This study was undertaken to determine what optimal levels of suction pressure were necessary to provide good drainage volume and obliteration of any dead space and also to determine the prevalence of clotting and complications secondary to various levels of suction pressure. The patients were grouped by their degree of nutritional depletion, prior radiation exposure, the types of surgical procedures undergone, and the results of tests using four levels of suction pressure. Three of the suction pressure values were obtained with a wall suction and one was obtained using a portable closed system. All wall suction pressure levels were certainly comparable with the portable unit. However, the portable unit provided continuous suction pressure when the patients were ambulatory and was not associated with any statistically significant increase in wound complications or equipment failure.
本研究旨在确定提供良好引流量和消除任何死腔所需的最佳吸引压力水平，并确定不同吸引压力水平继发凝血和并发症的发生率。患者按营养消耗程度、既往放疗史、所接受的手术类型以及使用四种吸引压力水平的测试结果进行分组。其中三种吸引压力值通过墙壁吸引获得，一种通过便携式封闭系统获得。所有墙壁吸引压力水平肯定与便携式装置相当。然而，便携式装置在患者活动时提供持续吸引压力，且与伤口并发症或设备故障的任何统计学显著增加无关。
