The use of high resolution ultrasound is an established diagnostic method. A disadvantage of current high end systems is that transporting the device into the operating theatre or an intensive care unit requires time and logistic effort. We report results of an evaluation of a portable ultrasound system in the diagnosis and treatment of the head and neck area. Indications and value of a portable device in the clinical setting of an operation theatre and intensive care unit were assessed.
Within a period of 5 months, 48 patients were included in this prospectively designed study using a portable ultrasound system with B-scan/color Doppler mode (SonoSite TITAN, Firma SonoSite® Germany) and an 7.5 MHz broadband linear array transducer. Two experienced physicians recorded the location and examination conditions, imaging mode, time expenditure, indication and diagnosis. The examiner also commented about whether the use of a portable laptop system considerably improved the therapy decision. The analysis included descriptive statistics for interpretation of the results.
The most frequent use of the ultrasound system was the pre- or intrasurgical "pinpointing" of tumours in the soft tissues of the neck or in salivary glands. The average time for the examination was 6 min. In 79 % of the cases, the examiner stated a definite improvement of the therapy decision through the use of the portable ultrasound.
We could demonstrate that a portable ultrasound system is a time-saving, economic and ubiquitously applicable method of imaging. Diagnosis and surgical planning are optimized. Thus, in larger hospitals and clinics, a portable ultrasound device is a logical complement to a stationary unit.
高分辨率超声的应用是一种既定的诊断方法。当前高端系统的一个缺点是将设备运送到手术室或重症监护病房需要时间和后勤保障。我们报告了对一种便携式超声系统在头颈部区域诊断和治疗中的评估结果。评估了便携式设备在手术室和重症监护病房临床环境中的适应症和价值。
在5个月的时间内，48例患者被纳入这项前瞻性设计的研究，使用具有B超/彩色多普勒模式的便携式超声系统（SonoSite TITAN，德国SonoSite®公司）和7.5MHz宽带线性阵列换能器。两名经验丰富的医生记录了位置和检查条件、成像模式、时间花费、适应症和诊断。检查者还对使用便携式笔记本电脑系统是否显著改善治疗决策发表了评论。分析包括用于结果解释的描述性统计。
超声系统最常见的用途是在颈部软组织或唾液腺肿瘤的术前或术中“定位”。检查的平均时间为6分钟。在79%的病例中，检查者表示通过使用便携式超声，治疗决策有了明显改善。
我们可以证明，便携式超声系统是一种省时、经济且普遍适用的成像方法。诊断和手术规划得到了优化。因此，在大型医院和诊所中，便携式超声设备是固定设备的合理补充。
