What to Expect When Your Pet Needs Anaesthesia

<h1>What to Expect When Your Pet Needs Anaesthesia</h1>

From someone who lives and breathes this work, and never forgets who’s on the table.

You’re sitting in the consult room, listening carefully as your vet walks you through what’s ahead. Maybe it’s a procedure you’ve known about for a while. Maybe it’s come up more suddenly. Either way, your pet needs surgery, and even if you trust your vet completely, there’s still that quiet worry sitting under your ribs.

Not just about the surgery itself but also what it means for them to be away from you. Unconscious. Vulnerable. Unable to tell anyone if something feels wrong.

It’s a big thing to hand that over.

And if you’re feeling that weight, whether it’s a soft concern or something stronger, you’re not alone.

As a veterinary anaesthesia specialist, I see that moment often. The pause, the breath, the worry behind the questions. I feel it too, because I’ve lived it as a pet owner. The truth is that anaesthesia asks for something big: your trust. Quietly placed in someone else’s hands, when your animal can’t speak for themselves.

And if it were my dog, my cat, my rabbit?
I’d want to know if someone was holding that responsibility with both hands.

What anaesthesia really involves (That no one tells you)

Anaesthesia isn’t just about putting them to sleep. It’s an intricate process, a living, changing puzzle, where everything from heart rate to blood pressure to breathing, temperature, and pain response is measured, interpreted, and carefully adjusted in real time.

It’s not passive or background. It’s active, attentive care, from when they drift off to when they return to you.

And when I say care, I mean it in the truest sense, not just competence but presence, focus, and vigilance. Knowing when things are just slightly off, even before a machine says so, is like reading between the lines of biology and staying ahead of discomfort before it becomes dangerous.

What makes specialist anaesthesia different?

In many clinics, the vet doing the surgery also manages the anaesthesia, and in healthy pets having short, simple procedures, that might be perfectly adequate.

But if your pet is older, has medical conditions, or if the procedure is longer or more complex, that’s where things start to shift.

I don’t perform surgery. I don’t split focus. I’m not called away to other cases or relying on a nurse to watch the monitor while I pop out.

Anaesthesia is all I do. And it’s everything I watch.

When I join your pet’s care team, I bring hospital-grade equipment, decades of specialist training, and one-to-one attention directly into your regular clinic, where your pet already feels safe. There’s no need to transport them to a big, unfamiliar hospital. You stay with your trusted vet. I join quietly, respectfully, and bring another layer of protection to the room.

“Good anaesthesia doesn’t begin in theatre. It begins in the quiet planning before anyone even touches a needle.”

On the day: What to expect

If we’ve had a pre-anaesthetic consultation, which I always recommend, I’ll already know your pet’s medical history, previous anaesthetic experiences, medications, quirks, and breed-specific considerations. We’ll discuss the risks, the plan, and what matters most to you.

When I arrive at the clinic, I bring more than equipment. I bring focus.

While your vet concentrates on the procedure, I’m tuned in to your pet – every breath, every temperature shift, every blip on the ECG. I bring advanced tools like capnography, anaesthetic gas monitoring, invasive blood pressure measurement, point-of-care ultrasound, spirometry, and real-time blood oxygen analysis. Still, the true work lies in knowing how to interpret what’s happening before it becomes problematic.

Anaesthesia isn’t static. It’s not a “set-and-forget” button. It’s a dance, and I never stop listening to the rhythm.
And when the surgery is finished?

That’s not when my job ends. That’s often when the real work begins.

Pet under monitor

Let’s talk about recovery (Because it matters more than most realise)

You might assume the riskiest part is the surgery itself, but many complications, such as when pets wake up, happen after the procedure. Hypothermia, airway blockages, irregular heartbeats, disorientation… these things don’t wait until you’re ready for them.

That’s why I stay. I don’t hand your pet over. I don’t walk away when the last stitch is placed.

I’m still there, reading every breath, checking reflexes, supporting their temperature, keeping them calm as they come back into their body.

I wait until they breathe independently, holding their temperature, aware enough to blink at the world. Only then do I step back.
“We don’t delegate recovery monitoring. I remain present until they’re warm, aware, breathing clearly, and back in their body.”

Home recovery: What’s worth watching, and what’s not

Most pets recover quietly and smoothly after specialist-led anaesthesia.

You might notice they’re sleepy for the rest of the day, which is perfectly expected. Some animals shiver or occasionally moan as they shift position, especially in the first few hours. It’s not pain, it’s the body rebooting after a big physiological event.

