Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Measurement: Derived Units

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Measurement: Standard Units

Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Varicose Veins II: Diagnostic Studies and Interprofessional Care

227
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Sound Intensity00:58

Sound Intensity

4.9K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...

Summary
This summary is machine-generated.

Pediatric intensive care unit (PICU) rounds may impair resident cognitive function, particularly memory recall. Cognitive testing is feasible in the PICU, but effects are small and vary by individual.

Area of Science:

  • Cognitive Neuroscience
  • Medical Education
  • Pediatric Critical Care

Background:

  • Cognitively demanding activities, such as Pediatric Intensive Care Unit (PICU) rounds, can lead to mental fatigue and impaired cognitive function.
  • Understanding the impact of PICU rounds on resident cognitive performance is crucial for patient safety and medical training.
  • Assessing the feasibility of cognitive testing within the demanding PICU environment is essential for research and clinical applications.

Purpose of the Study:

  • To determine if Pediatric Intensive Care Unit (PICU) rounds negatively affect cognitive task performance in residents.
  • To evaluate the feasibility of conducting cognitive function tests within the PICU setting.

Main Methods:

  • A prospective study involving residents in the PICU.
  • Cognitive function was assessed before and after rounds using the Cognitive Estimation Test (CET) and Repeatable Episodic Memory Test (REMT).
  • Tests were chosen for their sensitivity to mental fatigue.

Main Results:

  • Thirty residents participated; rounds averaged 191 minutes, involving a mean of 14.9 patients.
  • Significant decline in memory recall (REMT) was observed post-rounds (p < 0.05), with more false recalls (p=0.02).
  • No significant changes were found in Cognitive Estimation Test (CET) performance; increased susceptibility to cognitive impairment correlated with later rotation timing (r=0.42, p < 0.02).

Conclusions:

  • Pediatric Intensive Care Unit (PICU) rounds can induce cognitive impairments, primarily affecting memory, although effect sizes are small and inconsistent across tests.
  • Cognitive function testing is feasible in the PICU, providing insights into the impact of demanding clinical activities.
  • Further research is warranted to investigate the increasing susceptibility to cognitive impairment during a PICU rotation.
