Rehydration Solution

50ml/kg + Maintenance Fluids over 4 hours

34
Q

Which dehydrated children need IV fluids?

A

20ml/kg 0.9% Sodium Chloride (10ml/kg if DKA) if shocked

  • Shock is suspected or confirmed
  • A child with red flag symptoms or signs
  • A child persistently vomits the oral rehydration solution
35
Q

If a child is in shock you give 20ml/kg bolus. If a child is not in shock, what amount of IV fluids should you give them?

A

Fluid Deficit + Maintenance

Weight (kg) x % replacement x 10. This is given over 48 hours

The % replacement (also known as % dehydration) should be assumed to be 10%, if dehydrated.

36
Q

What monitoring needs to be done when correcting dehydration in children?

A

MONITOR THROUGHOUT 48 HOURS OF CORRECTION

  • U+Es: to determine if need electrolytes added to fluids
  • Plaasma glucose

Significant ongoing losses through, for example, vomiting or diarrhoea should be documented on the patient’s fluid balance chart and replaced in addition to fluid deficit correction

37
Q

How can you work out percentage dehydration in children?

A

Percentage weight loss

If no previous weight loss available and clinically dehydrated use 10%

38
Q

What is the definition of sepsis and septic shock?

A

Dysregulated immune response to an infection that leads to life threatening organ damage

When cardiovascular compromise this is shock

SIRS (systemic inflammatory response) in the presence of infection

39
Q

What is the pathophysiology of septic shock?

A

Causative pathogens recognised by macrophages, lymphocytes and mast cells. These cells release cytokines to activate immune system. This activation leads to release of NO which causes vasodilation

Cytokines can make endothelial lining of blood vessels more permeable so fluid leaks into interstitial fluids causing oedema and distributive shock

Coagulation system also activated causing fibrin deposition in circulation further compromising organ and tissue perfusion. Causes DIC

Blood lactate rises as a result of anaerobic respiration in the hypo-perfused tissues with an inadequate oxygen

40
Q

When should a child be screened for sepsis?

A

PEWS >3 ALWAYS SCREEN UNLESS OBVIOUS CAUSE

If they have infection e.g pneumonia, UTI, could be sepsis

41
Q

What children are at higher risk of sepsis?

A
  • Neonates to 3 months old
  • Immunocompromised e.g. diabetes, splenectomy, immunosuppressants, cancer
  • Recent surgery in the last six weeks
  • Breach of skin integrity (burns/cuts/skin infections)
  • Presence of an indwelling catheter or line
42
Q

What is the definition of SIRS?

A

Suspected infection plus Symptoms

43
Q

What are some symptoms and signs of sepsis in children?

  • Rash
  • Decreased urine output
  • Poor feeding or oral intake
  • Cool peripheries
  • Increased respiratory rate
  • Increased respiratory effort
  • Bradycardia or tachycardia
  • Floppy
  • Signs of dehydration (e.g. dry mucous membranes, decreased skin turgor, delayed capillary refill time)
44
Q

What are some red flags for sepsis?

A
  • If a child is not rousable, or does not stay awake when roused
  • Bradycardia or tachycardia for age
  • Bradypnoea or tachypnoea for age
  • Mottled skin
  • Peripheral or central cyanosis
  • Non-blanching rash
45
Q

What differentials should be considered for sepsis in children?

A
  • Kawasaki Disease (prolonged fever)
  • Simple infection (see if fever responds to antipyretics)
  • Anaphylaxis
  • DKA
  • Bronchiolitis
46
Q

NICE uses a traffic light system to determine risk of serious illness in under 5’s. What are some of the parameters that are looked at?

A

Remember anyone <3months with a temperature over 38 is sepsis until proven otherwise

  • Colour
  • Activity
  • Respiratory
  • Circulation and hydration
  • Other
47
Q

If sepsis is recognised how is this managed?

(use chart)

A
  • Oxygen if sats <94%
  • Obtain IV access (cannulation)
  • Blood tests: FBC, U&E, CRP, clotting screen, blood gas for lactate and glucose
  • Blood cultures
  • Urine dipstick and laboratory testing
  • Antibiotics within 1 hour of presentation
  • IV fluids: if the lactate is above 2 mmol/L or there is shock
  • Consider PICU referral
  • Consultant review within 14 hours
48
Q

What investigations are done during the sepsis 6 pathway?

A

Laboratory tests

  • FBC
  • CRP
  • Coagulation
  • Blood culture
  • U+Es
  • Blood gas for lactate and glucose
  • Urine dipstick and US
49
Q

What investigations are done after the sepsis 6 pathway to try and find the source of infection?

A

Imaging or invasive tests (done after sepsis 6 to locate source of infection)

  • CXR if suspect pneumonia is cause
  • Lumbar puncture (if under 3 months) if suspect meningitis
  • Abdominal US if suspect intrabdominal infection
  • Meningococcal PCR
50
Q

How is amber flag sepsis managed?

A
51
Q

What antibiotics are used in sepsis for the following groups of patients:

  • <1 month
  • 1 -3 months
  • >3 months
A

< 1month: Gentamicin, Amoxicillin, Cefotaxime

1-3 months: Amoxicillin and Ceftriaxone

>3 months: Ceftriaxone

52
Q

How long should antibiotics be continued for in sepsis?

A

5 – 7 days if a bacterial infection is suspected or confirmed

Alter antibiotic choice and duration once a source of infection is found and an organism is isolated

Consider stopping where there is a low suspicion of bacterial infection, the patient is well and blood cultures and two CRP results are negative at 48 hours

53
Q

What is the prognosis with sepsis in children?

A

Linked to speed of recognition and antibiotic administration

Bacterial meningitis: need to monitor for long-term developmental delay, and audiological testing. Limb ischaemia may lead to amputations

54
Q

If a child presents with a fever (temp >38) what questions do you need to ask?

A
  • Onset, duration, pattern of fever, and method of temp measurement
  • Associated symptoms suggesting an underlying cause of fever.

  • Any significant medical conditions, e.g immunosuppression
  • Any recent antipyretic drug and/or antibiotic use
  • The child’s immunization history, and any missed immunizations
  • Recent foreign travel
  • Recent contact with people with serious infectious diseases
  • Parental/carer health beliefs about fever and previous family experience of serious febrile illness (may increase parent/carer anxiety)
55
