Traumatic pneumothorax (PTx) is common in chest trauma. Its incidence ranges between 10 and 28%. Chest X-ray (CXR) is the traditional imaging for the potential traumatic PTx, while CT chest is considered the gold standard diagnostic tool. However, it requires that the patient to be transferred from the Emergency Department (ED) with its resuscitative facilities. Chest US (E-FAST) has emerged as a sensitive tool that can be used on bedside basis with much higher sensitivity than CXR. The objective of this study was to compare between accuracy and usefulness of the bedside US chest and CT chest in the diagnosis of traumatic PTx, as well as its ability to quantify its size. This was a prospective clinical study that included two hundred patients who have been admitted to the ED. The inclusion criteria included any patient with chest trauma. Exclusion criteria included patients with clinical surgical emphysema, patients with life threatening PTx, and patients who did not undergo CT chest. Forty-seven hemithoraces were proved positive for PTx by CT chest, while forty-five hemithoraces out of those 47 were confirmed by bedside chest US. The sensitivity for chest US is 95.74% in detection of traumatic PTx. No false-positive cases were diagnosed. All of the forty-five hemithoraces diagnosed by chest US have been confirmed by CT scan making a specificity of 100%. Chest US is a useful rapid diagnostic tool in the diagnosis and quantification of the traumatic PTx at ED. It avoids the delay in transportation of the critically ill patients to perform CT chest.

床旁胸部超声与胸部CT诊断外伤性气胸的对比研究

创伤性气胸 (PTx) 在胸部外伤中很常见。其发生率在 10% 到 28% 之间。胸部 X 射线 (CXR) 是潜在创伤性 PTx 的传统成像,而胸部 CT 被认为是金标准诊断工具。但是,它要求患者从急诊科 (ED) 及其复苏设施转移。胸部超声 (E-FAST) 已成为一种敏感工具,可在床边使用,其灵敏度远高于 CXR。本研究的目的是比较床边超声胸部和 CT 胸部在诊断创伤性 PTx 方面的准确性和实用性,以及量化其大小的能力。这是一项前瞻性临床研究,其中包括 200 名已入住 ED 的患者。纳入标准包括任何胸部外伤患者。排除标准包括临床手术肺气肿患者、危及生命的 PTx 患者和未接受胸部 CT 的患者。47 个半胸胸被 CT 胸部证实为 PTx 阳性,而这 47 个半胸胸中的 45 个被床边胸部 U​​S 证实。胸部超声检测创伤性 PTx 的灵敏度为 95.74%。没有诊断出假阳性病例。胸部 US 诊断的所有 45 个半胸都已通过 CT 扫描确认,特异性为 100%。胸部超声是一种有用的快速诊断工具,可用于诊断和量化 ED 的创伤性 PTx。避免了耽误重症患者进行胸部CT的转运。和未接受胸部 CT 的患者。47 个半胸胸被 CT 胸部证实为 PTx 阳性,而这 47 个半胸胸中的 45 个被床边胸部 U​​S 证实。胸部超声检测创伤性 PTx 的灵敏度为 95.74%。没有诊断出假阳性病例。胸部 US 诊断的所有 45 个半胸都已通过 CT 扫描确认,特异性为 100%。胸部超声是一种有用的快速诊断工具,可用于诊断和量化 ED 的创伤性 PTx。避免了耽误重症患者进行胸部CT的转运。和未接受胸部 CT 的患者。47 个半胸被 CT 胸部证实为 PTx 阳性,而这 47 个半胸中的 45 个被床边胸部 U​​S 证实。胸部超声检测创伤性 PTx 的灵敏度为 95.74%。没有诊断出假阳性病例。胸部 US 诊断的所有 45 个半胸都已通过 CT 扫描确认,特异性为 100%。胸部超声是一种有用的快速诊断工具,可用于诊断和量化 ED 的创伤性 PTx。避免了耽误重症患者进行胸部CT的转运。没有诊断出假阳性病例。胸部 US 诊断的所有 45 个半胸都已通过 CT 扫描确认,特异性为 100%。胸部超声是一种有用的快速诊断工具,可用于诊断和量化 ED 的创伤性 PTx。避免了耽误重症患者进行胸部CT的转运。没有诊断出假阳性病例。胸部 US 诊断的所有 45 个半胸都已通过 CT 扫描确认,特异性为 100%。胸部超声是一种有用的快速诊断工具,可用于诊断和量化 ED 的创伤性 PTx。避免了耽误重症患者进行胸部CT的转运。
