Laryngoscopy and intubation elicits huge spectrum of stress response which is hazardous in high-risk patients. Many drugs and techniques have been used to attenuate the stress response. Lornoxicam 16 mg is a potent nonsteroidal anti-inflammatory drug agent with analgesic potency equivalent to morphine 10 mg, fentanyl 100 μg and tramadol 100 mg. Lornoxicam has been found to attenuate stress response in some studies. We compared the lornoxicam with fentanyl in attenuating stress response.
A double blind randomized controlled study was conducted on 60 adult patients of American Society of Anesthesiologist physical status 1 and 2. Group L ( = 30) receives injection lornoxicam 16 mg intravenous 30 min before induction, Group F ( = 30) receives injection fentanyl 2 μg/kg during induction. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) were recorded baseline (BL), before induction, every minute up to 5 min and at 10 min after intubation.
After intubation, there is a gradual decrease in SBP and DBP in both groups. The MAP was also comparable between the two groups except at 5 min and 10 min during which MAP recovered toward BL in Group L where as it remained low in Group F which was statistically significant ( < 0.05). Both the drugs have successfully attenuated the HR response.
Lornoxicam successfully attenuated the hemodynamic response to laryngoscopy and endotracheal intubation and is equally efficacious as fentanyl.
喉镜检查及气管插管会引发广泛的应激反应,这对高危患者具有危险性。许多药物和技术已被用于减轻这种应激反应。氯诺昔康16毫克是一种强效非甾体抗炎药,其镇痛效力等同于吗啡10毫克、芬太尼100微克和曲马多100毫克。在一些研究中发现氯诺昔康可减轻应激反应。我们比较了氯诺昔康和芬太尼在减轻应激反应方面的效果。
对60例美国麻醉医师协会身体状况1级和2级的成年患者进行了一项双盲随机对照研究。L组(n = 30)在诱导前30分钟静脉注射氯诺昔康16毫克,F组(n = 30)在诱导期间静脉注射芬太尼2微克/千克。记录基础状态(BL)、诱导前、插管前每分钟直至5分钟以及插管后10分钟时的收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP)和心率(HR)。
插管后,两组的SBP和DBP均逐渐下降。两组间的MAP在5分钟和10分钟时除外均具有可比性,在此期间L组的MAP恢复至基础水平,而F组的MAP仍保持较低水平,差异具有统计学意义(P < 0.05)。两种药物均成功减轻了HR反应。
氯诺昔康成功减轻了喉镜检查及气管插管引起的血流动力学反应,且与芬太尼效果相当。