They may not be hungry for a meal, and that’s okay, too. A skipped dinner after anaesthesia is no cause for panic. A slight pinkness near where the catheter was placed is also common, like the mark your arm gets after a blood test.

But if your pet seems confused well into the next day, is panting excessively, refusing multiple meals, seems wobbly on their feet, or if anything feels wrong in your gut, that’s when you pick up the phone. I’d rather you call and be reassured than worry alone.

You know your animal better than anyone. Don’t dismiss that inner knowing.

Why i do this work (And why it matters)

Because this isn’t just “another procedure.”

This is your old girl who still lights up when you grab the lead, even if her hips aren’t what they used to be.
The anxious little rescue who finally started sleeping on the couch instead of the floor.
This is the one who picked you and has trusted you every day since.
They deserve not just to be “put under” but truly cared for in the space where they can’t speak for themselves.

And when you choose The Anaesthesia Vet, that’s what you’re choosing:

  • A specialist with over two decades of anaesthesia-only experience, not general surgery, not juggling other duties
  • Uninterrupted, one-on-one monitoring from the first sleepy blink to full, stable recovery
  • Hospital-grade equipment, brought to your regular vet’s clinic, so your pet stays in familiar hands
  • A tailored plan that accounts for every unique variable, from breed to medication to past medical history
  • Communication that’s clear, grounded, and respectful of both you and your vet
  • And above all, a person who shows up with heart, because this work still matters to me, every time

FAQs

Is anaesthesia safe for senior dogs and cats in Brisbane?

Yes, anaesthesia can be safely managed for older pets when it’s carefully planned and monitored by someone with specialist training. We tailor every approach to your pet’s age, health history and specific risks, using advanced equipment and personalised protocols in trusted local clinics across Brisbane, the Gold Coast and Sunshine Coast.

Does my pet really need a specialist for anaesthesia or can my regular vet handle it?

Your vet absolutely remains central to your pet’s care. We support them by managing anaesthesia for high-risk, complex or senior patients, bringing specialist-level monitoring and calm, focused oversight into the clinic you already trust. This extra layer of care helps reduce risk and improve recovery, especially for pets with additional health considerations.

Where will my pet’s anaesthesia take place, do I have to go to a hospital?

There’s no need to visit a separate hospital. We bring our mobile specialist service directly into local partnered clinics across Brisbane, the Sunshine Coast and Gold Coast. Your pet stays in familiar hands, surrounded by a team they already know, while we work quietly alongside your regular vet to provide specialist-level care.

If my pet needs urgent anaesthesia, can it be managed locally?

If your pet needs anaesthesia urgently, we’ll help assess what’s safest based on their condition, procedure, and available facilities. In some situations, it may be best for your pet to be transferred to a trusted specialist hospital we work with across Brisbane, the Gold Coast, or the Sunshine Coast. We’ll always prioritise the setting that offers the right level of support, and we’re happy to guide that decision with your vet.

Who stays with my pet during anaesthesia and recovery?

Your pet receives one-on-one specialist care from start to finish, from induction through to full recovery. There are no handovers or gaps in monitoring. We remain present until your pet is warm, stable, breathing clearly and neurologically responsive.

My dog is a bulldog, is anaesthesia more risky for flat-faced breeds?

Brachycephalic breeds like bulldogs and pugs require special protocols and experienced monitoring, due to their airway structure and breathing challenges. We routinely manage anaesthesia for flat-faced pets across Brisbane and Southeast QLD, using modified techniques to keep them safe and comfortable.

How is anaesthesia different when it’s managed by a veterinary specialist?

A veterinary anaesthesia specialist focuses exclusively on anaesthesia, pain control and recovery. While your vet concentrates on the surgery, we monitor your pet’s vital signs second by second, using advanced equipment and expert interpretation to guide every decision. This level of focus helps prevent complications before they arise.

What kind of monitoring does my pet receive during anaesthesia?

We use hospital-grade monitoring including ECG, blood pressure, capnography, temperature support and blood gas analysis, tailored to your pet’s needs. This allows us to respond to even the most subtle physiological changes, not just the obvious ones.

What should I expect after my pet wakes up from anaesthesia?

Mild drowsiness, quiet behaviour or a skipped meal are normal after anaesthesia. Your pet will be closely monitored until they’re stable and alert, and you’ll be given clear instructions for at-home recovery. If anything feels off, we encourage you to reach out, you know your pet best.

“I cannot recommend Dr Kieren Maddern highly enough. She has cared for both of my tiny, health-compromised Pomeranians, who are high risk when it comes to anaesthesia. As a very anxious owner, the thought of putting them under is always stressful, but knowing Dr Kieren is in control makes all the difference.”
