ABSTRACT
Objective To explore effect of two methods for treating extravasation of venous indwelling needles.Methods A total of 96 patients with extravasation at transfusion were randomly divided into experiment and control groups with 48 cases in each group. Magnesium sulfate wet packing was used in the control group and external application of potato chips in the experiment group.The two groups were compared in terms of time for curative effect to occur and time for recovery.Result The time for curative effect to occur and time for recovery in the experiment group were both significantly shorter than those of the control group.Conclusion External application of potato chips is effective in reducing extravasation during venous transfusion.It is simple and free from side effects.
