Ultrasonography

4.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Ultrasound I: Abdominal Ultrasonography

180
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Summary

Brain ultrasonography shows promise for monitoring sepsis-associated encephalopathy (SAE) by detecting altered brain perfusion. However, current evidence is limited and lacks standardization for guiding treatment and predicting outcomes.

Area of Science:

  • Critical Care Medicine
  • Neurology
  • Medical Imaging

Background:

  • Sepsis-associated encephalopathy (SAE) is a common complication with significant mortality and neurological deficits.
  • Cerebral monitoring is crucial for managing sepsis patients, but non-invasive methods are needed.
  • Brain ultrasonography (US) offers a non-invasive approach for assessing cerebral status.

Purpose of the Study:

  • To review the literature on brain perfusion alterations in sepsis.
  • To evaluate the role of brain US in guiding resuscitation efforts.
  • To assess the predictive value of brain US for neurological outcomes in sepsis.

Main Methods:

  • A scoping review of three databases was conducted.
  • Included studies focused on adult sepsis or septic shock patients in the ICU.
  • Searched for randomized controlled trials, clinical trials, observational studies, and systematic reviews.

Main Results:

  • 34 studies were included, predominantly observational (85%).
  • Cerebral blood flow (CBF) alterations in sepsis showed variable results (increased, normal, or decreased).
  • Cerebral autoregulation (CAR) impairment was common, especially early in sepsis, and linked to poor outcomes, though impact clarity is lacking.

Conclusions:

  • Brain US can detect cerebral perfusion changes in sepsis, indicating its potential utility.
  • The current evidence base for brain US in sepsis is limited, lacks standardization, and requires further research.
  • More robust, standardized studies are needed to establish brain US for guiding resuscitation and predicting outcomes in SAE.
