Intravenous dexamethasone and diclofenac were evaluated in a double blind randomised trial, relative to an opioid (pentazocine) and placebo (saline), in 160 patients undergoing extraction of impacted lower third molar teeth. Test drugs were administered intravenously before surgery to provide postoperative analgesia. Following the operation, pain was assessed using a 10 cm visual analogue scale. Patients who received diclofenac reported significantly less pain than others 30 minutes after surgery (p less than 0.05). Pain scores on the day following surgery were also significantly lower in the diclofenac group compared to the opioid and placebo groups (p less than 0.05) but not less than those who received dexamethasone--possibly indicating a long term advantage of the anti-inflammatory drugs. Vomiting was a problem in the opioid group.
在一项双盲随机试验中,对160例接受拔除下颌阻生第三磨牙手术的患者,评估了静脉注射地塞米松和双氯芬酸相对于一种阿片类药物(喷他佐辛)和安慰剂(生理盐水)的效果。术前静脉注射试验药物以提供术后镇痛。术后,使用10厘米视觉模拟量表评估疼痛程度。接受双氯芬酸治疗的患者在术后30分钟报告的疼痛明显少于其他患者(p<0.05)。与阿片类药物组和安慰剂组相比,双氯芬酸组术后第一天的疼痛评分也显著更低(p<0.05),但不比接受地塞米松的患者低——这可能表明抗炎药物具有长期优势。呕吐是阿片类药物组的一个问题。
