Ultrasound I: Abdominal Ultrasonography01:20

Ultrasound I: Abdominal Ultrasonography

2.5K
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...

Ultrasonography

8.3K
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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

771
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Area of Science:

  • Medical Education
  • Anesthesiology
  • Ultrasound Training

Background:

  • Improving the accuracy of ultrasound-guided airway structure identification is crucial for anesthesia procedures.
  • Traditional methods may not be sufficient for comprehensive skill acquisition in sonoanatomy.
  • Novel training tools are needed to enhance the proficiency of anesthesia residents and staff.

Purpose of the Study:

  • To compare the effectiveness of hands-on gel phantom training versus instructional video methods.
  • To evaluate the improvement in identifying airway structures using ultrasound.
  • To assess the impact on anesthesia residents and staff members' sonoanatomy skills.

Main Methods:

  • A randomized controlled trial was conducted in a simulation laboratory setting.
  • Fifty-four participants (anesthesiologists and residents) were randomized into control, video training, or gel phantom training groups.
  • Skills were assessed at baseline and follow-up (14-24 days) for identification of thyroid cartilage, cricoid cartilage, cricothyroid membrane, and tracheal rings.

Main Results:

  • Both gel phantom and video training methods demonstrated a significant learning effect compared to standard training.
  • No statistically significant difference in overall airway structure identification success was observed between the video and gel phantom training groups.
  • Skills retention was comparable between the two training modalities at follow-up.

Conclusions:

  • Both low-cost airway gel phantoms and instructional videos are effective single-session training tools.
  • These methods can enhance knowledge and skills for ultrasound identification of upper airway anatomy.
  • Both approaches offer viable options for improving sonoanatomy proficiency in anesthesia personnel.
