静动脉二氧化碳分压差在重型颅脑创伤患者治疗中的应用

重型颅脑创伤（sTBI）作为临床常见的危重症，发病率逐年上升，且sTBI患者常预后不佳。近年的研究发现，静动脉二氧化碳分压差（Pcv-aCO2）对患者早期病情评估、指导调整治疗方案、预测疾病结局等方面有较好的临床应用价值。本文对近年来Pcv-aCO2在sTBI治疗中的应用进行综述。

The severe traumatic brain injury is critical with increasing incidence yearly. Patients with sTBI often have poor prognosis. Recent studies have found that central venous-to-arterial carbon dioxide partial pressure difference（Pcv-aCO2） has good clinical application value for assessment of patients' early condition, adjustment of treatment plan and predicting prognosis. This paper reviews the application of Pcv-aCO2 in the treatment of sTBI.
