Anaesthetic Techniques for neurosurgery
Jul 06, 2026
Neurosurgery requires an anaesthetic approach that is carefully tailored to both the patient and the procedure. Advances in neuroanaesthesia have expanded the range of techniques available, allowing anaesthetists to balance surgical access, neurological monitoring and a smooth postoperative recovery. For perianaesthesia nurses, understanding these approaches helps anticipate the patient's recovery profile and postoperative care needs.
One commonly used technique is total intravenous anaesthesia (TIVA), where anaesthesia is maintained using continuous intravenous medications rather than inhalational agents. TIVA is often selected when intraoperative neurophysiological monitoring is required, as it has less impact on the quality of monitoring signals. In other situations, volatile anaesthesia remains an appropriate choice and may offer advantages depending on the patient's condition, the type of surgery and the anaesthetist's preference. Many neurosurgical procedures also use a balanced anaesthetic technique, combining intravenous and inhalational agents to achieve the desired clinical effect.
Other aspects of the anaesthetic plan may include advanced haemodynamic monitoring, carefully planned airway management, goal-directed fluid therapy and medications that support optimal surgical conditions while facilitating timely neurological assessment after surgery.
Key considerations for perianaesthesia practice include:
💉 Recognise that TIVA, volatile anaesthesia or balanced techniques may all be appropriate depending on the procedure.
🧠 Anticipate a focus on timely emergence to allow early postoperative neurological assessment.
📊 Expect the use of advanced monitoring and individualised anaesthetic plans for complex procedures.
💊 Be aware that analgesia is carefully balanced to maintain patient comfort while avoiding excessive sedation that may delay neurological assessment.
👀 Prioritise frequent neurological observations and promptly escalate any unexpected changes during recovery.
Understanding the rationale behind different anaesthetic techniques allows perianaesthesia nurses to better anticipate recovery patterns, support postoperative assessment and contribute to safe, patient-centred care following neurosurgery.
