Usg Flashcards
(20 cards)
What is the role of ultrasound as a point-of-care diagnostic aid?
Real-time bedside scans for airway, lungs, heart, volume status, stomach contents, and trauma detection
This aids in immediate decision-making during perioperative care.
How does ultrasound enhance guided procedures?
Enhances safety and success of IV/arterial/CVC access, regional blocks, and emergency airway or drainage interventions
This improves outcomes in various invasive procedures.
What does ultrasound monitor in cardiorespiratory management?
Detects cardiac function, effusions, pneumothorax, and pulmonary edema quickly
This information guides timely management decisions.
What is the significance of fluid status estimation using ultrasound?
IVC collapsibility and lung B-lines offer informed assessment of preload and overhydration
This helps in managing fluid therapy more effectively.
What is one advantage of ultrasound in volume assessment?
IVC and cardiac scans predict fluid responsiveness more accurately than static measures
This improves patient management during hemodynamic monitoring.
How does ultrasound assist in identifying shock etiology?
Distinguishes hypovolemic, cardiogenic, and obstructive shock through focused echocardiography
This allows for targeted treatment strategies.
What is tailored fluid therapy in the context of ultrasound?
Serial US exams track response to fluid boluses, minimizing hypotension post-induction
This approach enhances patient safety during anesthesia.
What critical conditions can ultrasound detect instantly?
Identifies tamponade, pneumothorax, or edema
Often faster than clinical signs, improving emergency response.
What are the benefits of ultrasound being portable and radiation-free?
Non-invasive, usable in pre-op areas, OR, ICU, and wards without radiation risks
Enhances its applicability across various settings.
What is a cost advantage of using ultrasound compared to invasive monitors?
Less expensive than invasive monitors and avoids catheter-related risks
This makes it a more accessible option for many healthcare settings.
What is a limitation of ultrasound regarding operator skill?
Depends heavily on training—poor quality or misinterpretation possible
Operator experience significantly affects outcomes.
What type of data does ultrasound provide?
Semi-quantitative data, offering snapshots, not continuous hemodynamic metrics like CO or SVV
This limits its use in some continuous monitoring scenarios.
What factors can affect ultrasound image quality?
Obesity, gas, positioning, or PPE can impede clear imaging
These factors can lead to challenges in obtaining accurate results.
What is a limitation regarding protocol standardization in ultrasound use?
No universal guidelines exist; practices vary widely
This inconsistency may lead to variability in care quality.
How can time constraints in emergencies affect ultrasound use?
Comprehensive scans may delay treatment in critical events
Quick decision-making is essential in emergency situations.
What aspect of microcirculation can ultrasound not evaluate?
Detects macro-level fluid status but not tissue perfusion at capillary level
This limits the ability to assess local tissue health.
What is one advantage of ultrasound in shock management?
Differentiates shock types quickly
This facilitates prompt and appropriate interventions.
What is a limitation of ultrasound in monitoring procedures and complications?
Depends on image quality
Poor image quality can lead to missed diagnoses.
What are the overall practical advantages of ultrasound?
Radiation-free, portable, cost-effective
These features contribute to its increased use in various clinical settings.
What is one limitation regarding the overall practicality of ultrasound?
Semi-quantitative, standardization lacking
This can lead to inconsistent results across different practitioners.
