A portable computed tomography (CT) scan is used to manage and diagnose central nervous system diseases and acute brain injuries, in neuroscience intensive care units (NICU) , for example, traumatic brain injury (TBI), acute stroke, (transient ischemic attack) TIA and subarachnoid hemorrhage (SAH). CT studies are an important component in the evaluation and management of patients with brain injury. The portable device is specifically designed for head and neck scans of critically ill patients who are at risk of complications and increased morbidity during intra-hospital transport. Researchers have studied and found evidence showing that in-hospital transport of patients with SAH or brain injury can influence their outcomes. Many hospital protocols mandate the use of portable head CT (pHCT) scanners to monitor and evaluate critically ill NICU patients, to reduce the adverse effects of in-hospital transport on patient outcomes. This is an important factor in reducing and preventing secondary injuries in critically ill patients. The intent of this article is to conduct a critical analysis of a related research article. The article reviewed concerns portable head CT scanning and its effect on intracranial pressure (ICP), cerebral perfusion pressure (CPP), and cerebral oxygen. First, the premise of the study will be identified through a synopsis of the article. Second, the validity of the study will be described and discussed. Finally, this article will discuss how this research is applicable to the Neuro ICU at UNM Hospital. Article Synopsis: The authors of this research article were from the departments of Neurosurgery, Neurology, Anesthesia and Critical Care Medicine, Nursing, and Biostatistics and Epidemiology at the University of Pennsylvania...... half of the paper...... The research conducted by Peace et.al. raises a valid hypothesis that merits further study in order to reduce risks for patients in NICU and other units, in all hospitals. Studies with significant reliability data and high internal and external validity are critical to making changes in hospitals around the world to reduce secondary harm to patient populations and increase their chances of full recovery from injuries. Although this particular study produced preliminary data, similar protocols found in this study are implemented by the UNM NICU.Works CitedPeace, K., Maloney-Wilensky, E., Frangos, S., Hujcs, M., Levine, J., Kofke, W.
