Effects of prone position combined with reverse Trendelenburg position on oxygenation among acute respiratory distress syndrome patients

Abstract

Objective To explore the effects of prone position combined with reverse Trendelenburg position on improving hypoxemia and respiratory mechanics of acute respiratory distress syndrome (ARDS) patients. Methods From January 2017 to December 2017, we selected ARDS inpatients in Intensive Care Unit at Affiliated Hospital of Shaoxing University as subjects by convenience sampling. The total of 20 patients were divided into group A and group B with the method of random number table. Patients of group A adopted prone position for two hours firstly, and then they adopted prone position combined with reverse Trendelenburg position for six hours. Patients of group B adopted prone position combined with reverse Trendelenburg position for two hours firstly, and then they adopted prone position for six hours. During treatment, we assessed the function of pulmonary ventilation and respiratory mechanics of patients. Results There were statistical differences in different time, different groups and interaction between time and groups among ARDS patients between two groups (P 0.05) . One, five and eight hours after intervention, the oxygenation indexes of group A were higher than those of group B with statistical differences (P 0.05) . Conclusions Prone position combined with reverse Trendelenburg position can improve the oxygenation of ARDS patients.
