目的肺保护性通气(LPV)可将呼吸机引起的肺损伤(VILI)的风险降至最低。然而,LPV是否能够减轻呼吸机引起的膈肌功能障碍(VIDD)目前尚不清楚。本研究旨在探索LPV能否保护膈肌避免发生VIDD。方法成年雄性Wistar大鼠进行常规机械通气[潮气量(V_(T)):10 mL/kg,呼气末正压(PEEP):2 cmH_(2)O;CV组]或肺保护性通气(V_(T):5 mL/kg,PEEP:10 cmH_(2)O;LPV组)12 h。然后,收集膈肌和肺组织进行生化和组织学分析。结果笔者的研究结果表明,与常规机械通气组相比,肺保护通气减轻了大鼠的肺损伤,并降低了肺组织氧化应激水平。然而,与常规机械通气组相比,肺保护通气组的大鼠的膈肌蛋白水解水平增加,肌纤维横萎缩,膈肌肌力降低。此外,肺保护通气组在膈肌中的氧化应激水平高于常规机械通气组(P<0.05)。结论与常规机械通气相比,肺保护通气不能缓解大鼠膈肌发生VIDD。相比之下,肺保护通气可能通过诱导氧化应激使VIDD恶化。因此,找到一个合适的通气方式来同时保护肺和膈肌仍是具有挑战性和紧迫性的临床问题。
