Abstract
Currently, the frequency of deliveries by cesarean section is steadily increasing. Independent childbirth in women with a uterine scar is one of the mechanisms of its reduction. Meanwhile, the delivery of this category of patients through the natural birth canal requires the development of a safe and effective method for assessing scar integrity in the early postpartum period. For this purpose, a new instrumental diagnostics method has been developed, with its information content compared to manual examination data in an experimental model of the uterus. Each model was made of a bovine heart and had three defects with diameters less than 0.5 cm, 0.5-0.8 cm and 0.8-1.2 cm. Defects with diameters less than 0.5 cm were not detected by any of the methods studied. Defects with a diameter of 0.5-0.8 cm were detected using the developed device in 90 % (45/50) of cases and using manual examination in 44 % (22/50) of cases (χ2 = 23.93, p < 0.001), defects with a diameter of 0.8-1.2 cm being detected in 100% (50/50) and 98% (49/50) of cases, respectively (χ2 = 1.01, p = 0.32). The information content of the instrumental model exceeds that of the manual study by 1.34 times (RR = 1.34, 95 % CI 1.09-1.65, p < 0.05). Therefore, the possibility of testing this device in clinical trials needs to be considered.
