new presentation of T1DM

19
Q

what investigations should be done for DKA?

A

bedside blood glucose and ketones

12 lead ECG

20
Q

what pH is classed as acidosis ?

A

<7.3

21
Q

what pH is classed as severe DKA?

A

<7.1

22
Q

what are children at a higher risk of developing compared to adults following DKA?

A

cerebral oedema

23
Q

what fluid bolus should DKA shock children receive ?

A

fluid bolus of 10ml/kg 0.9% sodium chloride.

24
Q

how do you calculate fluid deficit for a child?

A

body weight x %fluid deficit x 10

25
Q

what are the fluid maintenance for children with DKA
<10kg
10-40kg
>40kg

A

If the child weighs less than 10kg, give 2ml/kg/hour

If the child weighs between 10 and 40 kg, give 1ml/kg/hour

If they weigh more than 40kg, give a fixed volume of 40ml/hour

26
Q

what dose of IV insulin should be given for DKA?

A

0.05 – 0.1 units/kg/hour of a soluble insulin

27
Q

what monitoring should be done during K replacement ?

A

ECG

28
Q

when can IV insulin be changed to subcutaneous insulin can then be started and IV insulin stopped one hour later?

A

blood ketones are less than 1mmol/litre or pH is normal.

29
Q

what are some complications of DKA?

A

cerebral oedema
hypokalaemia
aspiration pneumonia
hypoglycaemia

30
Q

what is the leading cause of death of children presenting with DKA?

A

cerebral oedema

31
Q

what signs and symptoms can be suggestive of cerebral oedema?

A

Headache, confusion, irritability, increasing drowsiness, hypertension with bradycardia and focal neurological signs such as cranial nerve palsies and papilloedema

32
Q

what could cause decreased fluid intake or increased fluid loss in children?

A

structural malformation
discomfort
respiratory distress
neglect

D/V
excessive sweating
polyuria
burns

33
Q

what are some red flags of dehydration ?

A
Appears unwell or deteriorating
Altered responsiveness
Sunken eyes
Reduced skin turgor

34
Q

what fluid bolus should be used in shocked children?

A

35
Q

in what circumstances should children be given IV fluid?

A

50ml/kg for second 10kg bodyweight

20ml/kg for every kg above 20kg bodyweight

37
Q

what is the initial bolus for children with DKA?

A
