Comparison of compression stocking with elastic bandage in reducing postoperative edema in coronary artery bypass graft patient

The removal of the saphenous veins in coronary artery bypass graft (CABG) surgery may cause leg edema. Compression therapy is often used to prevent postoperative edema. The objective of this study was to compare the efficacy of medical compression stocking (TED) and elastic bandage-type on donor limbs after CABG. The peripheries of lower limbs were measured at four regions (A: end of tarsal bones, H: heel , B: immediately above the ankle, C: largest circumference of the calf) at admission in 295 patients how CABG candidates and differences in these measurement points at discharge compared to measurements at admission time were calculated. The difference was considered as a measure of the effectiveness of two types of compression to prevent postoperative edema in donor limbs after CABG. The alterations of 396 donor limbs of 295 patients were examined after CABG at admission and discharge time. In 101 patients veins for graft were taken from both lower limbs. After analysis, if subjects had worn TED stockings, the peripheries of donor limbs at discharge were less than at admission time in the A and H regions compared to elastic bandage group (P_A=0/009), (P_H=0/012). The conclusion reached was that using the kind of knee length compression stocking (TED stocking , Kendall Co.) is more effective edema at foot and heel regions in donor limbs after CABG than elastic bandages.
