Alveolar-arterial partial pressure difference as an early predictor for patients with acute paraquat poisoning.

ABSTRACT:

Objective

Paraquat (PQ) is associated with high mortality rates in acute poisoning. This study aimed to determine the importance of the alveolar-arterial partial pressure difference (A-aDo₂) in the expected consequences of acute PQ poisoning.

Methods

Patients who were hospitalized for PQ poisoning in 2018 were enrolled in this retrospective study. A-aDo₂ data were collected. Multivariate analysis was performed using binary logistic regression to determine whether A-aDo₂ is an independent risk factor for mortality from PQ.

Results

A total of 352 cases were analyzed. The mean PQ dose was 36.84 ± 50.30 mL (0.3-500 mL). There were 185 survivors and 167 non-survivors. The mean A-aDo₂ was not significantly correlated between survi
