Comparison of Pain Thresholds and Analgesic Effects of Parecoxib Sodium in Surgical Patients of Different Racial and Religious Backgrounds / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To explore the differences of the thresholds of pain and analgesic effects of parecoxib sodium among patients with different racial and religious backgrounds.</p><p><b>METHODS</b>A total of 48 male patients aged 18 to 38 years who had undergone elective laparoscopic appendectomy under general anesthesia in our centers were enrolled in our study and then divided into 6 groups(n=8 in each group)based on their racial backgrounds(three levelsMongoloid,Negroid,and Europoid)and religious backgrounds(two levelswithout religion background,with religion background).All subjects received the same anesthesia,surgical procedure,and postoperative analgesia with parecoxib sodium. The temperature pain threshold and electrical pain threshold were detected 1h before and after analgesia.</p><p><b>RESULTS</b>The threshold of pain was higher in Europoids than in Negroids and Mongoloids before and after treatment. The temperature pain threshold and electrical pain threshold were not significantly different between subjects with or without religious background(before analgesic therapyF=251.119,P=0.130,F=275.861,P=0.059;after analgesic therapyF=308.531,P=0.086,F=180.062,P=0.078). Also,there was no interaction between the racial and religious backgrous in terms of temperature pain threshold and electrical pain threshold(F=13.553,P=0.091,F=22.001,P= 0.089;after analgesic therapyF=4.624,P=0.089,F=15.935,P=0.094).</p><p><b>CONCLUSIONS</b>The threshold of pain differs among individuals with different racial background:it is highest in Europoids,followed by Negroids and Mongoloids. It shows no obvious difference in people with different religious backgrounds.</p>
