A significant subgroup of patients suffer from moderate or severe pain after total hip arthroplasty (THA). Regional analgesia has the potential to reduce post-operative pain and thereby spare patients from opioids, but regional analgesia of the hip is complicated as the area is innervated by multiple nerves. However, the nociceptors of the hip joint are primarily innervated by the obturator and femoral nerves. The effect of an obturator nerve block (ONB) on pain following THA has never been investigated. A femoral nerve block is known to reduce pain after THA, but is unfortunately accompanied by an increased risk of fall. We have developed a novel nerve block-the iliopsoas plane block (IPB)-that has the potential to anaesthetize the hip articular sensory branches of the femoral nerve without causing motor blockade.
在全髋关节置换术后，相当一部分患者会遭受中重度疼痛。区域镇痛有可能减轻术后疼痛，从而避免患者使用阿片类药物，但髋关节的区域镇痛较为复杂，因为该区域由多根神经支配。然而，髋关节的伤害感受器主要由闭孔神经和股神经支配。闭孔神经阻滞（ONB）对全髋关节置换术后疼痛的影响从未被研究过。股神经阻滞已被证实可减轻全髋关节置换术后的疼痛，但不幸的是，它会增加跌倒的风险。我们开发了一种新的神经阻滞技术——髂腰肌平面阻滞（IPB），它有可能麻醉股神经的髋关节关节感觉支，而不会引起运动阻滞。
