Diabetic Ketoacidosis: Diagnosis and Treatment Hour by Hour, Fluids, Potassium, Insulin | Episode 12

A 19-year-old woman has been vomiting for two days and is breathing deep and fast. This whiteboard lesson explains diabetic ketoacidosis from the three-organ board: the triggers, the clinical picture, the three diagnostic findings, the anion gap and corrected sodium, the potassium paradox, and treatment in order: fluids, potassium, insulin. It ends with resolution, the switch to subcutaneous insulin and a worked case. In this episode you will learn: • How absent insulin and stress hormones produce ketoacids • Triggers and the clinical picture • Diagnosis and the bedside arithmetic: anion gap and corrected sodium • The potassium paradox • Fluids, then potassium, then insulin: doses and rates • Bicarbonate, resolution criteria, the switch to subcutaneous insulin and complications Chapters 0:00 A vomiting teenager 0:36 The three-organ board without insulin 1:24 Why today: the triggers 2:07 The clinical picture 2:49 The three diagnostic findings 3:45 Bedside arithmetic 4:45 The potassium paradox 5:22 Step one: fluids 6:15 Step two: potassium 6:51 Step three: insulin 7:43 Bicarbonate 8:32 When has it resolved 9:06 Switching to subcutaneous insulin 9:53 A worked example 11:06 Complications 11:56 Recap This is Episode 12 of the series “Diabetes Mellitus, Drawn From Zero”.
