Local anaesthetics interrupt nerve conduction, while peripheral and neuraxial techniques target different anatomical sites. A regional block may provide surgical anaesthesia, analgesia or both. Explain expected effects and duration, and confirm that the planned technique is suitable for the operation and patient preferences.
Review consent, infection, anticoagulants, bleeding risk, neurological history and relevant cardiovascular disease. Contraindications depend on the technique and circumstances. Drug timing around neuraxial procedures requires current agent-specific guidance; a routine coagulation result does not answer every anticoagulant question.
Regional anaesthesia still requires appropriate monitoring, intravenous access and rescue capability. Sedation can add respiratory risk. Confirm block effectiveness before proceeding and plan for inadequate or failed block rather than assuming a technically completed injection guarantees surgical anaesthesia.
Local anaesthetic systemic toxicity can cause neurological symptoms, seizures or cardiovascular collapse, with variable presentation. Stop further administration, call for help and use the current specialist emergency checklist, including lipid therapy when indicated. Prevention includes dose calculation and trained technique, but risk is not eliminated completely.
Hypotension, unexpectedly extensive block or respiratory compromise needs prompt assessment and treatment. New or progressive neurological deficit after a neuraxial procedure, particularly with back pain or sphincter symptoms, needs urgent specialist evaluation for compressive complications. Do not label all persistent weakness as an ordinary block effect.
Read the relevant guideline sections alongside these original clinical teaching cases. Local pathways, available services and individual patient factors determine care.
