Problems solved by technology

However, my country implements the family planning policy, and there are few families with multiple births, so the application has certain limitations.
The Gonen formula classifies the indications of the previous cesarean section too carefully, but in clinical work, many pregnant women do not know the indications of the previous cesarean section, which may easily lead to missing content and bring some difficulties to the scoring
The Grobman formula involves race. In the research of Smith et al., it involves the gender of the fetus. However, since my country cannot conduct prenatal gender identification on fetuses, the application of this formula in my country will have certain limitations.
The body mass index in some prediction formulas is the pre-pregnancy body mass index, and some pregnant women do not know the pre-pregnancy weight, which leads to inaccurate calculation

Embodiment 1

[0028] Pregnant woman, 42 years old, 1) The previous cesarean section was a transverse incision in the lower uterine segment, and the incision during the operation had no tear, no infection, and healed well; New cesarean section indications, with vaginal delivery conditions; 3) This delivery is 146 months away from the previous cesarean section.

[0029] 1. Pregnancy 5 births 1 pregnancy 37 weeks, 2. Umbilical cord around the neck 3. Scarred uterus 5. Gestational diabetes 6. Recurrent miscarriage 7. Elderly pregnant women. The prenatal body mass index was 27.85, the parity was 1, the cervix was not dilated, and the membranes were not prematurely ruptured. The calculated P value was 72.42%, and vaginal trial labor was encouraged.

[0030] Results: A live baby boy was delivered vaginally on the left front of the occiput, and the mother's perineum was torn to the first degree, and the mother and child were safe in the end.

Embodiment 2

[0032] Pregnant woman, 20 years old, 1) The previous cesarean section was a transverse incision in the lower uterine segment, and the incision during the operation had no tear, no infection, and healed well; 2) The indication for the previous cesarean section did not exist, and this pregnancy had New cesarean section indications, with vaginal delivery conditions; 3) This delivery is 50 months away from the previous cesarean section.

[0033] 1. Pregnancy 3 births 1 pregnancy 38+4 weeks, 2. Scar uterus. The prenatal body mass index was 28.04, the parity was 1, the cervix was dilated 1 cm, and the membranes were not prematurely ruptured. The calculated P value was 90.12%, and vaginal trial labor was encouraged.

[0034] Results: A live baby boy was delivered in the left anterior vaginal cavity, with mild postpartum hemorrhage (uterine atony), and the mother and child were safe after treatment.

Embodiment 3

[0036] Pregnant woman, 25 years old, 1) The previous cesarean section was a transverse incision in the lower uterine segment, and the incision was not torn or infected during the operation, and healed well; New cesarean section indications, with vaginal delivery conditions; 3) This delivery is 48 months away from the previous cesarean section.

[0037] 1. Pregnancy 4 births 2 pregnancy 39+1 week, 2. Premature rupture of membranes 3. Hypertension during pregnancy 4. Scarred uterus. The prenatal body mass index was 25.6, the parity was 2, the cervix dilation was 3 cm, and the membranes were prematurely ruptured. The calculated P value was 95.82%, and vaginal trial labor was encouraged.

[0038] Result: A live baby boy was delivered vaginally on the left front of the pillow, and the mother and baby were safe.

Abstract

The present invention relates to the technical field of obstetrics and gynecology, in particular to a method for predicting the success rate of trial delivery of a scarred uterus, by analyzing the prenatal parity of pregnant women, prenatal body mass index, dilation of the cervix, and premature rupture of membranes. Data collection, and then use P=1 / [1+exp (‑0.785+1.3259x1‑1.5061x2‑1.2449x31‑1.4211x32+0.7617x4)]*100% to calculate, and predict the success rate of vaginal trial delivery according to the P value , to provide a reference index for pregnant women and doctors, data collection is easy, and the prediction success rate is high, especially suitable for the prediction of vaginal trial labor of pregnant women with scarred uterus in our country.

Description

technical field [0001] The invention relates to the technical field of obstetrics and gynecology, in particular to a method for predicting the success rate of trial delivery of a scarred uterus. Background technique [0002] my country's cesarean section rate continues to rise, so that more and more scar uterus formation. How to choose the appropriate delivery method has become a common concern of doctors and patients. Studies have shown that the incidence of complications of scar uterine vaginal delivery is lower than that of elective repeated cesarean section, and the incidence of complications of repeated cesarean section is lower than that of failed trial delivery. Under the premise of reasonable selection of indications, the success rate of vaginal labor trial with scarred uterus is about 75%. This is for a group, not for individual pregnant women. During prenatal consultation, clinicians and pregnant women are most concerned about the safety of vaginal trial labor wi...
