Comparison of clinical characteristics and surgical efficacy between common and dangerous type placenta previa

ObjectiveTo summarize the clinical characteristics of common and dangerous type placenta previa, and compare the clinical efficacy of the surgical treatment in two types of placenta previa.

MethodsAmong 178 patients, 94 cases with common type placenta previa and 84 cases with dangerous type placenta previa were divided into the control group and observation group, respectively.After the detailed investigating disease history and examination, the age, pregnancy time, placenta implantation, attachment site and placenta previa type in two groups were summarized.After surgical treatment, the operation time, blood loss, diffused intravasular coagulation, hysterectomy and neonatal status between two groups were compared.

ResultsThe incidence rate of the placenta previa attaching anterior wall in control group (75.5%) was lower than that in observation group (92.9%) (P < 0.01).The differences of the constituent ratios of complete type, partial type and edge type between two groups were statistically significant (P < 0.01).The difference of the level of hemoglobin between two groups before operation was not statistically significant (P>0.05).After operation, the levels of hemoglobin in two groups were lower than that in normal people, the anemia signs in two groups were found, and the level of hemoglobin in control group was higher than that in observation group (P < 0.01).The operation time, blood loss, blood transfusion and postpartum hemorrhage in control group were lower than those in observation group (P < 0.01), the incidence rate of diffused intravasular coagulation of mother in control group was lower than that in observation group (P < 0.05), and the differences of the maternal postpartum haemorrhage, uterine resection rate, neonatal asphyxia rate, endotracheal intubation rate and mortality between two groups were not statistically significant (P>0.05).

ConclusionsThe placenta previa is great harmful to the mother, and the intraoperative and postoperative bleeding in dangerous type placenta previa are more.Timely surgical treatment can effectively improve the quality of life of patients with placenta previa.
