Situation: A 30-year-old woman, gravida 3 para 3, gave birth vaginally to a healthy term newborn at a district hospital. She is breastfeeding, and the nurse on the postpartum ward cares for her during the first days after birth.

According to the usual pattern of lochia, during which period after birth is lochia serosa expected?

## 해설

Lochia follows a predictable sequence. Lochia rubra (red) lasts about days 1 to 3, lochia serosa (pink to brown) about days 4 to 10, and lochia alba (yellowish white) from about day 10 through 4 to 6 weeks.

Understanding Lochia Progression

After vaginal delivery, the uterus sheds the decidua, blood, and mucus that accumulated during pregnancy. This discharge is called lochia, and its color and composition change in a predictable sequence as the placental site heals and the uterus involutes.

Lochia serosa is the transitional phase between the initial bloody discharge and the final pale discharge. It appears when bleeding from the placental site decreases, and the discharge becomes thinner and lighter in color.

The expected timeline is:

| Type of Lochia | Color and Character | Expected Time Frame |
| --- | --- | --- |
| Lochia rubra | Dark red, mainly blood with small clots | Days 1 to 3 |
| Lochia serosa | Pink to brown, serous with less blood | Days 4 to 10 |
| Lochia alba | Yellowish white, mainly leukocytes and mucus | Day 10 through weeks 4 to 6 |

Key point! The transition from rubra to serosa reflects the healing of the placental site. If lochia rubra persists beyond day 3 or returns after serosa has begun, consider retained placental fragments or subinvolution.

The BLiPP study by Marchant and colleagues documented that women’s reported vaginal loss after childbirth is considerably more varied in duration, amount, and color than the classic textbook description suggests. While the conventional teaching outlines clear phases, individual women may experience overlap or deviation from these exact day counts. This does not invalidate the standard framework used in nursing assessments, but it reinforces the need to evaluate each postpartum woman individually and to investigate any sudden change in amount, odor, or return to bright red bleeding.

For a breastfeeding mother, oxytocin release during feeding promotes uterine contraction and involution, which can transiently increase lochia flow. This is a normal physiological response and should not be mistaken for hemorrhage unless the amount is excessive or accompanied by other abnormal signs.

Watch out! A sudden increase in lochia, a foul odor, or a return to bright red bleeding after serosa has begun may signal infection or secondary hemorrhage and requires prompt evaluation.

Postpartum Lochia AssessmentExpected progression and warning signs
Lochia follows a predictable sequence: lochia rubra is dark red with small clots during days 1 to 3, lochia serosa is pink to brown from days 4 to 10, and lochia alba is yellowish white from about day 10 through weeks 4 to 6.

The change from rubra to serosa reflects healing of the placental site and progressive uterine involution. Assess color, amount, odor, and presence of clots at each postpartum check.

CautionIf lochia rubra persists beyond day 3 or returns after serosa has begun, consider retained placental fragments or subinvolution. Foul odor, heavy bleeding, or large clots also require prompt evaluation.

## 핵심 개념

- **lochia rubra** — Dark red postpartum discharge consisting mainly of blood with small clots, expected days 1 to 3.
- **lochia serosa** — Pink to brown postpartum discharge that is thinner and contains less blood, expected days 4 to 10.
- **lochia alba** — Yellowish white postpartum discharge composed mainly of leukocytes and mucus, from about day 10 through weeks 4 to 6.
- **subinvolution** — Slower than expected return of the uterus to its prepregnant size, which may present with persistent or recurrent bleeding.
