Randomized Controlled TrialUse of olanzapine to treat agitation in traumatic brain injury: a series of n-of-one trials.
Agitation is common during post-traumatic amnesia (PTA) following traumatic brain injury (TBI) and is associated with risk of harm to patients and caregivers. Antipsychotics are frequently used to manage agitation in early TBI recovery despite limited evidence to support their efficacy, safety, and impact upon patient outcomes. The sedating and cognitive side effects of these agents are theorized to exacerbate confusion during PTA, leading to prolonged PTA duration and increased agitation. ⋯ Importantly, administration of olanzapine during PTA may lead to increased patient confusion, possibly prolonging PTA. When utilizing olanzapine, physicians must therefore balance the possible advantages of agitation management with the possibility that the patient may never respond to the medication and may experience increased confusion, longer PTA and potentially poorer outcomes. Further high-quality research is required to support these findings and the efficacy and outcomes associated with the use of any pharmacological agent for the management of agitation during the PTA period.

Randomized Controlled TrialKetofol as an Anesthetic Agent in Patients With Isolated Moderate to Severe Traumatic Brain Injury: A Prospective, Randomized Double-blind Controlled Trial.
The effects of ketofol (propofol and ketamine admixture) on systemic hemodynamics and outcomes in patients undergoing emergency decompressive craniectomy for traumatic brain injury (TBI) are unknown and explored in this study. ⋯ Compared with propofol, ketofol for induction and maintenance of anesthesia during decompressive surgery in patients with moderate/severe TBI was associated with improved hemodynamic stability, lower vasopressor requirement, and similar brain relaxation.

Machine Learning-Based Prognostic Model for the Prediction of Early Death after Traumatic Brain Injury: Comparison with the Corticosteroid Randomization after Significant Head Injury (CRASH) Model.
Machine learning (ML) has been used to predict the outcomes of traumatic brain injury. However, few studies have reported the use of ML models to predict early death. This study aimed to develop ML models for early death prediction and to compare performance with the corticosteroid randomization after significant head injury (CRASH) model. ⋯ The ML models may have comparable performances compared to the CRASH model despite being developed with a smaller sample size.

Randomized Controlled TrialBalanced crystalloid vs saline in adults with traumatic brain injury: secondary analysis of a clinical trial.
Balanced crystalloids may improve outcomes compared with saline for some critically ill adults. Lower tonicity of balanced crystalloids could worsen cerebral edema in patients with intracranial pathology. The effect of balanced crystalloids versus saline on clinical outcomes in patients with traumatic brain injury (TBI) requires further study. ⋯ Patients in the balanced crystalloid group were more likely to die or be discharged to another medical facility (aOR 1.38 [1.02-1.86]; p = 0.04). Overall, balanced crystalloids were associated with worse discharge disposition in critically injured patients with TBI compared with saline. The confidence intervals cannot exclude a clinically relevant increase in mortality when balanced crystalloids are used for patients with TBI.

Randomized Controlled TrialPlasma Neurofilament Light and Glial Fibrillary Acidic Protein Levels over Thirty Days in a Porcine Model of Traumatic Brain Injury.
To establish the clinical relevance of porcine model of traumatic brain injury (TBI) using the plasma biomarkers of injury with diffusion tensor imaging (DTI) over 30 days, we performed a randomized, blinded, pre-clinical trial using Yorkshire pigs weighing 7-10 kg. Twelve pigs were subjected to Sham injury (n = 5) by skin incision or TBI (n = 7) by controlled cortical impact. Blood samples were collected before the injury, then at approximately 5-day intervals until 30 days. ⋯ Porcine model of TBI replicates the acute increase in plasma biomarkers seen in clinical TBI. Further, long term white matter injury is confirmed in the areas such as the splenium and corona radiata. However, future study stratifying severe and mild TBI, as well as comparison with other subtypes of TBI such as diffuse axonal injury, may be warranted.
