LOPEZ GONZALEZ, J. et al. Analysis of the efficiency and safety of the ileofascial block for postoperatory pain after total knee arthroplasty. Rev. Soc. Esp. Dolor [online]. 2012, vol.19, n.5, pp.231-238. ISSN 1134-8046.

Objective: the importance of acute postoperative pain lies in its high frequency, where inadequate treatment and the impact it has on the evolution and the patient's recovery. Iliofascial block may be a suitable technique for postoperative analgesia after total knee arthroplasty. The aim of this study is to assess the efficacy and safety of the blockade iliofascial compared with epidural analgesia in postoperative effects in patients undergoing total knee arthroplasty under spinal anesthesia. We also evaluate if the iliofascial block is a safe analgesic technique, the complications, the adverse effects and the patient satisfaction. Material and methods: multicenter, prospective, randomized, observational, controlled, assessor blind, in 54 adult patients, ASA I-III, of both sexes, for total knee arthroplasty under spinal anesthesia. Patients included in the study were divided into two groups, BIF and BE. In the BIF group (n = 27), a iliofascial catheter was placed, while in the other group BE (n = 27), a lumbar epidural catheter (at L3-L4) was placed, both for continuous postoperative analghesia. Both groups received the same protocol with paracetamol and metamizol, and rescue with intravenous morphine bolus. Student t test was used to compare quantitative variables. p < 0.05 was considered significant. Results: There were no differences between groups in postoperative pain measured by VAS scale in the first hour after surgery and at 8, 12, 24 and 48 hours. The supplemental analgesia consumption was similar in both groups. Both techniques were easy and showed no complications related to any of them. No differences in side effects, motor block level, the degree of satisfaction with the analgesia received or sleep quality. Discussion: in our study as the epidural catheter as the catheter iliofascial provide good control of postoperative pain after total knee arthroplasty, with a degree of satisfaction of patients as good to very good. According to our results we think that the iliofascial block seems a safe and effective technique, so we could join to the analgesic protocol of knee arthroplasty.
