Abstract:Objective: This study examined preemptive paracetamol, Nonsteroidal Anti-Inflammatory (NSAIDs) and their combinations in terms of their effects on the quality of the analgesia developed after post-abdomen surgery via Patient Controlled Analgesia (PCA), total fentanyl dose and related side effects.Material and method: 120 patients (SA I-II; age range: 18-70 years old) planned to undergo elective abdominal surgery under general aesthesia were randomly classified into four groups. Thirty (30) minutes before the preemptive surgery, the cases in Fentanyl Group (GF, n=30) were administered 100 ml iv 0.9% NaCl; the cases in Paracetamol Group (GP, n=30) 1 g iv paracetamol; the cases in NSAID Group (GN, n=30) 8 mg iv lornoksicam; and the cases in Paracetamol and NSAID Group (GPN, n=30) 1 g iv paracetamol and 8 mg iv lornoksicam. Anaesthesia induction was performed in all cases via 2 mg/kg propophol and 0.6 mg/kg rocuronium. Maintenance of anaesthesia was ensured via 60% Nitrous oxide ? 40% O2, 1?1.5% sevoflurane. In the postoperative period; iv fentanyl was administered to the control group cases (Group F) via the postoperative patient-controlled analgesia (PCA) device. In the remaining cases, in addition to the iv fentanyl, i.v paracetamol 1 g was infused to Group P cases at the postoperative 6th, 12th and 18th hours; i.v paracetamol 1g was infused to Group PN cases at the postoperative 6th, 12th and 18th hours; and no additional drug was infused to Group N cases at the postoperative hours. VAS score, blood pressure and heart rate, sedation score, nausea-vomiting score, patient satisfaction, side effects and total fentanyl dose were recorded at the postoperative 2nd, 4th, 8th, 12th and 24th hours. One Way ANOVA test and Chi-Square test were used for statistical analysis.Results: There was no difference between the groups in terms of demographic data (p>0.05). Total fentanyl consumption in the postoperative 24-hour period was recorded to be statistically significantly higher in Group F than in Group P, Group N and Group PN (p=0.001). Fentanyl consumption in Group N at the 2nd, 8th, 12th and 24th hours was found to be statistically significantly lower than Group F (p=0.012, p=0.009, p=0.004, p= 0.001). Fentanyl consumption of Group PN was found to be statistically significant lower than that of Group F at all postoperative measurement hours (p=0.004, p=0.001, p=0.001, p=0.001, p=0.001). No statistically significant difference was recorded between Group F and Group P at postoperative 2nd, 4th, 8th, and 12th hours (p>0.013). Respiratory depression, bradycardia and hypotension were not reported in any study cases.Conclusion: It was observed that preemptive 8mg lornoksicam reduced fentanyl consumption in patient-controlled analgesia, preemptive paracetamol had no such effect and lornoksicam-parecetamol combination did not prevail over use of lornoksicam alone.Keywords: i.v.
