A Shocking Tale

The lights and tones woke me up at about half past midnight for a medical call.  It was for a 28 year old female complaining of a heart problem.  As I pulled on my gear and found the address on the wall map I thought to myself, this is either some ridiculous panic or drug/alcohol induced nonsense or someone with a congenital abnormality or other serious cardiac issue.  Because it was the witching hour and I had been asleep I was grumbling and leaning toward the former. 

En route dispatch updated us that the patient had a cardiac defibrillator and it had fired about ten times in the last fifteen minutes.  Okay, so I was wrong...it's the latter.  We arrived at the apartment and found a young woman lying in bed with her arms crossed around her chest and her eyes  closed.  She told me she was just trying to be still and relaxed so the defib wouldn't fire again.  She said she has had an AICD (Automatic Implantable Cardiac Defibrillator) for thirteen years and has never had it fire.  This was her second AICD (which she's had for the last five years) and as it turns out this particular model has a recall notice for some possibly faulty wiring.  That had to be disconcerting.


I assessed vitals, ekg, and got some additional history from her.  She was awoken from sleep by the fist shock but had no prior symptoms, stress, or unusual activity. Her ekg actually looked fine although we would have to wait for the ambulance to get a more definitive 12 lead ekg.  This is a little frustrating because I am a 12 lead trained medic but we don't yet have the cables on our monitors to allow us to do them.  My department is currently training all of our medics in 12 lead acquisition which is excellent.  But, until that's done I have to wait to use my training.  In any case, the scene was calm and my patient was cardiac symptom free: no pain other than residual pain from being repeatedly electrocuted, good BP, good pulse and rhythm.  It was certainly looking like she got one of the defective defibrillators.  Unfortunately there wasn't much I could do for her.  Her chest pain was only a three out of ten and only caused by the shocks, she couldn't have morphine and my other pain management drug wouldn't do much in this situation.

The ambulance arrived and we were disconnecting our equipment from her when she suddenly screamed and sat bolt upright.  The AICD had fired again.  I was at her side and my firefighter had his back turned to her and was trying to coil up the long ekg wires when she screamed.  In my peripheral vision on one side I saw my patient clutching her chest and rising up and on the other side I saw a tangle of wires flying into the air as my firefighter jumped like a startled cartoon cat.


It would have been funny except my patient was now crying and scared to move.  This means she didn't want to get up and onto the waiting ambulance gurney.  This means we have to pick her up and carry her to the gurney.  Which means I have to get behind my patient and wrap my arms around her holding onto her wrists and pulling her arms into her chest while another firefighter holds her legs under the knees and we take her down the hall this way.  She was young and light and I wasn't worried about the lift.  I also wasn't too worried about the defib, it shouldn't really be strong enough to hurt me even if it fires while I'm carrying her (at least I hoped it wouldn't - I didn't really know how powerful the thing was).  I just didn't want either of us to drop her if she suddenly screamed and jerked again with the sudden shock.  Fortunately we made it to the gurney and the ambulance took off without any more shocks.

All The King's Horses


"Engine 41: Respond for a 22 year old female with an eye injury".

This call was pretty close to the station and we arrived very quickly. So quick, in fact, as to not get the update that the eye injury was caused by an egg. Yes, an egg.

Don't worry if you're feeling confused, I was too. All will be made clear.

We arrived and were greeted at the door by a young woman holding a wet cloth to her eye. I led her into the nearest room and had her take a seat. The nearest room happened to be the kitchen where she proceeded to tell us that she had been microwaving an egg and when she set it on the counter it exploded in her face. And yes, I realize there are numerous jokes and puns to be made here, like "I guess the yolk is on her", etc, but I'm not going to stoop that low. I glanced around the kitchen and saw bits of egg shrapnel everywhere. There was exploded egg all over the ceiling and the counters.

She didn't say so and I wasn't going to make her feel worse by asking if she had actually placed a raw egg in the microwave to hard-boil it, but that is obviously what had happened. The same principle behind popcorn popping and tanker truck explosions is at work here: it is called a BLEVE or Boiling Liquid Expanding Vapor Explosion. Simply put, the liquid inside a closed container vaporizes and expands thereby increasing the pressure inside and causing a failure of the container and a subsequent explosion. She had somehow nuked this egg for the perfect amount of time so as to not explode harmlessly in the microwave but to delay detonation until she had crossed the kitchen with it and set it down on the counter. The flash-bang of egg grenades if you will.

I removed the cloth to see the extent of her injury and found her eye to be completely swollen shut. I could just barely get it open enough for a cursory examination. It was bloodshot and irritated but I couldn't see any actual shrapnel. We spiked an I.V. bag and tilted her head to the side and just used the tubing to run cool saline into her eye to her great relief. She had already done a pretty good job of flushing it with cool water when it first happened but she was still in pain.

By the time the ambulance arrived she could almost open her eye all the way, although only briefly. We passed off our irrigation contraption to the ambulance medics so they could keep flushing her eye en route to the hospital. I got back in my engine, shook my head, and headed back home.


Here's a link to an exploding egg video on youtube. Just imagine looking right at the egg in a bowl when it blows:
