Effect of PDCA Evidence-Based Nursing Practice on Arterial Blood Gas Analysis in the Respiratory Department

Abstract

<i>Objective</i> To explore the effect of PDCA evidence-based nursing intervention on arterial blood gas analysis in the respiratory department. <i>Methods</i> Sixty patients who underwent blood gas analysis in our hospital from February 2021 to March 2021 were selected as the control group; while the same number of patients who underwent blood gas analysis from July 2021 to August 2021 were selected as the observation group to implement PDCA evidence-based nursing practice. The effects of one-time success rate, qualified specimen rate, incidence of redness, swelling and ecchymosis at puncture point, sample turnover time and nurses' knowledge level were compared between the two groups. <i>Results</i> The success rate of one-time puncture and the qualified rate of specimens in the observation group were higher than those in the control group (P < 0.05). Meanwhile, the incidence of redness, swelling and ecchymosis at the puncture point and the turnover time of specimens in the observation group were lower than those in the control group (P < 0.05). After the implementation of the improvement plan, the nurses' knowledge levels in the observation group were significantly increased compared with the control group (P < 0.05). <i>Conclusion</i> PDCA evidence-based nursing practice can effectively improve the knowledge level of nurses, shorten the sample turnover time, increase the success rate of one-time puncture and the qualified rate of samples, reduce the incidence of adverse events such as redness, swelling and ecchymosis at the puncture point, and improve the quality of clinical nursing.
