RESUMO
Objective Toobservetheeffectofperioperativeuseoflowmolecularheparin(LMH)forpreventinglowerlimbdeep vein thrombosis(DVT ) in elderly hip peripheral fracture .Methods 105 cases of elderly hip peripheral fracture from July 2007 to July 2011 were divided into the LMH group(65 cases) and the conventional treatment group(40 cases) .The two groups were per-formed the physical therapy for preventing lower limb DVT .The LM H group was added with LM H for preventing DVT .The sta-tuses of DVT occurrence and the coagulation related indicators were compared between the two groups .Results In the LM H group ,the thrombus events happened in 4 cases ,accounting for 6 .15% .In the conventional treatment group ,thrombosis occurred in 13 cases ,accounting for 32 .5% .The difference between the two groups had statistical significance (P<0 .05) .Hemoglobin on post-operative 1 ,10 d was obviously improved ,the difference had statistical significance(P<0 .05) .Conclusion Using LMH has rela-tively ideal effect for preventing lower limb DVT in elderly hip peripheral fracture .
