The influence of the COVID-19 pandemic on traumatic brain injuries in Tyrol: experiences from a state under lockdown.

ABSTRACT: PURPOSE:In February 2020, the federal state of Tyrol in Austria has become one of the epicenters of the COVID-19 pandemic. Tyrol is known for numerous skiing areas. Thus, winter sport resorts became a starting point for COVID-19 infections spreading towards the rest of the state, Austria and other countries, leading to a mandatory quarantine for almost a million people, who were placed under a curfew and restrictions in daily life. Additionally, all ski resorts and hotels were closed. We aimed to analyze the influence of the COVID-19 quarantine on traumatic brain injury (TBI) cases in Tyrol. METHODS:We retrospectively compared demographical and injury characteristics from all TBI patients within the 2020 strict quarantine period with the respective time periods from 2016 to 2019. As our department is the only neurosurgical unit in Tyrol, all patients with moderate or severe TBI are transferred to our hospital. RESULTS:During 3 weeks of the full quarantine period, the weekly TBI cases load decreased significantly in comparison to the same time periods in the years 2016-2019. Furthermore, concomitant skull fractures decreased significantly (p?

Project description:Severe impacts to the head commonly lead to localized brain damage. Such impacts may also give rise to temporary pressure changes that produce secondary injuries in brain volumes distal to the impact site. Monitoring pressure changes in a clinical setting is difficult; detailed studies into the effect of pressure changes in the brain call for the development and use of animal models. The aim of this study is to characterize the pressure distribution in an animal model of penetrating traumatic brain injuries (pTBI). This data may be used to validate mathematical models of the animal model and to facilitate correlation studies between pressure changes and pathology. Pressure changes were measured in rat brains while subjected to pTBI for a variety of different probe velocities and shapes; pointy, blunt, and flat. Experiments on ballistic gel samples were carried out to study the formation of any temporary cavities. In addition, pressure recordings from the gel experiments were compared to values recorded in the animal experiments. The pTBI generated short lasting pressure changes in the brain tissue; the pressure in the contralateral ventricle (CLV) increased to 8 bar followed by a drop to 0.4 bar when applying flat probes. The pressure changes in the periphery of the probe, in the Cisterna Magna, and the spinal canal, were significantly less than those recorded in the CLV or the vicinity of the skull base. High-speed videos of the gel samples revealed the formation of spherically shaped cavities when flat and spherical probes were applied. Pressure changes in the gel were similar to those recorded in the animals, although amplitudes were lower in the gel samples. We concluded cavity expansion rate rather than cavity size correlated with pressure changes in the gel or brain secondary to probe impact. The new data can serve as validation data for finite element models of the trauma model and the animal and to correlate physical measurements with secondary injuries.
