Title: Neurological Severity Classification System (CSN-System) in adults with BTI, Hospital Cayetano Heredia, Lima - Peru, 2020. Preliminary study.


Brain trauma injury (BTI) is the disruption function and architecture of brain. The Glasgow Coma Scale (GCS) is the most widely used TBI severity classification; however, it has some limitations. The Neurological Severity Classification System (CSN System), a clinical-tomographic instrument designed to overcome lesion heterogeneity, assesses brain function and structure in determining the severity of BTI. Observational, prospective and cross-sectional study in adults with BTI from Cayetano Heredia Hospital, 2020. The CSN System was compared with the GCS in the BTI classification.
Of 29 patients, 82.76% were male and 82.76% were between 18 and 64 years old. The severity of the BTI through the CSN System: very mild 6.70%, mild 17.24%, moderate 51.72%, severe 17.24% and critical 6.70%.

There was an association between the CSN System and the indication for neurosurgical intervention (p = 0.002) and high sensitivity-specificity in the distinction of severity categories with the CSN System; there was lower GCS performance.

The CSN System, clinical-tomographic, improves the determination of severity of the BTI compared to the GCS and provides an excellent relationship with the indication for neurosurgical intervention.


Elder Castro has completed his studies from Universidad Peruana Cayetano Heredia. A part of his training was carried out in Argentina. He has made publications since his training period in the medical residency. He currently performs his work as a neurosurgeon at the Cayetano Heredia Hospital (Peru) in patients with traumatic brain, traumatic vertebromedullary and aneurysmal pathology.
