Learning Outcomes
- Describe the physiological changes of the postpartum period.
- Identify critical elements of postpartum assessment and nursing care.
- Discuss safe and effective postpartum nursing care.
- Outline the critical elements of discharge teaching.
Nursing diagnoses: pain (uterine involution, perineal trauma, engorgement); risk for infection (perineum, mastitis); risk for fluid volume deficit from uterine atony; risk for impaired urinary elimination; risk for constipation; knowledge deficit about postbirth health promotion.
Expected outcomes: firm fundus with scant to moderate lochia; spontaneous void within 2 to 4 hours of birth; at least 10 glasses (80 oz) of fluid a day with a high-fiber diet; verbalizes warning signs and follow-up plan.
I. Overview
- Postpartum period: the 6 weeks after childbirth; the “fourth trimester”
- Maternal mortality: death from pregnancy complications up to 1 year postpartum. US rate rose from 16.9 (2016) to 17.3 (2017) per 100,000 live births, more than double the 1987 rate (7.2)
- Healthy People 2030 targets (Table 12-1): reduce maternal deaths to 15.7 per 100,000; increase exclusive breastfeeding through 6 months; increase postpartum depression screening; reduce unintended pregnancies and pregnancies within 18 months of a prior birth
- Screen for perinatal mood and anxiety disorders with a standardized tool such as the Edinburgh Postnatal Depression Scale (EPDS); screening alone does not improve outcomes without follow-up systems
Box 12-1, postpartum assessment overview: vital signs, pain, breath and heart sounds; labs (CBC, rubella, Rh status); vaccines (Tdap, influenza, pneumococcal, COVID-19); breasts; uterus; bladder; bowel; lochia; episiotomy, lacerations, perineum, hemorrhoids; lower extremities; emotions, bonding, fatigue, psychosocial factors.
II. Reproductive System
A. Uterus and involution
- Involution: return of the uterus to near prepregnant size, shape and location; takes 6 to 8 weeks. Happens through contractions, muscle atrophy and smaller uterine cells
- The contracted myometrium compresses open vessels at the placental site and limits blood loss
- Afterpains: cramping from contractions; more common in multiparas and with breastfeeding (suckling releases oxytocin); worse with each additional birth; usually ease after day 3. Primiparas usually have little cramping because the uterus stays contracted
- Afterpain comfort: void often (a full bladder worsens cramping), warm blanket on the abdomen, relaxation, ibuprofen or acetaminophen
Assessment frequency for fundus, VS, RR and temperature (same schedule for all):
- Every 15 minutes for the first hour
- Every 30 minutes for the second hour
- Every 4 hours for the next 22 hours
- Every shift after 24 hours, and more often if findings are abnormal
Hemorrhage timing:
- Greatest risk is in the first hour after birth
- Primary (early) PPH: within 24 hours
- Secondary (late) PPH: 24 hours to 12 weeks, most often days 7 to 14
Fundal assessment technique:
- Have her void first (a full bladder displaces the uterus and causes atony)
- Explain, give privacy, lay her flat and supine, remove the pad so lochia is checked at the same time
- Support the lower uterine segment with one hand just above the symphysis pubis (prevents uterine inversion)
- Palpate the fundus with the other hand; note position, tone and location
- Measure in fingerbreadths from the umbilicus: 1 fingerbreadth = 1 cm
Expected fundal findings:
- Immediately after birth: midway between umbilicus and symphysis, firm, midline; rises to the umbilicus within a few hours
- Within 12 hours: at the umbilicus or 1 cm above, firm, midline
- 24 hours: 1 cm below the umbilicus
- Descends 1 cm per day; not palpable by day 14
Deviations:
- Uterus deviated to the side (usually right), soft or above the umbilicus: full bladder. Immediate action is to help her void, then reassess; catheterize if she cannot void
- Subinvolution: uterus fails to descend as expected. Causes: retained placental fragments, infection, overdistended uterus (large baby). Leads to prolonged or excessive bleeding
Critical Component, uterine atony (boggy uterus):
- Most common cause of postpartum hemorrhage
- Boggy uterus means it is not contracted and bleeding risk is high
- Immediate action: massage the fundus with the palm in a circular motion until firm; reevaluate in 5 to 10 minutes
- No response to massage: give oxytocin per standing order and notify the provider
- Continued heavy bleeding with a FIRM fundus suggests a genital tract laceration or vulvar or vaginal hematoma
