To investigate the effects of patient-controlled intravenous analgesia (PCIA) with lornoxicam and fentanyl on arrhythmia and the expression of platelet membrane glycoproteins in patients with coronary artery disease (...To investigate the effects of patient-controlled intravenous analgesia (PCIA) with lornoxicam and fentanyl on arrhythmia and the expression of platelet membrane glycoproteins in patients with coronary artery disease (CAD) after abdominal surgery.Methods Eighty ASA Ⅱ or Ⅲ patients with CAD aged 51～66 yrs weighing 59～68 kg presenting for abdominal surgery participated in this study.CAD was diagnosed by clinical symptoms and ischemic changes on ECG.The patients were premedicated with intramuscular henobarbital 0.1 g and scopolamine 0.3 mg.Anesthesia was induced with fentanyl,droperidol,propofol and vecuronium and maintained with propofol,fentanyl and vecuronium.The patients received PCIA after operation.The PCIA solution contained fentanyl 0.9 mg and droperidol 5 mg in 100 ml of normal saline (N.S.) in group A (n=40) or lornoxicam 56 mg,fentanyl 0.2 mg and droperidol 5 mg in 100 ml N.S. in group B (n=40).In group A the loading dose was fentanyl 0.05 mg and group B lornoxicam 4 mg.PCIA included a background infusion at 2 ml·h -1 and a bolus of 0.5 ml with a 15 min lock-out.VAS(0=no pain,10= worst pain) was used to measure pain intensity.In addition to BP,HR and SpO2 monitoring ECG was continuously monitored with a Holter monitor after operation.Blood samples were taken from peripheral vein before and 6 h after operation and on the 1st,2nd,7th and 8th postoperative days for determination of the expression of CD 62p ,CD 63 and CD 41 /CD 61 on the platelet membrane,platelet count,prothrombin time (PT) thrombin time (TT) and partial thromboplastin time (PTT).Results The two groups were comparable with respect to sex,age,body weight,severity of CAD,duration of operation and intraoperative blood loss.The patients received no blood transfusion during operation.There was no significant difference in VAS score,platelet count,PT,TT and PTT between the two groups.The incidence of atrial and ventricular premature beat on ECG and the expression of CD 41 /CD 61 ,CD 62p and CD 63 on the platelet membrane were significantly lower in group B than in group A on the 7th and 8th postoperative days(P<0.05 or 0.01).Conclusion Postoperative PCIA with lornoxicam and fentanyl can more effectively reduce the incidence of postoperative arrhythmia in patients with CAD.Suppression of activation of platelets by lornoxicam may contribute to the mechanism.10 refs,3 tabs.展开更多

Methods Thirty-nine patients scheduled for abdominal surgeries were randomly assigned to different PCA treatment groups using either lornoxicam or fentanyl postoperatively. Pain intensity difference (PID) and sum of pain intensity difference (SPID) were used to assess the analgesic efficacy of both drugs during a 24-hour period. Results The analgesic efficacy of lornoxicam is 1/66 of fentanyl, which was shown by SPID value of 3.250 and 3.058, respectively (P > 0.05). Lornoxicam caused fewer adverse events than fentanyl (33% vs. 68%, P < 0.05). Conclusion In clinic, we can use lornoxicam to treat postoperative pain effectively and with less adverse reactions com-pared with fentanyl.展开更多
Lornoxicam (6-chloro-4-hydroxy-2-methyl-N-2-pyridyl-2H-thieno-[2,3-e]-1,2-thiazine-3-carboxamide-1,1-dioxide) is persist as a non-steroidal anti-inflammatory drug of the oxicam class with analgesic, anti-inflammatory ...Lornoxicam (6-chloro-4-hydroxy-2-methyl-N-2-pyridyl-2H-thieno-[2,3-e]-1,2-thiazine-3-carboxamide-1,1-dioxide) is persist as a non-steroidal anti-inflammatory drug of the oxicam class with analgesic, anti-inflammatory and antipyretic properties. A fast, accurate and sensitive chromatographic method for estimation of Lornoxicam was developed as no official method available for detection. The chromatographic separation employs isocratic elution by utilizing an inertsil ODS-C 18 , 250 mm×4.6 mm, 5 μm columns. Mobile phase consisting of solvent (40 mL acetonitrile and 60 mL 0.1 M phosphate buffer (pH 6.8 was adjusted with triethylamine)) endowed at a flow rate of 1.0 mL/min. The analyte was detected and quantified at 290 nm using UV detector. The method was validated according to ICH guidelines, illustrating to be accurate (recovery 99.08%-101.13%) and precise (intraday (0.27-1.32) and interday (0.59-1.59))within the corresponding linear range (10-60 μg/mL) with r 2 0.9992.展开更多
