Retained Placental Fragments After Delivery
A fragment of placenta can remain adherent to the uterine wall after birth.
- ~2%: Occurrence rate (of vaginal deliveries)
- <30 min: Normal 3rd stage (placental delivery window)
- Uterine: Cavity involved (wall attachment site)
- Exam + US: Detection method (visual and ultrasound check)
How fragments stay behind
Placeholder: incomplete separation leaves fragment tissue attached to the wall.
The Thirty-Minute Delivery Time Threshold
Placenta undelivered past thirty minutes is classified as retained.
- 30 min: Threshold (active management guideline)
- With time: Risk rises (longer retention, more risk)
- Continuous: Monitoring (vitals and bleeding watch)
- Escalate: Action point (call for intervention team)
Why timing matters
Placeholder: delay past thirty minutes raises hemorrhage probability sharply.
Continued Bleeding and Infection Risk
Retained tissue blocks contraction, causing ongoing blood loss and infection.
- Hemorrhage: Main risk (postpartum blood loss)
- Infection: Secondary risk (endometritis from retained tissue)
- Reduced: Uterine tone (atony from incomplete emptying)
- Rising: Urgency (with time and blood loss)
Bleeding mechanism
Placeholder: fragment prevents full contraction, vessels stay open and bleed.
Manual or Instrumental Removal Procedure
Clinician removes retained tissue manually or with instruments under anesthesia.
- Manual / D&C: Method (hand or curettage removal)
- OR / bedside: Setting (depends on severity)
- Often used: Anesthesia (for pain control)
- Full evacuation: Goal (empty uterine cavity)
Removal technique
Placeholder: gentle sweep or curettage clears remaining placental fragments.
Ultrasound Confirmation of Complete Evacuation
Ultrasound scan confirms the uterine cavity is fully cleared.
- Ultrasound: Confirmation tool (post-procedure imaging)
- Empty cavity: Target (no residual tissue seen)
- Vitals check: Follow-up (monitor bleeding trend)
- Resolved: Outcome (complication addressed)
Confirming success
Placeholder: clean scan image confirms no fragments remain in cavity.
Placeholder: successful evacuation lowers bleeding and infection risk quickly.
