Adult Hyperglycaemia Flashcards
Differentials for Hyperglycaemia
- Intoxication
- Opioid toxicity
- Envenomation
- Stroke
Focused assessment for Hyperglyceamia
- AEIOUTIPS
- MASS
- Qsofa
What is the QSOFA assessment
2 or more points > risk of sepsis
Altered GCS - 1 point
Respiratory rate > 22 - 1 point
SBP < 100 - 1 point
Hyperglycaemia clinical risks of deterioration
- Seizures
- LOC
- Respiratory distress
- Renal damage
- Arrythmias (electrolyte imbalance)
- Sepsis
- Shock
Care objectives for hyperglycaemia
- Identification of high-risk hyperglycaemia
- hydration where indicated.
Factors associated with increased risk of hyperglcaemic emergencies
- Children and young people with Known type 1 diabetes
- Unstable
What is the threshold for symptomatic hyperglycaemia / ketosis?
BGL ≥ 11 OR ketones ≥ 0.6 mmol/L
Symptomatic hyperglycaemia may indicate underlying diabetes or other health issues.
What is a key characteristic of diabetic patients taking SGLT2 inhibitors?
They may present with raised ketones but normal BGL
SGLT2 inhibitors can influence ketone levels independently of blood glucose levels.
What constitutes mild to moderate hyperglycaemia / ketosis?
BGL 11 - 27.8 AND / OR ketones 0.6 - 3 mmol/L
Patients may show mild diabetes-related illness symptoms.
What are some clinical signs of mild diabetes-related illness?
- Mild lethargy
- Dry mouth / thirst
- Polydipsia
- Polyuria
These symptoms can indicate a mild state of hyperglycaemia.
What should be excluded when diagnosing mild to moderate hyperglycaemia?
- Acute coronary syndrome
- Infection / sepsis
These conditions may require emergency department care.
What defines severe hyperglycaemia / ketosis?
Any of:
* BGL > 27.8
* Ketones > 3 mmol/L
* Less than adequate perfusion
* Clinical features of DKA
* Clinical features of HHS
DKA stands for Diabetic Ketoacidosis and HHS stands for Hyperglycemic Hyperosmolar State.
What are clinical features of DKA?
- Altered conscious state
- Kussmaul breathing / tachypnoea
- Ketotic breath
- Dehydration
- Profound thirst
- Nausea / vomiting
- Abdominal pain
DKA is a serious condition requiring immediate medical attention.
What are clinical features of HHS?
- Altered conscious state
- Dehydration
HHS can be life-threatening and needs urgent care.
What is the initial IV fluid treatment for adults with severe hyperglycaemia?
Normal Saline 1000 - 2000 mL IV
Administer over 1 hour if BP > 90 mmHg.
What should be done if there is an inadequate response to IV fluid in adults?
Escalate to MICA for Consideration of vasopressors as per CPG A0705 Shock
Inadequate fluid response may indicate shock or severe dehydration.
What is the initial IV fluid treatment for paediatric patients?
Normal Saline 10 mL / kg IV titrated to perfusion status
Pediatric dosing must be carefully monitored for effectiveness.
What is the risk of fluid overload?
History of cardiac failure
Chronic renal failure
Elderly
All other patients include chronic renal failure and elderly.
What is the administration guideline for normal saline if BP > 90mmHg?
Administer over 1 hour.
What is the administration guideline for normal saline if BP ≤ 90mmHg?
Administer as bolus.
What are the care objectives for administering normal saline?
Identification of high-risk hyperglycaemia and hydration where indicated.
What are factors associated with increased risk of hyperglycaemic emergencies?
Children and young people with known type 1 diabetes, unstable glycaemic control, diabetes medication omission (especially insulin), use of an insulin pump, past DKA, acute infection and sepsis, pancreatitis, myocardial infarction/unstable angina, trauma, surgery or burns, medications (corticosteroids, atypical antipsychotics, immunosuppressive agents, SGLT2i), alcohol and recreational drugs, elderly people.
Why can the use of an insulin pump lead to hyperglycaemia and DKA?
As only rapid-acting insulin is administered by pumps (no long-acting insulin is used), any interruption to use of the pump can rapidly lead to hyperglycaemia and DKA.
What are the specific medications that can increase the risk of hyperglycaemic emergencies?
Corticosteroids, atypical antipsychotics, immunosuppressive agents, SGLT2i.
What are the considerations for elderly people regarding DKA?
Signs of DKA may be subtle, mortality rates may be higher, and type 1 diabetes can present at any age.
