Infusion lines (to elevate intracompartmental pressure experimentally) and wick catheters (to monitor the pressure produced) were inserted into hind-limb muscle compartments in twenty-six dogs. A padded plaster cast was then applied. The effect of the cast on intracompartmental pressure and volume and the effect of first splitting the cast and then cutting the padding were determined. Three different padding were used: dry Webril, Webril soaked in blood and Betadine (povidone-iodine), and Webril soaked in blood and Betadine and then dried. The cast was found to restrict expansion of the compartment volume by approximately 40 per cent. The most significant reductions in pressure in all groups occurred after the cast was cut and spread (mean reduction, 65 per cent). An additional pressure reduction of 10 to 20 per cent occurred after cutting the Webril. After removal of the cast, all limbs maintained some residual elevation of the intracompartmental pressure.
This study demonstrates the need in clinical practice for continued evaluation and monitoring of a limb even after the cast has been completely removed because of signs and symptoms of a compartmental syndrome.
在26只狗的后肢肌肉间隙插入输液管（用于实验性升高间隙内压力）和棉芯导管（用于监测产生的压力）。然后应用带衬垫的石膏管型。确定了管型对间隙内压力和容积的影响，以及先将管型劈开然后切开衬垫的影响。使用了三种不同的衬垫：干燥的弹力绷带、浸泡在血液和碘伏（聚维酮碘）中的弹力绷带，以及浸泡在血液和碘伏中然后干燥的弹力绷带。发现管型使间隙容积的扩张受限约40%。所有组中，在管型被切开并撑开后压力出现最显著降低（平均降低65%）。切开弹力绷带后压力又额外降低10%至20%。去除管型后，所有肢体的间隙内压力仍保持一定程度的残余升高。
本研究表明，在临床实践中，即使石膏管型已完全去除，由于存在骨筋膜室综合征的体征和症状，仍需要对肢体进行持续评估和监测。
