ReviewDelirium phenomenology illuminates pathophysiology, management, and course.
The phenomenology of delirium has received little standardized longitudinal study but offers the prospect of valuable insights regarding clinical subtypes, differentiation from other neuropsychiatric disorders, identification of underlying pathophysiologies, management, and course. This review examines current approaches to the investigation of delirium phenomenology and how the findings to date illuminate our understanding of delirium. It concludes with recommendations for future investigations.

Randomized Controlled Trial Clinical TrialTreatment of elevated intracranial pressure by infusions of 10% saline in severely head injured patients.
The management of intracranial pressure (ICP) is a factor in outcome of patients with head trauma. However, recent studies have revealed that the current strategies, which have been applied to control ICP for adequate cerebral perfusion, are unsatisfactory. Against this background, the efficacy of short-term infusions of hypertonic saline on ICP was investigated. ⋯ In the individual cases the temporal course of the parameters amplitude and decline interval depict a tendency toward lower and higher values, respectively, under conditions of a generally increasing ICP. As expected, the infusion of hypertonic saline reduces ICP in patients suffering from SHI. The pressure drop, duration and dynamic behaviour are suspected to depend both on the pressure level to reduce and concomitant medications.

Although more common in collision sports, head injuries (for this article confined to cerebral neurotrauma) may occur in virtually any form of athletics. A few such injuries result in death, especially the second-impact syndrome and subdural hematoma. ⋯ These misunderstandings in the field have contributed to a paucity of reliable epidemiological information about its actual frequency. The concerns accompanying cerebral insult are discussed more than studied, but much can be gained in principle from the history of attention to concussions in football.

Severe head injury with and without peripheral trauma is the most frequent cause of death and of severe disability up to 45 years. Outcome is determined by two major factors, the extent and nature of the irreversible primary brain damage, and the evolving secondary sequelae, which contrary to the former are responsive in principle to therapeutic intervention. An improvement of outcome from severe head injury can be expected only from an increased efficiency of the measures to prevent secondary brain damage. ⋯ Current results and experiences with establishment of this comprehensive research organization are presented, where no less than 31 hospitals. Institutions and organizations, and a study group of more than 40 physicians, students and statisticians are collaborating. Emerging data appear to be suitable to further improve pertinent aspects of the patient management as a basis to lower the incidence of secondary brain damage from severe head injury.

Complications and safety associated with ICP monitoring: a study of 542 patients.
In our institution ICP was monitored in patients with GCS < or = 8 and abnormal CT scan: 362 severely head injured and 180 subarachnoid hemorrhage. Mean duration of monitoring was 103.6 hours (SD 74.96). Among 542 patients, 440 showed at least one episode of ICP above the threshold of 20 mm Hg. ⋯ In 13 cases (2.2%) a ventricular infection has been diagnosed. In 1 case an intraparenchimal hemorrhage related to the presence of the catheter was detected. Elevated risk of HICP and low incidence of complications have been shown in this series.
