Comprehensive Study Notes on the Postpartum Period

Overview of the Postpartum Period

• Definition & Terminology:

  • The postpartum period is also termed the puerperium period.
  • Popularly referred to as the "fourth trimester of pregnancy".
  • Encompasses the 6-week period ($1\frac{1}{2}$ months) immediately following childbirth.
  • Divided into timeframes:
  • Immediate postpartum period: First 4 to 6 hours after birth (also designated as the 4th stage of labor).
  • Entire postpartum period: Extends through the 6th week following birth.

• Core Objectives of Postpartum Care / Protecting Women's Health:

  • Preserve future child-bearing function (ensuring the ability to become pregnant again and endure labor).
  • Ensure physical wellness so the mother can incorporate her new child into the family and provide adequate infant care.

• Nature of Maternal Changes:

  • Maternal postpartal changes are categorized as either retrogressive or progressive.
  • Retrogressive changes: Return of the maternal body to its pre-pregnancy state (may bumabalik na dati).
  • Progressive changes: Development of new postpartal functions and roles (bagong darating).

• Historical Context:

  • Historically, postpartum women were hospitalized for 5 to 7 days after childbirth and moved in a passive manner from one stage of recovery to the next.

Maternal Psychological and Behavioral Adaptation (Phases of the Puerperium)

1. Taking-In Phase

• Timeframe: Spans the first 2 to 3 days post-birth.
• Behavioral Characteristics:
  • Characterized by reflection, dependency, and a passive attitude.
  • The mother holds her child with a sense of wonder.
  • Time during which new parents review their pregnancy, labor, and birth experience.
• Maternal Challenges:
  • Physical discomfort.
  • Uncertainty regarding newborn care.
  • Extreme exhaustion following childbirth.
• Nursing Actions & Physiological Goals:
  • Assist the mother in regaining physical strength.
  • Help calm her thoughts.
  • Encourage her to talk about and process the birth experience.

2. Taking-Hold Phase

• Behavioral Characteristics:
  • The woman begins to initiate action independently and demonstrates strong interest in caring for her baby.
  • A time of renewed action and forward movement for the mother and the family.
  • The mother may feel insecure or anxious regarding her ability to properly care for her newborn.
• Variations in Onset:
  • Women who give birth without anesthesia may reach this second phase within a matter of hours after birth.
• Nursing Interventions:
  • Provide praise, positive reinforcement, and practical guidance to build maternal confidence.

3. Letting-Go Phase

• Behavioral Characteristics:
  • The woman finally redefines her role as a mother.
  • Fully accepts her new identity and role.
  • Extends and continues throughout the child's growing years.

Maternal Concerns and Psychological Spectrum

Normal Psychological Reactions

• Abandonment:
  • Feeling less important after giving birth, as attention shifts predominantly to the newborn.
  • Can be expected due to rapid postpartal hormonal changes.
  • Nursing Diagnoses:
  • Anxiety related to feelings of abandonment.
  • Risk for impaired parenting related to inadequate bonding behavior after childbirth.
• Disappointment:
  • Occurs when the baby's characteristics or sex do not match parental expectations.
  • Nursing Diagnosis:
  • Risk for impaired parenting related to disappointment in the sex of the child.

Postpartal Mood and Psychiatric Disorders

• Nursing Diagnosis for Postpartal Psychiatric Complications:
  • Risk for injury / Goal: No injury to mother or child.

Physiologic Retrogressive Changes

Postpartal retrogressive alterations are divided into reproductive system changes and systemic changes.

Reproductive System Changes

1. Uterus (Uterine Involution)

• Involution Process:

  • Involution is the process whereby reproductive organs return to their nonpregnant state over a matter of weeks.
  • Two main objectives:
  1. The area where the placenta was implanted is sealed off to prevent hemorrhage.
  2. The uterus is reduced to its approximate pregestational size.
  • If involution does not occur, the woman remains in danger of severe hemorrhage from the denuded uterine surface.

• Uterine Weight Progression:

  • Immediately after birth: Weighs approximately $1000\,\text{g}$.
  • End of 1st week: Weighs approximately $500\,\text{g}$.
  • Completion of involution (6 weeks): Weighs approximately $50\,\text{g}$ (equivalent to prepregnancy weight).

