The indication for surgical treatment of the chronic exertional compartment syndrome is evaluated by measuring intracompartmental pressures. The validity of these invasive intracompartmental pressure measurements are increasingly questioned in the absence of a standardized test protocol and uniform cut-off values. The aim of the current study was to test compartment pressure monitors and needles for uniformity, thereby supporting the physician’s choice in the selection of appropriate test materials. A compartment syndrome was simulated in embalmed above-knee cadaveric leg specimen. Four different terminal devices (Compass manometer, Stryker device, Meritrans transduce, and arterial line) were tested with 22 different needle types. Legs were pressurized after introduction of the four terminal devices in the anterior compartment, using the same needle type. Pressure was recorded at a 30-second interval for 11 minutes in total. Before and after pressurization, the intravenous bag of saline was weighed. The simulation of a compartment syndrome resulted in intracompartmental pressure values exceeding 100 mmHg in 17 of the 22 legs (77%). In the other five legs, a smaller built-up of pressure was seen, although maximum intracompartmental pressure was in between 70 and 100 mmHg. The intraclass correlation coefficient was above 0.700 for all possible needle types. Excellent to good resemblance was seen in 16 out of 22 instrumental setups (73%). The mean volume of saline infusion required in runs that exceeded 100 mmHg (309 ± 116 ml) was significantly lower compared to the legs in which 100 mmHg was not achieved (451 ± 148 ml; p = 0.04). The intracompartmental pressure recordings of the four terminal devices were comparable, when tested with a standardized pressurization model in a human cadaver model. None of the included terminal devices or needle types were found to be superior. The results provide evidence for more diverse material selection when logistic choices for intracompartmental pressure measurement devices are warranted. Level IV.

可用于测量室内压力的设备的适用性：尸体研究

慢性劳力性筋膜室综合征的手术治疗指征是通过测量筋膜内压力来评估的。在没有标准化的测试方案和统一的临界值的情况下，这些侵入性室内压力测量的有效性受到越来越多的质疑。当前研究的目的是测试隔室压力监测器和针头的均匀性，从而支持医生选择合适的测试材料。在经过防腐处理的膝上尸体腿标本中模拟了隔室综合征。用 22 种不同的针头类型测试了四种不同的终端设备（罗盘压力计、Stryker 设备、Meritrans 传感器和动脉导管）。将四个终端装置引入前室后，腿部被加压，使用相同的针类型。以 30 秒的间隔记录压力总共 11 分钟。加压前后，对静脉注射的生理盐水袋进行称重。隔室综合征的模拟导致 22 条腿中有 17 条 (77%) 的室内压力值超过 100 mmHg。在其他 5 条腿中，可以看到较小的压力积聚，尽管最大室内压力在 70 到 100 mmHg 之间。所有可能的针头类型的组内相关系数均高于 0.700。在 22 种乐器设置中的 16 种（73%）中发现了极好的相似性。与未达到 100 mmHg 的腿部相比，超过 100 mmHg (309 ± 116 ml) 的跑步所需的平均盐水输注量显着降低 (451 ± 148 ml; p = 0.04)。当在人体尸体模型中使用标准化加压模型进行测试时，四个终端设备的室内压力记录具有可比性。没有发现包含的终端设备或针头类型是优越的。当需要对室内压力测量设备进行逻辑选择时，这些结果为更多样化的材料选择提供了证据。第四级。
