研究目的：
This study was conducted to explore whether the non-synonymous single-nucleotide polymorphisms in SCN9A gene can predict individual basal pain perception and postoperative pain intensity in the general population undergoing upper abdominal surgery. Methods: Patients receiving elective upper abdominal surgery under general anesthesia were recruited into this study. Genotyping of SCN9A was carried out by direct sequencing. The investigators measured their preoperative pressure pain threshold (PPT) and pressure pain tolerance (PTO). The visual analog scale (VAS) was used for pain evaluation at rest during patient-controlled analgesia (PCA) treatment 0 h, 12 h ,24 h and 48h after operation. And the PCA press frequency and drug consumption were recorded.
