Is endotracheal intubation a non-beneficial treatment in patients with respiratory failure due to paraquat poisoning?

Introduction: Paraquat poisoning can result in dysfunction of multiple organs, and pulmonary fibrosis with respiratory failure is the major cause of mortality. For terminally ill patients, some life-prolonging treatments can be non-beneficial treatments (NBT). The objective of this study was to determine if intubation is a NBT for patients with respiratory failure due to paraquat poisoning.
