## Postpartum Hemorrhage Management
* Overview of clinical protocols, recognition, and emergency response.

## Defining PPH: ACOG vs. WHO
* ACOG: Cumulative blood loss ≥ 1,000 mL or signs of hypovolemia within 24 hours.
* Historical: ≥ 500 mL (vaginal) or ≥ 1,000 mL (cesarean).

## Etiology: The 4 T's
* Uterine Atony (Tone): 70-80% of cases.
* Trauma (Lacerations/Rupture): 20%.
* Tissue (Retained Placenta): 9%.
* Thrombin (Coagulopathies): 1%.

## Quantitative Blood Loss (QBL)
* Visual estimation underestimates by 30-50%.
* Protocol: Weigh all soaked materials (1g = 1mL).

## The Shock Index (SI) as Early Warning
* SI = Heart Rate ÷ Systolic BP.
* Pregnant normal range: 0.7-0.9.
* Severe/Transfuse threshold: > 1.1–1.4.

## Medical Management: Uterotonics
* **Oxytocin**: 10-40 units IV/IM (First Line).
* **Methylergonovine**: 0.2 mg IM; avoid in Hypertension.
* **Carboprost**: 250 mcg IM; avoid in Asthma.
* **Misoprostol**: 800-1000 mcg Rectal.

## Tranexamic Acid (TXA)
* Administer within 3 hours of birth.
* Dose: 1 gram IV over 10 minutes.

## Intrauterine Balloon Tamponade (UBT)
* Used when drugs fail.
* Inflate with 300-500mL sterile saline.

## Massive Transfusion Protocol (MTP)
* Ratio 1:1:1 (PRBCs, FFP, Platelets).
* Trigger: >1500mL QBL or vital sign instability.

## Surgical Escalation Ladder
1. Uterine Conservation (D&C, B-Lynch sutures).
2. Vascular Ligation (Uterine/Ovarian Arteries).
3. Hysterectomy (Definitive management).

## PPH Emergency Algorithm
* **Stage 1**: Massage, Oxytocin, TXA.
* **Stage 2**: Move to OR, UBT, start MTP.
* **Stage 3**: Surgical intervention, Hysterectomy.
