Active Management of the Third Stage of Labour: How AMTSL Prevents Postpartum Haemorrhage

• The third stage of labour (birth of baby to delivery of the placenta) usually lasts 5-30 minutes and is the highest-risk period for heavy bleeding.
• Active management — a uterotonic like oxytocin within one minute of birth, gentle controlled cord traction, and uterine massage — cuts postpartum haemorrhage (PPH) by roughly 60-70 percent.
• PPH is the single leading cause of maternal death in India (about a quarter to a third of cases), and most of those deaths are preventable.
• AMTSL and delayed cord clamping are compatible — you can have both, benefiting mother and baby together.
• Heavy bleeding, large clots, dizziness, or a racing pulse in the hours and days after birth are red flags. Call your doctor or the 102 maternal ambulance immediately.

The third stage of labour begins the moment your baby is born and ends when the placenta is delivered. It usually lasts 5 to 30 minutes and is easy to overlook in the excitement of meeting your newborn. But this is exactly when the body has to switch off a large, open blood supply, so it deserves close medical attention.

What happens inside the womb. Once the baby is out, the uterus rapidly shrinks from baby-sized to roughly grapefruit-sized. This contraction peels the placenta off the uterine wall and clamps shut the blood vessels behind it. Signs that the placenta has separated include a small gush of blood, the cord visibly lengthening at the vaginal opening, and the uterus becoming firmer and rising higher in the abdomen. The placenta is then expelled with the next contraction.

Why bleeding is the danger. By full term, the vessels feeding the placenta carry around 500-700 ml of blood per minute. After separation, those vessels are open and will keep bleeding unless the uterus squeezes them shut by contracting. When the uterus stays soft and fails to contract — a condition called uterine atony, the most common cause of postpartum haemorrhage — blood loss can be rapid and severe. A woman can lose 500-1000 ml in minutes, and far more if it is not managed quickly.

Expectant vs active management. Historically, the third stage was managed expectantly: the team simply waited for the placenta to come away on its own. Modern practice is active management, which intervenes early to keep the uterus firm. The shift from expectant to active management is one of the biggest reasons maternal deaths from bleeding have fallen.

Active management also fits neatly with delayed cord clamping and skin-to-skin contact with your newborn — none of these need to be sacrificed for the others.

Active management has three parts, performed in sequence after birth. Together they work far better than any one part alone.

1. A uterotonic medicine. Within one minute of birth, the team gives a drug that makes the uterus contract. The global standard is oxytocin 10 IU injected into the thigh muscle. Carbetocin (a longer-acting oxytocin-like drug) is an alternative, especially at caesarean, and is heat-stable — useful where refrigeration is unreliable. Misoprostol tablets are a backup where injectable oxytocin is not available, and ergometrine combinations are used less often now because they can raise blood pressure.

2. Controlled cord traction (CCT). Once the placenta has separated, the team gently pulls on the cord with each contraction while the other hand steadies the uterus through the abdomen. Steadying the uterus prevents a rare but serious complication called uterine inversion. CCT speeds up delivery of the placenta and lowers the chance of a retained placenta. It is never done before the placenta has separated.

3. Uterine massage. After the placenta is out, the team firmly massages the top of the uterus through the abdomen to keep it contracted. This is repeated periodically over the first couple of hours.

Doses and routes at a glance:

The evidence behind active management is among the strongest in all of obstetrics. Large randomised trials and Cochrane systematic reviews consistently show that AMTSL reduces blood loss, severe haemorrhage, postpartum Anemia in Pregnancy in India: Cutoffs, IFA, Diet & Treatment, and the need for blood transfusion.

Compared with expectant management, active management roughly halves the risk of losing more than 500 ml of blood and significantly reduces the chance of needing a transfusion. The trade-offs are modest — a little more nausea or vomiting from the uterotonic, and a small rise in blood pressure with ergometrine-containing regimens — and the World Health Organization, FIGO, FOGSI, ACOG, and RCOG all recommend universal AMTSL for every vaginal birth.

Why this matters so much in India. India's maternal mortality ratio has fallen dramatically — from over 300 deaths per 100,000 live births in 1990 to under 100 in recent data — but that is still far higher than in high-income countries. Postpartum haemorrhage remains the single largest cause of maternal death here, roughly a quarter to a third of all cases. Most of these deaths are preventable with prompt, skilled care.

Cost is not the barrier. Under the Janani Shishu Suraksha Karyakram (JSSK), government facilities provide oxytocin and the other components of AMTSL free of charge, alongside free delivery, blood, ambulance transport, and food. Quality-improvement programmes such as LaQshya have built AMTSL into the standard for government labour rooms. The remaining challenge is consistent delivery of all three components everywhere, fast recognition when bleeding does occur, and reliable access to blood and surgery for severe cases.

Universal AMTSL prevents most haemorrhages, but some women need extra vigilance. Knowing the risk factors helps the team prepare.

Clinicians group the causes of PPH using the "4 Ts": Tone (a soft, non-contracting uterus — the cause of 70-80 percent of cases), Trauma (tears of the perineum, vagina, or cervix), Tissue (a retained placenta or accreta spectrum), and Thrombin (clotting problems).

Common risk factors include:

Spotting PPH early is the key to a good outcome. It is defined as more than 500 ml of blood loss after a vaginal birth, more than 1000 ml after a caesarean, or any bleeding that makes the mother unwell — whichever comes first.

