A woman delivers vaginally and 20 minutes later develops brisk vaginal bleeding. The uterus is firm and well-contracted on palpation. Placenta has been delivered completely. The most likely cause of her haemorrhage is:
- A Uterine atony
- B Retained placental fragments
- C Genital tract laceration ✓
- D Coagulation disorder
Correct answer: C. Genital tract laceration
Explanation
The '4 T's' of PPH are Tone, Tissue, Trauma, and Thrombin. A firmly contracted uterus with complete placenta delivery excludes atony and retained tissue; therefore the source is trauma — a cervical, vaginal, or perineal laceration. Systematic inspection of the genital tract under good lighting is the next step. Coagulation disorders typically present later and with generalised oozing.
