BACKGROUNDPain during intra-operative and post-operative period of intracranial surgery causes severe fluctuations in haemodynamics, which can be detrimental for patients with compromised intracranial compliance. With scalp block, the sensory nerve fibres from the scalp and pericranial areas by using local anaesthetics and various adjuvants can reduce total anaesthetic requirement enabling early recovery and also reducing post-operative analgesic requirements.