B. Endometrium and lochia
- Placental site heals by exfoliation (necrotic tissue sloughs and endometrium regenerates), which prevents scarring
- Lochia: discharge of RBCs, decidual tissue, epithelial cells and bacteria; a medium for bacterial growth
- Primary complication: metritis (endometrial infection; see Ch. 14)
Table 12-2, stages of lochia:
| Stage | Days | Expected | Abnormal |
|---|---|---|---|
| Rubra | 1-3 | Bloody, small clots, moderate to scant, fleshy odor; flow increases on standing or breastfeeding | Large clots, saturating a pad in 1 hour, foul odor, placental fragments |
| Serosa | 4-10 | Pink or brown, scant; flow increases with activity | Rubra continuing after day 4, heavy amount, foul odor |
| Alba | 10 on | Yellow to white, scant, fleshy odor | Bright red bleeding (possible late PPH), foul odor |
Amount (Fig. 12-3):
- Scant: under 1 inch on the pad (blood only on tissue when wiped, or a 1 to 2 inch stain)
- Light: under 4 inches
- Moderate: under 6 inches (text also says under 5 inches)
- Heavy: pad saturated within 1 hour
- Excessively heavy: pad saturated within 15 minutes
Clots and blood loss:
- Clots form when lochia pools in the lower uterine segment
- Note small clots in the chart; weigh any clot the size of an egg or larger and report it (large clots interfere with involution)
- 1 g of weight = 1 mL of blood loss
- Examine clots for tissue: retained placenta causes subinvolution and bleeding
Lochia teaching:
- Flow increases on rising in the morning or after sitting (pooling) and with heavy activity
- Report an increase in flow, a return to bright red after rubra ends, or a foul odor
- Change pads often, wash hands before and after, use a peri-bottle
- Teach her to check and massage her own fundus; secondary hemorrhage often happens after discharge. Causes: subinvolution, infection, retained tissue, von Willebrand disease
C. Clinical judgment: excessive bleeding
- PPH is the leading cause of US maternal mortality (10.7% of deaths, 2014-2017)
- Visual estimation (EBL) is inaccurate and delays treatment; use quantified blood loss (QBL) by weighing soaked items and clots (1 g = 1 mL). Scales and a PPH cart with algorithms belong in every unit
- Immediate actions: assess fundal position, tone and location; massage if boggy; if boggy and displaced, have her void (bladder scanner if available) and reassess; weigh all pads; notify the team; follow the hemorrhage staging algorithm if atony continues
Box 12-2, Maternal Early Warning Criteria (urgent bedside evaluation if a value persists, recurs, or comes with other abnormal values):
- Systolic BP under 90 or over 160
- Diastolic BP over 100
- Heart rate under 50 or over 120
- Respiratory rate under 10 or over 30
- SpO2 under 95% on room air
- Oliguria under 35 mL/hr for 2 hours or more
- Agitation, confusion or unresponsiveness
- Preeclampsia with a nonremitting headache or shortness of breath
While waiting for the clinician: secure free-flowing IV access, increase VS frequency, give oxygen, have a catheter, uterotonics and lab supplies at the bedside, consider a rapid response.
D. Vagina and perineum
Laceration degrees:
- First: vaginal mucosa and perineal skin
- Second: adds fascia of the perineal body
- Third: adds the rectal sphincter
- Fourth: extends through the rectal mucosa and lumen
- Midline episiotomy heals faster with less pain; mediolateral is cut at 45 degrees
Notes:
- Third- and fourth-degree lacerations, episiotomy and hemorrhoids may need a stool softener or laxative
- Primary complication is infection at the repair site
- Posterior tears cause bowel difficulty; anterior tears toward the urethra cause swelling and voiding difficulty
- Vaginal rugae return within 3 weeks
Assessment:
- Check the perineum with the fundus and lochia, then every shift using REEDA: redness, edema, ecchymosis, discharge, approximation
- Inspect anteriorly while supine, then side-lying with buttocks separated to see the perineum and check for hemorrhoids
- Expected: mild edema, minor bruising, edges approximated (most lacerations are internal), mild to moderate pain
Comfort and infection prevention:
- Ice or cold sitz bath for the first 24 to 48 hours (vasoconstriction reduces edema and numbs)
- Warm sitz baths after 24 hours, twice a day for 20 minutes (circulation and healing)
- Side-lying; tighten the gluteal muscles when sitting down
- Snug pads, topical anesthetics, analgesics; reassess pain 30 minutes after a dose
- Peri-bottle with warm water after every elimination; change pads often; wash hands
