In major trauma it is essential to immediately recognize and treat life-threatening problems and conditions. Most trauma protocols reserve the use of computed tomography for the secondary survey, as patients cannot be attended to during the examination and must be transferred from the emergency room to the CT suite. The relevant reduction in the scanning time of multidetector computed tomography (MDCT) or multislice computed tomography (MSCT) justifies its use as the major diagnostic adjunct for primary trauma survey and initial resuscitation. According to our ATLS((R))-based trauma algorithm, the multidetector scanner situated in the emergency department is utilized immediately after the correction of respiratory problems to detect causes of bleeding or intracranial hematomas. In a prospective series a total of 125 consecutive major trauma patients were evaluated. After focused sonography in trauma (FAST) and plain chest films in intubated patients, whole body MDCT was performed. By retrieving data from our trauma registry and a picture archiving and communication system (PACS), time from trauma room admission to the end of head CT scan for the entire MDCT study and calculation of multiplanar reconstruction (MPR) was analyzed. Additionally, relevant complications such as untreated tension pneumothorax or circulatory arrest during MDCT examination were recorded. The time from admission to the trauma room until completion of head CT scan without contrast was 21:12 min (median, IQR 18:13-27:52). The entire contrast-enhanced MDCT study, including pilot scan and contrast application, required 6:08 min (median, IQR 4:33-8:14) with a total scanning time of 0:59 min (median, IQR 0:55-1:03). MPR calculation of the spine and bony pelvis was performed in 11:37 min (median, IQR 8:03-16:41). A relevant life-threatening complication due to CT scanning during primary trauma survey was not observed in the 125 cases (0/125 CI 95% 0%-3%). Complete diagnostic imaging can be performed within 30 min after trauma room admission by using MDCT. During the primary survey, treatment of the patient is interrupted just for the few minutes of the CT scan and contrast application. An adequate survey of injuries can be achieved earlier and a targeted therapy can be initiated ahead of time. Integration of MDCT scanners in the primary trauma survey provides a high standard of imaging in a very short time without endangering the patient. When dealing with multiple casualties, MDCT could be used also as an accurate and time-efficient means of hospital triage to diagnose and prioritize patients and to plan further surgical interventions and intensive care.
在严重创伤中,立即识别并治疗危及生命的问题和状况至关重要。大多数创伤治疗方案将计算机断层扫描用于二次评估,因为在检查过程中无法照料患者,且患者必须从急诊室转运至CT室。多排螺旋计算机断层扫描(MDCT)或多层螺旋计算机断层扫描(MSCT)扫描时间的相应缩短,证明其可作为主要创伤评估和初始复苏的主要诊断辅助手段。根据我们基于高级创伤生命支持(ATLS)的创伤治疗流程,在纠正呼吸问题后,立即使用位于急诊科的多排探测器扫描仪来检测出血原因或颅内血肿。在一项前瞻性研究中,共评估了125例连续的严重创伤患者。在对创伤患者进行重点超声检查(FAST)和对插管患者进行胸部平片检查后,进行了全身MDCT检查。通过从我们的创伤登记系统和图像存档与通信系统(PACS)中检索数据,分析了从进入创伤室到整个MDCT检查的头部CT扫描结束的时间以及多平面重建(MPR)的计算时间。此外,还记录了MDCT检查期间未治疗的张力性气胸或循环骤停等相关并发症。从进入创伤室到无对比剂头部CT扫描完成的时间为21:12分钟(中位数,四分位间距18:13 - 27:52)。整个增强MDCT检查,包括定位扫描和对比剂注射,需要6:08分钟(中位数,四分位间距4:33 - 8:14),总扫描时间为0:59分钟(中位数,四分位间距0:55 - 1:03)。脊柱和骨盆的MPR计算用时11:37分钟(中位数,四分位间距8:03 - 16:41)。在这125例病例中,未观察到因初次创伤评估期间CT扫描导致的相关危及生命的并发症(0/125,95%置信区间0% - 3%)。使用MDCT可在进入创伤室后30分钟内完成完整的诊断性成像。在初次评估期间,仅在CT扫描和注射对比剂的几分钟内中断对患者的治疗。能够更早地对损伤进行充分评估,并提前启动针对性治疗。在初次创伤评估中整合MDCT扫描仪可在极短时间内提供高标准的成像,且不会危及患者。在处理多名伤员时,MDCT还可作为一种准确且高效的医院分诊手段,用于诊断患者并确定优先级,以及规划进一步的手术干预和重症监护。
