Detection and Quantification of Neonatal Intraventricular Hemorrhage

Study Overview
=================
Brief Summary
-----------------
Dense array EEG and EIT (electrical impedence tomography) are new technologies that can add to information needed to diagnose neurological problems in infants - both preterm and term. The investigators propose a method to test these technologies in the preterm population to determine its safety and ease of use. The investigators will test on preterm infants of 30-34 weeks gestation, starting first with the older infants (32-34 weeks) then moving down to the smaller population (30-32 weeks). In both groups the investigators will start with a short time period and gradually extend the time as safety is established. All studies will be conducted at Shands Teaching Hospital at the University of Florida.

Detailed Description
-----------------
We propose to start with infants 32-34 weeks of gestation. Within this group, we will test the electrodes for increasing lengths of time. The first group will have the electrodes in place for 10 minutes. After doing this on two separate infants without issue, the length of time will increase to 1 hour, 4 hours, and end with 8 hours. To move up to the next time increment, safety will be documented in two infants. In all of the time groups tested we will enroll 2 infants, but with the final time group of 8 hours we will aim for 5 infants. Infants will be tested within the first 5 days of life. The neonate's gestational age will be recorded and the neonate assigned a study number. Information about the ease of use of the device, how it was fitted, and any effects it had on the skin. In addition, the head circumference, and the birth weight or weight at time of application will be collected. This will be the only medical information collected. After this group has been completed, we will enroll 30-32 week infants and follow the same protocol of time increments, with the same numbers needed to move up, and also with the goal of 5 infants in the final group of 8 hours. There will be a nursing evaluation form for the bedside nurse to complete accessing skin integrity and erythema after device removal, and also ease of use, and possible interference with cares and other devices. One clinical nurse will be the sole person placing and removing the net but the bedside nurse and will still do an evaluation evaluating the skin under and around the dense array every 30 minutes. The neonates head will be turned every 30 minutes following the skin check to avoid pressure injury related to the array. A brief optional questionnaire will be given to the bedside nurse to validate that the device did not interfere with the bedside nursing care (see questionnaire). Inclusion criteria will be infants 30-34 weeks gestation. Exclusion criteria will be any infants with evidence of pre-existing skin condition, breakdown, rashes, or problems with skin integrity. Infants with a known neurological condition (hydrocephalus, Dandy Walker malformation, craniosynostosis, AV malformation) will be excluded as well. Also, secondary to the nature of the device and the surface area it takes up, infants on CPAP will be excluded as well.

Eligibility Criteria
-----------------
Inclusion Criteria: Preterm infants 30-34 weeks gestation. Exclusion Criteria: Any infants with evidence of pre-existing skin condition, breakdown, rashes, or problems with skin integrity. Infants with a known neurological condition (hydrocephalus, Dandy Walker malformation, craniosynostosis, arteriovenous malformation) will be excluded as well. Also, secondary to the nature of the device and the surface area it takes up, infants on continuous positive airway pressure will be excluded as well.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety of Dense Array EEG monitoring systems in preterm infant population. | There will be a nursing evaluation form for the clinical nurse to complete accessing skin integrity and erythema after device removal, and also ease of use, and possible interference with cares and other devices. One clinical nurse will be the sole person placing and removing the net and evaluating the skin under and around the dense array every 30 minutes. The neonates head will be turned every 30 minutes following the skin check to avoid pressure injury related to the array per accepted preterm neonatal skin care protocols. | Few days after Dense Array EEG session. |
