[Risk early warning and multimodal prevention of postoperative venous thromboembolism for hip fractures].
OBJECTIVE
To study the efficacy and safety of multimodal prevention of postoperative venous thromboembolism for hip fractures.


METHODS
From March 2009 to July 2011, preoperatively, patients were assigned to two groups on the basis of an assessment of their risk factors. One hundred and twelve patients were considered to be low risk, involving 47 males and 65 females,with an average age of (72.40 +/- 13.29) years ranging from 42 to 88,and were managed with aspirin (100 mg once daily for 14 days) as well as intermittent gasing compression devices. Twenty-six patients were considered to be high risk, involving 12 males and 14 females with an average age of (78.50 +/- 12.76) years ranging from 65 to 84,and were managed with low-molecular-weight heparin (0.4 ml,subcutaneous injection once daily for 14 days) and intermittent gasing compression. All patients were underwent Doppler ultrasonography within 24 hours before hospital discharge. All patients were followed-up for 3 months postoperatively. The incidence of deep venous thrombosis of lower limb, pulmonary embolism, gastrointestinal hemorrhage were recorded.


RESULTS
Overall, there were no fatal pulmonary embolism, 1 case of symptomatic pulmonary emboli in low risk group, and none were detected in the high-risk group. Deep venous thrombosis was detected in association with 6 (6.25%) of the 112 procedures in the low-risk group and 2 (7.69%) of the 26 operations in the high-risk group. Paitents were selected in opened reduction and internal fixation, the quantity of bleeding, decrease of hemoglobin, hematoma rate, and gastrointestinal hemorrhage rate of low risk group were (538.10 +/- 390.20) ml, (30 +/- 19) g/L, 0, and 1 (1.03%) respectively; those of the high-risk group were (585.95 +/- 403.96) mL, (32 +/- 20) g/L,1 (4.76%), (4.76%), there were no significant different between the two groups, all P > 0.05.


CONCLUSIONS
There were no statistic significances between the aspirin as well as intermittent gasing compression devices and the low-molecular-weight heparin and intermittent gasing compression in preventing venous thromboembolism (VTE) in postoperative postoperative venous thromboembolism for hip fractures. However, there are potential advantages to reduce complications of bleeding and cardiovascular disease. Multimodal prevention of postoperative venous thromboembolism can protect postoperative patients with hip fractures.
