The discharge of a mass of rotten meat is a common phenomenon after childbirth, and the components of rotten meat are often placenta and meconium tissue, which can be diagnosed through pathological examination, as follows: 1. placenta: during childbirth, the placenta is not completely discharged, and some of it remains in the uterine cavity of the mother, and is discharged with the meconium during uterine contraction, which can result in the discharge of a mass of rotten meat at the same time as the discharge of meconium. It is recommended to go to the obstetrics department of the hospital for ultrasound examination to clarify whether the placenta is completely discharged in the uterine cavity and give the corresponding treatment; 2, meconium: during delivery, the meconium in the uterine cavity is not completely stripped with the placenta, and there is still some residue, which can lead to the discharge of a large mass of rotting flesh during the discharge of nightmare. You can take misoprostol orally under the guidance of a doctor to strengthen contractions and promote meconium discharge. If the meconium remains for a long time, or if there is a lot of residual tissue, a curettage can be performed if necessary. If there is still a large amount of malodorous discharge beyond the above mentioned time, it may be a case of incomplete postpartum malodorous discharge, so it is recommended to go to the hospital for ultrasound and gynecological examination to make a clear diagnosis and provide symptomatic treatment.
