Postpartum Hemorrhage (PPH): Recognition and Management
Written by Dr. Muhammad Salar Raza · Manually reviewed by Dr. Muhammad Salar Raza · Content updated
Clinical Pathway
Define PPH as blood loss of 500 mL or more after vaginal birth or 1000 mL or more after cesarean, or any loss causing hemodynamic instability. Call for help, establish large-bore intravenous access, send blood tests including crossmatch, and assess the 4 T's: tone, trauma, tissue, and thrombin. Uterine atony causes about 70% of cases and is treated immediately with bimanual uterine massage and oxytocin infusion. Escalate uterotonics as needed: carboprost (avoid in asthma), methylergonovine (avoid in hypertension), and misoprostol, and give tranexamic acid within 3 hours of birth. Persistent bleeding proceeds to intrauterine balloon tamponade, then surgical options including compression sutures, artery ligation or embolization, and hysterectomy as the last resort.
Clinical Reasoning
A boggy, enlarged uterus points to atony; a firm uterus with steady bright bleeding suggests genital tract trauma, and retained placenta or clotting failure explain the remainder. The order of uterotonics is constrained by comorbidity: methylergonovine is dangerous in hypertension and preeclampsia, and carboprost precipitates bronchospasm in asthma. Tranexamic acid reduces death from bleeding when given early, so do not delay it. Shock can develop late in young healthy women because of physiological compensation, so tachycardia and narrowing pulse pressure are earlier warnings than hypotension. Quantify blood loss rather than estimating visually, which consistently underestimates.
Sample MCQ
A 30-year-old woman has heavy vaginal bleeding immediately after a vaginal delivery. Her uterus is boggy and enlarged, blood pressure is 100/60 mmHg, and pulse is 110 beats per minute. What is the most appropriate first step?
- AUterine massage and intravenous oxytocin
- BImmediate hysterectomy
- CIntramuscular methylergonovine regardless of history
- DObservation for 1 hour to see if bleeding settles
Correct Answer: Uterine massage and intravenous oxytocin
A boggy uterus indicates atony, the commonest cause of PPH, and immediate uterine massage with oxytocin is the correct first response while help, access, and blood products are arranged. Hysterectomy is the definitive last resort after medical and tamponade measures fail, never the first step. Methylergonovine is a second-line uterotonic and must be avoided in hypertensive patients; it is not the automatic first drug and requires checking the history. Observation is dangerous: compensated young patients deteriorate abruptly, and early uterotonics plus tranexamic acid within 3 hours measurably reduce mortality.

Preeclampsia: Diagnosis and Management
Diagnose preeclampsia with new hypertension (140/90 mmHg or higher) after 20 weeks of gestation plus proteinuria or maternal organ dysfunction. Severe features include pressure of 160/110 mmHg or higher, severe headache, visual disturbance, epigastric pain, thrombocytopenia, renal impairment, or pulmonary edema. Severe preeclampsia mandates admission, magnesium sulfate for seizure prophylaxis, and antihypertensive therapy with labetalol, oral nifedipine, or hydralazine. The definitive treatment is delivery, timed by gestational age and severity: immediate stabilization then delivery at term or with severe features, and expectant management only in carefully selected preterm cases without severe features. Continue magnesium for 24 hours postpartum.
Chronic Hypertension: Diagnosis and Management
Chronic hypertension is a persistent and sustained elevation of blood pressure, typically defined as a systolic blood pressure greater than or equal to 130 mmHg or a diastolic blood pressure greater than or equal to 80 mmHg on multiple occasions. It is a major modifiable risk factor for various cardiovascular diseases, stroke, and kidney disease. Treatment for chronic hypertension involves a multi-faceted approach, starting with lifestyle modifications such as dietary changes (e.g., DASH diet), regular physical activity, weight loss, and reduced sodium and alcohol intake. Pharmacological therapy is often necessary and may include various classes of antihypertensive medications like diuretics, ACE inhibitors, angiotensin receptor blockers (ARBs), beta-blockers, and calcium channel blockers, frequently used in combination to achieve target blood pressure. Chronic hypertension is often referred to as 'the silent killer' because it is frequently asymptomatic for many years, even at high levels. When symptoms do occur, they are typically non-specific and may include headaches, dizziness, nosebleeds, or shortness of breath, usually manifesting in severe or long-standing cases or during a hypertensive crisis. Most diagnoses are made during routine medical screenings.
Gestational Diabetes Mellitus (GDM): Screening and Management
Screen all pregnant women at 24-28 weeks with a 75 g oral glucose tolerance test, or earlier when risk factors such as obesity or previous GDM exist. First-line management is medical nutrition therapy with structured physical activity and daily glucose self-monitoring. If fasting or postprandial targets are repeatedly exceeded despite lifestyle measures, start insulin, with metformin as an accepted alternative in many guidelines. Monitor fetal growth because GDM drives macrosomia, and plan delivery around 38-39 weeks when medication is required. After delivery, insulin needs fall sharply; arrange a 75 g OGTT at 6-12 weeks postpartum because about half of women with GDM later develop type 2 diabetes.
