Objective. To determine the application value of precise positioning for sputum expectoration in intensive care unit (ICU) hospitalized patients with pulmonary infection (PI). Methods. A total of 183 patients with PI treated in the ICUs of Shengjing Hospital of China Medical University from June 2019 to June 2020 were divided into a control group ( n = 91 ) and an observation group ( n = 92 ), all of whom received conventional drug therapy. The control group was given routine nursing intervention, based on which, the observation group was supplemented with precise positioning for sputum expectoration. The 24-hour sputum volume, respiratory rate (RR), blood gas analysis indexes, inflammatory indicators, Clinical Pulmonary Infection Score (CPIS), Modified Medical Research Council (mMRC) dyspnea scale score, and quality of life (36-Item Short-Form Health Survey, SF-36) were observed in both arms before and after intervention. The incidence of adverse reactions was counted. Results. The observation group showed better mMRC scores than the control group ( P &lt; 0.05 ). Compared with the control group, the sputum volume, RR, and CPIS score were lower, and the SF-36 score was higher in the observation group 7 days after intervention ( P &lt; 0.05 ). After intervention, the oxygen saturation (SaO2) and partial pressure of oxygen (PaO2) were higher, while the carbon dioxide partial pressure (PaCO2), C-reactive protein (CRP), procalcitonin (PCT), and leukocyte count were lower in the observation group compared with the control group ( P &lt; 0.05 ). There was no significant difference in the incidence of complications between the two arms ( P &gt; 0.05 ). Conclusion. The application of precise positioning for sputum expectoration in nursing intervention of ICU patients with PI can alleviate the severity of PI and dyspnea, reduce inflammatory reaction, and improve the quality of life of patients.
