Endometritis is the inflammation of the endometrium, which is the inner mucous membrane lining of the uterus. This condition most commonly arises from ascending bacterial infections from the lower genital tract. In clinical practice across Nigerian healthcare facilities, postpartum endometritis remains one of the leading causes of maternal morbidity following delivery, particularly after prolonged rupture of membranes or caesarean sections. While it frequently presents acutely after childbirth or miscarriage, it can also manifest as a chronic condition linked to pelvic inflammatory disease or retained foreign bodies like intrauterine devices.
The development of endometritis depends heavily on microbial invasion and patient susceptibility. The normal vaginal flora can become pathogenic when introduced into the uterine cavity under specific favorable conditions.
Endometritis is broadly categorized into acute and chronic forms based on the duration of the inflammatory process and the type of immune cells involved.
| Feature | Acute Endometritis | Chronic Endometritis |
|---|---|---|
| Onset | Rapid, usually postpartum or postabortion | Insidious, lingering over weeks or months |
| Primary Cells | Neutrophils infiltrating the endometrial stroma | Plasma cells scattered within the stroma |
| Common Causes | Bacterial pathogens like *Streptococcus* or *Staphylococcus* | Persistent infections like *Chlamydia* or retained products |
| Symptoms | High fever, severe lower abdominal pain, purulent lochia | Abnormal uterine bleeding, mild pelvic discomfort, discharge |
In acute cases, bacteria breach the mucosal barrier, causing intense neutrophilic infiltration, edema, and microabscess formation. Chronic forms feature a persistent lymphocytic and plasma cell infiltrate, often altering the normal cyclic regeneration of the endometrial tissue.
Patients presenting with endometritis exhibit a constellation of signs that reflect localized pelvic infection and systemic inflammatory response. Nurses must recognize these clinical cues promptly during postpartum ward rounds.
Diagnosing endometritis combines thorough clinical assessment with laboratory investigations. Nurses play a crucial role in gathering baseline data and monitoring the patient's response to therapy.
A complete blood count typically reveals leukocytosis with a left shift, indicating an active bacterial infection. Endometrial biopsy is reserved for chronic cases to identify plasma cells under microscopy, while high vaginal or intrauterine swabs help isolate the specific causative organism for targeted antibiotic therapy. Pelvic ultrasonography is frequently ordered to rule out retained products of conception, which often mimic or perpetuate the infection.
During assessment, nurses systematically check vital signs every four hours, measure fundal height and consistency, and inspect the character, color, and odor of lochia or vaginal discharge.
Prompt antimicrobial therapy forms the cornerstone of endometritis treatment to prevent systemic complications like sepsis. Broad-spectrum intravenous antibiotics are initiated immediately while awaiting culture results. The classic combination regimen for postpartum endometritis includes clindamycin and gentamicin, which effectively cover both aerobic and anaerobic organisms commonly found in the female genital tract. Alternatively, broad-spectrum cephalosporins or extended-penicillins may be used.
In cases where retained products of conception are confirmed via ultrasound, surgical evacuation through vacuum aspiration or gentle curettage is performed alongside antibiotic coverage to clear the nidus of infection.
Comprehensive nursing care focuses on monitoring recovery, promoting comfort, and educating the patient on self-care and prevention.
When diagnosed and treated promptly, the prognosis for endometritis is generally excellent, with complete resolution of symptoms and preservation of reproductive health. However, delayed or inadequate treatment can lead to severe, life-threatening complications.
