Abstract
Abstract
Context:
Peripheral nerve blocks are widely accepted as the gold standard for providing perioperative and postoperative analgesia in lower limb surgeries.
Aims:
This study aimed to determine which block is better in terms of onset of action among ultrasound-guided femoral nerve block (USG FNB) and ultrasound-guided fascia iliaca compartment block (USG FICB) for positioning for spinal anesthesia in patients operated for proximal femur fracture and find the total duration of analgesia, total consumption of rescue analgesics, and complications.
Settings and Design:
This was a prospective, randomized, comparative, interventional, single-blinded study.
Subjects and Methods:
Patients in Group A (n = 43) were administered USG FNB with 15 mL of 0.25% bupivacaine and patients in Group B (n = 43) were administered USG FICB with 30 mL of 0.25% bupivacaine. The primary objective was to find out which nerve block was better in reducing pain associated with a sitting position for spinal anesthesia, and the secondary objective was to find the difference in the mean time of first rescue analgesia.
Statistical Analysis:
Data analysis was done using the Student’s t-test and Chi-square tests.
Results:
Before block administration, patients in Group A had a Visual Analog Scale (VAS) score of 7.65 ± 0.75, and patients in Group B had a VAS score of 7.79 ± 0.74 (P = 0.389). The primary objective was to achieve VAS < 3. It was 3 min in Group A and 5 min in Group B (P = 001). The secondary objectives were the duration of postoperative analgesia in Group A was 330.58 ± 28.16 min and in Group B was 482.33 ± 19.89 min (P < 0.001). The mean value of tramadol consumption in 24 h in both the study groups was comparable (P = 1.000). The anesthesiologist satisfaction score, patient satisfaction score, and proportion of side effects in both study groups were comparable.
Conclusion:
USG FICB is more efficacious. Although the onset of action delays by 2 min, it provides longer postoperative analgesia compared to USG FNB.
