Fulminant C. difficile Colitis — ICU Decision Pathway

Recognition and rescue management of fulminant C. difficile infection with shock, ileus or toxic megacolon.

Shock with Ileus and Suspected Fulminant Colitis
Assessment StepFulminant disease is defined by physiology, not stool frequencyExplore Topic
Hypotension/shock, ileus or megacolon identifies fulminant CDI. Ileus may reduce diarrhea, so absence of frequent stool does not exclude life-threatening colitis.
Clinical ActionUse high-dose enteral vancomycin plus IV metronidazole
Give vancomycin 500 mg enterally four times daily for fulminant CDI and add IV metronidazole 500 mg every 8 hours; if ileus is present, add rectal vancomycin where feasible.
Reassessment / LoopReassess response and escalate
Trend physiology and organ function; if the patient is worsening, revisit diagnosis, source control and rescue options rather than repeating ineffective therapy.

Caution

Escalate — Red Flags & Critical Warnings

  • Escalate early for shock, rapidly progressive organ failure, dangerous ECG/airway findings or failure of initial therapy.
