HYPONATREMIA Part 3: Management, Correction, ODS & Cases | MRCP

Master hyponatremia management: safe sodium correction rates, hypertonic saline dosing, osmotic demyelination syndrome (ODS), and 3 clinical cases — by an MRCP Examiner. In Part 3 of this hyponatremia series, we close the loop on management. If you've mastered the framework (Part 1) and the diagnostic algorithm (Part 2), this video is where clinical decisions become safe actions. 🔑 What you'll learn: The 4-decision management algorithm applied to 3 real clinical cases Sodium correction ceilings: 4–6, 6–8, 8–10 mmol/L and the 18 mmol/L 48-hour cap When and how to use hypertonic saline (European vs North American protocols) Osmotic demyelination syndrome (ODS): mechanism, risk factors, and prognosis The autocorrection trap in hypovolaemic hyponatremia — and how to prevent it The re-lowering rescue protocol: dextrose + desmopressin step by step 6 classic errors that cause ODS — and how to avoid every one ⏱️ Chapters: 0:00:00 - Introduction & Series Overview 0:00:35 - 6 Anchors from Parts 1 & 2 0:01:27 - 4 Learning Objectives 0:02:30 - The 4-Decision Management Algorithm 0:03:42 - Decision 3: Setting the Correction Ceiling 0:04:28 - Decision 1: Acute vs Chronic Hyponatremia 0:06:14 - Decision 2: Symptom Severity Categories 0:10:40 - Decision 4: Monitor and Adjust 0:12:25 - Guidelines: European vs North American Protocols 0:15:13 - Case 3: Marathon Runner — Acute Severe Hyponatremia 0:17:54 - Hypertonic Saline Bolus Protocol 0:21:36 - Case 3 Execution & Sodium Trajectory 0:22:47 - Management Pathways: Chronic, Acute & Severe 0:24:32 - Case 1: Chronic Thiazide-Induced Hyponatremia 0:27:00 - Case 2: Autocorrection Trap & ADH Switch-Off 0:31:54 - Osmotic Demyelination Syndrome: Mechanism & Risk Factors 0:36:36 - Re-lowering Protocol: Dextrose & Desmopressin 0:37:37 - 6 Classic Errors That Cause ODS 0:38:53 - 6 Commitments: Management Summary 0:40:15 - Full Series Recap: Hyponatremia Parts 1, 2 & 3 🎓 About ClinicalMedEd ClinicalMedEd is created by Dr. Raza Ali Akbar — Senior Consultant Internal Medicine (HMC Qatar), Clinical Associate Professor (Qatar University), Assistant Professor (Weill Cornell Medicine–Qatar), current MRCP UK PACES Examiner, and former MRCP UK Question Author, FRCP (Edin).
