Survey on the Duration of Lochia and some Effective Factores on it in Puerpera Women in Tehranʹs Educational Centers

Subject : In this research the duration of lochia and its relation with a number of obstetric variables has been studied. These variables are parity, mode of delivery, gestational age, fetal weight, use of syntocinon before delivery, placental site and maternal anemia. Our purpose of lochia in this investigation is lochia rubra and serosa. This research is a prospective descriptive-analytic study in which five hundred and sixteen parturient women who were native of Tehran have been studied. They were recruited form four educational hospital in Tehran. Researcher used of questionnaire, interview with patients, medical files and documents for collecting information. Recruits were wanted to report the duration of their bleeding and spotting from first day of delivery until perfectly end of lochia. The criteria for end of lochia were seven consecutive days with out blood loss. Then 50 days from delivery, in follow up, patients were asked about the end of lochia and probably complications. Follow up was continuing every 2 weeks until be assured the end of lochia. The median duration of lochia was 38.16 ± 14.38 days (range2-90days). Only in 5 percent of women, lochia stopped until 2 first weeks and in most of them (51%) it lasted 5-6 weeks from delivery. Also findings shows its duration is only related with gestational age and fetal weight (p<0.0001). This duration was longer with increase fetal weight and shorter in preterm labor. Also among C-section women, the duration of lochia, in who had used of syntocinon before cesarean, was shorter than elective cesarean (P<0.05). Analysis of contemporary relation of variables shows that only fetal weight, without influence of another variables, has a direct relation with duration of lochia (P<0.0001). Obtained information of this research confirms a view that lochia persists for longer than is generally described in textbooks and in most cases prolong duration of it can be a normal process.
