Summary of "Pupillometry Trends in the Setting of Increased Intracranial Pressure."

Serial pupil examinations remain a mainstay of neurological assessments performed by neuroscience nurses. Integration of pupillometer technology has increased in recent years, because of its ability to address limitations of manual examinations and to evaluate trended data over time. Preliminary research has linked pupillometer values to intracranial pressure (ICP) values, but data on pupillary changes in the setting of increased ICP remain sparse. The purpose of this study was to determine trends in pupillometer values in the setting of increased ICP among critically ill patients with neurological injury. This is a secondary analysis of data where serial pupillometer and ICP readings were recorded hourly on adult patients with neurological injury necessitating critical care management. More than 2100 paired serial pupillometer and ICP readings were obtained from 76 subjects, with a total of 2107 paired readings for the left eye and 2175 for the right eye. There were statistically significant differences in pupillometry values in the setting of increased ICP. Time series analysis indicates that spikes in ICP values resulted in corresponding variations in pupillometer values. Use of automated pupillometry remains a value adjunct to traditional invasive therapies. Evaluation of trended data may provide insight into ICP elevations in the absence of invasive monitoring and warrants additional research.

Medical and Biotech [MESH] Definitions

Manometric pressure of the CEREBROSPINAL FLUID as measured by lumbar, cerebroventricular, or cisternal puncture. Within the cranial cavity it is called INTRACRANIAL PRESSURE.

Pressure within the cranial cavity. It is influenced by brain mass, the circulatory system, CSF dynamics, and skull rigidity.

Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.

A method of examining and setting levels of payments.

The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
