Endocrine emergencies: integrated approach

The idea that organises this page is deceptively simple. Every endocrine emergency is the same shape of problem seen from a different angle: a hormone axis has failed, the body's compensation has run out, and the child now sits in a metabolic and haemodynamic collapse that only the missing or blocked hormone can reverse. The resuscitation is also the same shape: secure the airway, get intravenous access, check the bedside glucose and the blood gas, send the electrolytes, and then give the empiric life-saving therapy before the confirmatory endocrine test returns. What changes from emergency to emergency is only which hormone you reach for — insulin, hydrocortisone, a beta-blocker with an antithyroid drug, or hypertonic saline. [1] [5]

This page synthesises the shared approach across the four dominant paediatric endocrine emergencies, linking to the dedicated leaves for diabetic ketoacidosis and the hyperosmolar hyperglycaemic state, adrenal insufficiency and adrenal crisis, hyperthyroidism and Graves disease, and diabetes insipidus and SIADH. It does not repeat their full pathways. The integrated leaf teaches what those emergencies share: the recognition, resuscitation, communication, the ICU escalation and the cross-cuting pitfalls that catch the registrar who knows each disease separately but cannot see the pattern. [1] [12]

Overview & Definition

A child who arrives vomiting, dehydrated and breathless, or drowsy with a low blood pressure, or seizing with an abnormal sodium — that is the opening scene of a paediatric endocrine emergency. The condition is an acute, potentially life-threatening failure of a hormone axis, where the missing or excess hormone produces a metabolic and haemodynamic collapse, and its replacement or blockade is the immediate life-saving treatment. [1] [5]

The first thing to understand is that these emergencies do not announce themselves by name. The child does not say "I am in adrenal crisis"; the child says "I feel sick and I cannot stop vomiting", and the nurse says "the blood pressure is not coming up". The endocrine diagnosis lives in the pattern of the blood results, and the job of the clinician is to reach for the bedside glucose and the electrolytes early enough that the pattern becomes visible before the child arrests. That is the heart of the integrated approach: the endocrine emergency is a metabolic pattern hiding inside a sick child, and the bedside tests are the torch that finds it. [3] [5]
