Puerperium

Summary

The puerperium, lasting about six weeks, is the period during which the maternal body returns to its pre-pregnancy state. Key changes include uterine involution, lochia discharge, cervical closure, diuresis, and establishment of lactation, alongside transient symptoms like mild fever, afterpains, and mood changes. Potential complications include infection, subinvolution, hemorrhage, breast disorders, and thromboembolism. Postpartum care focuses on monitoring recovery, supporting breastfeeding, managing pain, and detecting complications early.

Definition

The puerperium is the postpartum period lasting approximately six weeks after delivery, during which the reproductive organs and maternal physiology gradually return to their pre-pregnancy state. While most systemic changes resolve within six weeks, renal and cardiovascular adjustments may take up to 12 weeks.

Normal Postpartum Changes

General

• Low-grade fever, shivering, and leukocytosis are common during the first 24 hours postpartum and usually benign.

• Weight loss: immediate loss of 6 kg from the baby, placenta, and amniotic fluid, followed by 2–7 kg from lochia, diuresis, and uterine involution.
  
  

Uterine Involution

• Begins immediately after placental delivery; uterus contracts to compress venous sinuses and prevent hemorrhage.

• Fundal height decreases by ~1 fingerbreadth/day, becoming nonpalpable by 2 weeks and returning to ~100 g by 6–8 weeks.

• Afterpains (cramping) are common, more pronounced with breastfeeding due to oxytocin release.

• Subinvolution occurs when involution is delayed (e.g., retained products, infection, fibroids)

Lochia

Postpartum vaginal discharge from sloughing of decidua and cervical mucus:

• Lochia rubra: blood-tinged, days 1–4.

• Lochia serosa: brown-red to pink, watery, lasts 2–3 weeks.

• Lochia alba: yellow-white, up to 6–8 weeks.
  Persistent rubra suggests retained placenta; foul odor indicates infection.
  
  

Cervix & Vagina

• Cervix closes by 2 weeks postpartum.

• Vaginal tone gradually improves but may remain laxer than pre-pregnancy.
  
  

Urinary System

• Transient urinary retention may occur after prolonged labor, perineal trauma, or regional anesthesia.

• Diuresis is common in the first 48 hours.

• Ureters and renal pelvis return to normal by 6–12 weeks.
  
  

Gastrointestinal System

• Constipation and hemorrhoids are frequent; managed with hydration, stool softeners, and sitz baths.
  
  

Cardiovascular & Hematologic

• Plasma volume, cardiac output, and blood constituents normalize within 8–10 weeks.

• Increased risk of venous thromboembolism (VTE) during puerperium due to persistent hypercoagulability.
  
  

Breast Changes & Lactation

• Colostrum produced in the first 2–3 days, replaced by mature milk by day 3–5.

• Breast engorgement is common; managed with frequent emptying, supportive bras, and analgesia.

• Lactation suppresses ovulation temporarily, but contraception is recommended after 3 months.

• Combined estrogen–progestin contraceptives should be avoided in breastfeeding women.

Psychological & Emotional Adaptations

• Postnatal blues: affect up to 75%, presenting with mood swings, irritability, and tearfulness on days 2–10; self-limiting, requiring reassurance.

• Postpartum depression: affects 5–15%; occurs after the 3rd week with persistent low mood, insomnia, and impaired bonding. Managed with psychotherapy and, if needed, SSRIs.

• Postpartum psychosis: rare but severe, requiring urgent psychiatric care.

Postpartum Complications

Puerperal Fever

• Defined as temperature ≥38 °C on any 2 of the first 10 days (excluding first 24 hours).

• Causes: genital tract infections (most common), breast disorders, urinary tract infection, thrombophlebitis, respiratory infections.
  
  

Puerperal Sepsis

• Infection of the genital tract, commonly polymicrobial (anaerobic streptococci, staphylococci, Gram-negative bacilli).

• Risk factors: retained placenta, prolonged rupture of membranes, anemia, diabetes, operative deliveries.

• Clinical features: fever, uterine tenderness, foul lochia, subinvolution.

• Management: IV broad-spectrum antibiotics (penicillin, gentamicin, clindamycin), uterine evacuation if retained products, supportive care.
  
  

Breast Disorders

• Engorgement: swollen, painful breasts; managed with expression, supportive bra, NSAIDs.

• Nipple fissures: painful cracks due to poor positioning; risk of infection.

• Mastitis: usually due to Staphylococcus aureus, presents with fever, localized erythema, and pain; treated with antibiotics and continued milk expression.

• Breast abscess: requires incision and drainage plus antibiotics.

Postpartum Care

• Visit schedule: initial contact within 3 weeks; comprehensive evaluation within 12 weeks; more frequent visits if complications or risk factors.

• Components: assessment of involution, lochia, wound healing, breastfeeding support, psychological screening, contraception counseling, and VTE risk evaluation.

• Breastfeeding contraindications: HIV, active tuberculosis, use of certain drugs (e.g., street drugs, alcohol, cytotoxic medications). Hepatitis B and C are not absolute contraindications if newborn immunization is provided.