Visual estimates are unreliable and usually underestimate true loss, so teams weigh blood-soaked pads and drapes (1 gram equals 1 ml) and use calibrated collection drapes.

Signs that bleeding is significant:

When PPH is recognised, the team acts on several fronts at once using a structured 'massive obstetric haemorrhage' protocol.

First steps. Call for senior help, alert the blood bank and theatre, lay the woman flat, give oxygen, secure two large IV lines, send blood for cross-matching and clotting tests, and start rapid IV fluids — all while finding the source of bleeding.

Stop the bleeding using the 4 Ts. For tone, the team massages the uterus, may compress it by hand, and gives extra uterotonics (an oxytocin infusion, methylergometrine — avoided if blood pressure is high, carboprost — avoided in asthma, or rectal misoprostol). Tranexamic acid 1 g into a vein is given early to reduce bleeding. For trauma, tears are stitched. For tissue, a retained placenta is removed. For thrombin, clotting is corrected with blood products.

Blood transfusion. Significant PPH often needs transfusion, using balanced amounts of red cells, plasma, and platelets. A facility's blood-bank capacity is critical — which is exactly why high-risk women are steered toward well-equipped hospitals.

If medicines aren't enough, surgical options include a balloon inside the uterus (a Bakri balloon, or an improvised condom catheter), compression sutures, tying off pelvic arteries, artery embolisation by interventional radiology, and — as a last, life-saving resort — hysterectomy. Severe cases may need intensive care afterwards.

Time matters. The faster bleeding is controlled, the better the outcome. Most deaths from PPH stem from delayed recognition, slow response, or limited facility resources — not from the bleeding being untreatable. This is why the prevent-and-respond combination of universal AMTSL plus rapid treatment is so powerful.

Many parents worry they must choose between active management for the mother and delayed cord clamping for the baby. You don't — they are fully compatible.

Delayed cord clamping (DCC) means waiting 1-3 minutes before cutting the cord so the baby receives extra blood from the placenta. This boosts the baby's iron stores for the first 4-6 months and improves the transition to breathing. WHO and FOGSI recommend it for all newborns who don't need immediate resuscitation.

Why they fit together. The mother's bleeding is controlled by the uterus contracting (driven by oxytocin), not by how quickly the cord is clamped. Research has shown that delaying cord clamping does not meaningfully increase the mother's blood loss. So the modern sequence is: baby is born → oxytocin given to the mother within one minute (this can happen while the cord is still pulsing) → wait 1-3 minutes → clamp and cut the cord → deliver the placenta with controlled cord traction → uterine massage.

At caesarean, DCC is also recommended for healthy babies, usually for 30-60 seconds, with the uterotonic given around the time of cord clamping.

When immediate clamping is right. If the baby needs urgent resuscitation, or the mother is bleeding heavily, the cord is clamped straight away. Otherwise, you can simply ask for both in your birth plan: "I'd like delayed cord clamping if mother and baby are well, combined with active management of the third stage."

Some births carry a higher PPH risk and need tailored third-stage care.

Postpartum haemorrhage is the leading cause of maternal death in India and worldwide, which is why the third stage gets so much clinical attention.

The numbers. India's maternal mortality ratio has fallen from over 300 per 100,000 live births in 1990 to under 100 in recent data — real progress, but still well above high-income countries. PPH accounts for roughly a quarter to a third of these deaths, the largest single — and most preventable — category.

Why these deaths are preventable. The tools work: AMTSL prevents most bleeding, and uterotonics, transfusion, and surgery can treat the rest. Most PPH deaths come from systemic gaps — no skilled birth attendant, no uterotonic at the moment of birth, delays in recognition or response, no blood bank nearby, or long transport times to a higher facility.

The system's response. JSSK removes the cost of delivery and emergency care; the Pradhan Mantri Surakshit Matritva Abhiyan (PMSMA) provides free specialist antenatal check-ups; and LaQshya upgrades government labour rooms. Maternal mortality varies sharply across India — Kerala is close to high-income levels while some states remain several times higher — reflecting differences in access and infrastructure.

What you can do. Engage with quality antenatal care, deliver at a facility matched to your risk level, have a transport plan for emergencies, and learn the postpartum warning signs. Your awareness — and your family's — is part of the safety net.

In the hours and days after birth, certain signs mean you need urgent medical care — at the hospital, your obstetrician, or by calling the 102 Janani Express maternal ambulance (free under JSSK) or 108 emergency ambulance. Do not wait to see if it settles.

Most women only learn about third-stage care while it is happening. A little knowledge beforehand helps you take part in shared decisions and spot trouble early.

Questions worth asking in antenatal visits: Does this hospital give a uterotonic like oxytocin to every mother after birth? Do you combine delayed cord clamping with active management? What is your protocol if heavy bleeding occurs? Clear answers are reassuring; hesitation is worth discussing.

What to expect at the birth. Soon after your baby arrives, you'll get an injection (usually oxytocin in the thigh). The team will deliver the placenta with gentle cord traction, then massage your uterus and watch you closely for a few hours.

Before you leave hospital, ask for written or verbal discharge advice on warning signs. Iron supplements are often continued for some weeks to help your haemoglobin recover, especially as postpartum anaemia is common. Make sure your partner or family also knows the danger signs — at home, they are often the first to notice. Use your postpartum recovery weeks and the 6-week check to raise any concerns about the birth or your recovery.
