电阻抗断层成像用于围手术期呼吸管理的研究进展

Research progress on electrical impedance tomography for perioperative respiratory management

电阻抗断层成像(EIT)是一种非侵入性的成像技术,它利用电流通过人体时电阻抗的变化来生成胸部横截面图像。在围手术期的呼吸管理中,EIT提供了一种实时、连续监测肺部通气和灌注状态的方法,指导围术期患者的呼吸管理,包括指导慢性阻塞性肺疾病(COPD)和哮喘患者的围术期用药、特殊人群术中个体化呼气末正压(PEEP)设置、儿童围手术期肺保护、预测术后肺部并发症等。EIT在围手术期的应用帮助临床医生更精确地管理患者呼吸状态,减少并发症,改善预后。通过实时监测和指导个体化治疗,EIT提高了围手术期呼吸管理的安全性和有效性,已经成为手术室中不可或缺的一部分。本文对EIT在围手术期的应用进行综述,以期为EIT的临床应用提供参考。

Electrical impedance tomography(EIT)is a non-invasive imaging technique that generates cross-sectional images of chest by measuring changes in impedance as electric currents passing through human body.In perioperative respiratory management,EIT provides a real-time,consecutive monitoring of lung ventilation and perfusion status,guiding respiratory management of perioperative patients including medication for COPD and asthma,personalized PEEP settings for specific patient populations,lung protection for pediatric perioperative cases,and predicting postoperative pulmonary complications.Application of EIT in the perioperative period helps clinicians to manage patient respiratory status more accurately,reduces complications and improves outcomes.Through real-time monitoring and individualized treatment guidance,EIT enhances the safety and effectiveness of perioperative respiratory management,becoming an essential part of the operating room.This review summarises the application of EIT in the perioperative period,aiming to provide reference for the clinical application of EIT.
