lidocaine as an induction agent for intracranial aneurysm surgery: a case series

conclusions although propofol remains a standard agent for such types of surgeries, lidocaine proved equally effective and coupled with its low cost, minimal side effects and omission of other hypnotic agents was a plausible induction agent and a maintenance drug in the selected cases. case presentation lidocaine was applied as the sole anaesthetic for induction and maintenance during aneurysm surgery in four patients undergoing intracranial aneurysm surgery. blood pressure alteration after induction and during surgery, bleeding, brain laxity, intracranial pressure and extubation time were acceptable. introduction induction of anaesthesia and its associated spikes in blood pressure can cause rupture of an aneurysm during intracranial surgery. lidocaine can reportedly provide hemodynamic stability when applied before endotracheal intubation. rapid injection of large doses of lidocaine can cause unconsciousness.
