Assessment of Respiration01:23

Assessment of Respiration

1.8K
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Assessment of Diffusion and Perfusion

1.5K
Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this...

Summary

Skin conductance (SC) did not show increased pain responses in preterm infants during Less Invasive Surfactant Administration (LISA). Findings suggest SC may not be a reliable pain indicator in neonates, highlighting the need for better objective pain assessment methods.

Area of Science:

  • Neonatal care
  • Pain assessment
  • Physiological monitoring

Background:

  • Less Invasive Surfactant Administration (LISA) is standard for surfactant deficiency.
  • Analgosedation protocols for LISA require further investigation.
  • Objective pain assessment in preterm infants remains a challenge.

Purpose of the Study:

  • To evaluate skin conductance (SC) as an objective pain measure during LISA in preterm infants.
  • To compare SC measurements with Neonatal Pain, Agitation and Sedation Scale (N-PASS) scores.
  • To assess the reliability of SC for procedural pain detection in neonates.

Main Methods:

  • Prospective cohort study of preterm infants (≥27 weeks gestation).
  • Pain assessed via skin conductance (SC) and blinded Neonatal Pain, Agitation and Sedation Scale (N-PASS) scoring.
  • Primary outcome: change in SC peaks per second (PPS) during key procedural events.

Main Results:

  • SC-PPS did not significantly increase during most LISA events, except for nasopharyngeal tube insertion, which was not significant after age adjustment.
  • N-PASS scores indicated pain during nasopharyngeal tube insertion and laryngoscopy.
  • A weak correlation was observed between SC and N-PASS scores (Kendall's τB = 0.17).

Conclusions:

  • Skin conductance monitoring did not reflect increased pain during LISA, despite higher N-PASS scores.
  • SC may have technical limitations for pain assessment in preterm infants immediately post-birth.
  • Further research is needed to validate objective pain assessment tools for neonates.