E. Pain management (Clinical Judgment)
- Sources: afterpains, perineal trauma, cesarean incision, nipple pain from poor latch, engorgement, hemorrhoids, general soreness
- Assess with VS, on complaint, before and after painful procedures and interventions. Culture shapes pain expression; number and faces scales may not work across cultures
- Nonpharmacological: ice packs, warm compresses, aromatherapy, sitz baths, repositioning, walking, showering, witch hazel pads, anesthetic spray
- Ibuprofen 400 to 600 mg PO every 4 to 6 hours PRN, max 3,200 mg/day; give with food or milk and a full glass of water. Hypersensitivity risk with asthma, nasal polyps or aspirin allergy
- Acetaminophen 650 mg every 4 hours PRN
- Opioids only for moderate to severe pain not relieved by the above; combine with a nonopioid and keep the course short (constipation, persistent use)
F. Breasts
- After birth, estrogen and progesterone fall and prolactin rises; prolactin drives milk production
- Suckling causes posterior pituitary release of oxytocin, which triggers let-down (milk ejection)
- Primary engorgement around day 3 in both breastfeeding and nonbreastfeeding women; breasts larger, firm, warm, tender, throbbing; subsides in 24 to 48 hours. Later engorgement comes from missed feedings or poor milk removal
- Colostrum: yellow; more protein and less carbohydrate than mature milk; contains IgG and IgA; lasts 5 days to 2 weeks before transition to mature milk
- Primary complication of breastfeeding: mastitis
Expected breast findings (both groups): day 1 soft and nontender; day 2 slightly firm and nontender; day 3 firm, tender and warm.
Box 12-3, breast care:
- Physiological engorgement: swollen breasts
- Pathological engorgement: hard, swollen, red, tender, warm, throbbing; may have a low fever; infant may not latch
- Breastfeeding treatment: frequent feedings to empty breasts; warm compresses and massage before feeding; pump or hand-express if the infant cannot nurse; ice packs after feeding; analgesics; supportive bra
- Nonbreastfeeding prevention and treatment: supportive bra (or sports bra) 24 hours a day until soft; avoid breast stimulation, expressing milk and heat (all stimulate production); ice packs; analgesics; subsides in 48 to 72 hours. Leakage, pain and engorgement may occur days 1 to 4
- Plugged ducts: pea-sized tender lumps from poor emptying; treat with frequent feeds, changing positions, warm compress or shower and massage before feeding. Unresolved, they can lead to mastitis and abscess
- Nipples: check before feeds for cracks, blisters and redness; air-dry after feeds; correct poor latch. Nipple soreness is a main reason women stop breastfeeding and breakdown is a portal for bacteria
Mastitis:
- Usually 3 to 4 weeks after birth
- Causes: bacteria through cracked nipples; milk stasis, engorgement, long intervals between feeds, stress, fatigue
- Signs: fever, chills, malaise, flu-like symptoms, UNILATERAL breast pain, redness and tenderness
- Treatment: empty the affected breast, antibiotics (milk culture may be ordered first), analgesia, rest, nutrition, fluids
- Continue breastfeeding or pumping; moist heat to the breast before feeding
III. Cardiovascular and Hematologic System
- Average vaginal blood loss 200 to 500 mL; tolerated because of pregnancy hypervolemia
- Stroke volume and cardiac output rise in the first hours as uteroplacental blood returns. CO stays elevated for 24 to 48 hours and is back to baseline by 10 days
- Plasma volume falls, then rises with fluid shifts; transient anemia resolves by 8 weeks
- WBC may rise to 30,000/mm3 within hours of birth (stress of labor) and normalizes within 7 days
- Clotting factors stay elevated and return to normal within 2 weeks: VTE risk, and PE is the life-threatening complication
- Orthostatic hypotension risk is highest in the first week (low pelvic vascular resistance)
- Postpartum chills (shaking in the first hours) come from vascular instability and are normal if the temperature is normal
Nursing actions:
- Pulse and BP on the standard schedule (q15 min x1 hr, q30 min x1 hr, q4h x22 hr, then every shift)
- Transient BP rise of about 5% is normal. Bradycardia is normal early postpartum. Tachycardia may mean blood loss, fever or infection
- Chills with a normal temperature: warm blanket and reassurance. Chills with fever: evaluate for infection and notify the provider
- Check calves and groin each shift for tenderness, edema and warmth; compare pulses; measure calf width if DVT is suspected. DVT signs: pain, tenderness, redness, warmth, a hard cord-like vessel, swelling
