Assessment and Evaluation of the High Risk Neonate: The NICU Network Neurobehavioral Scale
Published on: August 25, 2014
Summary
Infant cry analysis can detect health issues. Specific cry patterns, like "glottal instability," are linked to high bilirubin and respiratory problems, potentially aiding early diagnosis.
Area of Science:
- Neonatal physiology
- Acoustic analysis
- Computational linguistics
Background:
- Infant cry is a complex neurophysiologic function.
- Cry analysis may assess infant health status.
- A computational model can link cry acoustics to infant characteristics.
Purpose of the Study:
- To develop and test a model for infant cry analysis.
- To correlate acoustic cry properties with infant health.
- To evaluate cry analysis as a potential screening tool.
Main Methods:
- Developed a computer-based signal processing system for cry analysis.
- Analyzed cries from 87 infants after a standardized pain stimulus.
- Grouped cry features into eight evaluative tests.
Main Results:
- "Glottal instability" found in 11/12 infants with high bilirubin (10-20 mg/100 ml).
- 14/17 infants with various problems showed multiple cry abnormalities.
- Ten of 12 infants with respiratory disease had a unique cry pattern.
- Vocal tract constriction features noted in 3 infants; 2 later died of SIDS, 1 had sibling with apnea.
Conclusions:
- Infant cry analysis shows promise for detecting abnormalities.
- Cry analysis may serve as a valuable screening test.
- Potential to identify infants at risk for sudden infant death syndrome (SIDS).

01:30Assessment of Airway, Skin Color, and Use of Accessory Muscles
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

01:31Respiratory System Abnormal Finding II: Palpation and Auscultation
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:14Piaget's Stage 1 of Cognitive Development
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

01:30Socioemotional Development during Infancy
Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

01:20Attachment
Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that physical...
