Objective: To explore the relationship between maternal and fetal complications during pregnancy and hyperredness, so as to find effective prevention and management measures. Methods: A total of 172 pregnant and parturients who were recorded, regularly examined and delivered in Naqu People's Hospital from January 2017 to January 2019 were retrospectively analyzed, including the general physiological data in the early pregnancy (10-12 weeks gestation), late pregnancy (36-37 weeks gestation) and postpartum (within one week),The complications during the perinatal period were followed up, and they were divided into high red group (observation group) and no high red group (control group) according to whether or not they had high red. The laboratory indexes such as maternal blood, urine, feces, liver function and kidney function during pregnancy and the clinical symptoms such as the postpartum state were analyzed and compared between the two groups. To analyze and compare the pathological and physiological indicators of the general state, liver and kidney functions, blood system, placental umbilical cord and other pregnancy appendages of the neonates of the high red syndrome pregnant women and the neonates of the normal healthy pregnant women. Results: For coagulation function test, FHG (g/L) 2.40 0.64, APTT (S) 54.6 4.13, PT (S) 12.8 0.64, TT (S) 16.2 1.4 in HAPC group; Plateau control group: FHG (g/l) 2,16 0,34. The results of APTT(s), 48.2 3.91PT (S), 12.5 0.96, and TT (S) 13.2 3.2 were statistically significant (P<0.05). Compared with the complication rate in pregnancy, the complication rate in pregnancy of the parturients with hyperchromia was significantly higher than that in the control group, and the results between the two groups were statistically significant (P<0.05). The comparison of the incidence of neonatal diseases showed that the incidence of neonatal diseases in the hyperchromia group was higher than that in the control group,Discuss: The combination of hyperchromia among pregnant women easily affected the coagulation function and caused the dereliction of duty of coagulation mechanism, manifested as the increased incidence of postpartum hemorrhage,At the same time, the combination of hyperchromia also aggravated the complications of pregnant mothers and infants.
