Deep-vein thrombosis (DVT) is a serious problem that affects millions of people annually. Prophylaxis against (DVT) following major orthopaedic surgery can save life. Proper application of the prophylactic regimen by nursing and the interdisciplinary team can be a major key in affecting the outcome of the orthopaedic patient. Prevention of deep-vein thrombosis (DVT) and its complication, pulmonary embolism (PE), is a primary focus of the daily care of the postoperative orthopaedic patient. Compression stockings improve the return of blood from the veins back to the heart and reduce the occurrence of deep vein thrombosis as well. The aim of this study is to determine the effect of using elastic compression stockings in preventing deep vein thrombosis after hip surgery in orthopedic units at Zagazig university hospitals. The sample consists of 80 adult patients admitted to orthopaedic units at Zagazig University Hospitals. Patients who were scheduled for hip surgery and accepted to participate in the study were the subjects of the study. Both gender were included, Patients having the following criteria were excluded such as massive edema/swelling of leg, pulmonary edema or (cardiac failure), severe peripheral arterial disease, severe peripheral neuropathy, major leg deformity, and certain types of skin disease (e.g. weeping skin lesions/dermatitis). The selected sample was divided randomly into two equal groups (control group and study group) Significant changes were detected between the two groups.
