Active Management of Third Stage of Labor Complete Guide for PPH Prevention
Below is a **concise yet complete, exam-oriented, SEO-friendly reference** on **Active Management of Third Stage of Labor (AMTSL)**, structured for **medical students, clinicians, and obstetric exams**.

# **Active Management of Third Stage of Labor (AMTSL)**
## **Definition**
**Active Management of the Third Stage of Labor (AMTSL)** is a **planned set of interventions** performed **immediately after the birth of the baby** to **facilitate placental delivery and prevent postpartum hemorrhage (PPH)**, the leading cause of maternal mortality worldwide.
---
## **Importance and Rationale**
* **Postpartum hemorrhage** accounts for a significant proportion of **maternal deaths**
* AMTSL **reduces blood loss**, **shortens third stage**, and **lowers risk of uterine atony**
* Recommended by **WHO, FIGO, ICM, and ACOG**
---
## **Components of AMTSL (Core Steps)**
### **1. Administration of a Uterotonic Drug (Most Important Step)**
* Given **within 1 minute after delivery of the baby**
* **After delivery of anterior shoulder or complete birth**
* **Before or after placental delivery** (as per guideline)
### **2. Controlled Cord Traction (CCT)**
* Gentle traction on umbilical cord
* Combined with **counter-traction on uterus**
* Performed **only after signs of placental separation**
### **3. Uterine Massage After Placental Delivery**
* Ensures **uterine contraction**
* Reduces risk of uterine atony
* Routine sustained massage **not recommended**, but **assessment of tone is essential**
---
## **Uterotonic Drugs Used in AMTSL**
### **Oxytocin (Drug of Choice)**
* **Dose:** 10 IU IM or slow IV
* **Onset:** 2–3 minutes
* **Advantages:** Highly effective, minimal side effects
* **Preferred by WHO**
### **Ergometrine / Methylergometrine**
* **Dose:** 0.2 mg IM/IV
* **Contraindications:** Hypertension, pre-eclampsia, heart disease
* Causes sustained uterine contraction
### **Oxytocin + Ergometrine (Syntometrine)**
* More effective but **higher side effects**
* Nausea, vomiting, hypertension
### **Misoprostol**
* **Dose:** 600 μg orally
* Used where injectables unavailable
* Side effects: Fever, shivering
---
## **Controlled Cord Traction (CCT): Key Points**
* Perform only when uterus is **well contracted**
* Look for **signs of placental separation**:
* Lengthening of cord
* Gush of blood
* Uterus becomes globular and rises
* Prevents **retained placenta**
* Reduces duration of third stage
---
## **Uterine Massage**
* After placenta delivery
* Assess uterine tone **every 15 minutes for first 2 hours**
* Continuous massage is **not routinely advised**
---
## **Timing of Cord Clamping**
* **Delayed cord clamping (1–3 minutes)** recommended
* Does **not interfere with AMTSL**
* Improves neonatal iron stores
---
## **Benefits of AMTSL**
* ↓ Postpartum hemorrhage by **50–70%**
* ↓ Severe blood loss (>1000 mL)
* ↓ Need for blood transfusion
* ↓ Duration of third stage
* ↓ Maternal morbidity and mortality

## **AMTSL vs Expectant Management**
| Feature | AMTSL | Expectant Management |
| ------------- | ------------------ | -------------------- |
| Uterotonic | Given routinely | Not given |
| Cord traction | Yes | No |
| Blood loss | Significantly less | More |
| Duration | Shorter | Longer |
| PPH risk | Low | High |
---
## **Indications**
* **All vaginal deliveries**
* Especially important in:
* Anemia
* Multiple pregnancy
* Prolonged labor
* Polyhydramnios
* Grand multiparity
---
## **Contraindications**
* No absolute contraindication
* Avoid **ergometrine** in:
* Hypertension
* Preeclampsia
* Cardiac disease
---
## **Complications (Rare)**
* Retained placenta (if CCT done improperly)
* Uterine inversion (improper traction)
* Drug side effects (ergometrine, misoprostol)
---
## **WHO Recommended AMTSL Protocol (Summary)**
1. **Oxytocin 10 IU IM/IV**
2. **Delayed cord clamping**
3. **Controlled cord traction**
4. **Assess uterine tone**
---
## **Key Exam Pearls**
* **Most important component:** Uterotonic administration
* **Drug of choice:** Oxytocin
* **Primary aim:** Prevention of postpartum hemorrhage
* **Third stage normal duration:** ≤ 30 minutes
---
## **Conclusion**
**Active Management of Third Stage of Labor** is a **simple, cost-effective, life-saving obstetric intervention**. Universal implementation of AMTSL significantly reduces **postpartum hemorrhage and maternal mortality**, making it a **standard of care in modern obstetrics**.
