what is involved in person centred care?

A
3
Q

Facilitate long term health and well being

4

Scotland has 5th highest incidence of Type 1 Diabetes in the world

In Scotland 300 children under the age of 15 years are diagnosed with Type 1 Diabetes annually

1 in 4 are diagnosed in DKA, rising to 1 in 3 under the age of 5 years

In the UK 10 children die and 10 children suffer permanent neurological disability

5

thinner

thirsty

tired

using toliet more

6
Q

symtpoms of diabetes can be due to what 2 things?

blood glucose and blood ketone

7
Q

What is the benefit of managing HbA1c well at the starts?

A

Manage HbA1c good at the start and then this will have a legacy effect and work out better in the future

8
Q

what are some current strategies in place to support people with type 1 diabetes?

A

Education:

  • Team based DSN, practice nurse, dietitian, podiatrist, doctors
  • Structured education e.g. DIANE, Dose Adjustment For Normal Eating
  • Person with diabetes is main team member

Nutrition and Lifestyle management e.g. CHO counting, physical exercise

Skills training e.g. Home blood glucose monitoring, injection technique, hypos, sick day rules

Insulin- analogues, pens, pumps

9
Q

What are the different types of insulin you can get and their duration?

A

Rapid acting insulins eg insulin lispro*, insulin aspart* (Humalog®,Novorapid®,Apidra®)

Short acting insulins eg soluble insulin, actrapid, Humulin S.

Intermediate acting insulins eg Isophane insulin;insulatard,HumulinI.

Long acting insulins eg glargine*, detemir*, degludec

Continuous sub cutaneous insulin infusion (CSII)

10
Q

What do you need to check before you inject insulin?

A

Right insulin – check the name

Right dose – check strength and how much insulin to give. Check the numbers very carefully

Right time – with food? At bedtime?

Right way – via syringe, pen or pump?

11
Q

Why is insulin taken IV and subcutaneously and not orally?

A

Insulin is a polypeptide which is inactivated by the gastrointestinal tract therefore it needs to be injected subcutaneously (usual route) or intravenously (e.g. during illness or surgery)

12
Q

What happens to the insulin in the subcutaneous fat?

A

In the subcutaneous fat the Insulin molecule in solution has a tendency to self-associate into hexamers

Hexamers need to dissociate into monomers before absorption through the capillary bed. Thus soluble insulin is given 30 mins before eating

13
Q

why can rapid acting analogues be injected?

A

Rapid acting analogues do not associate and can be injected just before eating

14

Changing the structure of insulin or binding it to other molecules will change the rate of _________

A

absorption

15
Q

The amount of insulin injected for meals should balance the ___________ intake consumed
