Can anyone describe what happens during drainage process

[unblock]

4. I have actually seen this in an emergency room when I was the emt

This was for a collapsed lung, so the fluid they were draining was technically outside her lung, but it's probably a very similar procedure when it's inside.

She was conscious, local an anesthesia only afaik. They clean the area, take a big needle in between the ribs to the location they're trying to drain, pull back on the needle to pull out the liquid, stick a bandage on it and done.

If it's not an emergency, maybe they ultrasound to visualize it. Otherwise I think they may have to do a bit of trial and error with the needle.

The casein saw, she did not seem particularly bothered by the needle, though she was in obvious distress from trying to get all her oxygen from only one working lung.

My job was to hold her hand, talk to her to distract her, and keep her from rolling over (if she tried to look at the needle area, it would move her out of position)
