Abstract: Objective Pulmonary infection is a common complication in patients with severe traumatic brain injury, which seriously affects the prognosis of patients.Not only do we need to improve the patient's condition, but also to take scientific measures to reduce the incidence of pulmonary infection.The paper supplies control circle (QCC) activities to explore the value of nursing care after tracheostomy in patients with severe craniocerebral injury. Methods Quality control circle activity was set up and the activity theme was established in 36 patients with tracheostomy after the injury and 40 subjects serving as control group.Pneumonia rate was compared between QCC activities group and control group.Time of antibiotic use and duration of fever in patients with pneumonia were also compared after the injury between two groups. Results In the control group, including 34 cases of patients with pulmonary infection, infection rate was 85%.There were 19 cases of pulmonary infection in QCC group, accounting for 52.78%, which was statistically significant compared with the control group (χ²=9.321, P=0.002, P < 0.05).For patients with pneumonia, the QCC activities significantly shortened the time of antibiotic use and duration of fever (P < 0.05). Conclusion The results indicated that QCC activity not only reduced the incidence of pneumonia after tracheostomy and pulmonary infection which was effectively controlled, but also may be helpful for improving the skills as a quality management tool, thus worthy of promotion and use in clinical practice.
