Episode notes
Broad Differential For Early Pregnancy Ascites
- Large-volume ascites in early pregnancy is an uncommon and alarming finding that demands broad thinking across obstetric and non-obstetric causes.
- Consider GI, GU, infectious, malignant, and pregnancy-specific etiologies rather than assuming a single system is responsible.
Always Confirm Intrauterine Pregnancy
- Confirm whether a suspected intrauterine pregnancy is truly intrauterine to avoid missing an ectopic.
- Use detailed ultrasound evaluation and consider ectopic locations (e.g., corneal) when imaging or clinical findings are atypical.
Paracentesis Labs Guide Next Steps
- Use serum-ascites albumin gradient (SAAG) and total protein to narrow ascites causes: SAAG <1.1 points away from portal hypertension.
- Send ascites fluid for extended cultures including TB and cytology when initial workup is unrevealing.
