can you knock someone out by pinching their jugular vein in their neck?

Question

My 2 y.O has large blue jugular vein on l neck. At times it bulges & other times not. Can see it pulse @ times. Had echo as a baby, no defects. Worry?

Answer 1

Only if Spock: This maneuver was popularized by leonard nimoy as spock on star trek. It is not possible to do this in reality.

Answer 2

Please don't rry: Blunt force to the neck can cause a variety of life threatening injuries, and syncope (passing out) may be the least of your worries. Carotid dissection, esophageal injury, tracheal collapse, or a head injury are all possible -- please do not punch people in the neck.

Answer 3

Probably normal: Your jugular vein will pulsate normally with each heart beat (visually at least). Exaggerated pulsation in the jugular vein can be a sign of a cardiac problem however, and should be pointed out to your doctor.

Answer 5

Neck Vein Narrowing: If you are referring to pathological narrowing, it can be the result of previous clots damaging the vein, prior catheter placement in the neck vein damaging the vein as the result of scar tissue, or because of a prior phlebitis. Non-pathological visible "collapse" of the neck veins seen externally on the skin can be caused by dehydration or certain positions (veins collapse when lying down).

Answer 6

Usually normal: When you bend over, there is more pressure on the neck veins so more blood expands them and when you stand back up or lie down, they are smaller. The lump can be checked out by your doctor but is probably just a variation in the vein wall thickness. We don't do vein treatments of neck veins. People that lift weights and have low body fat can have prominent veins in their necks and arms.

Answer 7

Traffic jam: This may indicate tj. Check with your doc if there is any problem with your "highways" to the heart. Discuss echo and ultrasound of the veins. It may or may not be useful. A highly educated doc is a good choice.

Answer 8

You're still young: To have serious medical conditions. See your dr and get examined for heart, kidney, liver, thyroid, adrenal or lymph gland abnormalities. Take care!

Answer 9

Multiple vein : Enlargement of neck veins can result from benign or serious problems. Physician review is a must. Veins become prominent due to pressure/distension. Sometimes the veins appear enlarged because the patient has limited body fat, like seen in thin singers. Distended neck veins can also be a sign of heart/valve problems, thyroid enlargement and blockage of major veins in the base of the neck or chest.

Answer 10

It depends : There are multiple factors that go into neck veins pressure.Your position whether you are lying flat , the position of the bed you are lying on whether it is flat, whether you are relaxed , if you bear down or valsalva that will distend your neck veins. Other medical factors influence this as well, but yes your vein should be flat if all of the other things are optimized to keep them flat.

Answer 11

Flat: Neck veins distend when we lie with our head lower than our heart or when we strain. With straining, the pressure within the chest increases and the blood flow through the neck veins decrease resulting in them enlarging. This is normal. Levels of hydration, genetics, outside temperature and any increase in pressure within the chest will enlarge the neck veins. Neck veins collapse with standing.
