Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance01:14

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

698
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Personality Disorders: Narcissistic and Avoidant01:26

Personality Disorders: Narcissistic and Avoidant

859
Narcissistic and avoidant personality traits represent two contrasting patterns of behavior that significantly influence social interactions and self-perception. While individuals with narcissistic disorder seek admiration and validation, individuals with avoidant personality disorder withdraw due to fear of judgment.
Characteristics of Narcissistic Personality Disorder
Narcissistic individuals exhibit an inflated sense of self-importance and an excessive need for admiration. They are often...

Avoidance Learning and Learned Helplessness

2.7K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Directing Effect of Substituents: meta-Directing Groups

6.1K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Primary Motives: Sleep, Sex, and Pain Avoidance

5.9K
Primary motives such as sleep, sex, and pain avoidance are crucial drivers of behavior in humans and animals. These motives ensure survival, reproductive success, and overall well-being by prompting actions that meet essential bodily needs.
Sleep is a fundamental physiological drive that fosters a state of restfulness crucial for several bodily functions. It facilitates body restoration, the process by which the body repairs, rejuvenates, and maintains itself during sleep, including memory...

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Hypothermia Research

Background:

  • Deep hypothermia is used in congenital cardiac surgery to protect organs by reducing metabolic demand and oxygen needs.
  • However, deep hypothermia has significant deleterious cerebral and extracranial side effects.
  • These side effects necessitate exploring alternative perfusion strategies.

Purpose of the Study:

  • To reexamine the therapeutic value of hypothermia in congenital cardiac surgery.
  • To describe the potential advantages of mild hypothermia compared to deep hypothermia.
  • To present a practical and reproducible method for multisite perfusion under mild hypothermia.

Main Methods:

  • Implementation of multisite perfusion.
  • Utilizing mild hypothermia at a target temperature of 32°C.
  • Focus on a practical and reproducible approach.

Main Results:

  • Mild hypothermia (32°C) presents potential advantages over deep hypothermia.
  • The described multisite perfusion method is practical and reproducible.
  • This approach aims to mitigate the side effects associated with deep hypothermia.

Conclusions:

  • Mild hypothermia is a viable alternative to deep hypothermia in congenital cardiac surgery.
  • Multisite perfusion under mild hypothermia offers a promising strategy for organ protection.
  • Further research into this technique can improve patient outcomes in pediatric cardiac procedures.
