The microcapillary infusion method (MCI) is described and compared to the pump infusion (PI) and the wick catheter methods for recording pressure in the anterior tibial muscle at rest and during exercise in 34 volunteers and in 11 patients with chronic compartment syndrome (CCS). The infusion techniques offered excellent dynamic properties in recording pressure during exercise with infusion rates exceeding 0.1 ml/hour. Infusion rates below 3.0 ml/hour in normal legs and below 1.5 ml/hour in CCS legs were found not to increase the pressure at rest during 30 minutes. The wick catheter method was found to be unsuitable in recording intramuscular pressure during exercise because of its slow response time. The MCI method had a lower compliance, a higher resonance frequency, and a shorter response time than the PI method. The muscle relaxation pressure (MRP) during exercise increased to 34.6 (SD = 5.6) mmHg in the CCS patients during exercise compared to 17.3 (SD = 4.6) mmHg in the control group. The MCI technique offers a practical tool for studying equilibrium pressures during muscle contraction and relaxation in routine clinical investigations and research.
本文描述了微毛细血管输注法（MCI），并将其与泵输注法（PI）和棉芯导管法进行比较，用于记录34名志愿者以及11名慢性骨筋膜室综合征（CCS）患者静息和运动时胫前肌的压力。在运动期间，当输注速率超过0.1毫升/小时时，这些输注技术在记录压力方面具有出色的动态特性。发现在正常腿部输注速率低于3.0毫升/小时以及在CCS腿部输注速率低于1.5毫升/小时时，在30分钟内不会增加静息压力。由于棉芯导管法响应时间较慢，发现在运动期间记录肌内压力时不适用。与PI法相比，MCI法具有更低的顺应性、更高的共振频率和更短的响应时间。与对照组运动期间17.3（标准差 = 4.6）毫米汞柱相比，CCS患者运动期间的肌肉松弛压力（MRP）增加至34.6（标准差 = 5.6）毫米汞柱。MCI技术为常规临床研究和调查中研究肌肉收缩和松弛期间的平衡压力提供了一种实用工具。
