Basic story is 22 G1P0 F at 9 wks w/ viable IUP presenting w/ RLQ pain x 1.5 mos and persistent N/V for 2-3 wks, unable to tolerate PO. WBC 19 on initial labs. MRI abd/pelvis neg for appy, TVUS neg for ectopic, torsed ovary, shows viable IUP w/ appropriate FHR. After w/u pt being treated for presumed hyperemesis gravid arum. I signed this pt out and check back approx 10 hrs later and pt is still in ED after 6 L D5 NS and multiple rounds antiemetics and an ob consult recommending more D5 NS and antiemetics. This is 22 hrs after initial assessment. Is this an appropriate ED course for this pt? Do we manage hyperemesis gravid arum in the ED for 22+ hrs or should this pt be admitted to an inpatient service for management?
