abstract

  • OBJECTIVE: To describe and compare the duration of lochia in seven groups of women; to investigate the occurrence of a possible "end-of-puerperium" bleeding episode; and to determine the frequency of bleeding episodes before postpartum day 56, which applies to the practice of the lactational amenorrhea method of contraception. DESIGN: Prospective longitudinal study with fortnightly follow-up, beginning within 7 days of delivery. SETTING: Five developing and two developed countries. PATIENT(S): Four thousand one hundred eighteen breast-feeding women. INTERVENTION(S): Postpartum lochia and all days of bleeding per vaginam were recorded. MAIN OUTCOME MEASURE(S): Duration of lochia, frequency of an end-of-puerperium bleeding episode, and frequency of postlochia bleeding episodes within 56 days of delivery. RESULT(S): The median duration of lochia was 27 days; it varied significantly among the centers (range, 22-34 days). In 11% of the women, lochia lasted >40 days. An end-of-puerperium bleeding episode around the 40th day postpartum was reported by 20.3% of the women. Bleeding within 56 days of delivery (separated from lochia by at least 14 days) occurred in 11.3% of the women and usually was followed by a confirmatory bleeding episode 21-70 days later. CONCLUSION(S): The duration of lochia varied significantly among the study populations, and long durations were not unusual. The significance of the end-of-puerperium bleeding episode is unknown. Most users of the lactational amenorrhea method will not experience a postlochia bleeding episode before postpartum day 56.
