ABSTRACT

Objective:

To explore and analyze the high risk factors of puerperal infection in eastern He'nan province, and to provide scientific basis for prevention of postpartum infection.

Methods:

The clinical data of 1 521 cases of puerpera in the First People's Hospital of Shangqiu and the People's Hospital of Xiayi County from August 2014 to October 2018 were retrospectively analyzed.Of the 1 521 cases, 91 cases with puerperal infection were enrolled in puerperal infection group, and 1 430 patients without puerperal infection were enrolled in puerperal uninfected group.The correlation of perineum incision, amniotic fluid contamination, soft birth canal injury, prenatal anemia, mode of delivery, placental residual, hemoglobin, birth process time, rupture time and bedtime with puerperal infection was explored.

Results:

The puerperal infection was associated with perineal incision, amniotic fluid contamination, prenatal anemia, postpartum hemorrhage, delivery mode and placental residue(χ 2=6.439, 5.269, 10.188, 4.862, 4.125, 6.663, all P<0.05). The duration of membrane rupture, hemoglobin, length of labor and bed rest in the puerperal infection group were (10.1±2.1)h, (110.5±10.8)g/L, (8.2±1.4)h, (2.8±0.6)d, respectively, which in the non-infection group were (11.2±2.5)h, (103.2±12.1)g/L, (11.7±1.8)h, (4.2±0.7)d, respectively, the differences between the two groups were statistically significant( t=-4.786, 6.205, -22.689, -21.355, all P<0.05).

Conclusion:

There are many factors that can cause puerperal infection, we should take preventive measures to against these risk factors in clinical practice, and to reduce the incidence of postpartum infection.
