Regional anesthesia techniques that provide analgesia to the entire lateral abdomen are limited. We present a modified external oblique intercostal block for complete lateral abdominal analgesia with a single injection.
We performed a modified version of the external oblique intercostal block unilaterally at the tenth rib along the mid-axillary line in three patients undergoing robot-assisted partial nephrectomy (two single injections, one catheter placement) and tested the technique on a cadaver with 20 ml of dye bilaterally. All patients reported good postoperative pain relief without complications and had consistent sensory coverage of the T8-T12 dermatomes from the anterior-to-posterior axillary line. Anatomical assessment confirmed consistent bilateral staining of the lateral cutaneous branches T8-T12.
Conclusions: The initial clinical success and anatomical findings of the modified approach to the external oblique intercostal block suggest that this technique may be an effective option for lateral abdominal analgesia.
能够为整个侧腹部提供镇痛的区域麻醉技术有限。我们介绍一种改良的腹外斜肌肋间阻滞术，通过单次注射实现完全的侧腹部镇痛。
我们对3例行机器人辅助部分肾切除术的患者，沿腋中线在第10肋水平单侧实施改良版腹外斜肌肋间阻滞术（2例单次注射，1例放置导管），并在一具尸体双侧注入20毫升染料以测试该技术。所有患者术后疼痛缓解良好，无并发症，且从腋前线到腋后线T8 - T12皮节的感觉覆盖一致。解剖学评估证实T8 - T12外侧皮支双侧染色一致。
改良腹外斜肌肋间阻滞术初步的临床成功及解剖学发现表明，该技术可能是侧腹部镇痛的有效选择。
