Lightning Learning: Ectopic Pregnancy
An ectopic pregnancy is when a fertilised egg implants and begins developing outside the uterus:
97% fallopian tubes
3% interstitial (area between fallopian tubes and uterus)
Can develop in a number of other areas
Affects 1-in-80 pregnancies. Pregnancy is not viable. Symptoms include lower abdominal pain and vaginal bleeding. Always consider ectopic pregnancy in women (of childbearing age) presenting with abdominal pain.
If fallopian tube ruptures it can be life-threatening due to bleeding.
Patient may present…
haemodynamically unstable with symptoms of ectopic pregnancy
with shoulder tip pain if large amount of bleeding
Mortality rate = 0.2%
Surgical: presents with peritonitis, large gestational sac, fallopian tube rupture
Methotrexate: gestational sac <3.5cm, no peritonitis, ability to closely monitor, no contraindications
