Ectopic Pregnancy
• 1 – 2 % of all pregnancies• 9 % of pregnancy-related deaths in the US• 50 % reduction in mortality rates since 1980s

Risk Factors
• Conditions that damage the integrity of the tube and impair smooth muscle contractions and ciliary beating.

History
• Most common Sxs are 1st trimester bleeding and abdominal pain (unruptured)
• Clinical Hx should include:– Pregnancy dating – Onset and intensity of Sxs– Review of risk factors

Physical Therapy
• Assess for peritoneal signs:– Rebound & cervical motion tenderness (poss.
hemo-peritoneum)– Inspection of cervical os for POCs (Ectopic vs SAB)– Pathology (decidual cast vs POCs)

Imaging
• Trans-vaginal US• A GS containing a YS should be identified by
5.5 weeks GA• Hetero-topic pregnancy: 1 in 4000
spontaneous pregnancy• Diagnostic challenge: Pregnancy is not
identified

Laboratory Tests• B-hCG Discriminatory Level:– 1,500 – 2,000 IU/L– Not perfect: Viable IUP not detected by US reported
up to 4,300 IU/L.
• Serial B-hCG:– Most pregnancies (99 %) increase by 50 % in 48 hrs
• 1 % of viable IUP have slower rates of increase• 20 % of ectopics increase by 50 % in 48 hrs
– Monitor until undetectable. Ruptured ectopic have been documented at very low or falling B-hCG.

Laboratory Test

Laboratory Tests
• Blood Type and Rh status– Rh negative to receive Rh (D) immune globulin
(RhoGam)

Treatment
• Methotrexate vs. Open or Laparoscopic surgery vs. Expectant management.
• Medically unstable or hemorrhage Surgery• Choice should be based on patient preference• 2007 Cochrane review found no difference in
success rates between laparoscopic salpingostomy and medical treatment

Medical Treatment
• Cost effective & avoids risk of surgery and anesthesia
• Methotrexate:– Folic acid antagonist that inhibits DNA synthesis
and cell replication– Selectively kill cyto-trophoblasts (rapidly dividing
cells at the fallopian tube implantation site), body then resorbs.

Medical Treatment
• Patient selection is important• Predictors of treatment failure– GS larger than 3.5 cm– Presence of cardiac activity– Presence of blood in the peritoneum– High progesterone level– High initial B-hCG level• There is NO level at which medical management is
contraindicated!

Medical Treatment
• Contraindicated in those with immune system compromise, damage to organs that metabolize MTX, or conditions that could be exacerbated by treatment.
• CBC, Cr, LFTs needed!

Medical Treatment
• Regimens– Trials have involved single-dose, two-dose, and
multi-dose regimens. – Single Dose preferred
• Adverse Effects– GI effects• Rare:
– Severe neutropenia– Reversible alopecia– Pneumonitis