• Fundal Height & Position:

  • Decreases by 1 fingerbreadth (1 cm) per day from delivery until about day 8 to 10.
  • Day 1 postpartum: Palpable 1 fingerbreadth below the umbilicus.
  • Day 2 postpartum: Palpable 2 fingerbreadths below the umbilicus, continuing sequentially.
  • Days 10 to 14: The uterine outline is no longer palpable abdominally (receded behind the symphysis pubis).
  • Days 25 to 30: Uterus is grossly normal.
  • Day 45: Endometrium is fully repaired.

• Assessment of Uterine Consistency:

  • Firm / Well-Contracted: Feels firm and can be compared to a grapefruit in both size and tenseness.
  • Boggy / Soft / Flabby (malambot): Indicates uterine relaxation or uterine atony, meaning the uterus is not contracting properly, creating a high risk for postpartal hemorrhage.
  • Clinical routine involves checking fundal height and consistency.

• Afterpains:

  • Intermittent uterine contractions after birth cause cramping termed afterpains, similar to menstrual cramps.
  • Caused by contraction of the uterine muscle fibers.

• Nursing Diagnoses:

  • Risk for deficient fluid volume related to postpartal hemorrhage.
  • Acute pain related to uterine cramping.

2. Lochia (Uterine Discharge)

• Formation:
  • Separation of the placenta and fetal membranes occurs in the spongy layer or outer portion of the decidua basalis.
  • The remaining decidua differentiates into two layers:
  1. Inner layer: Serves as the foundation from which a new layer of endometrium is formed.
  2. Adjacent layer: Becomes necrotic and is cast off as lochia (uterine discharge).

• Types and Characteristics of Lochia:

• Lochia rubra:

  • Color: Red.
  • Postpartal Days: Days 1 to 3.
  • Composition: Blood, fragments of decidua, mucus, small blood clots.

• Lochia serosa:

  • Color: Pink / Pinkish-brown.
  • Postpartal Days: Days 3 to 10.
  • Composition: Blood, mucus, invading leukocytes.

• Lochia alba:

  • Color: White / Creamy.

  • Postpartal Days: Days 10 to 14 (may last up to 6 weeks until the placenta site is completely sealed off).

  • Composition: Largely mucus; high leukocyte count.

  • Clinical Monitoring & Checks:

• Odor: Should have a normal fleshy odor; foul odor indicates infection.

• Amount: Saturation of a perineal pad in 15 minutes or less is abnormal and indicates postpartal hemorrhage.

• Expected quantity should be monitored relative to normal menstrual flow volume.

• Nursing Diagnosis:

  • Risk for uterine infection related to lochia and denuded uterine surface.

3. Cervix

• Post-Birth State: Immediately following birth, the cervix is soft and malleable.
• Healing: Cervical contraction begins immediately, forming new muscle cells.
• By Day 7 Postpartum:
  1. Cervix feels firm and nongravid again.
  2. Internal os closes completely.
  3. External os remains slightly open and appears slitlike or star-shaped (transverse slit), whereas in a nulliparous woman it was round.

4. Vagina

• Post-Birth State: Soft, possesses few rugae, and has a larger diameter.
• Recovery: Takes the entire postpartal period to gradually return to its approximate prepregnancy state.
• Lactation Effect: Breastfeeding women may continue to have a thin-walled and fragile vaginal epithelium due to low estrogen levels.
• Interventions:
  • Practice Kegel exercises to restore vaginal strength, muscle tone, and pelvic floor integrity.
  • Coitus: Sexual intercourse can be safely resumed when lochia reaches the lochia alba stage and perineal healing is adequate.
• Nursing Diagnosis:
  • Risk for ineffective sexuality patterns related to physiologic changes of postpartal period.

5. Perineum

• Assessment Framework (REEDA):

  • R - Redness
  • E - Erythema
  • E - Ecchymosis
  • D - Discharge
  • A - Approximation of the edges

• Episiotomy & Lacerations:

• Episiotomy Incisions:

  • Median incision: Pros = heals immediately; Cons = tissue layer is thin, high risk of extending into the anal sphincter or rectum.
  • Mediolateral incision: Pros = safer relative to rectal involvement; Cons = thicker tissue (makapal), takes longer to heal.

• Laceration Degrees:

  • 1st Degree: Vaginal mucosa torn.

  • 2nd Degree: Perineal muscles torn.

  • 3rd Degree: Anal sphincter torn.

  • 4th Degree: Rectal mucosa / rectum torn.

  • Perineal Care Interventions:

• Cold Compress / Ice Pack: Applied during the first 24 hours post-birth to promote vasoconstriction and reduce edema/numbness.

