This week, Aebhric is again joined by Zach Andrews, who leads the latest episode of CoROM Conversations, which explores the recognition and management of severe malaria in resource-limited and austere environments. Drawing on field-relevant clinical reasoning, the discussion focuses on the progression from uncomplicated to life-threatening disease, with emphasis on Plasmodium falciparum as the primary driver of severe pathology. The conversation highlights the diagnostic challenges faced by remote medics, where laboratory confirmation may be delayed or unavailable, and underscores the importance of clinical pattern recognition, early intervention, and ongoing reassessment. Particular attention is given to complications such as cerebral malaria, severe anaemia, metabolic acidosis, and hypoglycaemia—all of which significantly increase mortality if not rapidly addressed. From a prolonged field care perspective, the episode integrates pragmatic strategies for stabilisation, monitoring, and evacuation decision-making. It reinforces the need for structured patient assessment using frameworks such as CABCDEFGH, along with trending vital signs over time. The discussion ultimately bridges tropical medicine with austere critical care, offering actionable insights for medics operating far from definitive care. Key Learning Points Severe malaria is a time-critical diagnosis, most commonly associated with Plasmodium falciparum, requiring immediate treatment even before confirmatory testing. Red flag features include altered mental status, respiratory distress, severe anaemia, hypoglycaemia, and shock. Hypoglycaemia is both a complication of malaria and a side effect of treatment (e.g., quinine), necessitating frequent glucose monitoring. In austere environments, clinical diagnosis often precedes laboratory confirmation, requiring high suspicion in febrile patients with travel or endemic exposure. Fluid management must be cautious, balancing the risks of hypovolaemia and pulmonary oedema. Prolonged care requires integration of nursing principles (HITMAN, SHEEP VOMIT) to prevent secondary deterioration. Early administration of parenteral antimalarials (e.g., artesunate where available) is critical to survival. Evacuation planning should be initiated early, but delays must not postpone life-saving interventions.

Check glucose early and often: Hypoglycaemia can be rapidly fatal and easily missed. Think beyond fever: Altered mental status or respiratory changes may be the first sign of severe disease. Your greatest tool is reassessment: Trends in vital signs are more valuable than single data points. Good nursing care saves lives: Positioning, hydration, hygiene, and monitoring are critical in prolonged care environments. Suggested References World Health Organization.
