【摘要】 目的 探讨高压氧（HBO）对肺空气栓塞（PAE）患者的临床治疗效果及作用机制，为临床早期救治PAE患者提供循证依据与实践参考。方法 患者入院后经多学科会诊明确诊断，紧急采用HBO治疗方案；出舱后给予补液支持、生命体征严密监测等综合干预。结果 HBO治疗1次后，患者胸闷、气短、头昏等症状完全缓解，复查肺动脉CT提示肺动脉、右心房及右心室内气泡完全消失；随访1个月，患者未出现任何后遗症及异常表现。结论 HBO治疗可快速缩小并消除肺内气泡阻塞，改善组织缺氧状态，对PAE早期救治具有确切疗效，联合多学科协作与综合干预措施可显著提高救治效果。更多还原

【Abstract】 Objective This study aimed to investigate the clinical therapeutic effects and mechanisms of hyperbaric oxygen(HBO) therapy in patients with pulmonary air embolism(PAE),so as to provide evidence-based guidance and practical reference for the early clinical management of PAE patients.Methods The patient diagnosed through multidisciplinary consultation upon admission was urgently underwent hyperbaric oxygen(HBO) therapy for air embolism.Following the HBO session,comprehensive interventions such as fluid resuscitation support and close monitoring of vital signs were administered.Results After a single session of HBO therapy,the patient’s symptoms,including chest tightness,shortness of breath and dizziness,were completely relieved.The following pulmonary CT angiography revealed complete resolution of air bubbles in the pulmonary arteries,right atrium,and right ventricle.During one-month follow-up period,the patient did not exhibit any sequelae or abnormal manifestations.Conclusion HBO therapy can rapidly reduce and eliminate air bubble obstruction,thereby improving tissue hypoxia.It demonstrated definitive efficacy in the early treatment of PAE,and when combined with multidisciplinary collaboration and comprehensive interventions,significantly enhanced patient’s prognosis.更多还原
