Abstract

Objectives: To examine the effectiveness of prone positioning on COVID-19 patients with acute respiratory distress syndrome with moderating factors in both traditional prone positioning (invasive mechanical ventilation) and awake self-prone positioning patients (non-invasive ventilation).

Research methodology: A comprehensive search was conducted in CINAHL, Cochrane library, Embase, Medline-OVID, NCBI SARS-CoV-2 Resources, ProQuest, Scopus, and Web of Science without language restrictions. All studies with prospective and experimental designs evaluating the effect of prone position patients with COVID-19 related to acute respiratory distress syndrome were included. Pooled standardised mean differences were calculated after prone position for primary (PaO2/FiO2) and secondary outcomes (SpO2 and PaO2) RESULTS: A total of 15 articles were eligible and included in the final analysis. Prone position had a statistically significant effect in improving PaO2/FiO2 with standardised mean difference of 1.10 (95%CI 0.60-1.59), SpO2 with standardised mean difference of 3.39 (95% CI 1.30-5.48), and PaO2 with standardised mean difference of 0.77 (95% CI 0.19-1.35). Patients with higher body mass index and longer duration/day are associated with larger standardised mean difference effect sizes for prone positioning.

Conclusions: Our findings demonstrate that prone position significantly improved oxygen saturation in COVID-19 patients with acute respiratory distress syndrome in both traditional prone positioning and awake self-prone positioning patients. Prone position should be recommended for patients with higher body mass index and longer durations to obtain the maximum effect.
