Q

Why does insulin treatment in DKA cause hypokalemia?

A

Serum potassium - high or normal, kidneys balance excreted with blood
Total body potassium low as not absorbed into cells
Therefore when treated with insulin not enough potassium in blood to be absorbed - hypokalemia

77
Q

Why do people need to wee before give potassium with fluids if above upper limit for potassium?

A

Confirm not becoming anuric

78
Q

How long after starting IV fluids wait to start insulin infusion?

A

1-2 hours

79
Q

What do rate give insulin infusion dose at?

A

0.05 or 0.1units/kg/hr

80
Q

What to do if child already on insulin?

A

For children and young people on continuous subcutaneous insulin infusion (CSII) pump
therapy, stop the pump when starting intravenous insulin.
* For children who are already on long-acting insulin, you may wish to continue this at the usual
dose and time throughout the DKA treatment, in addition to the IV insulin infusion, in order to
Therefore start an intravenous insulin infusion 1-2 hours after beginning
intravenous fluid therapy.
Use a soluble insulin infusion at a dosage between 0.05 and 0.1 units/kg/hour.
12
shorten length of stay after recovery from DKA.
* ISPAD guidelines suggest that starting an appropriate dose of long acting background insulin in
newly diagnosed patients alongside the intravenous infusion should be considered. The BSPED
working group felt this was an issue to be agreed locally and did not feel there was strong evidence
or consensus either way.

81
Q

When consider giving bicarbonate in DKA?

A

. Only consider
bicarbonate if there is life threatening hyperkalaemia or in severe acidosis with impaired myocardial
contractility

82
Q

When is there a risk of VTE in DKA?

A

Be aware that there is a significant risk of femoral vein thrombosis in young and very sick children with
DKA who have femoral lines inserted. Line should be in situ as short a time as possible. Thromboembolic
prophylaxis should be considered in young people >16 years (in line with NICE guidance), in young
women taking the combined oral contraceptive pill and sick patients with femoral lines, following
discussion with an Intensive Care Specialist.

83
Q

Medical reviews need to be done with DKA?

A

At 2 hours after starting treatment, and then at least every 4 hours, carry out and record the results of
the following blood tests -
* glucose (laboratory measurement)
* blood gas (for pH and pCO2)
* plasma U&E – ensure samples are sent URGENTLY to lab
* finger-prick (near patient) blood ketones
* strict fluid balance including oral fluids and urine output, using fluid balance charts (urinary
catheterisation may be required in young/sick children)
* hourly capillary blood glucose measurements (these may be inaccurate with severe
dehydration/acidosis but are useful in documenting the trends. Do not rely on any sudden changes
but check with a venous laboratory glucose measurement)
* capillary blood ketone levels every 1-2 hours
* hourly BP and basic observations
* hourly level of consciousness initially, using the modified Glasgow coma score
* half-hourly neurological observations, including level of consciousness (using the modified Glasgow
coma score) and heart rate, in children under the age of 2, or in children and young people with a pH
less than 7.1, because they are at increased risk of cerebral oedema
* reporting immediately to the medical staff, even at night, symptoms of headache, or slowing of
pulse rate, or any change in either conscious level or behaviour
* reporting any changes in the ECG trace, especially signs of hypokalaemia, including ST-segment
depression and prominent U-waves
* twice daily weight; can be helpful in assessing fluid balance
13
A doctor should carry out a face-to-face review at the start of treatment and then at least every 4
hours, and more frequently if:
* children are aged under 2 years
* they have severe DKA (blood pH below 7.1)
* there are any other reasons for special concern.
At each face-to-face review assess the following:
* clinical status, including vital signs and neurological status
* results of blood investigations
* ECG trace
* cumulative fluid balance record.

Thyroid disease and annually thereafter
Coeliac disease - after if symptoms arise

123
Q

Three basic types of insulin regimens

A

Multiple daily injection basal–bolus insulin regimens
Continuous subcutaneous insulin infusion (insulin pump therapy):
One, two or three insulin injections per day: these are usually injections of short-acting insulin or rapid-acting insulin analogue mixed with intermediate-acting insulin.

124
Q

What does multiple daily basal bolus regime look like

A

: injections of short-acting insulin or rapid-acting insulin analogue before meals, together with 1 or more separate daily injections of intermediate-acting insulin or long-acting insulin analogue.

125
Q

What type of insulin is normally administered by cont SC therapy

A

Rapid acting insulin analogue or short acting insulin

126
Q

What do the injections of insulin that can be taken contain?

A

Short acting insulin or rpaid acting insulin analogue mixed with intermediate acting insulin

127
Q

What is ideal HbA1c level

A

<48 mmol/mol

128
Q

When strongly sus T2DM in children

A

have a strong family history of type 2 diabetes
* are obese
* are from a Black or Asian family background
* do not need insulin, or need less than 0.5 units/kg body weight/day after the
partial remission phase
* show evidence of insulin resistance (for example, acanthosis nigricans)

129
Q

When suspect diabetes that is not T1 or T2 eg monogenic or mitochondrial

A

diabetes in the first year of life
* rarely or never develop ketones in the blood (ketonaemia) during episodes of
hyperglycaemia
* associated features, such as optic atrophy, retinitis pigmentosa, deafness, or
another systemic illness or syndrome

130

A

C-peptide

131
Q

What do people with T1DM have immunisations against?

A

annual immunisation against influenza, starting when they are 6 months old.
* immunisation against pneumococcal infection, if they are taking insulin or oral
hypoglycaemic medicines

132
Q

What can happen after initial insulin treatment in T1DM

A

Honeymoon period where more sensitive to insulin so dont need as high a dose

133
Q

What can do when exercsie to avoid hypo

A

Eat carb heavy foods before (if <7 glucose)
Monitor blood sugar before and after to adjust insulin accordingly

134
Q

Target plasma glucose

A

fasting plasma glucose level of 4 to 7 mmol/litre on waking
* a plasma glucose level of 4 to 7 mmol/litre before meals at other times of the
day
* a plasma glucose level of 5 to 9 mmol/litre after meals
* a plasma glucose level of at least 5 mmol/litre when driving

135
Q

How to treat mild/mod hypos

A

Give oral fast-acting glucose (for example, 10 to 20 g) (liquid carbohydrate may
be easier to swallow than solid).
* Be aware that fast-acting glucose may need to be given in frequent small
amounts, because hypoglycaemia can cause vomiting.
* Recheck blood glucose levels within 15 minutes (fast-acting glucose should
raise blood glucose levels within 5 to 15 minutes), and give more fast-acting
glucose if they still have hypoglycaemia.
* As symptoms improve or blood glucose levels return to normal, give oral
complex long-acting carbohydrate to maintain blood glucose levels, unless the
child or young person is:
- about to have a snack or meal
- having a continuous subcutaneous insulin infusion

136
Q

How to treat hypos in hospital
