Comparison of the Effects of Mechanical Ventilation in Prone and Supine Positions on Blood Gas Analysis Indicators and Hemodynamics Indicators in Patients with Moderate to Severe ARDS
Objective To investigate the effects of mechanical ventilation in prone and supine positions on blood gas analysis indicators and hemodynamics indicators in patients with moderate to severe acute respiratory distress syndrome(ARDS).Methods A total of 62 patients with moderate to severe ARDS admitted to Linyi Central Hospital from January 2022 to December 2023 were selected as the research subjects,according to the random number table method,they were divided into a supine group and a prone group,with 31 cases in each group.The supine group received conventional semi recumbent mechanical ventilation treatment,while the prone group received prone mechanical ventilation treatment.Compare the blood gas analysis indicators,hemodynamic indicators and occurrence of complications between the two groups.Results After 3 days of treatment,the levels of oxygenation index,partial pressure of oxygen in both groups was higher than before treatment,and the prone group were higher than those in the supine group,the levels of partial pressure of carbon dioxide in both groups were lower than before treatment,and the prone group was lower than those in the supine group,the differences were statistically significant(P<0.05);there was no statistically significant difference in heart rate between the two groups(P＞0.05);the levels of central venous pressure and mean arterial pressure in both groups were higher than before treatment,and the prone group were higher than the supine group,the differences were statistically significant(P<0.05).Comparison of incidence of complications between two groups,the difference was not statistically significant(P＞0.05).Conclusion Patients with moderate to severe ARDS treated with prone mechanical ventilation showed better improvement in blood gas analysis indicators and hemodynamic indicators compared to supine mechanical ventilation,and had good safety.
