Insights
Early awake proning in the emergency department significantly improved oxygen saturation in COVID-19 patients. This intervention showed promise for managing hypoxia in non-intubated patients.
Area of Science:
- Emergency Medicine
- Critical Care Medicine
- Pulmonology
Background:
- Hypoxia in COVID-19 patients can lead to poor outcomes.
- Proning is a recognized intervention for Acute Respiratory Distress Syndrome (ARDS).
- Early intervention is crucial for managing hypoxemia.
Purpose of the Study:
- To describe the use of early proning in awake, non-intubated COVID-19 patients in the ED.
- To assess the impact of proning on oxygen saturation.
- To evaluate intubation failure rates within 24 hours.
Main Methods:
- Pilot study in a single urban Emergency Department (ED).
- Included patients with suspected COVID-19 and hypoxia.
- Measured SpO2 before and after 5 minutes of proning with supplemental oxygen.
Main Results:
- Median SpO2 improved from 80% at triage to 94% after proning (P=0.001).
- Supplemental oxygen alone increased SpO2 to 84%.
- 24% of patients required intubation within 24 hours.
Conclusions:
- Early self-proning in the ED improved oxygen saturation in COVID-19 patients.
- This intervention shows potential for managing hypoxemia in awake patients.
- Further research is needed to confirm causality and impact on mortality.
Objective:
Prolonged and unaddressed hypoxia can lead to poor patient outcomes. Proning has become a standard treatment in the management of patients with ARDS who have difficulty achieving adequate oxygen saturation. The purpose of this study was to describe the use of early proning of awake, non-intubated patients in the emergency department (ED) during the COVID-19 pandemic.
Methods:
This pilot study was carried out in a single urban ED in New York City. We included patients suspected of having COVID-19 with hypoxia on arrival. A standard pulse oximeter was used to measure SpO2 . SpO2 measurements were recorded at triage and after 5 minutes of proning. Supplemental oxygenation methods included non-rebreather mask (NRB) and nasal cannula. We also characterized post-proning failure rates of intubation within the first 24 hours of arrival to the ED.
Results:
Fifty patients were included. Overall, the median SpO2 at triage was 80% (IQR 69 to 85). After application of supplemental oxygen was given to patients on room air it was 84% (IQR 75 to 90). After 5 minutes of proning was added SpO2 improved to 94% (IQR 90 to 95). Comparison of the pre- to post-median by the Wilcoxon Rank-sum test yielded P = 0.001. Thirteen patients (24%) failed to improve or maintain their oxygen saturations and required endotracheal intubation within 24 hours of arrival to the ED.
Conclusion:
Awake early self-proning in the emergency department demonstrated improved oxygen saturation in our COVID-19 positive patients. Further studies are needed to support causality and determine the effect of proning on disease severity and mortality.
