Abstract:

Objective:To investigate the relationship between single nucleotide polymorphisms (SNPs) of cytochrome P450 (CYP450) 3A4 rs2242480 and interindividual differences of sufentanil consumption in accouchement sans douleur. Methods: A total of 131 parturient women were collected. According to the distribution of genotypes and allele frequencies of rs2242480, the doses of sufentanil were individually designed. CC homozygotes were given the standard analgesia dose, CT heterozygotes and TT homozygotes were given 87.6% of standard sufentanil dose. Results:Visual analogue score (VAS) between CC group and CT/TT group were 3.67±1.2 and 3.44±1.5, consistent with the expected analgesic standards. The difference was not statistically significant. Conclusion:The parturient women carrying CT heterozygotes and TT homozygotes of CYP3A4 rs2242480 required less sufentanil in accouchement sans douleur.
