Postpartum period

Postpartum period is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Postpartum period rather than just read about it. In short: The postpartum (or postnatal) period begins after childbirth and is typically considered to last for six to eight weeks. There are three distinct phases of the postnatal period; the acute phase, lasting for six to twelve hours after birth; the subacute phase, lasting six weeks; and the delayed phase, lasting up to six months.

Key takeaways

  • Postpartum period belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Postpartum period to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Postpartum period from memory before moving on to harder problems.

Reference excerpt

The postpartum (or postnatal) period begins after childbirth and is typically considered to last for six to eight weeks. There are three distinct phases of the postnatal period; the acute phase, lasting for six to twelve hours after birth; the subacute phase, lasting six weeks; and the delayed phase, lasting up to six months. During the delayed phase, some changes to the genitourinary system take much longer to resolve and may result in conditions such as urinary incontinence. The World Health Organization (WHO) describes the postnatal period as the most critical and yet the most neglected phase in the lives of mothers and babies. Most maternal and newborn deaths occur during this period. In scientific literature, the term is commonly abbreviated to Px, where x is a number; for example, "day P5" should be read as "the fifth day after birth". This is not to be confused with the medical nomenclature that uses G P to stand for number and outcomes of pregnancy (gravidity and parity). A woman giving birth at a medical facility may leave as soon as she is medically stable, which can be as early as a few hours postpartum, though the average for a vaginal birth is one to two days. The average caesarean section postnatal stay is three to four days. During this time, the mother is monitored for bleeding, bowel and bladder function, and baby care. The infant's health is also monitored. Early postnatal hospital discharge is typically defined as discharge of the mother and newborn from the hospital within 48 hours of birth. The postpartum period can be divided into three distinct stages; the initial or acute phase, 8–19 hours after childbirth; subacute postpartum period, which lasts two to six weeks, and the delayed postpartum period, which can last up to six months. In the subacute postpartum period, 87% to 94% of women report at least one health problem. Long-term health problems (persisting after the delayed postpartum period) are reported by 31% of women. Various organizations recommend routine postpartum evaluation at certain time intervals in the postpartum period.

Acute phase

The first 6 to 12 hours after childbirth is the initial or acute phase of the postpartum period. During this time the mother is typically monitored by nurses or midwives as complications can arise. The greatest health risk in the acute phase is postpartum bleeding. Following delivery the area where the placenta was attached to the uterine wall bleeds, and the uterus must contract to prevent blood loss. After contraction takes place the fundus (top) of the uterus can be palpated as a firm mass at the level of the navel. It is important that the uterus remains firm and the nurse or midwife will make frequent assessments of both the fundus and the amount of bleeding. Uterine massage is commonly used to help the uterus contract. Following delivery, if the mother had an episiotomy or tearing at the opening of the vagina, it is stitched. In the past, an episiotomy was routine. However, more recent research shows that routine episiotomy, when a normal delivery without complications or instrumentation is anticipated, does not offer benefits in terms of reducing perineal or vaginal trauma. Selective use of episiotomy results in less perineal trauma. A healthcare professional can recommend comfort measures to help to ease perineal pain.

Infant caring in the acute phase

Within about 10 seconds after birth, the infant takes its first breath and the caregiver places the baby on the mother's chest. The infant's condition is evaluated using the Apgar scale. The Apgar score is determined by evaluating the newborn baby on five criteria which are summarized using words chosen to form an acronym (Appearance, Pulse, Grimace, Activity, Respiration). Until recently, babies were routinely removed from their mothers following birth. However, beginning around 2000, some authorities began to suggest that early skin-to-skin contact (placing the naked baby on the mother's chest) is of benefit to both mother and infant. As of 2014, early skin-to-skin contact, also called kangaroo care, is endorsed by all major organizations responsible for the well-being of infants. Thus, to help establish bonding and successful breastfeeding, the caregiver carries out immediate mother and infant assessments as the infant lies on the mother's chest. The caregiver removes the infant for further observations only after they have had their first breastfeed, depending on the mother's preference. The World Health Organization (WHO) also encourages skin-to-skin contact for the first 24 hours after birth to help regulate the baby's temperature.

Subacute postpartum period The subacute postpartum starts after the acute postpartum period concludes and can last for two to six weeks.

Physical recovery in the subacute postpartum period

In the first few days following childbirth, the risk of a deep vein thrombosis (DVT) is relatively high as hypercoagulability increases during pregnancy and is maximal in the postpartum period, particularly for women with C-section with reduced mobility. Anti-coagulants or physical methods such as compression may be used in the hospital, particularly if the woman has risk factors, such as obesity, prolonged immobility, recent C-section, or first-degree relative with a history of thrombotic episode. For women with a history of thrombotic event in pregnancy or prior to pregnancy, anticoagulation is generally recommended. The increased vascularity (blood flow) and edema (swelling) of the woman's vagina gradually resolves in about three weeks. The cervix gradually narrows and lengths over a few weeks. Postpartum infections can lead to sepsis and if untreated, death. Postpartum urinary incontinence is experienced by about 33% of all women; women who deliver vaginally are about twice as likely to have urinary incontinence as women who give birth via a cesarean. Urinary incontinence in this period increases the risk of long term incontinence. In the subacute postpartum period, 87% to 94% of women report at least one health problem. Kegel exercises are recommended to strengthen the pelvic floor muscles and control urinary incontinence.

Worked examples

Example 1 — a first encounter with Postpartum period

Start with the simplest possible case. Write down what Postpartum period claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Postpartum period before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Postpartum period ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Postpartum period

In research
Postpartum period appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Postpartum period in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Postpartum period is common in secondary-school and first-year university syllabi. It links to neighbouring topics Childbirth, Human pregnancy, Maternal health, so understanding it makes those chapters shorter.
In everyday life
Look for Postpartum period outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
