Vascular Access Ultrasound — Flashcards

Flashcard 1: The insertion and use of catheters for continuous spinal anesthesia _____ increase the risk of PDPH

Answer: does not (does/does not)

Flashcard 2: _____ needle is used in epidural anesthesia and has a blunt curved tip (Huber tip), which helps prevent accidental dural rupture

Answer: Tuohy

Flashcard 3: In a case of venous air embolism (VAE) during craniotomy, the immediate next step of management is to _____ to limit air entry to chest circulation.

Answer: compress the jugular vein

Flashcard 4: Patient is placed in _____ position while performing proof puncture (Antral lavage) under GA

Answer: Rose's

Flashcard 5: Which catheter is used to measure pulmonary capillary wedge pressure (PCWP) and cardiac output via thermodilution?

Answer: Swan-Ganz catheter (Pulmonary artery catheter)

Extra: The Swan-Ganz catheter is a multi-lumen flow-directed catheter with a balloon at the tip. It is used to measure: 1. Right atrial pressure (CVP) 2. Right ventricular pressure 3. Pulmonary artery pressure 4. Pulmonary capillary wedge pressure (PCWP) 5. Cardiac output (via thermodilution)

Flashcard 6: The most common complication of a central line insertion below the clavicle is _____

Answer: Pneumothorax

Extra: For **subclavian vein** catheterization (infra-clavicular), **pneumothorax** is the most common mechanical complication (approx 1.5–3%). In contrast, for **internal jugular vein** catheterization, **arterial puncture** (carotid artery) is the most common complication (approx 6–9%).

Flashcard 7: The incidence of PDPH is _____ when the needle bevel is placed in the long axis of the neuraxis

Answer: lesser (more/less)

Flashcard 8: _____ is the most commonly used depth of anesthesia monitor.

Answer: Bispectral index
