Abstract

Transport of premature infants incurs transfer-related morbidity, including intraventricular hemorrhage, a contributing factor to cerebral palsy. The force transmitted to the neonate during transport as a consequence of motion may be implicated in the increased morbidity in this population. Morbidity may occur via direct concussive force to a vulnerable germinal matrix, induction of an inflammatory reaction, or via transient desaturation via extubation. This transmitted force, measured as accelerations per unit time (impulse), is not well characterized. Any modification of a neonatal transporter which increases the time for a neonate in motion to come to rest may decrease the impulse experienced by the infant. The objective of the study was to quantify the magnitude of impulse experienced by neonates during inter- and intra-hospital transport using a novel biophysical model and determine whether a specialized air-foam mattress can reduce the transmitted impulse on the neonate. Five roundtrip trials were conducted for a transported neonate using a standard medical ambulance and transport isolette outfitted with an air-foam mattress. During the trials, measurements were made per second in the X (front-to-back), Y (side-to-side), ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
