The Effect of Prophylactic Application of Noninvasive Ventilator in High Risk Patients after Cardiac Surgery and Improvement of Nursing Intervention

Objective: To investigate the efficacy, safety and nursing improvement of noninvasive positive pressure ventilation (NPPV) in high-risk patients with acute respiratory failure after cardiac surgery. Methods: From September 2018 to October 2019, high-risk patients who may develop acute respiratory failure after cardiac surgery were selected and randomly divided into non-invasive ventilation group and conventional treatment group (control group). The reintubation rate, tracheotomy rate, fatality rate, 24 h intake and output, respiratory rate, arterial blood gas PaO₂ and PaCO₂ were compared between the two groups of patients; at the same time, the patient comfort and mask leakage after improved nursing technology were compared. Results: The preoperative and intraoperative conditions of the two groups of patients were basically similar, but the reintubation rate, tracheotomy rate, fatality rate, and respiratory rate of the patients in the preventive application of NPPV group were significantly lower than those of the control group, and the 24 h input and output and arterial blood gas PaO₂ were also excellent in the control group. Conclusion: NPPV used prophylactically in high-risk patients after cardiac surgery can significantly reduce the re-intubation rate, improve patient outcomes, and is markedly more effective than the conventional treatment group.
