术后肺部并发症(postoperative pulmonary complications, PPCs)是手术后常见的严重问题,尤其在胸腹部手术以及需要气管插管和机械通气的患者中更为突出,通常发生在术后7 d内。有效的围手术期管理,包括优化肺保护性通气策略、实时监测肺部通气状态并进行及时干预,可显著降低PPCs的发生率。电阻抗成像技术(electrical impedance tomography, EIT)作为一种新兴的无创影像学技术,近年来在临床上的应用得到广泛关注,尤其在围手术期肺保护通气中的应用逐渐成熟。EIT通过实时、动态地显示肺部通气分布,为个性化同期策略的制定提供了重要的依据,显著提高了机械通气地安全性及有效性,改善了患者的预后。该文旨在探讨EIT的基本原理、优势及其在围手术期肺保护中的应用及探讨其未来的发展前景,以期为临床应用提供更多的参考和指导。

Postoperative pulmonary complications (PPCs) represent a frequent and severe challenge following surgery, particularly in patients undergoing thoracic or abdominal procedures that necessitate tracheal intubation and mechanical ventilation. PPCs typically manifest within 7 days post-surgery. Effective perioperative management, encompassing optimization of lung-protective ventilation strategies, real-time monitoring of pulmonary ventilation status, and timely interventions, can substantially decrease the incidence of PPCs. As an emerging non-invasive imaging modality, electrical impedance tomography (EIT) has garnered significant attention in recent years for its clinical applications, especially in perioperative lung-protective ventilation. EIT enables real-time and dynamic visualization of lung ventilation distribution, providing a critical foundation for developing personalized ventilation strategies. This significantly enhances the safety and efficacy of mechanical ventilation while improving patient outcomes. The aim of this article is to elucidate the fundamental principles and advantages of EIT, explore its role in perioperative lung protection, and examine its future development prospects, thereby offering additional reference and guidance for clinical practice.
