Immediate Manual Replacement of the Uterus
Replace the uterus as soon as possible (option c) – this is the definitive first-line treatment for acute uterine inversion and must be performed immediately before the cervical ring contracts, which would make reduction significantly more difficult or impossible. 1, 2
Why Immediate Manual Replacement is Critical
- Time is tissue: The cervical ring begins to contract within minutes of uterine inversion, creating a constricting band that makes manual reduction progressively more difficult 1
- Hypotension with minimal bleeding is pathognomonic: This patient's presentation of shock with little vaginal bleeding is classic for uterine inversion – the hypotension results from vagal stimulation and the inverted uterus itself, not primarily from blood loss 1, 2
- Early intervention has the best prognosis: The best outcomes occur when diagnosis and manual reduction are performed immediately, before cervical ring contraction and before the need for laparotomy 1
Manual Replacement Technique
- Apply steady upward pressure on the inverted fundus through the vagina, pushing it back through the cervical ring 1, 2
- Use the palm of your hand to push the fundus upward toward the umbilicus 1
- If the placenta is still attached, do not remove it before attempting reduction – leave it in place during the initial replacement attempt, as removing it may worsen bleeding 2
- Perform this under adequate analgesia or general anesthesia if time permits 2
Why the Other Options Are Wrong
Option A (Methergine) is Contraindicated
- Never give uterotonics before reducing the inversion – methergine and other uterotonics will cause the cervical ring to contract further, making manual reduction impossible 2
- Uterotonics should only be administered after successful uterine replacement to prevent recurrence 2
- The FDA label for methergine indicates use for postpartum atony and hemorrhage 3, but this does not apply when the uterus is inverted
Option B (Fetal Pillow) is Not Standard
- A fetal pillow is not mentioned in standard management algorithms for uterine inversion
- This may refer to hydrostatic reduction techniques, which are second-line interventions if manual reduction fails
Option D (B-Lynch Suture) is Premature
- B-Lynch sutures are compression sutures used for uterine atony refractory to medical management 4
- This patient needs the uterus replaced first – surgical interventions come only after failed manual reduction attempts 1
If Manual Reduction Fails
- Proceed to laparotomy with combined abdominal and vaginal approach: apply opposing pressures on the cervical ring from above (through the abdomen) and on the uterine fundus from below (through the vagina) 1
- Surgical incision of the cervical ring (Haultain procedure) may be necessary if the above fails 1
- Hysterectomy is the last resort if all reduction attempts fail 4
Common Pitfall to Avoid
Do not give uterotonics before reducing the inversion – this is the most critical error that will convert a manageable emergency into a surgical one by causing irreversible cervical ring contraction 2
