Ketorolac tromethamine (Toradol) is a parenteral, nonsteroidal antiinflammatory drug that is being extensively used to provide postoperative analgesia. This study evaluated whether intraoperative ketorolac would act synergistically with fentanyl to decrease postoperative analgesic requirements in outpatients undergoing gynecologic procedures. The patients studied were adult ASA physical status I or II females scheduled for diagnostic laparoscopy (DL) (n = 80) or laparoscopic tubal ligation (TL) (n = 46). Each patient received fentanyl 2 micrograms/kg intravenously (i.v.) before induction, followed by a standardized propofol anesthetic and 2 mL of saline or ketorolac 60 mg i.v. in a randomized double-blind fashion 30 min before the anticipated end of the operative procedure. Patients were assessed for postoperative pain via a 10-cm visual analog scale (VAS) (0 = no pain; 10 = severe pain) before analgesic treatment in the postanesthesia care unit (PACU). Severe postoperative pain (VAS or 5 or more) was treated with incremental doses of fentanyl, 25-50 micrograms i.v. by a blinded PACU nurse. Ibuprofen or acetaminophen with codeine was administered for pain control once the patient tolerated oral medications. This study showed that intraoperative ketorolac (60 mg i.v.) with fentanyl (2 micrograms/kg i.v.) administered at the induction of anesthesia resulted in significant opioid sparing and a diminution in pain in the DL sample but not in the TL sample. The analgesic regimen was also associated with a lower incidence of nausea and vomiting and resulted in earlier discharge, which was not seen after TL. These results demonstrate that pain after TL is far greater than that after DL, which suggests that these procedures should be considered separately when designing analgesic regimens.
酮咯酸氨丁三醇(托拉朵)是一种胃肠外非甾体类抗炎药,目前被广泛用于术后镇痛。本研究评估了术中使用酮咯酸是否会与芬太尼协同作用,以降低接受妇科手术的门诊患者术后的镇痛需求。研究对象为计划接受诊断性腹腔镜检查(DL)(n = 80)或腹腔镜输卵管结扎术(TL)(n = 46)的成年ASA身体状况为I或II级的女性患者。每位患者在诱导前静脉注射(i.v.)2微克/千克芬太尼,随后接受标准化丙泊酚麻醉,并在预计手术结束前30分钟以随机双盲方式静脉注射2毫升生理盐水或60毫克酮咯酸。在麻醉后护理单元(PACU)进行镇痛治疗前,通过10厘米视觉模拟量表(VAS)(0 = 无疼痛;10 = 剧痛)对患者的术后疼痛进行评估。术后严重疼痛(VAS≥5)由PACU的一名不知情护士静脉注射递增剂量的芬太尼(25 - 50微克)进行治疗。一旦患者能够耐受口服药物,即给予布洛芬或对乙酰氨基酚加可待因以控制疼痛。本研究表明,麻醉诱导时静脉注射酮咯酸(60毫克)与芬太尼(2微克/千克静脉注射)联合使用,在DL样本中可显著减少阿片类药物用量并减轻疼痛,但在TL样本中未出现此效果。该镇痛方案还与较低的恶心和呕吐发生率相关,并导致更早出院,TL术后未观察到这一情况。这些结果表明,TL术后的疼痛远大于DL术后的疼痛,这表明在设计镇痛方案时应分别考虑这些手术。
