Comparing the Effect of Intramuscular Injection of Pethidine and Diclofenac Suppository in Relief of Pain Following Laminectomy Surgery

Pain, particularly after surgery, can create a variety of side effects including delay in woundhealing. different drugs such as pethidine and non-steroidal anti-inflammatory drugs are used forrelieving patient’s pain after surgery. the purpose of this research was to compare effect of pethidinevs. diclofenac suppository in relief of pain after laminectomy. a total of 100 patients who underwentlaminectomy entered this study. they were divided into pethidine and diclofenac groups. the patients’pain score was measured with visual analog scale (vas) method. the mean pain score 24 hours aftersurgery was 2.8 ± 2.0 in pethidine group and 4.46 ± 2.30 in diclofenac group. there was a significantstatistical difference between pain score after surgery in two groups (p < 0.05). nausea was the mostcommon side effect observed in pethidine group (20%) and epigastric pain was the most common onein diclofenac group (18%). there wasn’t any statistical significant difference between side effects inthese two groups. it seems that pethidine injection is more effective than diclofenac suppository inrelieving pain after laminectomy.
