This study was designed to identify the most effective underbody position when using the patient's own body weight as an infusion device. Twenty volunteers had an air-less 500 ml bag of saline located at various under-body positions. Mean pressures and flow rates through a 14G cannula were measured in vitro at room temperature. Locating the fluid bag at the buttock cleft delivered the highest mean flow rate at 135 ml/min. This underbody position may provide flow rates sufficient to achieve the clinical aim of fluid resuscitation in the military pre-hospital environment.
本研究旨在确定在使用患者自身体重作为输液装置时最有效的身体下方位置。20名志愿者将一个500毫升无气生理盐水袋放置在身体下方的不同位置。在室温下于体外测量通过14G套管的平均压力和流速。将输液袋置于臀裂处时，平均流速最高，为135毫升/分钟。这种身体下方位置可能提供足以实现军事院前环境中液体复苏临床目标的流速。
