Prepartum and postpartum complete blood cell counts and its difference
The results of pre- and postpartum complete blood cell count of parturients are shown in Table 4. Almost all displayed data illustrated the significant difference between prepartum and postpartum maternity apart from the lymphocytes in intrapartum fever expectant mother (P = 0.307). The elevated value of complete blood cell counts after labor included WBC, PLT, neutrophils, monocytes, and lymphocytes in both fever and non-fever parturients. On the contrary, postnatal RBC and Hb fallen remarkably. The mean of postpartum RBC fallen from 4.02 × 1012/L to 3.70 × 1012/L (P< 0.0001) in fever parturients and fallen from 3.98 × 1012/L to 3.81 × 1012/L (P< 0.0001) in afebrile maternity. For Hb, the value fallen from 119.75 g/L to 110.53 g/L (P < 0.0001) in fever group and fallen from 118.23 g/L to 113.55 g/L (P < 0.0001) in non-fever group.
In order to explore whether intrapartum fever would aggravate or alleviate the change of complete blood cell counts before and after delivery, we therefore used postpartum data of maternity complete blood cell count minus the corresponding prepartum data (Table 4). Table 4 illustrated that elevated WBC, PLT, and neutrophils, as well as reduced RBC and Hb, remained appreciably difference. The difference value of WBC (2.95 × 109/L vs. 2.28 × 109/L, P< 0.0001) and neutrophils (2.95 × 109/L vs. 2.28 × 109/L, P < 0.0001) preferred higher in intrapartum fever group, yet lower for PLT (10.60 × 109/L vs. 11.91 × 109/L, P = 0.023) in intrapartum fever subjects. Besides, RBC (-0.32 × 1012/L vs. -0.17 × 1012/L, P< 0.0001) and Hb (-9.21 g/L vs. -4.68 g/L, P< 0.0001) descended more obviously in fever maternity. However, monocytes (P = 0.185) and lymphocytes (P = 0.459) recommend pronounced discrepancy in intrapartum fever and afebrile group.
