Severe Dog Bite Injuries in Elderly Patients Require More Than Rabies Treatment
- A 73-year-old patient suffered more than ten bites, including an open fracture of the radius, after being attacked by a family dog.
- A 76-year-old bedridden patient sustained extensive skin and subcutaneous tissue separation across a 20 to 25 centimeter area on the forearm.
- Medical experts emphasize that animal bites require comprehensive surgical evaluation for vascular, bone, and soft tissue damage rather than routine superficial wound care.
Severe Mechanical Trauma and Open Fracture Presentation
The first case involves a 73-year-old patient from Hanoi admitted to the hospital after an unexpected attack by one of the family's two 20-kilogram dogs, which had recently given birth. Clinical examination revealed over ten separate bite wounds across the body, with approximately seven concentrated on the left arm, forearm, and hand, alongside large wounds on the right buttock and right knee. Notably, a deep bite to the forearm resulted in an open fracture of the radius. Dr. An noted that the injury involves severe soft tissue damage deep enough to cause an open bone fracture.
Attending physicians initiated rabies prophylaxis, administered antibiotics, and performed targeted wound care. Because the contaminated wounds carry a high infection risk, doctors refrained from immediate complete closure, instead opting for continuous monitoring, frequent dressing changes, and inflammation management. Animal bites introduce complex microbial pathogens deep into human tissue when a dog’s teeth breach the skin and crush underlying structures, transforming seemingly minor punctures into high-risk surgical emergencies.
Extensive Tissue Avulsion in Vulnerable Patients
The second case involves a 76-year-old bedridden patient named NTK, who had been paralyzed for approximately six years. Per Dr. Le Trung Thanh from the department of plastic, aesthetic, and interdisciplinary surgery, the patient was attacked while lying in bed, leaving him virtually defenseless. The biting and tearing force generated extensive skin damage on the left forearm. The entire skin layer and subcutaneous fat were pulled away from the underlying tissue, exposing the fascia and muscles across an area measuring 20 to 25 centimeters from the elbow nearly to the wrist, with a maximum width of approximately 10 centimeters.
Clinical management for this patient included initial emergency stabilization, thorough wound cleansing, and surgical debridement of damaged tissue. Following an initial week marked by significant swelling and localized erythema, medical teams planned subsequent staged cleansing and gradual suturing to reduce the wound surface area. Alongside surgical interventions, the patient received rabies prophylaxis protocols.
Clinical Protocol for Complex Animal Bites
Medical specialists stress that domestic animal bites must be assessed as significant traumatic injuries requiring rigorous evaluation for potential blood loss, shock risk, and structural compromise to blood vessels, nerves, and joints. The crushing and pulling mechanics of a dog’s jaw amplify trauma far beyond initial visual appearance. Consequently, early surgical treatment focuses on thorough wound irrigation, precise determination of structural damage, and careful staging of closure techniques, as severely contaminated or crushed wounds contraindicate immediate primary suturing.
Patients experiencing severe animal-related trauma or deep tissue injuries should seek immediate evaluation at specialized surgical centers or consult with orthopedic trauma and reconstructive surgery professionals to manage infection risks and preserve limb function.