• Hot Compress / Peri-Light / Sitz Bath: Applied after the first 24 hours to promote vasodilation and tissue healing.

  • Position: Dorsal recumbent.

  • Distance: 12 to 18 inches away.

  • Duration: 15 minutes.

  • Nursing Diagnoses:

• Impaired skin integrity related to perineal laceration.

• Risk for infection related to perineal sutures.

Systemic Changes

1. Hormonal System

• Human Chorionic Gonadotropin (HCG) & Human Placental Lactogen (HPL): Drop rapidly; levels become almost negligible by 24 hours post-delivery.
• Estrogen: Decreases with placental delivery; returns to prepregnancy levels within 1 to 2 weeks in non-lactating women.
• Follicle-Stimulating Hormone (FSH): Remains low for approximately 12 days, then begins to rise as a new menstrual cycle is initiated.

2. Urinary System

• Diuresis & Diaphoresis: Extensive postpartal diuresis and diaphoresis begin after birth to eliminate excess body fluid accumulated during pregnancy.
• Bladder Tone: Transient loss of bladder tone occurs (exacerbated if anesthesia/epidural was administered), making voiding difficult.
• Ureters: Dilation of ureters that occurred during pregnancy persists for 4 weeks postpartum.
• Clinical Parameters:
  • The mother must be able to void spontaneously within 6 to 8 hours after birth.
  • Assess for elevated risk of urinary tract infection (UTI) due to urinary stasis.
• Nursing Diagnosis:
  • Risk for impaired urinary elimination related to loss of bladder sensation after childbirth.

3. Circulatory System & Vital Signs

• Blood Volume & Blood Loss:

  • Blood volume returns to nonpregnancy levels by the 1st or 2nd week post-delivery.
  • Normal blood loss limits:
  • Vaginal birth: $300\text{--}500\,\text{mL}$.
  • Cesarean section: $500\text{--}1000\,\text{mL}$.

• Hematology:

  • As fluid is excreted, hematocrit and hemoglobin levels temporarily decrease, reaching prepregnancy levels by the 6th week.
  • Leukocytes (white blood cells) and fibrinogen levels remain elevated post-birth (protective mechanism against infection and hemorrhage).

• Thrombophlebitis Risk:

  • High fibrinogen levels produce a hypercoagulable state, increasing the risk of thrombus formation and vessel inflammation (thrombophlebitis).
  • Homan's Sign Assessment: Performed by dorsiflexing the patient's foot.
  • Positive Homan's Sign: Calf pain upon dorsiflexion, indicating potential deep vein thrombosis (DVT) / thrombophlebitis.

• Vital Signs Parameters:

  • Temperature:
  • May show a slight increase in the first 24 hours (up to $38^\circ\text{C}$ or $100.4^\circ\text{F}$) due to dehydration during labor.
  • On the 2nd or 3rd day postpartum, milk production and breast vascularity increase, which may cause a transient rise in temperature.
  • Pulse:
  • Increased stroke volume slows the resting pulse to 60 to 70 beats per minute (bpm) (puerperal bradycardia).
  • As diuresis diminishes blood volume, pulse returns to normal by the 1st week.
  • Clinical alert: A rapid, thready pulse is a sign of hemorrhage.
  • Blood Pressure:
  • Must remain stable at baseline.
  • Decreased BP: Indicates hemorrhage.
  • Increased BP: Indicates postpartal pregnancy-induced hypertension.
  • Oxytocin Administration: Can cause increased BP; withhold administration if BP is elevated.

• Nursing Diagnosis:

  • Risk for ineffective peripheral tissue perfusion related to thrombus formation.

4. Gastrointestinal System

• Appetite & Motility:
  • Digestion and absorption become active rapidly; the mother feels hungry and thirsty immediately.
  • Bowel sounds are active, but passage of stool is slow due to residual relaxin hormone.
• Defecation Parameters:
  • Hemorrhoids may be present from pushing during labor.
  • Bowel evacuation may be difficult or delayed due to slow peristalsis, painful sutures, or hemorrhoids.
  • Patient must be able to defecate within 24 hours to 3 days postpartum.
• Nursing Management:
  • Increase fluid intake, encourage early ambulation, and provide high-fiber foods.
• Nursing Diagnosis:
  • Risk for constipation related to slow bowel peristalsis after childbirth.

5. Integumentary & Musculoskeletal System

• Skin Changes:

  • Striae gravidarum: Reddened and prominent initially; fade to a pale white over 3 to 6 months.
  • Chloasma & Linea nigra: Fade by the 6th week as pregnancy hormones decline.
  • Skin Inspection: Always assess mucous membranes and nail beds for paleness (anemia/hemorrhage), cyanosis, or redness.

