State the diagnose and define, identify the four risk factors, list 5 signs and symptoms, outline investigations, treatment and management, and discuss preventative measures for Mary's condition.

Step 1: State the diagnosis and explain. Diagnosis: Puerperal sepsis (postpartum sepsis). Explanation: The patient is a 30-year-old woman, 5 days postpartum after delivery of twins (one stillborn) with history of postpartum hemorrhage (PPH). She presents with fever of 38^C, abdominal pain, pulse 108 bpm (tachycardia), blood pressure 90/60 mmHg (hypotension), and respiratory rate 28 breaths/min (tachypnea). These vital signs indicate systemic infection and sepsis (SIRS criteria: temperature >38^C, heart rate >100 bpm, respiratory rate >20/min). Risk factors include recent delivery at a small health center (possibly limited hygiene/asepsis), multiple gestation, stillbirth, and PPH (leading to uterine atony, retained products of conception, or tissue trauma favoring bacterial infection). Step 2: List 5 signs and symptoms that may indicate the condition. Fever >38^C Lower abdominal pain or uterine tenderness Foul-smelling or purulent vaginal discharge (lochia) Chills or rigors Tachycardia (heart rate >100 bpm) Step 3: Presumptive treatment before transfer. a. IV fluids: Ringer's lactate or 0.9\% normal saline: initial bolus 20 ml/kg body weight over 1 hour, then 100-200 ml/hour maintenance (adjust based on response, monitor urine output >30 ml/hour). b. Antibiotics: (Broad-spectrum IV covering aerobic/anaerobic organisms per WHO guidelines) Ampicillin 2 g IV every 6 hours OR Ceftriaxone 1 g IV every 24 hours Gentamicin 5 mg/kg IV once daily Metronidazole 500 mg IV every 8 hours Step 4: List 3 danger signs which prompt referral. Persistent hypotension (systolic BP <90 mmHg) despite IV fluid bolus Altered mental status or confusion Severe respiratory distress (respiratory rate >30/min or difficulty breathing) puerperal sepsis
