Clinical Trial Summary

Cerebral aneurysm surgery has significant mortality and morbidity rate. Inflammation plays a key role in the pathogenesis of intracranial aneurysms, their rupture, subarachnoid haemorrhage and neurologic complications. Brain injury activates immune cells and triggers cytokine release. Cytokine level in blood and cerebrospinal fluid is an indicator of inflammatory response. Cytokines contribute to secondary brain injury and can worsen the outcome of the treatment. Preventing secondary brain injury by modulating inflammatory response represents a therapeutic target. Lidocaine is local anesthetic that can be used in neurosurgery for regional anesthesia of the scalp and for topical anesthesia of the throat prior to direct laryngoscopy and endotracheal intubation. Except analgetic, lidocaine has systemic anti-inflammatory and neuroprotective effect. It acts through several mechanisms on various types of immune cells producing immunosuppressing effect. Lidocaine can act on activated microglia within central nervous system causing attenuation of immune response.

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.