• Abdominal Wall & Ligaments:

  • Stretched abdominal wall muscles and uterine ligaments require a full 6 weeks to return to their former state.

• Weight Loss Breakdown:

  • Immediate loss of $10\text{--}12\,\text{lbs}$ (infant, placenta, amniotic fluid).
  • Additional loss of $5\,\text{lbs}$ due to postpartal diuresis and diaphoresis.
  • Total early postpartal weight loss equals approximately $18\text{--}19\,\text{lbs}$.

• General Effects of Retrogressive Changes (Nursing Diagnoses):

  • Disturbed sleep pattern related to exhaustion from and excitement of childbirth.
  • Risk for hygiene self-care deficit related to exhaustion from childbirth.

Progressive Postpartal Changes

Progressive changes represent the initiation of new physiological functions following birth:

1. Lactation
2. Return of Menstrual Flow
3. New Parenting Role

1. Lactation

• Hormonal Physiology:

  • During pregnancy, elevated estrogen and progesterone stimulate milk gland growth, increasing breast size. Thin, watery colostrum is formed.
  • Following delivery of the placenta, the sharp drop in estrogen and progesterone stimulates prolactin production from the anterior pituitary, initiating breast milk synthesis.
  • Infant sucking on the nipple triggers oxytocin release from the posterior pituitary, causing the let-down reflex (milk ejection) and uterine muscle contractions.

• Postpartal Breast Progression:

  • Days 1 to 2: Minimal change from pregnancy state; secretes thin, watery colostrum (rich in immunoglobulins).
  • Day 3: True milk forms within breast ducts. Breasts become engorged (look full, large, reddened, and feel tense or tender).

• Clinical Considerations:
  • Engorgement subsides as the infant sucks effectively and empties the breast.
  • Mastitis: Inflammation of breast tissue that can occur in breastfeeding mothers.
• Nursing Diagnosis:
  • Acute pain related to primary breast engorgement.

2. Return of Menstrual Flow

• Mechanism:
  • Expulsion of the placenta terminates placental estrogen and progesterone production.
  • Decreased hormone levels stimulate pituitary production of FSH, initiating ovulation and return of menses.
• Timelines:
  • Non-breastfeeding mothers: Menstrual flow returns in 6 to 10 weeks post-birth.
  • Breastfeeding mothers: Menstrual flow is delayed for 3 to 4 months (lactational amenorrhea), or in some women, for the entire duration of lactation.

3. Adaptation to the New Parenting Role

• Transitioning to infant care and expanding family dynamics.
• Nursing Diagnoses:
  • Health-seeking behaviors related to care of newborn.
  • Fear related to lack of preparation for child care.
  • Imbalanced nutrition, less than body requirements, related to lack of knowledge about postpartal needs.

Comprehensive Postpartal Assessment Framework: BUBBLESHE

• B - Breasts: Assess for engorgement, nipple integrity, and sucking effectiveness.
• U - Uterus: Assess fundal height, position, and firmness (involution progress).
• B - Bladder: Assess voiding frequency, volume, and bladder distension.
• B - Bowel: Assess bowel sounds, passage of flatus, and stool evacuation.
• L - Lochia: Assess color, amount, odor, and presence of clots.
• E - Episiotomy / Laceration: Assess REEDA signs and suture approximation.
• S - Skin / Striae: Assess striae, perineal skin integrity, and mucosal color.
• H - Homan's Sign: Assess for calf pain on dorsiflexion (DVT/thrombophlebitis).
• E - Emotional Status: Assess bonding, postpartal blues, and psychological adaptation.

Postpartal Discharge Education & Health Teaching

1. Work, Rest, and Exercise: Emphasize rest periods to prevent exhaustion; encourage gradual resumption of light activity and daily Kegel exercises.
2. Hygiene: Instruct on proper perineal hygiene (front-to-back wiping, warm water rinses) to prevent infection.
3. Coitus: Sexual intercourse may safely resume when lochia turns to lochia alba and perineal discomfort has resolved.
4. Contraception: Discuss appropriate family planning options suited for postpartum and breastfeeding status.
5. Nutrition & Breastfeeding: Educate on high-fiber diets, adequate fluid intake, and optimal breastfeeding positioning/latch.
6. Follow-Up: Schedule routine postpartal clinical evaluations.
