What Happens During Delivery

Childbirth is one of nature’s most powerful processes. When a baby is ready to arrive, the mother’s body begins a series of rhythmic muscle tightenings known as postpartum uterine contractions.

These contractions aren’t random — they’re the body’s way of helping the baby move through the birth canal and preparing the placenta to separate after delivery.
Each contraction pushes the baby closer to birth while helping the cervix open. The frequency, strength, and coordination of postpartum uterine contractions determine how smooth and safe the delivery will be.

What Are Postpartum Uterine Contractions

Postpartum uterine contractions are involuntary muscle movements of the uterus that occur during labor and continue after childbirth.
They serve three main purposes — dilating the cervix, helping the baby descend through the birth canal, and expelling the placenta.

A healthy contraction pattern usually starts mildly and becomes stronger, longer, and closer together as labor progresses. These contractions are essential for both childbirth and recovery.

The Stages of Labor Contractions

During labor, contraction patterns evolve with each stage.

In the first stage, contractions help the cervix thin out and open gradually. They begin mildly, often every 15–20 minutes, and become stronger as delivery nears.
In the second stage, contractions intensify every 2–3 minutes, pushing the baby through the birth canal. The mother feels strong pressure, signaling that the body is working naturally to bring new life into the world.
Even after the baby is born, postpartum uterine contractions continue, aiding in placenta expulsion and preventing excessive bleeding — marking the beginning of recovery.

What Happens Postpartum (After Delivery)

The postpartum phase— often called the fourth stage of labor — begins right after the placenta is delivered and lasts up to six weeks. It’s a crucial time for physical healing, hormonal changes, and emotional adjustment.

Key postpartum changes include:

  • Uterine involution: The uterus gradually returns to its pre-pregnancy size.

  • Lochia: A vaginal discharge that clears remaining blood and tissue.

  • Hormonal shifts: Estrogen and progesterone levels drop, while prolactin increases to support breastfeeding.

  • Emotional changes: Mothers may experience joy, bonding, fatigue, or mild baby blues.

Why Postpartum Uterine Contractions Matter

After delivery, postpartum uterine contractions play a vital role in preventing postpartum hemorrhage (PPH) — excessive bleeding that can occur after childbirth.

These contractions seal blood vessels that supplied the placenta, minimize bleeding, and help the uterus shrink back to normal size.
Many mothers experience these as “afterpains,” especially during breastfeeding, since oxytocin — the same hormone that triggers contractions during labor — is released during nursing.

When Contractions Weaken or Fail

Sometimes, the uterus fails to contract effectively after delivery, a condition called uterine atony.
It’s one of the leading causes of postpartum hemorrhage and requires immediate medical attention.

Common causes include:

  • Overstretched uterus due to twins or a large baby

  • Prolonged or extremely fast labor

  • Uterine exhaustion

  • Certain medications that relax uterine muscles

Without proper contraction, open blood vessels keep bleeding, posing serious risks to the mother’s health.

Medical Management of Weak Postpartum Uterine Contractions

Doctors manage weak or absent postpartum uterine contractions using uterotonic agents — medicines that help the uterus contract firmly and stop bleeding.

Common uterotonic medicines include:

  • Oxytocin: The first choice for stimulating uterine contractions.

  • Misoprostol: A prostaglandin analogue that enhances uterine tone.

  • Methylergometrine: Strengthens uterine muscles but should be used cautiously in hypertensive patients.

  • Carboprost Tromethamine (PGF₂α analogue): A strong prostaglandin used when other treatments fail, known for effectively inducing postpartum uterine contractions and controlling bleeding.

Role of Carboprost Injection in Postpartum Care

Carboprost Injection is one of the most trusted medical solutions for postpartum bleeding that doesn’t respond to oxytocin or ergot preparations.

How it works:
Carboprost (a synthetic prostaglandin F₂α) acts directly on uterine muscles, triggering strong contractions and compressing blood vessels to control bleeding.

Key benefits:

  • Rapid control of postpartum hemorrhage

  • Short onset of action

  • Effective even in uterine atony cases

  • Reduces the need for surgical interventions like hysterectomy

Available in 125 µg and 250 µg strengths, it’s used only in hospital settings under medical supervision.

Caring for the Mother Beyond Delivery

Postpartum recovery involves more than physical healing. Emotional and nutritional care are equally important.

Encourage hydration and iron-rich foods to recover from blood loss.
Support mental health through family involvement and open communication.
Promote rest, gentle movement, and postnatal check-ups to ensure healthy uterine recovery.

Every contraction, every heartbeat, and every act of care contributes to a mother’s healing journey.
