Welcome to the 168th FOAMed Quiz.
This ECG belongs to a patient with a pacemaker (obviously).
What is going on?
A: Failure to pace
B: Failure to capture
C: Failure to sense
What happens (most likely) if you put a magnet on a pacemaker?
A: It shuts down and will not pace anymore
B: It will pace in a fixed rate (VOO)
C: It will go into DDD mode
And the last one on pacemakers. Which of the following is a real pacemaker problem?
A: Faraway pacemaker
B: Takeaway pacemaker
C: Fadeaway pacemaker
D: Runaway pacemaker
Acute aortic dissection (AAD) requires rapid diagnosis and treatment.
On POCUS, which view can be used for the identification of an intimal flap in the aortic arch?
A: Parasternal long axis view
B: Suprasternal notch view
C: Abdominal aorta view
D: Subxyphoidal view
The correct answer is B
EMDocs covered POCUS for aortic dissection in the clinical presentation of ischemic stroke last week.
A suprasternal notch view is acquired by placing the (phased array) transducer in the suprasternal notch and rotating the length of the probe between the left sternocleidomastoid muscle and the right clavicular head. The aortic arch and its branches can be visualised.
Ultrasound assistance for lumbar punctures is used more and more regularly. It provides an opportunity to visualise and mark the spinous processes and the midline (and visualise the ligamentum flavum).
The most recent meta-analysis on this topic dates from 2019 and includes a total of 957 patients.
What did this meta-analysis show?
A: There was a statistically significant higher success rate when using ultrasound assistance versus a ‘blind’ procedure
B: There was no difference in success rate between ultrasound assistance and ‘blind’ procedure
C: There was a statistically significant higher success rate when using a ‘blind’ procedure versus ultrasound assistance
The correct answer is A
SinaiEM covered ultrasound assisted lumbar puncture last week.
In this meta-analysis, there was a statistically significant increase in success rate as well as decrease in procedure time, fewer passes with the needle, and decrease in pain score when comparing ultrasound assisted lumbar puncture versus a blind procedure.
