Efficacy of intravenous dexketoprofen trometamol compared to intravenous paracetamol for postoperative pain management after day-case operative hysteroscopy: Randomized, double-blind, placebo-controlled study

Abstract

Objective: Adequate pain management following day-case surgery allows early ambulation of patients. In this study, we aimed to compare postoperative analgesic efficacy of intravenous (iv) dexketoprofen vs. iv paracetamol following day-case operative hysteroscopy. Methods: One hundred and fourteen American Society of Anesthesiologists (ASA) I-II patients scheduled for day-case operative hysteroscopy were recruited and randomized to three groups in the study. Group D received 50 mg iv dexketoprofen trometamol, Group P 1000 mg iv paracetamol and Group C normal saline solution. Visual Analogue Scale (VAS) pain intensity, pain relief, sedation, nausea-vomiting, other side effects, and additional opioid analgesic requirement were noted at postoperative 15 minutes (min), 30 min, 1 hour (h), 2 h, and 3 h. Patients with VAS ≥40 mm received meperidine 0.25 mg/kg as rescue analgesic medication. Results: VAS scores at 15 min, 30 min, 1 h, and 2 h were significantly lower in Group D compared to Group C. VAS scores at 15 min and 30 min were significantly lower in Group D compared to Group P. The percentages of patients who required opioid treatment were 34%, 60%, and 63% in Groups D, P and C, respectively (p<0.05). Total delivered opioid dose was 0.10±0.16 mg/kg, 027±0.33 mg/kg and 0.28±0.25 mg/kg in Groups D, P and C, respectively (p<0.05). Pain relief score was significantly better in Group D at postoperative 15 min when compared with Group C (p<0.05). Conclusion: Our study demonstrated that iv dexketoprofen has superior efficacy for postoperative pain management following daycase operative hysteroscopy when compared with paracetamol and placebo.
