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 .
* Population of study: A total of 84 pregnant patients with placenta previa / Accreta spectrum. * Study location: Obstetrics and Gynecology Kasr Al-Ainy Hospital , Faculty of Medicine , Cairo University. The aim of the study is to evaluate the efficacy of hydrogen peroxide for controlling bleeding from placental bed in caesarian section for placenta previa/ Accreta spectrum (PAS). • This is a randomized controlled trial including a total number of 84 patients representing study group , randomized in 2 equal groups , using computer generated randomization sheet on (Medcalc ®) . Group A : hydrogen peroxide group (n=42) Group B : control group (normal Saline solution) (n=42) .

Skin is incised either midline or Pfannenstiel incision according to clinical situation , bladder dissection will be done , uterus will be incised by transverse lower segment incision , followed by delivery of the baby. Uterine massage , ecbolics \& a trial for delivery of the placenta will be done Irrigation of the placental bed with 100 ml 3% hydrogen peroxide , followed by packing with a towel highly soaked hydrogen peroxide solution (Pozitif Kimya, İstanbul, Turkey) , freshly prepared by a 50% dilution with a normal saline solution
