Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Primary aim of this prospective randomized trial is to determine influence of lidocaine administration on inflammatory cytokine levels in serum and cerebrospinal fluid during and following cerebral aneurysm surgery. Secondary aim is to determine possible correlation between levels of cytokines and incidence of neurologic and infectious postoperative complications. For that purpose, postoperative neurological clinical status will be recorded. Signs of vasospasm and pathological postoperative brain CT scan findings will be recorded. Incidence of meningitis, pneumonia and sepsis in postoperative period will also be analyzed.
Hypothesis of this trial is that lidocaine administration during cerebral aneurysm surgery would significantly change levels of pro-inflammatory cytokines in cerebrospinal fluid and serum. Lower concentrations of pro-inflammatory cytokines can possibly contribute to better outcome and significantly lower incidence of postoperative complications. Enzyme-immunochemical analysis will be used to measure levels of interleukin-1β, interleukin-6 and tumor necrosis factor-α in cerebrospinal fluid and serum. Investigation group will have, during cerebrovascular surgery under general anesthesia, regional anesthesia of the scalp and topical anesthesia of the throat prior to laryngoscopy, all done with lidocaine. Control group will have general anesthesia without lidocaine administration.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Lidocaine group
Participants in lidocaine group, following induction to general anesthesia, will have lidocaine 2% 4 mg/kg administered as regional anesthesia of the scalp prior to Mayfield frame placement and lidocaine 1% 40 mg topically to the throat prior to direct laryngoscopy and endotracheal intubation. Maximum dosage of lidocaine won't exceed 400 mg.
Lidocaine
Administration of lidocaine 2% 4 mg/kg administered as regional anesthesia of the scalp prior to Mayfield frame placement and lidocaine 1% 40 mg topically to the throat prior to direct laryngoscopy and endotracheal intubation.
Control group
Participants in control group will have general anesthesia without lidocaine administration.
