Spinal Anaesthesia


What Is Spinal Anaesthesia?

Spinal anaesthesia is a technique used to temporarily prevent nerves in the lower half of the body from carrying pain signals. It is most commonly used to provide anaesthesia during a surgical or medical procedure. The anaesthetic effect usually lasts for several hours, depending on the amount of anaesthetic used. Spinal anaesthesia is administered by an anaesthesiologist or a qualified anaesthetist. It involves injecting an anaesthetic drug into the spinal column near the lower back. The anaesthetic then acts locally to numb the nerves in the lower half of the body.

Advantages of Spinal Anaesthesia

  • Provides fast onset of anaesthesia.
  • Allows the patient to remain awake during the procedure.
  • Does not require general anaesthesia, which carries a greater risk of complications.
  • Provides a more efficient and controllable anaesthetic effect.
  • Reduces the amount of time spent under anaesthesia.

Disadvantages of Spinal Anaesthesia

  • Potential for increased risk of complications compared to general anaesthesia.
  • Increased risk of infection due to injection into an unsterile area.
  • Possibility of nerve damage and paralysis.
  • Increased risk of developing a post-anaesthetic headache.
  • Potential for allergic reaction if the patient is sensitive to the anaesthetic drug.

In conclusion, spinal anaesthesia can be a useful and effective anaesthetic technique in some situations. It has some advantages over general anaesthesia, but there are also associated risks that should be taken into account. It is important to discuss any concerns with an anaesthesiologist prior to having this procedure.
