Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

1.4K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Real Time RT-PCR02:57

Real Time RT-PCR

65.1K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...

Speed of a Transverse Wave01:13

Speed of a Transverse Wave

4.0K
The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length.
One of the key properties of any wave is the wave speed. Light...

General Anesthesia: Overview01:24

General Anesthesia: Overview

667
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Stages of General Anesthesia01:22

Stages of General Anesthesia

1.7K
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Deformations in a Transverse Cross Section01:21

Deformations in a Transverse Cross Section

642
When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...

Area of Science:

  • Anesthesiology
  • Medical Imaging
  • Surgical Procedures

Background:

  • Ultrasound-guided spinal anesthesia is an emerging technique.
  • Traditional spinal anesthesia carries risks and requires expertise.
  • A novel approach may improve procedural success and safety.

Purpose of the Study:

  • To introduce and evaluate a new paramedian transverse approach for real-time ultrasound-guided spinal anesthesia.
  • To assess the feasibility of performing the block with the dominant hand in various patient positions.
  • To determine the initial success rate and procedure time of this novel technique.

Main Methods:

  • Development of a new paramedian transverse approach for ultrasound guidance.

  • Real-time ultrasound visualization during spinal needle insertion.
  • Assessment of first-pass success rate and procedure duration.

Main Results:

  • The developed paramedian transverse approach for ultrasound-guided spinal anesthesia is a promising technique.
  • High first-pass success and acceptable procedure time were observed in preliminary patient experience.
  • Further randomized controlled trials are necessary to compare its effectiveness and safety against blind techniques and other ultrasound-guided methods.
