Anaesthesia in rabbits: understanding the risks, and how we minimise them
Is Rabbit Anaesthesia Riskier than Dog or Cat Anaesthesia?
Rabbit anaesthesia carries a slightly higher risk than anaesthesia in dogs and cats, due to rabbits’ unique anatomy, physiology, and sensitivity to stress. However, with an experienced rabbit veterinarian, these risks are significantly reduced. At our hospital, we use advanced monitoring and tailored support to keep your rabbit safe.
A 2025 study reported an anaesthesia fatality rate of between 1.39% and 4.8%. In contrast, dogs and cats had a fatality rate of 0.1%–0.2%. Several factors affect risk: your rabbit’s health status, the complexity of surgery, how we manage their airway, the anaesthetic drugs we use, and their breed or size.
Before proceeding with anaesthesia, your vet will assess whether the benefits outweigh the risks. In some cases, we may recommend hospitalisation or delay the procedure to stabilise your rabbit first.
What Makes Anaesthesia Risky?
Several factors increase the risk of anaesthesia in rabbits:
- Age: Very young and old rabbits may process drugs differently and lose body heat more easily.
- Breed: Rabbits like Netherland Dwarfs have short faces and small airways, making breathing support more challenging.
- Weight: Rabbits under 1 kg are harder to intubate and keep warm. Overweight rabbits can struggle with breathing under anaesthesia.
- Illness: Rabbits that are unwell may have organ issues that complicate anaesthesia
- Procedure complexity: Long or complex surgeries mean more time under anaesthesia, increasing risk.
- Stress: Stress can lead to decreased appetite and gut stasis, especially after surgery.
How we Reduce the Risks at The Wild Vet
Before the Procedure
Minimising Stress
We provide a calm, predator-free environment and use fear-free handling. Familiar items, like a favourite blanket or a bonded companion, are encouraged to reduce stress.
Pre-Anaesthetic Assessment
We perform a full physical exam before any procedure. This includes checking heart and lung function, temperature, hydration, and weight, and assessing signs of illness. This helps us create the safest anaesthetic plan.
Pre-Anaesthetic Assessment
We recommend blood tests to check liver and kidney function, red and white blood cell counts, and electrolyte levels. These give insight into how your rabbit might respond to anaesthetic drugs and guide our approach.
Premedication
Before anaesthesia, we give medications that calm your rabbit and provide pain relief. These drugs allow for a smoother and safer anaesthetic and recovery.
Pre-Oxygenation
Your rabbit is placed in a warmed oxygen chamber before induction. This helps fill their lungs with oxygen and lowers the risk of low body temperature after surgery.
Intravenous (IV) Catheter Placement
We place a small catheter in a vein (ear or leg) to deliver fluids and emergency drugs quickly if needed. This helps keep your rabbit hydrated and stabilised.
During the Procedure
Airway Access
This involves placing a soft tube into your rabbit’s windpipe (trachea) to maintain an open airway. It ensures your rabbit can breathe properly under anaesthesia and allows us to deliver oxygen and anaesthetic gases directly. It also helps prevent inhalation of saliva or stomach contents.
Heart and Respiratory Rate Monitoring
We constantly monitor your rabbit’s heart rate, and breathing rate, as a sudden change can signal problems such as pain, inadequate depth of anaesthesia, low oxygen levels, or cardiovascular compromise. If anything changes, we adjust our care immediately.
Blood Pressure Monitoring
We use specialised equipment to monitor your rabbit’s blood pressure during anaesthesia. Maintaining stable blood pressure is vital to ensure that organs are receiving enough blood and oxygen.
Blood Pressure Monitoring
We use specialised equipment to monitor your rabbit’s blood pressure during anaesthesia. Maintaining stable blood pressure is vital to ensure that organs are receiving enough blood and oxygen.
Capnography
This measures carbon dioxide levels in each breath, helping us track how well your rabbit is breathing. It helps detect issues such as shallow breathing or an airway blockage early.
Temperature Control
Rabbits can easily become cold under anaesthesia, which can slow recovery and affect organ function. We continuously monitor body temperature and use active warming devices like heated mats and warm air blowers to keep your rabbit comfortable.
Pulse Oximetry
This tool measures the oxygen levels in your rabbit’s blood and gives us a reading of their heart rate. It helps ensure that your rabbit is getting enough oxygen throughout the procedure.
Electrocardiogram (ECG)
An ECG monitors your rabbit’s heart rhythm and electrical activity during anaesthesia. It allows us to detect abnormal rhythms or signs of stress on the heart early.
Experienced Team
Every rabbit anaesthetic is managed by a vet and a nurse, who both have extensive rabbit experience. Our team is trained to recognise subtle changes during their procedure, and act quickly to rectify them.
Emergency Drugs
Before any procedure, we calculate the correct doses of emergency drugs and keep them within easy reach. In the rare event of a complication or cardiac arrest, this preparation allows us to respond without delay.
After the Procedure
Reversing Sedatives
If recovery is slow, we give medications to reverse the sedatives (where possible). This helps your rabbit wake up gently and safely. Reversing sedatives when appropriate can help stabilise vital signs, encourage earlier return to normal eating and grooming behaviours, and lower the risk of post-anaesthetic complications.
Postoperative Monitoring
Once your rabbit’s procedure is complete, an experienced rabbit nurse remains with them throughout recovery from anaesthesia. They are monitored closely for breathing patterns, heart rate, temperature, and signs of pain or distress until they are fully awake.
Assist Feeding
Once your rabbit is awake and alert enough, we begin assist feeding with a syringe. This ensures that their digestive system stays active, which is vital to prevent gastrointestinal stasis (gut stasis). Prompt feeding also helps maintain energy levels and promotes a quicker return to normal eating.
Pain Relief, Pain Relief, Pain Relief!
Good pain relief is essential for a smooth recovery. It reduces stress, supports healing, and helps prevent gut stasis. We provide pain relief before, during, and after surgery.
All rabbits receive pain relief as part of their premedication, and if your rabbit undergoes a procedure likely to cause discomfort, we provide additional pain relief tailored to their needs. This may include keeping them in hospital longer for additional pain relief injections or intravenous infusions, using local anaesthesia during surgery, and sending them home with additional pain medication.
