| Objective: Based on the concept of Pernicious placenta previa(PPP)in the third edition of the eight-year edition and the eighth edition of the textbook on obstetrics and gynecology,According to these two concepts,this paper analyzed and discussed retrospectively the postpartum hemorrhage(PPH)and pregnancy outcome in the two groups,and explored the differences of health economics between the two groups at the same time.Methods: Select from January 2015 to December 2017 in the Department of Obstetrics and Gynecology at First Affiliated Hospital of Nan Hua University,and at the same time the termination of pregnancy in patients with PPP.According to the eighth year of the third edition of Obstetrics and Gynecology teaching materials define 57 cases as the study group,the eighth edition of Obstetrics and Gynecology teaching materials definition of 129 patients in the control group 1,select no history of cesarean section in patients with common type 112 cases of placenta previa(PP)was control group 2.This article is divided into two parts to discuss: The first part:(1)Analysis of the study group and the control group 1,control group 2 between the three groups of PPH and pregnancy outcomes;(2)The control group 1 was divided into placenta accreta group and non-placenta accreta group according to the presence or absence of placenta accreta.The PPH and pregnancy outcome were analyzed;(3)Analysis of Unattached scar group of placenta in the control group 1 and control group 2 between the two groups of PPH and pregnancy outcomes.The second part: Statistics on the total cost of three groups during hospitalization,and to discuss the differences of health economics between two groups of concepts.Result:(1)The average amount of bleeding,PPH rate,placenta accreta rate,postpartum blood transfusion rate and hysterectomy rate in study group were significantly higher than those in control group 1 and control group 2(P<0.05).There was no significant difference in preterm birth rate and neonatal asphyxia between the three groups(P>0.05).(2)The average amount of bleeding,PPH rate,postpartum blood transfusion rate and hysterectomy rate in placenta accreta group were significantly higher than the non-placenta accreta group,the difference was statistically significant(P<0.05).There was no significant difference in preterm birth rate and neonatal asphyxia between the two groups(P>0.05).(3)There was significant difference in placenta accreta rate between Unattached scar group of placenta in the control group 1 and control group 2(P<0.05);There was no significant difference in the average amount of bleeding,PPH rate,postpartum blood transfusion rate and hysterectomy rate,preterm birth rate and neonatal asphyxia between the two groups(P>0.05).(4)The total cost of hospitalization in three groups was higher than that in control group 1 and control group 2,while the total cost of hospitalization in control group 1 was larger than that in control group 2,suggesting among the three groups was statistically significant(P<0.05).Conclusion:(1)The eighth edition of the definition of PPP poor pregnancy outcome is still defined in the third edition of the PPP accounted for the main proportion.(2)The eighth edition of Obstetrics and gynecology in the placenta was not attached to uterine scar of PP which similar to the common type of PP,which does not significantly increase the occurrence of adverse outcomes of pregnancy.(3)From a health economics point of view,China is a developing country with a lack of obstetricians and a heavy clinical task.The definition of obstetrics and gynecology in the third year of the eight-year system can save health economics indicators to a certain extent,which is more reasonable than the definition of eighth edition of obstetrics. |
