Efficacy of Hydrogen Peroxide ( H2O2) in Controlling Placental Site Bleeding in Caesarian Delivery for Placenta Previa / Accreta Spectrum ( PAS)

Placenta accreta spectrum (PAS), encompassing the terms placenta accreta, increta, and percreta; abnormally invasive placenta; morbidly adherent placenta; and invasive placentation, is a leading cause of life-threatening obstetric haemorrage (1) . Currently, more than 90% of women diagnosed with PAS also have a placenta praevia (2), and the combination of both conditions leads to high maternal morbidity and mortality due to massive haemorrhage at the time of birth . Maternal mortality of placenta praevia with percreta has been reported to be as high as 7% of cases . Hydrogen peroxide is well-known for its antimicrobial and antiseptic properties. It is used to clean surgical cuts for better localization of bleeding focus in surgery and orthopedics and burn excisions to induce hemostasis . Topical application of hydrogen peroxide was proven to induce hemostasis and reduce operative time in both tonsillectomy and adenoidectomy .
