Construction and application of prone position ventilation management scheme for severe COVID-19 patients

Background: Prone position ventilation (PPV) can significantly improve oxygenation index and blood oxygen saturation in most (70%-80%) patients with acute respiratory distress syndrome. However, although PPV is not an invasive procedure, there are many potential PPV-related complications, such as nerve compression, crush injury, venous stasis (e.g., facial oedema), pressure sores, retinal damage, vomiting, and arrhythmia, with an incidence of up to 56.9%. Nursing managers have focused on reducing the occurrence of PPV-related complications and improving safety. Objective: To construct a prone ventilation management scheme for patients with severe coronavirus disease 2019 (COVID-19) and analyse its application effect. Methods: Based on a previous evidence-based study combined with the COVID-19 Diagnosis and Treatment Protocol (Trial Edition 9), a prone ventilation management protocol for severe COVID-19 was formulated and applied to COVID-19 patients in the intensive care unit of a designated hospital. A prospective self-control study was used to compare changes in the oxygenation index and other outcome indicators before and after the intervention. Results: The oxygenation index of patients after intervention (321.22 +/- 19.77mmHg) was significantly higher (p < 0.05) than before intervention (151.59 +/- 35.49 mmHg). The difference in oxygenation index in different prone position ventilation durations was statistically significant (p < 0.05). Nursing quality evaluation indicators showed that the implementation rate of gastric residual volume assessment was 100% and the incidence of occupational exposure and cross-infection was 0%; the incidences of pressure ulcers, drug extravasation, and facial oedema were 13.64% (3/22), 4.54% (1/ 22), and 4.54% (1/22), respectively. The incidence of unplanned extubation, aspiration, and falls/falls was 0%.
