Anaesthesia for Hip and Knee Surgery

Anaesthesia for Joint Replacement – What Patients Need to Know

Before your joint replacement procedure, A/Prof Kaushik Hazratwala — a leading Townsville orthopaedic surgeon — will discuss anaesthesia options with you. The choice of anaesthesia is an important decision that can significantly influence your comfort, safety, and recovery. As an experienced Orthopaedic surgeon Townsville, A/Prof Hazratwala works closely with highly trained anaesthetists to ensure your anaesthesia plan is tailored to your health, preferences, and the type of Townsville hip and knee surgery you are undergoing.

Several factors influence the selection of anaesthesia:

Your past experiences and preferences

• Previous anaesthesia exposure
• Any reactions or complications
• Family history of anaesthetic issues

Your current health

• Smoking status
• Weight and fitness
• Other medical conditions beyond your hip replacement in Townsville or knee replacement in Townsville

Medication reactions

• Allergies
• Adverse drug reactions
• Current medications, supplements, vitamins, or herbal remedies

Risks

Risks vary depending on your health and the type of anaesthesia selected. Your surgeon and anaesthetist will discuss specific risks such as breathing difficulties, allergic reactions, or nerve injury.

Your healthcare team

The skills and preferences of your surgical and anaesthesia team play a major role in determining the safest and most effective anaesthetic approach.

Types of Anaesthesia

Anaesthesia falls into three broad categories: local, regional, and general.

---

Local Anaesthesia

Local anaesthesia numbs only the specific area being treated. Patients remain awake, and the effect lasts for a short period. For major procedures such as hip replacement in Townsville, knee replacement in Townsville, or robotic hip and knee replacement, local anaesthesia is used to complement regional or general anaesthesia.

A/Prof Hazratwala routinely uses High‑Volume Local Anaesthetic Infiltration in the peri‑articular tissues. This mixture includes:

• Naropin (local anaesthetic)
• Ketorolac (anti‑inflammatory)
• Celestone (steroid)
• Adrenaline
• Vancomycin (antibiotic)

This technique significantly reduces narcotic (morphine) requirements and enhances early recovery.

Regional Anaesthesia

Regional anaesthesia blocks sensation to a specific part of the body without affecting consciousness or breathing. As a senior Townsville orthopaedic surgeon, A/Prof Hazratwala strongly advocates opioid‑free and benzodiazepine‑free anaesthesia whenever suitable.

For patients undergoing day‑surgery arthroplasty, regional anaesthesia allows you to remain awake and comfortable. You may bring noise‑cancelling headphones to listen to music or watch a movie during your procedure.

Common regional techniques include:

Spinal Block

Anaesthetic injected into the fluid around the spinal cord, producing rapid numbness for several hours.

Epidural Block

A catheter delivers anaesthetic over a variable period. Similar location to a spinal block but placed in a different space.

Peripheral Nerve Block

Anaesthetic placed around major nerves (femoral or sciatic). Can be a single injection or a catheter delivering continuous anaesthesia for several days.

Advantages of regional anaesthesia include:

• Less blood loss
• Less nausea and drowsiness
• Improved pain control
• Reduced risk of serious complications such as heart attack or stroke

Side effects may include headaches, difficulty urinating, allergic reactions, or rarely nerve injury.

---

General Anaesthesia

General anaesthesia may be selected based on patient factors, surgeon preference, or anaesthetist recommendation. It affects the entire body, rendering you unconscious.

Administration

Medication is delivered via injection or inhalation. A breathing tube is placed to support ventilation.

Risks

Risks may be higher in patients with heart disease, lung conditions, or other serious medical issues. Common side effects include sore throat, hoarse voice, headache, nausea, and drowsiness.

A/Prof Hazratwala’s Recommendation

For most Townsville hip and knee surgery, A/Prof Hazratwala encourages regional anaesthesia due to its superior safety profile and reduced peri‑operative complications. His anaesthetists — Dr Segal, Dr Kaliaperumal, and Dr Lavender — are highly trained in advanced regional techniques and remain by your side throughout the procedure.

If at any point you feel anxious or uncomfortable, they can safely transition you to general anaesthesia.

A major scientific study has shown lower 30‑day mortality and better outcomes for hip and knee arthroplasty performed under regional anaesthesia.

Your Safety Comes First

Whether you are undergoing hip replacement in Townsville, knee replacement in Townsville, robotic hip and knee replacement, or ACL reconstruction in Townsville, your anaesthesia plan is designed to maximise comfort, minimise risk, and support the best possible recovery.
