Abstract: 

Background: Inguinal herniorrhaphy is one of the most prevalent surgical procedures which is performed under general, regional or local anesthesia. The postoperative pain is one of the reasons for discharge delaying in these patients. The aim of this study was to determine whether marcaine placed in the incisional area, subcutaneously decreases postoperative pain or opioid requirements.
Materials and Methods: In a triple blind randomized study, 67 patients undergoing unilateral inguinal herniorrhaphy were studied. Upon completion of the mesh repair, 1 mg/kg of either 0.25% marcaine (n=32) or normal saline (n=35) was injected into the incisional area, subcutaneously. Each patient's postoperative pethidine requirements using a patient controlled analgesia (PCA) pump during first 24 hours were recorded.
Results: A total of 67 patients (32 cases and 35 controls) with the mean age of 42.3
±17.2 years were studied. The mean duration of surgery in cases and controls were 48.8±23.8 mins and 44.5±26.6 mins, respectively. The groups did not differ in age, demographic characteristics, or duration of surgery.
Mean number of pethidine injections in cases and controls were 2 and 1.71, respectively. Surgery-first injection interval was 3.07
±2.24 hrs in cases and 3.1±3.7 hrs in controls which was not significantly different.
Conclusion: Incisional injection of marcaine did not decrease postoperative pain and opioid requirement. This issue has been confirmed by some previous studies but not in all. Incisional site (subcutaneous versus subfascial) and age groups may be the reason for this issue. Future studies are needed in order to reveal factors influencing patients' pain.
