Post-intubation hypotension (PIH) was one of the serious complications after Endotracheal intubation (ETI) in Severe pneumonia (SP) patients. The risk factors of PIH were investigated in SP patients to provide a theoretical basis of early intervention.

This was a retrospective study wherein 420 SP patients undergone ETI from December 2019 to December 2022 were selected as the study subjects. Patients were divided into the hypotension and normal blood pressure groups based on the blood pressures recorded after intubation.

Two groups were compared for the general data and various physicochemical indicators before the intubation.

The independent risk factors of hypotension after tracheal intubation were explored in SP patients through univariate and multivariate logistic regression
