Investigation And Intervention On Clinical Intravenous Therapy

Objective: The objective of this paper is to investigate the present situation of clinical intravenous therapy, analyze the existing problems, carry out nursing intervention and evaluate intervention effect to explore the focus of the nursing quality improvement of clinical intravenous therapy, put the Standard for Intravenous Therapy Technical Operation into practice and ensure patients’ safety.Methodology: By cluster sampling, self-designed questionnaires and shooting the photos of infusion tubes, this paper collected the data concerning intravenous therapy of 1,015 inpatients from 9:00 to 11:00 on July 10, 2014, set as the pre-intervention group, in 29 clinical departments of a Class A tertiary comprehensive hospital. Again, after the move, 1,039 cases in the same hospital were taken from 9:00 to 11:00 on February 3, 2015, set as the post-intervention group. The research project was focused on five aspects: infusion puncture tool selection, puncture site selection, catheter fixation, catheter maintenance and complications related to partial puncture intravenous infusion. A statistical analysis was made according to the data collected to evaluate the intervention effect.Results:1 The comparison of the use ratio of the tools for clinical intravenous transfusion puncture between the pre-intervention group and the post-intervention group: No significant difference was found in the pre- and post-intervention PICC, CVC and infusion port patients( c2 =0.009,1.035,0.041,P = 0.309,0.925,0.839). As to the use rate of the disposable infusion steel needle and the peripheral vein indwelling needle, compared with the pre-intervention group, there was a striking difference( c2 = 26.844,23.289,P﹤0.001).2 Infusion tool selection: The acceptance rate of the pre-intervention infusion tool selection was 93.2%, and that of the post-intervention infusion tool selection was 96.5% with no dramatic difference between them( c2 =3.521,P > 0.05).3 Puncture site selection: The acceptance rate was 88.8% in the pre-intervention group and was 94.8% in the post-intervention group, with a significant difference between them(c2 =24.893,P﹤0.001). The acceptance rate on CVC, PICC and infusion ports for both pre- and post-intervention groups was 100%. A dramatic increase took place in the pass rate of the post-intervention selection on the disposable infusion steel needle and the peripheral vein indwelling needle.4 Catheter fixation: The pre-intervention pass rate was 83.2% and the post-intervention pass rate was 94.8%with a significant difference between them( c2 =71.439,P﹤0.001).5 Catheter maintenance: The pre-intervention pass rate was 91.6% and the post-intervention pass rate was 97.5% with a striking difference between them( c2 =34.630,P﹤0.001).6 Complications related to local puncture intravenous transfusion: The pre-intervention rate of complications was 4.4% and the post-intervention rate of complications was 2.3% with a significant difference between them( c2 =7.132,P﹤0.05).Conclusions:1 The investigation on clinical intravenous therapy showed that this hospital’s intravenous infusion tool selection and central intravenous puncture site selection conformed to the requirements of the Standard. But there is room to improve in some details.2 Thanks to the nursing intervention measures, a notable improvement has been made on clinical intravenous infusion therapy in catheter fixation, catheter maintenance, peripheral venous duct puncture site selection, and complications related to partial puncture intravenous infusion.
