| Objective: To explore the correlation between blood oxygen saturation, red blood cell count, hemoglobin content, coagulation function and pregnancy complications, and provide reference for prenatal care in plateau areas. Methods: Retrospective study method was used to 146 pregnant women with pregnancy complications and 135 cases without pregnancy complications from January 2019 to January 2020. The data of general conditions, blood oxygen saturation, red blood cell count, hemoglobin content, coagulation function, pregnancy complications were collected, and the differences between the two groups were compared. Results: The red blood cell count and hemoglobin content in the observation group were lower than those of the control group, and the D-dimer was higher than that of the control group, P＜0.05. Patients with anemia had lower red blood cell count and hemoglobin than the control group, and D-dimer was higher than the control group， P＜0.05. Patients with pregnancy hypertension had lower hemoglobin than the control group, and D-dimer was higher than the control group，P＜0.05. Patients with low weight fetuses had lower red blood cell count, hemoglobin than the control group, and D-dimer was higher than the control group, P＜0.05. The red blood cell count in patients with premature birth was lower than that in the control group, and D-dimer was higher than that in the control group, P＜0.05. Patients with fetal distress had lower red blood cell count, hemoglobin than the control group, and higher D-dimer than the control group, P＜0.05. Conclusion: Maternal antenatal care still needs to be strengthened in plateau areas. Red blood cell count, hemoglobin, and D-dimer may have a certain relationship with complications of pregnancy in plateau areas. The determination of erythrocyte count, hemoglobin reduction and plasma D-dimer increase and the prediction of pregnancy complications still need to be studied. |
