Background and Aims Fascia iliac block is one of the well-known methods for local analgesia in hip surgeries. However, the implementation approach of this method has significant effects on its effectiveness . We investigated the effectiveness of the supra inguinal (S-FICB)in comparison with infra inguinal fascia Iliaca (I-FICB).
Methods The current study was a randomized, double-blind clinical trial that was conducted on 56 patients. The participants in the study were randomly divided into two groups. Pain index based on NRS score after surgery was the main outcome, which was compared at 1, 4, 8, 16, and 24 hours. The pain score during rest and movement was compared. The amount of morphine consumed, the first time of morphine request, and the occurrence of complications were secondary outcomes.
Results The average pain score at rest and movement at 1, 4, 8, and 16 hours after surgery in the S-FICB group was lower than I-FICB. The observed difference was statistically significant (P-value<0.05). The mean consumption of morphine was lower in the supra-inguinal group, but the difference was not significant (P-value>0.05). The average time of requesting the first dose of morphine was also higher in the S-FICB than in the I-FICB, and the difference was not statistically significant (P-value>0.05). No significant difference was observed in the occurrence of complications. The level of satisfaction was significantly higher in the supra-inguinal group (P-value<0.05)
Conclusions Both approaches were well tolerated by patients and had few side effects. However, the S-FICB was more effective in postoperative pain reduction and patient satisfaction was also higher.
