Optimal Nursing Care During the Third Stage of Labour

The third stage of labour begins immediately after your baby is born and ends when the placenta is completely delivered. While this stage typically lasts only 5 to 15 minutes, it is a critical period that requires careful nursing management to prevent life-threatening complications. During this time, nurses play a vital role in ensuring both mother and baby transition safely into the postpartum period.

Understanding the third stage of labour 🔗

After delivering your baby, the uterus continues to contract, causing the placenta to separate from the uterine wall. This natural process involves three distinct phases: the latent phase where strong contractions create a shearing force between the uterine wall and placenta, the detachment phase where separation gradually occurs, and finally the expulsion phase when the placenta is delivered. The median duration of this stage is approximately 6 minutes, though delivery within 30 minutes is considered normal.

Nurses monitor several key signs that indicate placental separation. The uterus changes from an elongated to a more spherical shape, the umbilical cord lengthens as the placenta moves down into the vagina, and a small gush of blood often appears. These classic indicators help the healthcare team determine when the placenta is ready to be delivered.

Active management approach 🔗

Most healthcare facilities now practice active management of the third stage of labour to prevent postpartum hemorrhage, which causes approximately 70,000 maternal deaths worldwide each year. Active management includes three key components that work together to reduce bleeding risk.

Administration of uterotonics 🔗

Oxytocin is the gold standard medication for preventing excessive bleeding during this stage. Prophylactic oxytocin reduces maternal blood loss and the need for additional medications when given immediately after delivery. Nurses typically administer 5 to 10 units through intravenous or intramuscular injection right after the baby’s birth, sometimes even before the placenta delivers.

Research shows that intravenous administration of oxytocin carries a lower risk for postpartum hemorrhage compared to intramuscular injection. The medication works by stimulating the uterine muscle to contract rhythmically, which helps constrict blood vessels and minimize bleeding from the placental site.

Controlled cord traction 🔗

Once the placenta has separated, controlled cord traction helps deliver it safely. The healthcare provider applies gentle, steady traction to the umbilical cord while placing the other hand above the pubic bone to provide counter-pressure and prevent uterine inversion. This technique must be performed carefully and only after clear signs of placental separation appear. Pulling too forcefully or too soon can cause serious complications.

Uterine massage after placental delivery 🔗

After the placenta is delivered, uterine massage promotes contraction and helps prevent hemorrhage. The nurse places one hand on the lower abdomen and uses firm, circular motions to stimulate the uterus to contract. This fundal massage should continue until the uterus feels firm like a grapefruit rather than soft and boggy.

Studies indicate that sustained uterine massage started immediately after placental delivery and repeated every 15 minutes for the first two hours significantly reduces blood loss. The technique involves gentle but firm pressure, and while some women find it uncomfortable, it serves an essential protective function.

Monitoring for complications 🔗

Nurses maintain vigilant observation during the third stage, checking vital signs every 15 minutes and assessing for any concerning changes. Blood pressure, pulse, respiratory rate, and oxygen saturation provide important clues about the mother’s condition.

Recognizing excessive bleeding 🔗

Normal blood loss during vaginal delivery ranges up to 500 mL, but losses exceeding this amount require immediate intervention. Postpartum hemorrhage is defined as blood loss of 1,000 mL or more, and it remains one of the leading causes of maternal mortality worldwide.

Rather than relying on visual estimates, which tend to be inaccurate, nurses now use quantitative measurement techniques. This involves collecting blood in calibrated drapes or weighing blood-soaked materials to get a precise measurement. Accurate blood loss tracking helps identify problems early when interventions are most effective.

Assessing uterine tone 🔗

The uterus should feel firm and well-contracted after placental delivery. A soft, boggy uterus indicates atony, the most common cause of postpartum hemorrhage. When the uterus fails to contract properly, blood vessels at the placental site remain open and continue bleeding. Nurses check uterine firmness frequently by palpating the fundus through the abdominal wall.

If the uterus feels soft, immediate uterine massage is performed while additional uterotonics may be administered. The nurse also ensures the bladder is empty, as a full bladder can prevent proper uterine contraction and increase bleeding risk.

Ensuring placental completeness 🔗

After delivery, the healthcare provider carefully inspects the placenta to verify that it is intact. Missing pieces of placental tissue can prevent the uterus from contracting effectively and lead to continued bleeding or infection. The placenta is examined for completeness of both the maternal and fetal surfaces, and all membranes should be accounted for.

If the placenta fails to deliver within 30 minutes, it is considered retained. This occurs in 1 to 3 percent of deliveries and increases the risk of hemorrhage. Manual removal may be necessary, which carries additional risks of infection and bleeding.

Supporting mother-baby bonding 🔗

While managing the medical aspects of the third stage, nurses also facilitate the crucial first moments between mother and baby. Immediate skin-to-skin contact provides numerous benefits: it helps regulate the newborn’s temperature, promotes bonding, and encourages successful breastfeeding.

Interestingly, skin-to-skin contact also supports the third stage of labour itself. When the baby is placed directly on the mother’s chest, it triggers the release of natural oxytocin, which helps the uterus contract and the placenta separate. This beautiful example of nature’s design shows how caring for the baby simultaneously helps protect the mother.

Additional nursing responsibilities 🔗

Throughout the third stage, nurses balance multiple priorities. They monitor the newborn’s transition to life outside the womb, assessing heart rate, respiratory effort, and temperature. They support the mother emotionally during this intense time of joy, exhaustion, and sometimes anxiety. They also prepare for potential complications by having emergency supplies readily available.

Pain management continues during this stage, as uterine contractions can cause moderate discomfort. Nurses offer both pharmacologic and non-pharmacologic comfort measures, helping mothers use breathing techniques and providing reassurance. Creating a calm, supportive environment allows families to begin bonding while ensuring safety.

When additional interventions are needed 🔗

If bleeding continues despite initial management, nurses escalate care rapidly. Additional uterotonic medications may include misoprostol, methylergonovine, or carboprost, each with specific uses and contraindications. In severe cases, procedures such as uterine packing, balloon tamponade, or surgical intervention may be necessary.

The healthcare team follows established protocols to respond quickly and systematically. Early recognition of abnormal bleeding, immediate intervention, and coordinated teamwork significantly improve outcomes and can be lifesaving.
