Clinical study on patterns of postpartum lochia / 中华围产医学杂志

ABSTRACT

Objective To study the rules of lochia rubra and draw normal pattern chart of post-partum lochia prospectively. Methods Samples were collected from parturients who had given birth in our hospital from July to December in 2002 consecutively including 191 women with cesarean section (CS) ,and 187 with spontaneous delivery. The amount of blood loss was measured and recorded everyday from 24 hours postpartumly to the day that lochia rubra was over by checking the special sanitary pads with squares on. All subjects were followed up on the 42nd day after delivery and the charts collected. Results The mean duration of lochia rubra in spontaneous delivery and CS group were (33. 9?12. 0) days and (39. 6?13. 1) days, respectively; and the 95% CI were 10-57 days and 14 -65 days, respectively (P = 0. 006). More recurrent lochia cases were seen in the CS group than that in spontaneous delivery group (103 vs 28, 66. 5% vs 19. 9%). Conclusions The duration of lochia rubra of CS group is longer than that of spontaneous delivery group. The 95% CI of the duration of lochia rubra is 10- 57 days in spontaneous delivery group while 14- 65 days in CS group. Lochia rubra will recurred several times during puerperium, especially in CS group.
