It is well known that differences in drug reactions among individuals are widespread, and therefore the study of genetic polymorphisms of drug targets has become a research hotspot. Dexmedetomidine is clinically effective by acting on α2 adrenergic receptor and the impact of the adrenoceptor α2A gene (ADRA2A) polymorphisms on the anesthetic and analgesic effects of dexmedetomidine is related to the clinical application of dexmedetomidine. The present study aimed to analyze the effects of the rs1800035, rs201376588 and rs775887911 locus single-nucleotide polymorphisms of the ADRA2A on the anesthetic and analgesic effects of dexmedetomidine in Chinese Han women. A total of 434 Chinese women undergoing cesarean section were enrolled in this study. A 3-ml fasting venous blood sample was collected from all subjects for genomic DNA extraction and genotype detection. The pre-anesthetic and post-anesthetic pain threshold (PTh), pain tolerance threshold (PTTh), mean arterial pressure, heart rate, blood oxygen saturation, cortisol (Cor) content, blood glucose (Glu) content, opioid usage, patient-controlled analgesia pressing times, surgical satisfaction and postoperative adverse reactions were recorded. The visual analogue scale (VAS) and Ramsay sedation score were evaluated. PTh and PTTh in the wild-type women were higher than those in the women with mutations (P<0.05). The postoperative VAS scores of wild-type women were lower than those of mutants (P<0.05). The Ramsay sedation scores of wild-type patients at 12 h after the operation were significantly higher than in those with mutations (P<0.05). The levels of Cor and Glu in women with mutations were significantly higher than those of wild-type women at 12, 24 and 48 h after surgery (P<0.05). The satisfaction with surgery of wild-type patients was higher than that of patients with mutations (P<0.05). Gene mutations of rs1800035, rs201376588 and rs775887911 loci in the ADRA2A gene reduced the anesthetic and analgesic effect during and after cesarean section in Chinese Han women. Postoperative analgesia of mothers with mutations may require higher doses of analgesics.
