Introduction: The article describes modern approaches to the prevention of obstetric bleeding and blood-saving technologies in women who gave birth by caesarean section. It is especially important to pay attention to the timely detection of anomalies in the position of the placenta and attachment. The article analyzes the outcome of caesarean section in two groups with obstetric haemorrhage. The largest share of obstetric haemorrhage is the detachment of the normally located placenta and placental pathology. A prospective study has been conducted to assess the effectiveness of the phased control and treatment of hemorrhage during caesarean delivery. Objective: To evaluate the effectiveness of the phased control and treatment of haemorrhage during cesarean delivery. Methods: The authors divided all the patients into two groups depending on the methods of intraoperative treatment. In group I, haemorrhaging was treated by using the proposed step-by-step control and treatment tactics (cesarean section indications were haemorrhaging due to premature detachment of low or normally located placenta in the first group) and the second group were treated according to the Protocol of the treatment of haemorrhaging adopted in the hospital (indications for cesarean section was central placenta previa and uterine scar). Results: In the first group, compared to the control group, 80% (12) of type 2 and type 3 lower segmental bleeding prevailed, which indicates a high risk for the development of serious complications. In the first group, class 1 blood loss was diagnosed in 26.6% (4) cases, class 2 blood loss in 53.3% (8) cases, class 3 blood loss was diagnosed in 20.0% (3), class 4 blood loss was not present, which indicates successful treatment of bleeding. In the second control group, class 1 blood loss was diagnosed in 23.8% (5) cases, class 2 blood loss in 28.5% (6) cases, class 3 blood loss in 52.3% (11) cases, and class 4 blood loss were diagnosed in 14.2% (3) cases. Conclusion: The use of the method of step-by-step control and treatment of haemorrhage helps to reduce the number of com plications such as hysterectomies by almost 2 times.
