Results of positive vaginal secretion culture
For all 1797 parturients who undergone the fever during childbirth,
vaginal secretion culture was performed. Out of 1797 intrapartum fever
women in labor, 276 cases (15.36%) were tested with positive vaginal
secretion culture (The detailed results of the vaginal secretion culture
were presented in Figure S3). We then further subdivided positive
section into gram-positive bacteria (G+), gram-negative bacteria (G-),
and fungus, as for each group, the number of positive women was 122, 69,
and 85, respectively. Table 5 describes the pre-, intra-, and postpartum
complete blood cell count in three subgroups. From Table 5, we could
find the value of the positive test results difference mainly existed in
RBC, Hb, and PLT, including prepartum RBC, Hb, and PLT, intrapartum RBC
and Hb, as well as postpartum PLT. The value of prepartum RBC was 4.12 ×
1012/L, 4.10 × 1012/L, and 3.93 ×
1012/L for subgroup G+, G-, and fungus, respectively
(P = 0.009). And for intrapartum RBC, the matching value was 4.13
× 1012/L, 4.20 × 1012/L, and 3.97 ×
1012/L (P = 0.011). But this difference did not
exist in postpartum (P = 0.984). The changing trend of Hb was
consistent with RBC (P =0.025, 0.010, and 0.071 for pre-, intra-,
and postpartum RBC, respectively). However, the value of PLT showed
different tendency. Prepartum and postpartum PLT manifested difference
but not in intrapartum (P =0.022, 0.080, and 0.014 for pre-,
intra-, and postpartum RBC, respectively). In addition, post hoc test
(results not shown) suggested that the difference appeared in fungus
with G+ or G- but not G+ with G-. In other words, the difference
principally occurred in fungus with bacteria rather than different
bacteria. Nonetheless, the value of WBC, neutrophils, monocytes, and
lymphocytes in three groups presented no significant difference.
