The brain-lung interaction can seriously affect patients with traumatic brain injury, triggering a vicious cycle that worsens patient prognosis. Although the mechanisms of the interaction are not fully elucidated, several hypotheses, notably the “blast injury” theory or “double hit” model, have been proposed and constitute the basis of its development and progression. The brain and lungs strongly interact via complex pathways from the brain to the lungs but also from the lungs to the brain. The main pulmonary disorders that occur after brain injuries are neurogenic pulmonary edema, acute respiratory distress syndrome, and ventilator-associated pneumonia, and the principal brain disorders after lung injuries include brain hypoxia and intracranial hypertension. All of these conditions are key considerations for management therapies after traumatic brain injury and need exceptional case-by-case monitoring to avoid neurological or pulmonary complications. This review aims to describe the history, pathophysiology, risk factors, characteristics, and complications of brain-lung and lung-brain interactions and the impact of different old and recent modalities of treatment in the context of traumatic brain injury.

Background
Decreases in heart rate variability have been shown to be associated with poor outcomes in severe acute brain injury. However, it is unknown whether the changes in heart rate variability precede neurological deterioration in such patients. We explored the changes in heart rate variability measured by electrocardiography in patients who had neurological deterioration following severe acute brain injury, and examined the relationship between heart rate variability and electroencephalography parameters.
Methods
Retrospective analysis of 25 patients who manifested neurological deterioration after severe acute brain injury and underwent simultaneous electroencephalography plus electrocardiography monitoring.
Results
Eighteen electroencephalography channels and one simultaneously recorded electrocardiography channel were segmented into epochs of 120-second duration and processed to compute 10 heart rate variability parameters and three quantitative electroencephalography parameters. Raw electroencephalography of the epochs was also assessed by standardized visual interpretation and categorized based on their background abnormalities and ictalinterictal continuum patterns. The heart rate variability and electroencephalography parameters showed consistent changes in the 2-day period before neurological deterioration commenced. Remarkably, the suppression ratio and background abnormality of the electroencephalography parameters had significant reverse correlations with all heart rate variability parameters.
Conclusions
We observed a significantly progressive decline in heart rate variability from the day before the neurological deterioration events in patients with severe acute brain injury were first observed.

Abstract PDF: The fact that therapeutic hypothermia (TH) has lowered intracranial pressure and protected brain in severe traumatic brain injury (TBI) is well known throughout past sources and experimental data. In this paper, the result of TH in TBI needs to be confirmed. The result of North American Brain Injury Study; Hypothermia (NAVIS-H) 1 and 2, Eurotherm3235, Japan trauma society study was reviewed throughout randomized controlled study which performed recently. The prognosis was not confirmed throughout TH in NAVIS-H1; however, there was statistical significance among the group of 45 years or less and below 35 degree in celcius which checked when he or she visited initially. Hence, NAVIS-H2 study was preceded. In patient who had surgically removed hematoma, the effects of TH were proved compared to diffuse brain damage in NAVIS-H2 study. This was found in the result of Japan neurotrauma data bank. Eurotherm study has been doing, which leads to collect many data later on. The TBI of TH makes them better prognosis in patients who had surgically removed hematoma and lowered initial body temperature. Later on, it is considered further study is necessary.
