| 中文摘要: |
| 血管外肺水（EVLW）是评估肺水肿的重要指标，与死亡率独立相关，积极治疗可改善患者预后。CT和MRI可准确评估肺水肿，但不适用于实时监测；而单次热稀释需要重复校准，易出错。由于空气的高声阻抗，传统上认为肺部不适于超声检查。超声B线是识别EVLW及观察其动态变化的灵敏方法，伴随研究的深入，超声越来越多地用于评估EVLW，对于诊治肺水肿具有重要意义。 |
| 英文摘要: |
| Extravascular pulmonary water (EVLW) is an important index for evaluation of pulmonary edema. EVLW is independently associated with mortality, and positive treatment can improve the prognosis of patients with pulmonary edema. CT and MRI can accurately assess hydropneumonia, but not suitable for real-time measurement. Single thermal dilution technique requires repeated calibration, which is prone to errors. Due of the high acoustic impedance of air, the lung is traditionally considered not suitable for ultrasonic examination. However, the recognition of ultrasound artifacts in diseased lungs promoted the development of ultrasound. Ultrasound B line is a useful and sensitive way for judging the presence and observing dynamic changes of EVLW. With the in-depth study of B line, ultrasound has been more and more applicated for evaluation on EVLW, therefore having great significances for diagnosis and treatment of pulmonary edema. |
