Objective: Total hip replacement (THR) is associated with severe postoperative pain. In this study, we aimed to compare fascia iliaca compartment block (FICB) with epidural block in the prevention of postoperative pain.

Material and Method: Our study included 40 patients; who underwent epidural analgesia and FICB. At the end of the operation, (Group FICB) who underwent ultrasound-guided FICB for postoperative analgesia and received 100 milligrams Bupivacaine hydrochloride +250 micrograms fentanylcitrate. Patients in Group EPI were given 100 milligrams bupivacaine hydrochloride and 250 micrograms fentanyl citrate an elastomeric pump containing 100 milligrams Bupivacaine hydrochloride +250 micrograms fentanylcitrate with 75 cc saline added, giving a total of 100 ml and infusing 2 cc/hour continuously for 48 hours was installed through an epidural catheter to obtain postoperative analgesia. Time to first analgesia request after the operation, total milligrams of meperidine received in the postoperative 24 hours, postoperative VAS scores at the 30th minute, 2nd hour, 6th hour, 12th hour, and 24th hour and patient satisfaction levels were evaluated.

Results: VAS scores at the postoperative 2nd, 6th, 12th, and 24th hours were statistically significantly higher in Group FICB compared to Group EPI (p <0.001). In addition, it was observed that the total analgesic consumption in the postoperative period was statistically significantly higher in Group FICB compared to Group EPI (p <0.001). The evaluation of patient satisfaction levels revealed that patients in Group EPI were very much satisfied (p <0.001).

Conclusion: In our study; we found out that postoperative pain levels and analgesic consumption were lower in epidural anaesthesia patients compared to the patients, who underwent fascia iliaca compartment block.
