Methods: To operate 80 laparoscopic surgeries under the circumstance of general anaesthesia. Randomly divide them into 4 groups,with 20 cases in each group and the intravenous injection should be finished before the operation. Group Ⅰ: 2 ml normal saline; Group Ⅱ: 1.5 ml/kg tramadol; Group Ⅲ: 2mg/kg tramadol; Group Ⅳ : 2.5 mg/kg tramadol. Use VAS and Ramsay sedation marking system to assess the degree of pain-feeling and sedation in these circumstances: after pulling out oxygen hose, before leaving the operation room and1, 2, 4, 8, 12, 24 h after the operation. Meanwhile, record such side effects as nausea,vomiting, dizziness, hypersomnia, restless, nightmares, itchy and sweating. Results:The VAS score was significantly lower within postoperative 8 h in Group Ⅱ, Ⅲ andⅣ than that in Group I, while no significant difference was found among GroupⅡ, Ⅲand Ⅳ at each time point. The postoperative Ramsay sedation score was 0-2 in each group. Incidence of postoperative nausea, vomiting, and sweating were more in GroupⅡ, Ⅲ and IV than that in Group I. Group Ⅳ and Group I have statistical differences, in which P<0.05 or P<0.01. However, Group Ⅱ, Ⅲ and Group Ⅳ have no statistical differences. Conclusion: The study suggests that preoperative injection of 1.5-2 mg/kg tramadol provides satisfactory preoperative analgesia in patients undergoing gynaecological laparoscopy, reducing the use of analgesics and the incidence of side effects.展开更多
