				        	Objective To investigate the relationship between bed rest time and development of prethrombotic state in the elderly patients with hip fracture.Methods One hundred and sixty-six patients who stayed in bed after hip fracture,aged ≥65 yr,were divided into 5 groups according to the bed rest time on admission to hospital:bed rest time < 24 h (Ⅰ group,n =61),bed rest time 24-48 h (Ⅱ group,n =29),bed rest time 3-6days (Ⅲ group,n =29),bed rest time 7-14 days (Ⅳ group,n =34),and bed rest time > 14 days (Ⅴ group,n =13).Venous blood samples were collected to measure the platelet count,coagulation function,and concentrations of plasma D-Dimer and serum α-granule membrane protein 140 (GMP-140).The development of abnormality in each index was recorded.The development of deep vein thrombosis in both lower extremities was diagnosed using color Doppler ultrasound in D-Dimer-positive patients.Results Compared with group Ⅰ,the abnormal rate of fibrinogen (Fib) and D-Dimer and serum GMP-140 concentrations were significantly increased in Ⅱ and Ⅲ groups,the abnormal rate of platelet count,Fib and D-Dimer and serum GMP-140 concentrations were increased in lⅣ group,and the abnormal rate of platelet count was increased,and no significant change was found in the serum GMP-140 concentrations and abnormal rate of Fib and D-Dimer in Ⅴ group.Compared with group Ⅱ,the serum GMP-140 concentrations were significantly increased in Ⅲ and Ⅳ groups,the abnormal rate of Fib and D-Dimer was increased in Ⅳ group,and no significant change was found in the abnormal rate of Fib and DDimer in Ⅲ group.The abnormal rate of platelet count was significantly lower in Ⅳ group than in Ⅲ group.Color Doppler Ultrasonography showed no sign of deep vein thrombosis.Conclusion For the elderly patients with hip fracture,the possibility of pre-thrombotic state developed is increased when the bed rest time is more than 24 h,and the patients were classified as high-risk patients when the bed rest time is more than 3 days.