- Orthostatic precautions: rise slowly; assist with ambulation for the first 24 hours; sit or lie her down if dizzy; ammonia ampule if she faints
- Labs: Hgb drops 1 to 1.5 g/dL and Hct drops 3% to 4% per 500 mL blood loss
- Postpartum anemia: Hgb under 11 g/dL and Hct under 32%; treat with oral ferrous sulfate
- VTE prevention: early and frequent ambulation, no leg crossing, compression stockings if she has a history of clots
IV. Respiratory System
- Chest wall compliance returns once diaphragm pressure is relieved; back to baseline by the end of the postpartum period
- RR on the standard schedule; normal 12 to 20/min; SpO2 95% or higher; breath sounds clear
- Pulmonary edema risk: oxytocin, large IV fluid volumes, tocolytics (magnesium sulfate, terbutaline), multiple birth, infection, preeclampsia, bedrest
V. Immune System
- Immune suppression of pregnancy resolves
- Mild temperature elevation in the first 24 hours is common (exertion, exhaustion, dehydration, hormones)
- Under 100.4 F (38 C) in the first 24 hours: push fluids (8 to 10 glasses, at least 64 oz/day), rest, reassess in 1 hour
- 100.4 F (38 C) or higher on two occasions after the first 24 hours suggests infection: notify the provider, anticipate workup, and notify the nursery
- Postpartum vaccines: rubella (MMR) if nonimmune, Tdap, hepatitis B, varicella, influenza
Rubella immunization:
- First-trimester rubella has a 90% transmission rate; fetal effects include deafness, blindness, heart defects and intellectual disability
- Give to rubella-nonimmune women before discharge (consent may be required); MMR is often used
- Avoid pregnancy for 4 weeks after the vaccine
Rh isoimmunization:
- An Rh-negative woman exposed to Rh-positive blood (transfusion or an Rh-positive fetus) makes IgG anti-D, which crosses the placenta and hemolyzes fetal RBCs. It is preventable
- Rho(D) immune globulin is given at 28 weeks
- Postpartum: if the baby is Rh positive and the mother is Coombs negative, give a second dose within 72 hours of birth
- RhoGAM 300 mcg IM only, or Rhophylac 300 mcg IV or IM; do not confuse the IM and IV products
- Confirm mother Rh negative and infant Rh positive before giving
VI. Urinary System
- Transient stress incontinence may last up to 6 weeks; risk factors include multiparity, perineal trauma, large infant, long second stage, pushing technique
- Primary complications: bladder distention and cystitis
- Causes of distention and retention: IV fluids, anesthesia or analgesia (reduced urge), urethral edema, lacerations or episiotomy, operative delivery, bladder trauma
- Diuresis starts within 12 hours of birth (falling estrogen); output may reach 3,000 mL/day
Nursing actions:
- Help her void within 2 to 4 hours of birth; expect at least 300 mL per void
- Voids under 150 mL: palpate for distention (urinary retention). Signs: uterine atony, uterus above the umbilicus and to the right, increased lochia, suprapubic fullness. Bladder scan if available
- Cannot void with an overdistended bladder: catheterize. Indwelling catheter for 24 hours if the cause is edema; straight cath if little edema and repeat caths are not expected
- Peppermint oil on a cotton ball in the collection hat relaxes the urinary sphincter
- Frequency, urgency or burning suggests cystitis: notify the provider
- Fluids at least 10 glasses a day
- Cystitis: frequency, urgency, burning, suprapubic tenderness, hematuria, malaise; treat with antibiotics, fluids, rest
- Evidence-based practice: about one-third of women have incontinence in the first 3 months. Pelvic floor muscle training (Kegels): 8 contractions with 8-second holds, 3 times a day, 3 days a week, for at least 3 months
VII. Endocrine System
- Estrogen, progesterone and prolactin fall after placental delivery; estrogen starts rising after week 1
- Nonlactating women: prolactin declines over 3 weeks; menses returns at 7 to 9 weeks; first cycle usually anovulatory; ovulation returns at about 10 weeks on average
- Lactating women: suckling raises prolactin and suppresses menses; ovulation returns at about 17 weeks on average
- Ovulation can precede the first period, so both groups need contraception when intercourse resumes. Breastfeeding is not reliable contraception
- Diaphoresis: night sweats in the first weeks from falling estrogen, excreting pregnancy fluid. Check temperature to rule out infection; cotton nightwear; teach her to tell sweating from fever
VIII. Muscular and Nervous Systems
- Diastasis recti abdominis: separation of the rectus muscles, felt during fundal checks; reassure that it lessens over time
