研究目的: |
主要研究目的:旨在评估与标准策略相比,TEE引导的个体化肺复张策略在以下两个关键临床结局上的优效性: 验证该策略能否显著降低心脏手术患者术后7天内中重度肺部并发症的发生率。 探究该策略能否显著降低患者术后谵妄的发生率、严重程度及持续时间。 次要研究目的:旨在全面评估该策略的多维度效应及潜在机制: 证实该策略能即时并持续改善患者术后的氧合功能与呼吸系统顺应性。 评估该策略能否缩短机械通气时间、ICU停留时间及总住院时间。 探索该策略对患者术后1个月及3个月神经认知功能的保护作用。 通过检测围术期炎症标志物的动态变化,分析其与临床结局的关联,从生物学层面阐释 “肺-脑轴” 机制。 |

Objectives of Study: |
Primary research objectives: To evaluate the superiority of a TEE-guided individualized lung recruitment strategy compared to standard strategies in the following two key clinical outcomes: 1) To verify whether this strategy can significantly reduce the incidence of moderate to severe pulmonary complications within 7 days after cardiac surgery. 2) To explore whether this strategy can significantly reduce the incidence, severity, and duration of postoperative delirium in patients. Secondary research objectives: To comprehensively assess the multidimensional effects and potential mechanisms of this strategy: 1) To confirm whether this strategy can immediately and sustainably improve patients' postoperative oxygenation and respiratory system compliance. 2) To evaluate whether this strategy can shorten the duration of mechanical ventilation, ICU stay, and total hospitalization time. 3) To explore the protective effects of this strategy on patients' neurocognitive function at 1 month and 3 months postoperatively. 4) To analyze the correlation between perioperative inflammatory marker dynamics and clinical outcomes, thereby elucidating the "lung-brain axis" mechanism from a biological perspective. |
