Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We hypothesize that the stroke volume variation measured using the commercially available LiDCO monitor provides a reasonable estimate of volume when compared to standard measures. This study will collate data that is already being collected by the bedside nurses.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objective: To compare measurement of stroke volume variance with intake/output measurements, weight, BUN/Creatnine values, and central venous pressure.

Design: Non-experimental, non-randomized observational comparative study.

Setting: The sixteen bed Neurocritical Care Unit at Duke University Hospital.

Patients: 45 adult (over 18 years) subjects with intracranial pathology who require volume resuscitation. Only patients with current LiDCO monitoring will be considered eligible for inclusion in the study.

Interventions: This is an observational study. Subjects will receive standard-of-care treatment without additional intervention.

Data Analysis: All data will be collected by the principal investigator / study coordinator. Personal patient information will be removed (deidentified) from the permanent data collection records to protect patient confidentiality. Data collected will be entered into a Microsoft Excel electronic spreadsheet and will be saved on a USB Disk drive to be stored in a locked cabinet in the investigator's office. Statistical analysis using SAS v9.1, (Cary, NC) will be conducted with a level of significance set at .05 (alpha) using standardized comparative analysis techniques.
