Manual Vacuum Aspiration (miscarriage/abortion <=12 wks)
Manual Vacuum Aspiration (miscarriage/abortion <=12 wks) operating theatre - gynaecology
- Incomplete/missed miscarriage
- Induced abortion <=10-12 wks (provider norms per MTP Rules)
- Retained products with sepsis (post-antibiotic start)
- Success rates/failure -> repeat
- Uterine perforation/infection/bleeding risks
- Discuss gestation- and indication-specific RhD prophylaxis
- Contraception same-day offer
- MVA syringe 60 mL + cannulae 4-12 mm
- Tenaculum, sound, antiseptic, speculum
- Histology container (molar suspicion always)
- Paracervical block 1% lignocaine ± light sedation
Absolute contraindications: Suspected ectopic (treat as such) · Haemodynamic instability uncorrected · Molar pregnancy needs suction-evacuation setup (specialist)
Preparation
- CBC/group&save; sepsis screen if febrile
- Analgesia plan (paracervical block ± sedation)
- Aseptic prep; tenaculum traction reduces pain/perforation
- Sound to depth; choose cannula = weeks of gestation (mm)
- Create vacuum ~60 mL; evacuate with rotating strokes
- Inspect aspirate: products complete? vesicles?
- Confirm uterus contracted; minimal bleed at end
- No tissue obtained: reconsider ectopic/retroversion error
- Excessive bleeding: uterotonics; complete evacuation faster is haemostatic
Uterine perforation
Stop; observe stable small anterior perforations; laparoscopy/laparotomy for suspected visceral injury/unstable
Retained products
Repeat aspiration; antibiotics if infected
Infection/endometritis
Broad-spectrum course; sepsis pathway if systemic
Postoperative care
- For miscarriage, use the linked NICE NG126 2026 gestation-specific RhD criteria after confirming local applicability; induced abortion has a separate guidance context
- Analgesia + red-flag leaflet
- hCG follow-up plan
Admission & discharge
Admission/discharge guidance checked 2026-10-18 against the linked sources. This is a clinical checklist for an individual decision, not an automatic discharge order.
When admission or continued hospital care is needed
- Admit heavy ongoing bleeding/instability, suspected sepsis, severe uncontrolled pain or inability to complete safe outpatient care. Exclude ectopic pregnancy when the location/outcome is uncertain.
When clinic, day care or home care may be suitable
- Confirmed uncomplicated miscarriage can be managed expectantly, medically or by day-case surgery according to clinical suitability and patient preference.
Before going home
- Bleeding/pain and observations support home care; the diagnosis, chosen approach and possibility of incomplete treatment have been explained.
- After evacuation/anaesthesia, recovery and postoperative assessment are satisfactory, with transport/adult support when needed.
Discharge medicines and treatment changes
- Use only the regimen for the diagnosed type of miscarriage; provide analgesia and antiemetic treatment when needed. Review RhD care using the current applicable pathway.
Medicine doses — use only when indicated
Use the medicines selected for this patient. Listed alternatives are not instructions to prescribe all of them together. Confirm the actual remaining course, pregnancy/postnatal context and monitoring plan.
Pain relief when suitable; provide the selected miscarriage regimen in the treatment section.
- Indication: Short-term maternal postoperative/postpartum pain or other mild pain after assessment; adult ≥50 kg
- MSF oral monograph: no pregnancy or breastfeeding contraindication. The dose does not replace assessment of the cause of pain.
- Pain and functional recovery; investigate increasing pain, fever or other warning symptoms.
- Check all prescribed/OTC paracetamol, weight and hepatic risk; suspected excess dosing requires urgent assessment.
Tests, pending results and their reviewer
- NICE: after expectant management, review completion at 7–14 days; if symptoms resolve, provide a urine pregnancy test for 3 weeks.
- After medical management, urine pregnancy test at 3 weeks; a positive result or persistent bleeding, pain or fever needs assessment even when a test is negative.
Home care and counselling
- Explain expected bleeding/tissue passage, pain relief, hygiene and how to contact the early-pregnancy service. Offer grief support and contraception/future pregnancy advice.
Follow-up: when and what to review
| When | Action / responsible service |
|---|---|
If bleeding has not begun within 48 hours of misoprostol | Contact the treating service for review rather than repeating treatment independently. |
3 weeks after treatment | Check the home pregnancy test and symptoms; arrange review for a positive result or ongoing concerns. |
Return urgently
- Very heavy bleeding, fainting, severe/worsening pain, fever or offensive discharge needs urgent care.
