Summary

for the last 20 years, the increasing reports from non-human studies have raised suspicion that general anesthetics may cause neurotoxic changes in the developing brain that lead to adverse neurodevelopmental outcomes later in life.there are several case reports of reversible smell and taste dysfunction following exposure to general anesthesia suggesting a possible relationship between anesthetic agents and olfactory dysfunction. this study is to assess the possible neurotoxicity of sevoflurane,isoflurane,and propofol based anesthesia guided by olfactory changes

Detailed description

the primary inhibitory neurotransmitter GABA is found in neuronal synapses involving olfactory bulb. So, the involvement of common GABA pathway implies a possible interaction of general anesthetics with olfactory function. olfactory identification is an associative memory which is found to be facilitated by action of melatonin. involvement of GABA receptor in the transfer of light information from suprachiasmatic nuclei to pineal gland suggests possible interaction of melatonin and anesthetic agents. the aim of the study is to evaluate the possible neurotoxicity of sevoflurane,isoflurane,and propofol based anesthesia guided by olfactory changes
