Anaesthesia Care for Spinal Surgery: Your Guide to a Safe and Comfortable Experience

Last updated on 

Welcome! This leaflet provides essential information about anaesthesia care for spinal surgery procedures. Our team is dedicated to ensuring your safety and comfort throughout your journey. Please read this carefully and don't hesitate to ask questions.

Understanding Your Anaesthesia Plan

Spinal surgery procedures range from minor interventions (like discectomies) to complex reconstructive operations (like spinal fusions or scoliosis correction). Your anaesthesia plan is carefully tailored to your specific procedure, your overall health status, your preferences, and the surgeon’s needs. We will discuss your plan with you in detail before your surgery.

Types of Anaesthesia Offered

  • General Anaesthesia: You will be completely unconscious and unaware of the procedure. Breathing assistance will be provided through a breathing tube inserted into your airway. This allows the surgical team to focus on the procedure without your movement or discomfort.
  • Regional Anaesthesia: These techniques involve blocking nerve signals to the surgical area. They may be used alone or in combination with general anaesthesia.
    • Spinal Block: Medication is injected into the fluid surrounding the spinal cord, numbing the lower body.
    • Epidural Block: Medication is injected into the space around the spinal cord, providing pain relief during and after surgery.
    • Combined Techniques: Spinal or epidural blocks may be used alongside general anaesthesia to provide excellent pain control and potentially reduce the need for opioid pain medications.

Before Your Surgery: Preparation is Key

  • Pre-operative Assessment: A thorough review of your medical history, current medications (including over-the-counter drugs and supplements), allergies, and previous anaesthesia experiences. We will also discuss any concerns you have about anaesthesia.
  • Important Disclosures: Please inform us of:
    • Breathing problems (asthma, COPD)
    • Heart conditions (high blood pressure, heart failure)
    • Diabetes
    • Kidney or liver disease
    • Allergies to medications (especially anaesthetics)
    • Previous reactions to anaesthesia
    • Sleep apnoea
  • Fasting Guidelines: Strict adherence to fasting guidelines is crucial to prevent complications during anaesthesia.
    • No food or drink for 6 hours before surgery. Specific timing will be confirmed by your anaesthesiologist.
    • Clear liquids (water, clear juice, black coffee) may be allowed up to 2 hours before surgery, but this will be confirmed by your anaesthesiologist.
  • Medication Adjustments: Certain medications may need to be stopped or adjusted before surgery. This will be discussed with you and your surgeon.
  • Hydration: Maintain adequate hydration in the days leading up to surgery.
  • Smoking Cessation: Smoking can negatively impact anaesthesia and healing. We strongly recommend stopping smoking 4–6 weeks before surgery.

During Your Surgery

  • Positioning: You will typically lie face down on a specialised surgical table with padding to protect pressure points and allow for proper breathing. The position can be uncomfortable, and we will do our best to make you as comfortable as possible.
  • Continuous Monitoring: We will continuously monitor your vital signs, including:
    • Heart rate and rhythm (ECG)
    • Blood pressure
    • Oxygen levels (pulse oximetry)
    • Breathing patterns
    • Body temperature
    • Neurological function (nerve stimulation may be used to monitor nerve block placement)
  • Airway Management: If general anaesthesia is used, a breathing tube will be inserted into your airway to assist with breathing.

Pain Management Approach

  • Multimodal Pain Relief: A multimodal approach will be used, combining different pain relief methods to minimise opioid use. This may include:
    • Local Anaesthetics: Injected directly into the surgical site to provide localised pain relief.
    • Anti-inflammatory Medications: To reduce inflammation and pain.
    • Nerve Blocks: To block pain signals from the surgical area.
    • Opioid Medications: Used judiciously for breakthrough pain.
  • Patient-Controlled Analgesia (PCA): You may receive a PCA pump, allowing you to control pain medication delivery within safe limits, as prescribed by your anaesthesiologist.

Safety & Recovery Considerations

  • Recovery Room Monitoring: You will wake up in the recovery room under close monitoring.
  • Immediate Pain Management: Pain assessment and management will begin immediately.
  • Gradual Return: Expect a gradual return of sensation and movement.
  • Common Discomforts:
    • Sore Throat: From the breathing tube.
    • Nausea: Is possible but treatable.
    • Muscle Aches: From the surgical position.
  • Movement Restrictions: Follow movement restrictions as directed by the surgical team.

Frequently Asked Questions (FAQ)

  • Q: What are the risks of anaesthesia? A: Risks are minimised through careful assessment and monitoring. Common side effects are temporary. Serious complications are rare. We will discuss these risks with you in detail.
  • Q: How long will I feel the effects of anaesthesia? A: Effects vary depending on the type of anaesthesia and individual factors.
  • Q: Can I eat or drink after surgery? A: You will receive instructions on when you can resume eating and drinking.
  • Q: When can I drive again? A: You should not drive until the effects of anaesthesia have completely worn off, typically several days.

Glossary of Terms

  • ECG: Electrocardiogram, a test that measures the electrical activity of the heart.
  • IV: Intravenous, administered directly into a vein.
  • PCA: Patient-Controlled Analgesia.
  • Pulse Oximetry: A non-invasive method of monitoring oxygen saturation.
