Cardiomyopathy VII: Pre and Post Operative Nursing Management01:28

Cardiomyopathy VII: Pre and Post Operative Nursing Management

291
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Diffuse noxious inhibitory control, temporal summation and wound hyperalgesia testing are demonstrated in the obstetric patient. These tests evaluate inhibitory and excitatory mechanisms of pain processing and are here utilized to evaluate endogenous analgesia at different time-points during pregnancy and the peripartum period to help reveal individual s risk for persistent...

Operational Amplifiers

1.9K
The operational amplifier, often referred to as an op-amp, is a multifaceted building block of a circuit. This electronic component functions like a voltage-controlled voltage source and can also be used to create a voltage- or current-controlled current source. The design of an operational amplifier enables it to execute mathematical operations when external components like resistors and capacitors are linked to its terminals. An op-amp has the capacity to sum signals, amplify a signal,...

Vector Operations01:20

Vector Operations

2.0K
Vectors are physical quantities that have both magnitude and direction. The vector operations include addition, subtraction, and scalar multiplication.
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.

Operant Conditioning01:21

Operant Conditioning

2.7K
Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

Modes of Operations of BJT

2.0K
A Bipolar Junction Transistor (BJT) is a versatile component in electronics, functioning in four distinct modes based on the biasing of its junctions: active, saturation, cut-off, and inverted modes.
Active Mode: The most common mode for amplification, the active mode features a forward-biased emitter-base junction and a reverse-biased base-collector junction. This setup enables electrons to be injected from the emitter to the base while blocking the majority carriers at the collector. The...

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Pediatric Neurology

Background:

  • Hemispherotomy is a surgical procedure to disconnect cerebral hemispheres, used for intractable epilepsy.
  • Neurological conditions can lead to strabismus (misaligned eyes).
  • This study investigated the potential link between hemispherotomy and post-operative strabismus.

Purpose of the Study:

  • To determine if hemispherotomy surgery causes strabismus in patients with medically intractable epilepsy.
  • To assess the incidence and characteristics of post-operative strabismus following hemispherotomy.

Main Methods:

  • The Hirschberg test was performed on 19 patients before and after hemispherotomy.
  • Sixteen pediatric patients (mean age 12.2 years) who underwent hemispherotomy were included in the analysis.

Main Results:

  • A significant widening of the angle between the eyes was observed post-surgery (p=0.025).
  • Post-operative strabismus was confirmed in 56% of patients via the Hirschberg test.
  • Intermittent strabismus was reported by caregivers in 63% of patients.
  • Patients over 12 years old did not exhibit post-operative strabismus on the Hirschberg test.

Conclusions:

  • Hemispherotomy can induce or exacerbate strabismus in pediatric patients.
  • The findings highlight a potential ophthalmological complication of this epilepsy surgery.
