背景。晚间腿部水肿是坐立后发生的一种生理现象。本研究的目的是探讨哪种压缩压力是防止腿部肿胀所必需的。在12名志愿者中，分别在早上和7小时后测量两条小腿的体积，差异被定义为晚间水肿（mL）。该过程进行了4天，在此期间，受试者仅按随机顺序在一条腿上交替穿着不同压缩程度的膝盖以下丝袜。使用HATRA装置评估压缩压力。非压缩组夜间平均左侧水肿62.4 mL，右侧水肿94.4 mL （ns）。晚间水肿明显减少，光支撑丝袜为40.3 mL， A级压缩为-34.1 mL， I级压缩为-39.6 mL， II级压缩为-59.1 mL。主要是施加超过10 mmHg压力的长统袜改善了主观症状。压力范围在11到21毫米汞柱之间的小腿长度的压缩袜能够减少或完全防止夜间水肿，因此可能建议长时间坐着或站着的职业的人使用。
BACKGROUND. Evening edema of the legs is a physiologic phenomenon occurring after sitting and standing.OBJECTIVE. The objective of this study was to investigate which compression pressure is necessary to prevent leg swelling.METHODS. In 12 volunteers, the volume of both lower legs was measured in the morning and 7 h later, the difference being defined as evening edema (mL). The procedure was carried out for 4 days, in which the subjects wore below-knee stockings of different compression levels alternatively on one leg only in a random order. Compression pressure was assessed using the HATRA device.RESULTS. The average evening edema of the noncompressed legs was 62.4 mL on the left side and 94.4 mL on the right side (n.s.). Evening edema was significantly reduced to 40.3 mL by light support stockings, to -34.1 mL by compression class A, to -39.6 by compression class I, and to -59.1 mL by compression class II. Mainly stockings exerting a pressure above 10 mmHg improved subjective symptoms.CONCLUSION. Calf-length compression stockings with a pressure range between 11 and 21 mmHg are able to reduce or totally prevent evening edema and may therefore be recommended for people with a profession connected with long periods of sitting or standing.
