Effect observation of different indwelling depths of venous indwelling needle

Objective To explore the effect of venous indwelling needle's different indwelling depths. Methods 200 cases of inpatients who needed venous indwelling needle were randomly divided into two group,namely control group,observation group. In control group,the outer casing of venous indwelling needle were fixed after completely implanted. In observation group,the outer casing of venous indwelling needle were fixed with 1 ~ 2 mm exposed. Compare the unobstructed degree of transfusion,the incidence of phlebitis,indwelling time and patients' satisfaction. Results The observation group's unobstructed degree of transfusion in the second day and the third day is better than that of the control group( P 0. 05). The indwelling time of observation group is longer than that of control group.( P 0. 05). The incidence rate of grade one phlebitis in observation group is lower than that in control group( P 0. 05). Patients of observation group have higher satisfaction than patients in control group( P 0. 05). Conclusion The method that outer casing of venous indwelling needle is fixed with 1 ~ 2mm exposed can improve the unobstructed degree of transfusion,extends the indwelling time and finally improve patients' satisfaction.
