A118G Single Nucleotide Polymorphism of Human fx-Opioid Receptor Gene Influences Pain Perception and Patient-controlled Intravenous Morphine Consumption after Intrathecal Morphine for Postcesarean Ana

摘要

Background: Previous studies have shown that genetic variability at position 118 of the human,-opioid receptor gene altered patients' response to intravenous morphine. The purpose of this study was to investigate whether this polymorphism contributes to the variability in response to morphine for postcesarean analgesia
