SS_OB 1.19 Describe the anaesthetic management of early pregnancy conditions such as  ectopic pregnancy

  • Major comorbidity associated with ectopic pregnancy: death, infertility, recurrent ectopic pregnancy
  • Risk factors:
    • Prior ectopic
    • Prior tubal surgery
    • PID
    • Congenital anatomic distortion
    • Previous pelvic/abdominal surgery
    • Use of intra-uterine device
    • Delayed ovulation
    • Progesterone only OCP
    • Smoking
    • Assisted reproductive procedures

  • Two main presentations: Stable and emergency rupture
  • Stable:
    • Often can await diagnosis of serial bHCG’s and USS
    • May have expectant management if asymptomatic and early diagnosis (50% spontaneously resolve)
    • Medical management: Methotrexate
    • Surgical: Laparoscopic surgery - salpingostomy, salpingotomy, salpingectomy
    • GA + ETT, wide bore IVL as risk of rupture and bleeding

  • Emergency (15%) of cases:
    • Present with fallopian tube rupture and arterial bleeding
    • Need resus and urgent transfer to OT
    • 2x wide bore IVL’s, G&H
    • RSI + ETT
    • Consider cell salvage and rapid infusor + A-line and  CVL in haemodynamic instability
    • Temperature monitoring, fluid warmer, forced air warmed
    • Surgical: Lap vs open laparotomy
Implanted ectopic is usually tubal (98%) but can implant anywhere, most serious presentation is interstitial + uterine rupture => massive bleeding, cervical implantation can also present with massive bleeding as the cervix cannot contract
