Trial Outcomes & Findings for Measures to Lower the Stress Response in Pediatric Cardiac Surgery (NCT NCT00848393)

A total of 51 study subjects completed the study.

Total number of subjects recruited was 52 patients (one enrollee withdrew prior to any study-related procedures) resulting in a total number of subjects participating of 51. The enrollee was withdrawn from the study after signing the consent and prior to enrolling to one of the arms of the study.

Measures to Lower the Stress Response in Pediatric Cardiac Surgery

N = 48 n = 16 (LDF); n = 17 (HDF); n = 15 (LDF + Dex) ACTH assayed by enzyme-linked immunosorbent assay (ELISA); Cytokine levels in plasma were measured using the Immulite automated chemiluminometer. Measured cytokines include interleukin (IL)-6, IL-8, IL-10, and tumor necrosis factor-α.

The Stanford-Binet test evaluates the overall IQ score from the assessment of cognitive ability. The test consists of 15 subtests, grouped into the four area scores. Six subtests are administered to all age levels. The subtests are: Vocabulary, Comprehension, Pattern Analysis, Quantitative, Bead Memory, and Memory for Sentences. Number of tests administered and test difficulty are based on the test taker's age and performance on subtest measuring word knowledge. The word knowledge subtest is given to all test takers and is the first subtest administered. A score of 100 is in the normal or average range. Higher scores suggest a higher level of functioning related to each category. (University of Cincinnati, 2003) Raw scores for each subtest within the overall test are converted to scaled scores using a table within each test manual to look up equivalents. Scaled scores are then converted to standard scores (range=50-150).

Cortisol, epinephrine, and norepinephrine assayed by enzyme-linked immunosorbent assay (ELISA).

The Stanford-Binet Intelligence Scale is now in its fifth edition (SB5) and was released in 2003. It is a cognitive ability and intelligence test that is used to diagnose developmental or intellectual deficiencies in young children. The test measures five weighted factors and consists of both verbal and nonverbal subtests. The five factors being tested are knowledge, quantitative reasoning, visual-spatial processing, working memory, and fluid reasoning. Raw scores for each subtest within the overall test are converted to scaled scores using a table within each test manual to look up equivalents. Scaled scores are then converted to standard scores (range=50-150). Higher scores suggest a higher level of functioning related to each category.

The ABAS-II is designed to evaluate whether an individual displays various functional skills necessary for daily living without the assistance of others. Thus, this instrument focuses on independent behaviors and measures what an individual actually does, in addition to measuring what he or she may be able to do. In addition, the ABAS-II focuses on behaviors an individual displays on his or her own, without assistance from others. The Parent/Primary Caregiver Form is a comprehensive, diagnostic measure of the adaptive skills that have primary relevance for the functioning of infants, toddlers, and preschoolers in the home and other settings, and can be completed by parents or other primary care providers. Each composite or domain score is determined by summing the appropriate scaled scores and then determining its equivalent composite or domain score by looking it up in a table located in the manual.The range for all scores is 50-150, with a higher score equaling a better outcome.
