Dehydration with History of Diarrhoea or Vomiting: When Initial IV Rehydration Does Not Restore Circulation
This protocol addresses severe dehydration in a patient presenting after diarrhoea and/or vomiting, where initial intravenous rehydration therapy has not fully achieved the expected clinical response.
Clinical Scenario
Presentation: History of diarrhoea and/or vomiting with reduced urine output, and at least 2 of the following signs:
- Lethargic or unconscious mental status
- Weak or absent radial pulse
- Sunken eyes
- Skin pinch returning very slowly (> 2 seconds)
- Drinks poorly or not able to drink
When Initial Treatment Did Not Achieve Its Goals
Previous treatment: Oral rehydration solution (ORS) and intravenous Ringer lactate (Treatment Plan C) were administered for severe dehydration.
Goals not reached: Radial pulse did not become adequately palpable after the bolus, or the patient was not able to drink safely within the expected timeframe — indicating the need for structured next-step management.
Goals not reached: Radial pulse did not become adequately palpable after the bolus, or the patient was not able to drink safely within the expected timeframe — indicating the need for structured next-step management.
Next-Step Management
When complications arise during the rehydration course, the protocol directs specific, targeted interventions — including management of an electrolyte disturbance that may develop, and, should fluid-balance complications emerge, a distinct clinical response. The full decision sequence and regimen details are in the protocol.

- develops dyspnoea, cough and bibasal crepitations are heard on auscultation of the lungs: sit the patient up, reduce the infusion rate to a minimum and administer one dose of furosemide IV (1 mg/kg in children; 40 mg in adults).
