Placenta previa presentation by YML

Placenta previa (pluh-SEN-tuh PREH-vee-uh) occurs when a baby's placenta partially or totally covers the mother's cervix — the outlet for the uterus. Placenta previa can cause severe bleeding during pregnancy and delivery. Some of the possible causes and risk factors of placenta previa include: Low implantation of the fertilised egg. Abnormalities of the uterine lining, such as fibroids. Scarring of the uterine lining (endometrium)

8. Condition - 1 Placenta previa → Bleeding at term( >37 week) (Painless bleeding) ↓ So Major type (3, 4) – bleed ↓ Treatment – Resuscitation → C-Section Note - In such condition we don’t do Pervaginal examination

9. Condition- 2 Placenta previ a – at term[ Not bleeding ] ↓ If PP is type 4 → Then only C-Section ( Totally covering oss) If PP is type 3 ( Partially covering oss) → Then Double setup examination/Examination under anesthesia Under anesthesia Drape the patient, keep another surgeon ready Do per vaginal examination ↓ If placenta moved away → Normal vaginal delivery If placenta not moved away → C-Section (Placenta still covering oss)

10. Condition - 3 Placenta Previa, at 32 weeks, [<34 week – Lung immature] ↓ No tocolysis ( Because bleeding) ↓ 1) Resuscitation 2) Steroids to the mother 3) Rest, sedation MCAFFEE JOHNSON REGIME Bleeding stops in 90% cases spontaneously But if bleeding doesn’t stops then → C-Section (10%)