- Muscle soreness from positioning and pushing: ice for 15 minutes, heat, warm shower, analgesia
- Epidural or spinal: reduced lower-body sensation for several hours; delay or assist ambulation until full sensation returns (fall risk)
- Headache: assess location and quality. A post-dural puncture headache from CSF leak is worse upright and better lying flat. Headache can also signal preeclampsia; notify the provider for either
- Fatigue: promote rest, nap when the baby sleeps, cluster care, treat pain
IX. Gastrointestinal System
- GI tone and motility return to normal by the end of week 2; bowel function usually returns in 2 to 3 days
- Constipation risks: progesterone, inactivity, dehydration, fear of a BM after perineal trauma, perineal pain
- Hemorrhoids: common; witch hazel pads, topical anesthetics, sitz baths, side-lying instead of prolonged sitting
- Appetite: very hungry; regular diet unless otherwise ordered; snacks between meals
- Weight loss: about 11 to 12 lb at birth plus 5 to 8 lb from diuresis; on average about 3 lb above prepregnancy weight at 6 months
Nursing actions:
- Assess bowel sounds each shift; report faint or absent sounds (risk of obstruction)
- Ask about BMs; offer water and prune juice; fluids of 3,000 mL/day; fiber; ambulation; stool softener or laxative as ordered
- Ask about nausea and vomiting (common with opioids)
- Respect cultural food preferences; families may bring food from home
X. Follow-Up Care and Discharge Teaching
- See the maternal care provider within the first 3 weeks, with a comprehensive visit by 4 to 6 weeks (about 40% of women miss the postpartum visit)
- Comprehensive visit: physical, social and psychological assessment; EPDS depression screen; birth spacing and contraception (including LARC); vaccines; pain, incontinence, dyspareunia, fatigue, mood and feeding concerns
- Breastfeeding women need 500 to 1,000 extra calories a day and about 2 to 3 L of fluid
- Spread teaching over the whole stay rather than leaving it to discharge day
AWHONN POST-BIRTH warning signs:
- Call 911: chest pain; obstructed breathing or shortness of breath; seizures; thoughts of hurting herself or the baby
- Call the provider: bleeding that soaks one pad an hour or a clot the size of an egg; an incision that is not healing; a red, swollen, warm or painful leg; temperature 100.4 F (38 C) or higher; a headache that does not improve with medicine, or a bad headache with vision changes
- If the provider cannot be reached, go to the emergency room
Signs to report and what they mean:
- Heavy lochia (a pad an hour), a return to bright red bleeding, or egg-size clots: secondary PPH
- Foul-smelling lochia, fever, pelvic or abdominal pain: infection
- Frequency, urgency, burning: cystitis
- Unilateral breast tenderness with a warm red area, chills and fever: mastitis (3 to 4 weeks)
- Blurry vision, severe headache, epigastric pain, fluid retention: preeclampsia
- Leg pain, swelling and redness: DVT. Chest pain and dyspnea: PE
- Thoughts of harm, trouble caring for self or infant, sleep problems, persistent sadness: postpartum depression
Other teaching:
- Self-care: perineal care and pad changes until lochia stops; breast care; pain control
- Expected changes: involution, afterpains, lochia, engorgement, diaphoresis, diuresis, weight loss
- Nutrition: MyPlate; iron-rich foods for anemia (leafy greens, beans, red meat, poultry, fortified cereal, raisins); roughage for constipation
- Activity: at least 150 minutes a week of moderate activity such as brisk walking, in bouts of at least 10 minutes; Kegel exercises
- Rest: nap when the baby naps, prioritize, take vitamins, iron and pain medication as ordered
- Sexual activity: resume when lochia has stopped, the perineum has healed and she feels ready; lubricant for dryness; use contraception
- Smoking: most women who quit for pregnancy relapse after birth; encourage abstinence, offer resources, no smoking around the infant
- Schedule the postpartum visit before discharge

- Tachycardia is an early sign of hemorrhage; BP drops late
- Fever after the first 24 hours: notify the provider and the nursery
- Unilateral calf pain, warmth or swelling: DVT; sudden dyspnea or chest pain: PE (call 911)
- First ambulation: assist (orthostatic hypotension, epidural); if she faints, lay her down
- Postural headache after an epidural: post-dural puncture headache; headache with vision changes or epigastric pain: preeclampsia
- Confirm Rh status of mother and infant before RhoGAM; never give RhoGAM IV
