Fascia iliaca compartment block (FICB) is a common regional analgesic strategy in hip fracture surgery but, recently it has been suggested that FICB may not provide enough analgesia. Pericapsular nerve group block (PENG) is a novel method for hip analgesia which its efficacy is not well established yet. The aim of this study was to the effect of the PENG block in the control of the hip fracture pain as well as to compare the effectiveness of the PENG compared with FICB. The hypothesis of this study was that the PENG block could be a good alternative to the FICB in hip fracture analgesia. This randomized controlled clinical trial was conducted in the Imam- Hossein Hospital, Tehran, Iran; between 2018 and 2019. Hip fracture patients were randomly divided into two groups; Group A (n=22) received FICB and Group B (n=30) received PENG block. There was no significant difference between VAS score before blocks procedure between two groups (p=0.37). After 15minutes of blocks and after 12hours of post-surgery, VAS score significantly reduced in the PENG block group compared with the FICB group (p=0.031; p=0.021, respectively). The first time of the analgesic consumption after surgery was significantly longer in the PENG block compared with the FCIB (p=0.007). Compared with the FICB group, the total dose of morphine consumption during 24hours significantly reduced in the PENG block (p=0.008). PENG block is a good method in hip fractures analgesia and provides better analgesia than FICB. However, further studies with larger sample sizes are required to validate the efficacy and superiority of the PENG blocks over conventional techniques. I. Copyright © 2021 Elsevier Masson SAS.
