Traumatic brain injury (TBI) is a serious health issue in the United States, killing 100,000 people a year and serving as a source of long-term disability for many more. It is the leading cause of death in patients under the age of 45 years. ⋯ Key skills in the care of brain-injured patients include adequately gauging the severity of injury, recognizing the primacy of sufficient blood flow and oxygen delivery to the injured brain, and being able to detect and correct when possible local and global physiological abnormalities that frequently put the injured brain at ongoing risk within the intensive care unit. This article discusses these issues, including invasive hemodynamic and intracranial monitoring, useful methods for reducing intracranial pressure, and management of complications arising from acute head injury.

Lateral canthotomy and cantholysis is a simple procedure that can be performed by emergency physicians. It has the potential to save vision, particularly in cases of blunt ocular trauma. The case of a 37-year-old man with blunt ocular trauma, a retrobulbar hemorrhage and rapidly increasing orbital pressure requiring an urgent lateral canthotomy and cantholysis is presented. Pathophysiology, indications, contraindications, procedure and follow-up care are described.

Cerebrospinal fluid procalcitonin and severe traumatic brain injury in children.
To determine the relationship between cerebrospinal fluid procalcitonin concentration and severe traumatic brain injury in children. ⋯ Cerebrospinal fluid procalcitonin concentration is increased in children after traumatic brain injury. The attenuated increase in cerebrospinal fluid procalcitonin among victims of abusive head trauma warrants further study because it may reflect impairment of endogenous neuroprotective mechanisms or delay in seeking medical attention. The significance of these observations remains to be determined as future studies elucidate the physiologic and mechanistic properties of procalcitonin.

Measuring outcome in pediatric intensive care is necessary to equate the high cost of treatment with benefits to the patient. Although mortality rates and morbidity are relatively insensitive measures of the benefits of treatment, quality of life measurement gives insight into the long-term outcomes. The aim of this study was to investigate the long-term quality of life outcome of children admitted to a pediatric intensive care unit. ⋯ Our results indicate that the long-term outcome in terms of quality of life after admission to a pediatric intensive care unit is good or normal for the majority of surviving children. Those children with a poor outcome are likely to have significant comorbidities or a diagnosis of malignancy.

An investigation was made of the population and function of lymphocytes in canine peripheral blood, in animals with or without laparotomy under inhalation anesthesia. ⋯ These results indicate that surgical trauma concomitant with anesthesia could impair immunocompetence by reducing the number and function of lymphocytes.
