Which is a clinical indication for parenteral nutrition in hyperemesis gravidarum?

• A. Vomiting not controlled with supportive care within 48 hours
• B. Fluid and electrolyte imbalances
• C. Patient refusal of EN tube placement
• D. Intolerance to EN trial and supportive care measures

Answer: (D)

In hyperemesis gravidarum, the use of parenteral nutrition is warranted when the gut cannot be used to deliver enough nutrients despite trying enteral feeding and supportive care. The option describing intolerance to enteral nutrition and failure to meet nutritional needs through the GI tract captures the situations where IV nutrition is necessary to prevent maternal malnutrition and support fetal well-being. Vomiting not controlled within a set timeframe isn’t a definitive trigger by itself, since decisions depend on whether enteral nutrition can actually be delivered and sustained. Fluid and electrolyte issues are addressed primarily with IV fluids and replacements, not by PN unless enteral feeding is not possible. Refusal of an EN tube could complicate management, but the core indication for PN remains the inability to tolerate or achieve adequate nutrition enterally.
