Background and Aims The aim of this study is to compare the postoperative analgesic efficacy of Suprainguinal Fascia Iliaca Block(FIB) and Lumbar Erector Spinae Plane Block(L-ESPB) in patients undergoing proximal femur fractures surgery.
Methods Patients with ASA(American Society of Anesthesiology)II-III were included and randomized into: FIB, L-ESPB, and control groups. Surgery was performed under spinal anesthesia in each group and preoperative block was performed in the related groups. Postoperative intravenous morphine via PCA(patient controlled analgesia) was administered and pain intensity was evaluated using NRS(Numeric Rating Scale).
Results A total of 63 patients were included. NRS scores at 12, 24 and 36th hours postoperatively were significantly lower in the FIB (1.18+-0.13, 0.82+-0.14, 1.0+-0.17) compared to the control group (2.05+-0.25, 2.14+-0.27, 1.81+-0.25) (p=0.006, p=<0.001, p=0.011, respectively). While the 12th and 36th hour NRS in the FIB were similar to those in the L-ESPB group, the 24th hour NRS in the FIB was significantly lower than in the L- ESPB group(1.60+-0.23) (p=0.01). NRS was similar between groups at 0, 2, 6 and 48th hours. Morphine consumption in the first 2hours and 2-6- hour period were significantly higher in the control group compared to other groups(p=0.018, p=0.021 respectively) and after 6th hour was similar among the three groups. The cumulative opioid use was higher in the control group at 6h,12h,24h,36h,48h hours where as it was similar between the FIB and L-ESPB groups in each time period.
Conclusions Combining FIB or L-ESPB with spinal anesthesia effectively reduced postoperative opioid consumption and provided better pain control. FIB demonstrated longer-lasting pain relief compared to L-ESPB.
