Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In neurosurgical anesthesia, propofol based total intravenous anesthesia (TIVA) is frequently used due to brain relaxation and less effect on electrophysiologic monitoring. Response to propofol can vary between individuals and be associated with clinical factors including age and weight, and genetic polymorphism. Because the importance of rapid recovery in neurosurgery with long operation time is emphasized recently, the choice and dose adjustment of anesthetics should be determined according to clinical and genetic factors. Recently, researches about genetic variations have been performed with single nucleotide polymorphism (SNP). The aim of this study is to find SNPs associated with propofol recovery and response through genome-wide association study (GWAS) in Korean adult population undergoing propofol based TIVA for clipping of unruptured cerebral aneurysm.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Prospective Cohort

In adult patients undergoing propofol based TIVA for clipping of unruptured cerebral aneurysm, investigator will collect data regarding recovery after stopping propofol infusion (time for eye opening and extubation), propofol requirement during anesthesia maintenance, and propofol effect site concentration to achieve bispectral index 40 during anesthesia induction, without doing any interventions. Data collection will be established with just observing and recording values displayed in screens of monitoring devices, and reviewing patient charts.

No interventions assigned to this group

Retrospective Cohort

In previous study performed in adult patients undergoing propofol based TIVA for clipping of unruptured cerebral aneurysm (NCT02700126, 4-2015-1195), investigator enrolled patients and collected data regarding recovery after stopping propofol infusion (time for eye opening and extubation), propofol requirement during anesthesia maintenance, and propofol effect site concentration to achieve bispectral index 40 during anesthesia induction, without doing any interventions.
