RÉSUMÉ
Objective To investigate the effects of the routine needle-withdrawing method and improved needle-withdrawing method? Methods One hundred patients undergoing intravenous transfusion were randomized into the control group and the improvement group (255 times of transfusion ), with 50 cases in each group: the former was treated with routine needle-withdrawing method and the latter with the improved method? Complications after needle-withdruing were compared between the two groups? Result The rates of pains, subcutaneous bleeding or bleeding at the puncture points in the improvement group were all significantly lower than those of the control group (P<0?001)? Conclusion The improved needle-withdrawing method is effective in reducing the rate of post-withdrawal complications and improve the safety of intravenous transfusion?
