背景与目的改良经软骨膜入路胸腹神经阻滞（M-TAPA）的镇痛范围和作用机制目前尚无统一的认识。这尸体研究的目的是确定以下模拟M-TAPA.MethodsSimulated M-TAPA注射液（n=8）的传播管理软防腐Thiel尸体与25毫升的盐水可溶性染料的两侧。进行解剖解剖以记录染色（深深地，淡淡地，结果染色的节段神经的正中皮区（IQR）为T10（T8-T11），正中皮区（IQR）为T10（T8-T11），正中皮区（IQR）为T10（T8-T11）。染色节段神经3条（4-2条）。T9、T10和T11节段神经的染色率分别为75%、100%和62.5%。相反，T8节段神经仅在25%的模拟M-TAPA中染色。没有注射液传播的染料在胸腔的肋间空间中观察到在8个模拟注射M-TAPA.ConclusionOur研究结果表明，M-TAPA最有可能涉及T9，T10和T11节段神经和局部麻醉剂可能不会蔓延到肋间空间在胸腔中的M-TAPA。需要进一步的研究来证实M-TAPA在大样本人类参与者中的确切作用机制和疗效。
Background and objectivesThere is still no consensus on the analgesic range and mechanisms of action of modified thoracoabdominal nerve block through perichondrial approach (M-TAPA). This cadaveric study aimed to determine the spread of an injectate following simulated M-TAPA.MethodsSimulated M-TAPA injections (n=8) were administered on both sides of soft embalmed Thiel cadavers with 25 mL of a saline-soluble dye. Anatomic dissection was performed to document staining (deeply, faintly, or not stained) of the anterior cutaneous branches of the thoracoabdominal nerves and determine the extent of the injectate spread of the dye to the intercostal space in the thoracic cage following a simulated M-TAPA.ResultsThe median (IQR) dermatome of the stained segmental nerve was T10 (T8–T11) and the median (IQR) number of stained segmental nerves was 3 (4–2). The T9, T10 and T11 segmental nerves were stained in 75%, 100% and 62.5% of simulated M-TAPA, respectively. Conversely, the T8 segmental nerve was stained in only 25% of simulated M-TAPA. No injectate spread of dye to the intercostal space in the thoracic cage was observed in eight simulated injections of M-TAPA.ConclusionOur findings suggest that M-TAPA most likely involves the T9, T10 and T11 segmental nerves and that the local anesthetic may not spread to the intercostal space in the thoracic cage in M-TAPA. Further studies are required to confirm the precise mechanism of action and efficacy of M-TAPA in a large sample of human participants.
