What is the first-line management for a pregnant woman experiencing severe nausea and vomiting?

The first-line management for severe nausea and vomiting in pregnant women, commonly associated with hyperemesis gravidarum, typically involves intravenous fluids. This approach is crucial as it helps to prevent dehydration, correct electrolyte imbalances, and ensure proper hydration status. IV fluids can also provide a more rapid response compared to oral medications, particularly when the patient cannot tolerate oral intake due to the severity of symptoms.

In cases where a woman is experiencing such extreme symptoms, the use of intravenous therapy is vital as it allows for the administration of fluids and electrolytes directly into the bloodstream. This is important for both maternal and fetal well-being, as dehydration and electrolyte imbalances can lead to complications for both the mother and developing fetus.

Other options, while they might have their place in treatment protocols for nausea or other gastrointestinal discomforts, do not address the immediate need for rehydration and stabilization as effectively as intravenous fluids do in cases of severe presentation.
