Evaluation of oxygen saturation as an indicator for tracheal intubation in patients with COVID-19: a prospective cohort study

Messenger of Anesthesiology and Resuscitation (2023)

Background. Since the beginning of COVID-19 pandemic, the importance of clinical criteria for tracheal intubation in critically ill patients with respiratory failure became more noteworthy, especially in resource limitations. The objective was to evaluate the importance of hemoglobin oxygen saturation as a criterion for tracheal intubation in patients with COVID-19. Materials and methods. This is a multi-center, prospective, observational cohort study. We included 117 patients with COVID-19 who needed respiratory support between March to June 2021. Patients were intubated by the protocol of each institution participating in the study and the anesthesiologist’s clinical judgement. Signs of respiratory failure, methods of respiratory support and patient outcome were recorded. Results. Among 117 studied cases, 100 patients had hemoglobin oxygen saturation of 60–90 % in whom 58 were intubated. During hospitalization, 56 intubated patients and 14 non-intubated patients died (96.6 % Vs. 33.3 %). Conclusion. Arterial blood hemoglobin oxygen saturation of 60–90 could not be the correct key to unlock the problem of intubation decision in patients with COVID-19. Therefore, hemoglobin oxygen saturation should not be solely regarded as an indication for intubation in COVID-19.

Abstract Background: Since the beginning of COVID-19 pandemic, lack of clinical criteria for intubation in critically ill patients with respiratory failure and simultaneous resource limitations became more noteworthy than before. This study is designed in order to investigate oxygen saturation as an indicator for tracheal intubation in COVID-19 patients. Methods: This is a multi-center, prospective, observational cohort study. We included patients with COVID-19 who needed respiratory support between March to June 2021. Patients were intubated by each institute’s protocol and the anesthesiologist’s clinical judgement. Respiratory symptoms, methods of respiratory support and patients’ outcome were recorded. Results: In this study 117 patients were enrolled. Among 117 studied cases, 100 patients had O2 saturation of 60-90% in whom 58 were intubated. During hospitalization, 56 intubated patients and 14 non-intubated patients died (96.6% Vs. 33.3%). Conclusion: We found that oxygen saturation per se cannot be appropriate criteria for intubating decision.
