Abstract
Background &Objectives: Hip arthroscopy is a minimally invasive technique and it has become widely used for many hip joint diseases. However, severe postoperative pain usually accompanies these surgeries with increased demands for multimodal pain control strategies. Regional blocks such as femoral nerve block (FNB) and fascia iliaca compartment block (FICB) enable better postoperative analgesia with less parenteral opioid use. This study aimed to assess and compare the efficacy of ultrasound (US)-guided (FNB) versus (US) guided (FICB) regarding intraoperative and postoperative analgesia and postoperative motor power.
Methodology: 60 patients who were planned for hip arthroscopy, aged 21 - 65 years, of either sex and ASA I - II were enrolled in the study. They were randomly divided into 2 groups: group (FICB) (n= 30) in which FICB with 40 mL levobupivacaine 0.25% was done after induction of general anesthesia (GA) and group (FNB) (n = 30) in which FNB with 20 mL levobupivacaine 0.25% was done after induction of GA. Time to the first analgesic use was the primary outcome, whereas total morphine and pethedine consumption in the first 24 h postoperatively, VAS score, and the Assessment of postoperative early ambulation were the secondary outcomes.
Results: Patients in the FICB group experienced a significantly short time till ambulation (17.2±2.1 hours) in comparison to group FNB(19.8±2.1) with (P < 0.001). There were no significant differences between the 2 groups regarding time to first analgesic requirement, total morphine consumption, total pethedine consumption, and VAS scores. No cases of drug allergy were reported in both group.
Conclusion: Both FICB and FNB were effective in reducing postoperative pain, however, FICB was superior regarding motor power and early ambulation.
Key words: Hip arthroscopy, femoral nerve block, Fascia iliaca compartment block.
