🐄 Field Case Study: Severe Post-Dystocia Vulvar Necrosis with Myiasis
A cattle was presented with a history of dystocia that was improperly handled at field level. Due to lack of timely veterinary intervention, the condition progressed severely.
🔴 Clinical Findings:
- Severe damage to vulvar lips
- Extensive fibrosis and necrosis
- Heavy maggot infestation (myiasis)
- Foul-smelling discharge
- Accumulation of pus ventral to vulvar region
- Animal showing discomfort and straining
This is a classic example of how mishandled obstetrical cases can turn into life-threatening surgical conditions.

🩺 Clinical Diagnosis:
- Post-dystocia traumatic vulvitis
- Complicated with necrosis + myiasis + abscess formation
---
⚙️ Treatment Protocol (Field Surgical Management):
✔ 1. Surgical Debridement
- Complete removal of necrotic and fibrotic vulvar tissue
- Thorough cleaning of affected area
✔ 2. Abscess Drainage
- Incision at dependent pus pocket
- Proper drainage and flushing
✔ 3. Maggot Control
- Application of turpentine oil / maggoticidal agents
- Followed by topical dressing
---
💊 Medical Management:
🔹 Antibiotics (Long-acting)
- Oxytetracycline: 20 mg/kg IM (single dose, repeat after 72 hrs if needed)
🔹 NSAIDs (Pain & Inflammation)
- Flunixin meglumine: 1.1–2.2 mg/kg IV/IM
OR
- Meloxicam: 0.5 mg/kg SC
🔹 Anti-inflammatory (SAIDs if indicated)
- Dexamethasone: 0.04–0.1 mg/kg IM (use cautiously)
---
🧴 Topical Therapy:
- Magnesium sulfate (to reduce swelling and draw pus)
- Antibiotic ointment (Mycitracin) for wound healing
- Daily antiseptic dressing (povidone iodine)
---
⚠️ Clinical Insight:
Delay in treatment converted a manageable dystocia into:
➡️ Tissue necrosis
➡️ Myiasis
➡️ Secondary infection
Early intervention could have prevented surgical trauma and economic loss.
📈 Outcome (Expected):
With proper debridement, drainage, and antibiotics:
- Gradual healing within 2–3 weeks
- Fibrosis
