NO DRUG THERAPY IN PRIMARY CARE (RECOGNITION & REFERRAL)
Emergency admission, now. Thirst, polyuria and weight loss progressing to vomiting, abdominal pain, deep sighing (Kussmaul) breathing and a fruity smell on the breath. Diagnosis is glucose above 250 mg/dL, arterial pH below 7.3, bicarbonate below 15 mEq/L, and ketones in blood or urine. Check a capillary glucose and ketones if you can, but a patient who looks like this goes to hospital whether or not you can measure them. - Refer, with advice
Children decompensate faster and are at risk of cerebral oedema during treatment. Emergency transfer; do not attempt rehydration protocols in the clinic.
No dose - referral pathway, no medicine given in primary care
- HOSPITAL ONLY. StatPearls: intravenous insulin by continuous infusion is the standard of care, with hourly glucose monitoring. There is no outpatient version of this.
- DO NOT give insulin before potassium is known. StatPearls requires a potassium of at least 3.5 mmol/L before insulin is started - giving insulin first can cause fatal hypokalaemia.
- It can be the FIRST presentation of diabetes. A previously well young person with these symptoms has new type 1 diabetes until proved otherwise - see [Type 1 Diabetes].
- Infection, missed insulin doses, corticosteroids, thiazides and SGLT-2 inhibitors are the common precipitants. SGLT-2 inhibitors can produce ketoacidosis with a near-normal glucose.
- Abdominal pain in DKA is often taken for a surgical abdomen. Check ketones before referring the pain instead of the patient.
