Neuroprotective effects of intravenous anesthetics: a new critical perspective Academic Article uri icon

abstract

  • Perioperative cerebral damage can result in various clinical sequela ranging from minor neurocognitive deficits to catastrophic neurological morbidity with permanent impairment and death. The goal of neuroprotective treatments is to reduce the clinical effects of cerebral damage through two major mechanisms: increased tolerance of neurological tissue to ischemia and changes in intra-cellular responses to energy supply deprivation. In this review, we present the clinical evidence of intravenous anesthetics on perioperative neuroprotection, and we also provide a critical perspective for future studies. The neuroprotective efficacy of the intravenous anesthetics thiopental, propofol and etomidate is unproven. Lidocaine may be neuroprotective in non-diabetic patients who have undergoing cardiac surgery with cardiopulmonary bypass (CBP) or with a 48-hour infusion, but …
