How to cauterize a rat's wound? - briefly
First, sterilize a fine‑tip cautery instrument and heat it until it glows red. Then press the hot tip onto the wound for a few seconds to achieve hemostasis, and finish by irrigating the area with an antiseptic solution.
How to cauterize a rat's wound? - in detail
Cauterization stops bleeding by applying heat directly to the tissue. The technique is used when a small rodent suffers a puncture or laceration that cannot be closed with sutures or adhesive.
Required tools
- Fine‑point electrocautery probe or a sterile, heated metal needle
- Adjustable power source with low‑wattage setting (5–10 W)
- Microscopic or magnifying lens for visual clarity
- Sterile gauze pads
- Antiseptic solution (e.g., diluted chlorhexidine)
- Protective gloves and eye shield
- Small container of sterile saline for irrigation
Preparation
- Restrain the animal securely but gently to prevent movement.
- Clean the wound with antiseptic; rinse with saline to remove debris.
- Dry the area with sterile gauze to improve heat transfer.
- Set the electrocautery unit to the lowest effective power; test on a non‑living surface to confirm temperature.
Procedure
- Position the heated tip perpendicular to the wound edge.
- Apply brief, controlled contact (1–2 seconds) to each bleeding point.
- Observe tissue response; stop when bleeding ceases and a small, white coagulum forms.
- Move to adjacent points if necessary, maintaining a short interval between applications to avoid excessive thermal damage.
- After each contact, irrigate with saline to dissipate heat and prevent carbonization.
Post‑cauterization care
- Cover the site with a sterile, non‑adhesive dressing.
- Monitor for signs of infection or necrosis over the next 24–48 hours.
- Provide analgesia appropriate for rodents if pain is evident.
