The purpose of this study was to assess the effect of external venous support on edema and pain in the saphenous graft leg of patients who had coronary artery bypass graft surgery (CABG) 5 days and 1 month after surgery. Fifty-six patients who had CABG surgery were randomly assigned to the experimental (n = 24) or control (n = 32) group. Subjects in the experimental group wore graded compression support hose. Edema was assessed by using ankle, calf, and thigh circumference measurements. Pain was measured on a visual analog scale. Hose were effective in preventing edema during hospitalization, but results at 1 month were inconclusive. There was no difference in leg pain for experimental and control subjects. That a number of patients in the experimental group were unable to complete the study suggests that off-the-shelf, thigh-high support hose may not be useful for individuals with disproportionately large thighs. Further investigation of the long-term effects of support hose is warranted.
本研究的目的是评估体外静脉支持对冠状动脉旁路移植术（CABG）术后5天及1个月的患者隐静脉移植肢体水肿和疼痛的影响。56例行CABG手术的患者被随机分为实验组（n = 24）或对照组（n = 32）。实验组的受试者穿着分级加压支持袜。通过测量脚踝、小腿和大腿周长来评估水肿情况。使用视觉模拟量表测量疼痛程度。支持袜在住院期间能有效预防水肿，但1个月时的结果尚无定论。实验组和对照组受试者的腿部疼痛没有差异。实验组中有一些患者无法完成研究，这表明现成的大腿高支持袜可能对大腿比例过大的个体无用。有必要进一步研究支持袜的长期效果。
