ABSTRACT
INTRODUCTION: Recommendations regarding ventilation strategies in the setting of COVID-19, which may culminate in a clinical picture similar to ARDS, have not yet been well established. Prone positioning has shown benefit as an adjunct supportive measure for patients who develop ARDS. However, studies assessing the benefit of prone positioning have excluded patients with reduced intracranial compliance resulting in a unique predicament, whereby patients with concomitant neurological diagnoses and ARDS have no defined treatment algorithm or recommendations for management. METHODS: A systematic review of the literature, performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2009 guidelines, yielded 10 articles for analysis. Utilizing consensus from these articles, in combination with review of multi-institutional proning protocols for patients with non-neurologic conditions, a proning protocol for patients with intracranial pathology and concomitant ARDS was developed. RESULTS: Among the 10 studies included in final analysis, there was consensus that prone positioning should be considered when there is evidence of acute lung injury or ARDS in patients with neurologic injury. Patients may be proned with a speciality bed or manually on a standard bed with the assistance of seven to nine personnel, in the manner described herein. Special consideration for patients requiring frequent neurologic exams and patients at risk of cardiac arrest or seizure are discussed. CONCLUSION: While elevations in ICP and reductions in CPP do occur during proning, they may not occur to a degree that would warrant exclusion of prone ventilation as a treatment modality for patients with ARDS and concomitant neurological diagnoses. In cases where ICP, CPP, and PbtO2 can be monitored, prone-position ventilation should be considered a safe and viable therapy.
ABSTRACT
INTRODUCTION: The COVID-19 pandemic forced the implementation of social distancing guidelines to minimize spread of the coronavirus. However, it is not yet understood what effects these precautions had on the rates of penetrating neurotrauma. METHODS: We retrospectively analyzed neurotrauma data from our institutional trauma registry from distinct periods defined as pre-COVID-19 (March 2019-September 2019) and COVID-19 (March 2020-September 2020). Demographics, injury characteristics, mechanisms of trauma, and past medical history (including psychiatric diagnosis) were collected. Data were analyzed for between-group differences and presented as odds ratios. RESULTS: We observed a significant rise in the number of neurotrauma cases in 2020 (558 vs. 630, OR 1.129 [1.0071, 1.2657]). There was a decrease in the proportion of male victims (71.3% vs. 68.6%, p = 0.03). There were significant differences noted in the mechanism of injury between groups. Patients in 2020 were less likely to present with falls (42.3% vs. 34.3%, OR 0.7119 [0.5627, 0.9005]) and more likely to present with GSW (4.48% vs. 7.78%, OR 1.7981 [1.0951, 2.9523]). Of the patients with penetrating cranial injuries, the most common motive was assault (56.7% vs. 60.0%), followed by self-inflicted (13.3% vs. 20.0%) and accidental (20.0% vs. 18.3%) with a significant difference between years (p = 0.0043). The presence of comorbid psychiatric illness or substance abuse did not confer an increased odds of presenting with penetrating injuries. No significant differences were noted in mean arrival or discharge GCS or injury severity as measured by ISS. However we did observe significant increases in patients presenting with bilaterally reactive pupils (48.3% vs 59.3%, p = 0.0025), patients discharged home (27.6% vs 37.3%, p = 0.0002), and survival at 6 months (41.4% vs. 54.2%, p = 0.0188). CONCLUSION: We observed a higher rate of penetrating neurotrauma while social distancing measures were in place. It is unclear if the psychosocial effects of quarantine and social distancing had a causative relationship with the increased rates of assault and self-inflicted penetrating injuries.
