Puerperal sepsis is a bacterial infection of the genital tract occurring anytime between the rupture of membranes or labor and the 42nd day postpartum. It remains a leading cause of maternal mortality and morbidity in Nigeria, particularly in under-resourced settings where home deliveries without skilled birth attendants are common. Historically termed childbed fever, the condition is officially defined by the presence of a fever of 38 degrees Celsius or higher alongside pelvic pain, abnormal vaginal discharge, or delayed reduction in the size of the uterus. Early recognition is vital because the infection can escalate rapidly from localized endometritis to generalized peritonitis and septic shock.
Following childbirth, the placental site leaves a large, raw, vascular wound that is highly susceptible to bacterial invasion. Bacteria ascend from the lower genital tract or are introduced via contaminated instruments during examinations and delivery.
Several clinical and environmental factors increase a parturient woman's vulnerability to developing an ascending infection. Prolonged rupture of membranes exceeding 18 hours allows vaginal flora ample time to ascend into the uterine cavity. Multiple digital vaginal examinations during labor significantly raise microbial introduction rates. Cesarean section, particularly when performed as an emergency procedure, carries a much higher infection risk than spontaneous vaginal delivery due to surgical site exposure. Other contributing conditions include anemia, malnutrition, prolonged labor, retained placental tissue, and preexisting bacterial vaginosis or sexually transmitted infections.
The clinical picture of puerperal sepsis typically begins with a sudden temperature spike within the first few days after delivery. Patients frequently report lower abdominal pain and uterine tenderness upon palpation. The lochia may change significantly, turning profuse, purulent, and foul-smelling, though a lack of odor does not rule out severe non-streptococcal infection. Tachycardia often precedes measurable drops in blood pressure, serving as an early warning sign of developing sepsis. If the infection spreads, the uterus fails to undergo normal involution, remaining boggy and tender.
Confirming puerperal sepsis requires a combination of clinical assessment and targeted laboratory investigations. A complete blood count typically reveals marked leukocytosis with a shift to the left, indicating active bacterial infection. Cervical and high vaginal swabs should be collected for microscopy, culture, and sensitivity testing before initiating antibiotics, though treatment must never be delayed while awaiting results. Blood cultures are essential if the patient exhibits rigors or persistent high fevers to identify bacteremia. Pelvic ultrasound helps detect retained products of conception or pelvic abscesses that require surgical intervention.
Prompt administration of broad-spectrum intravenous antibiotics forms the cornerstone of medical management. Because polymicrobial infections are common, regimens typically combine drugs covering gram-positive, gram-negative, and anaerobic organisms, such as ampicillin, gentamicin, and metronidazole. Treatment is later adjusted based on laboratory culture and sensitivity reports. If retained placental tissue is identified, surgical evacuation using gentle curettage or vacuum aspiration must be performed under antibiotic cover. Supportive care involves aggressive fluid resuscitation, pain management, and close hemodynamic monitoring.
Comprehensive nursing care focuses on stabilizing vital signs and monitoring for signs of clinical deterioration. Nurses must accurately measure and record fluid intake and output, maintaining an indwelling urinary catheter when necessary to monitor renal perfusion. Regular temperature monitoring helps evaluate the efficacy of prescribed antimicrobial therapy. Nutritional support with high-protein and high-calorie diets aids tissue healing. Providing compassionate psychological support is equally critical, as severe illness disrupts maternal-infant bonding and causes significant anxiety for the new mother and her family.
Uncontrolled puerperal sepsis can progress to severe complications, including pelvic peritonitis, septic thrombophlebitis, septic shock, and long-term chronic pelvic pain or tubal factor infertility. Prevention relies heavily on antenatal health education, strict aseptic techniques during all vaginal examinations, and minimizing unnecessary operative interventions. Administration of prophylactic antibiotics during cesarean sections has drastically lowered infection rates. Ensuring clean delivery practices and immediate postpartum hygiene further safeguard maternal health.
