incidence and outcomes of acute lung injury in patients with isolated traumatic brain injury

Background and aim: traumatic brain injury (tbi) is an essential cause of morbidity andmortality worldwide. tbi patients frequently encounter lung complications, such as acutelung injury (ali) and acute respiratory distress syndrome (ards), which is associated withpoor clinical outcome because hypoxia causes additional injury to the brain. this study aimedto evaluate the frequency of ali in patients with tbi and its consequences.methods and materials/patients: in this descriptive cross-sectional study, data from allrecords of patients admitted to poursina hospital’s icu (emergency and neurosurgery icu)in 20 18-2019 were used. the evaluated data included age, gender, type of head traumamechanism, kind of brain injury based on ct scan findings, the severity of brain injury basedon glasgow coma scale (gcs), underlying diseases, mean head ais score, the number of packcell units injected, as well as bilateral pulmonary infiltration in favor of ali and brain injury.results: only 81 of the 557 tbi cases met the inclusion criteria of the present study. thehighest frequency of ali following tbi was observed on the first day of hospitalization,in men (0.41%) in the age group of 40-50 years (7%) with severe brain damage (6%) andsubdural hematoma (12%), following a motorcycle accident, cars, as well as on the third dayof hospitalization were seen in men (43.8%) with the age group of 20-30 years (55%) withsevere brain damage (42%) and intra-parenchymal bleeding (57%), following a motorcycleaccident. in addition, no significant correlation was detected between the incidence of aliand mortality, the duration of hospitalization, gcs, mean head ais score, or the extent ofreceived blood units in our study.conclusion: according to the obtained findings, men aged between 20 and 30 years withsevere cerebral injury, epidural hematoma and a motorcycle accident presented the highestrate of progression toward ali in the first to third days of hospitalization.
