Abstract
A randomized open trial was undertaken to compare the antithrombotic efficacy of a low molecular weight heparin (LMWH; Sandoparin®) with that of dextran 70 in patients undergoing surgery for hip fracture. One hundred thirteen patients received LMWH once daily subcutaneously at a fixed dosage while 103 patients received intravenous dextran 70. Postoperative deep vein thrombosis (DVT) was assessed by a diagnostic algorithm using the125Iodine fibrinogen uptake test as screening and Duplex ultrasonography and/or ascending venography as confirming techniques for suspected DVT. The frequency of DVT was significantly lower in the LMWH group than in the dextran group (15.5 versus 32.6%,pp125I como prueba de tamizaje y ultrasonografía duplex Doppler y/o venografía ascendente como prueba de comprobación en los casos de sospecha de TVP. La fecuencia de TVP fue significativamente más baja en el grupo de HBPM que en el grupo de dextrán (15.5% versus 32.6%,p<0.005). La TVP proximal fue infrecuente en los dos grupos (HBPM: 2%, Dextrán: 1%). Sólo se observó un caso de embolismo pulmonar fatal en el curso de profiliaxis de 10 días en un paciente que recibió dextrán. Hubo tres casos tardíos de embolismo pulmonar: uno de carácter fatal en el grupo de dextrán en el día 14, y dos casos en el grupo de HBP (uno fatal y uno no fatal) en los días 14 y 17, respectivamente. No se presentaron complicaciones de sangrado en los dos grupos. Nuestra conclusión es que la HBPM que utilizamos es un agente seguro, que fue bien tolerado y que exhibió una acción tromboprofiláctica significativamente superior que el dextrán 70.Keywords
