Brain Trauma Foundation Guidelines for the Management of Penetrating Traumatic Brain Injury, Second Edition.
Guideline
Overview
abstract
BACKGROUND: Penetrating traumatic brain injury (pTBI) affects civilian and military populations resulting in significant morbidity, mortality, and health care costs. No up-to-date and evidence-based guidelines exist to assist modern medical and surgical management of these complex injuries. METHODS: A preliminary literature search informed a need for updated guidelines. Methodologists experienced in TBI guidelines supported 2 co-chairs, a diverse steering committee and three expert working groups. Over half of our panelists were active service military or military veterans and they addressed twenty-six Key Questions (KQs). We searched Ovid MEDLINE®, EMBASE, and Cochrane CENTRAL from inception to August 31, 2022, reference lists, and clinical trial registries. Penetrating, perforating and tangential penetrating brain injuries were included. Predefined criteria were used to identify studies; pre-specified methods were used to assess study quality and strength of evidence for key outcomes. Effects were analyzed qualitatively and quantitatively where appropriate. RESULTS: 125 studies provided evidence and another 80 studies provided contextual data for these guidelines. In general there was a paucity of literature and most of the identified evidence was judged to be high risk of bias due to study design. We did not identify any studies meeting inclusion criteria for 12 KQs. The highest quality evidence, rated moderate in strength, was identified for four KQs that covered: cerebral angiography vs computed tomography angiography, the relationship between bihemispheric injury in adult pTBI and mortality, the ability of the Surviving Penetrating Injury to the Brain (SPIN) score to predict mortality, and the relationship between infection and cerebrospinal fluid fistula. Evidence for most KQs came from case series. CONCLUSIONS: The development of up-to-date evidence and consensus based clinical care guidelines and algorithms for pTBI provide guidance to care providers in the prehospital and emergency medicine, surgical and intensive care settings. Few moderately strong conclusions on the benefit of specific management strategies for penetrating brain injury could be made. Detailed reporting of patient outcomes in future studies could advance the field by providing greater evidence for specific treatments by patient population, mechanism of injury, severity of injury, and specific interventions employed.
