目的:探讨健康产妇临产和顺产后短期内血常规变化与正常参考区间。方法:以378例足月、单胎、头位、顺产的健康产妇为研究对象,分别于临产时与顺产后24h测定与分析产妇的血常规,包括红细胞、白细胞、血小板、血红蛋白、红细胞压积、中性粒细胞。结果:健康产妇顺产后的红细胞、血小板、血红蛋白、红细胞压积均显著低于临产时,差异均具有统计学意义(P<0.05);健康产妇顺产后的白细胞、中性粒细胞均显著高于临产时,差异均具有统计学意义(P<0.05)。结论:该研究建立了健康产妇临产和顺产后短期内血常规参考区间,可作为产妇临产与顺产后短期内血常规检测的临床参考依据,以评估产妇的健康水平。 Objective: To investigate the short-term changes in blood routine and normal reference interval of healthy pregnant women after labor and delivery. Methods: A total of 378 healthy pregnant women with full-term, single-birth, head-head and spontaneous labor were enrolled in this study. The blood routine was determined and analyzed at 24 hours after labor and at the end of delivery, including red blood cells, white blood cells, platelets, hemoglobin, , Neutrophils. Results: The levels of erythrocyte, platelet, hemoglobin and hematocrit in healthy pregnant women after birth were significantly lower than those at the time of labor (P <0.05), and the number of leucocytes and neutrophils in healthy pregnant women was significantly higher than that after labor During labor, the differences were statistically significant (P <0.05). CONCLUSION: This study established a reference interval of blood routine for healthy maternal inoculation and short-term follow-up, and could be used as a clinical reference basis for short-term blood routine examination after labor and delivery to evaluate the maternal health.
