Calcium

calcium

I rank Calcium 23 out of 33 drugs I carry.

I don’t use calcium very much, but there is one situation I always reach for it in — cardiac arrest in a diaylsis patient. While we don’t have labs in the field, a dialysis patient is a possible bet to be hypocalcemic and/or hyperkalemic, and calcium can save lives if they are. We can also consider calcium in the setting of calcium channel blocker overdose.

I can’t claim any arrest saves using it, but I have had quite a number of return of spontaneous circulation and hospital admissions after I have used it.

We can also use calcium for symptomatic bradycardia due to suspected calcium channel blocker overdose with medical control orders. I have never used it for this.

Here’s an excerpt from my novel, Mortal Men, that includes a call where Calcium is used:

“The real rivalry between Troy and Ben started the day Sidney coded,” Joel said. “Sidney Seuss — he’s the guy in the portrait in the front office. He founded the place. A real old time ambulance man. He was just getting ready to start his dialysis treatment – he had his own machine in his office – when he crumpled to the ground. His secretary screams. When Ben gets there, he sees Sidney lying on the carpet. He’s blue. No breathing, no pulse. Ben rips Sidney’s shirt open, puts the paddles on his chest. He’s in v-fib. He shocks him. 200 Joules. No change. Shocks him again. 300 Joules. Nothing. 360. Nothing.

“The secretary starts CPR while Ben goes for the airway. Sidney’s a big broad guy with no neck. A difficult tube. Ben’s looking down into his throat, trying to move his tongue out of the way. He sees the chords for a moment, passes the tube. Puke comes up. He’s in the esophagus.

“That’s when Troy and I come in,” Victor said. “We’d been in the office resupplying. Troy sidesteps the puke, and while Ben tries again, Troy slams an IV in Sidney’s arm. Ben’s still struggling with the tube, Troy says, ‘Let me try.’ He takes the scope from him. Then like that — ‘I’m in,’ he says. Ben pushes epi and lidocaine into the IV line. They shock him again 360 joules. No change.

“’Calcium,’ Troy says.

“‘Calcium?’ Ben says. We carry it, but it’s not in the routine protocol.

“‘Calcium. His kidneys suck.’

“Ben goes ahead and gives it to him. They shock him again.

“Ben looks at the monitor — sees a rhythm. You don’t have to feel a pulse. You can just look at his neck and see it pounding.

“Then Sidney opens his eyes and he’s looking right up at Troy. He looks a little confused like maybe he was expecting to see Satan or St. Peter. Instead Troy Johnson is the one grinning at him.

“‘Afternoon, boss,’ Troy says. ‘I see I’m not the only slacker around this place likes to get in a good snooze.’

“Troy was the golden boy after that. Sidney gave Troy his own dedicated ambulance, his own shift whatever hours he wanted to work, and let him pick whatever partner he wanted. Told the dispatchers no transfers for Troy. They have to leave him free for the big bad ones. The Deputy mayor coded. Troy saved him. One of the high-ranking police brass coded. Troy brought him back to life. Head of the chamber of commerce choked on a piece of meat the size of his fist; Troy yanked it out with a pair of McGill’s. The guy was well enough to give the after dinner speech.

“Every save Troy got, Sidney made a show of visiting the patient in the hospital, and bringing a photographer along. Ben wasn’t happy about it — that and the fact every time Sidney saw Ben and Troy together he ribbed Ben about it. ‘Good, I got my bodyguard here to keep my chief paramedic from killing me.’ The truth is we got some good publicity in those days. We were miracle workers. The pride of the city. Paramedics. We were all like Johnny and Roy on that old Emergency show. You could walk tall.”

“Not any more?”

“No, that’s the past. Sidney’s dead. Things are changing for the worse. They don’t get better, we could be out of business. We could all be looking for jobs. So you can understand why no one’s happy.”

  • I’m really, really enjoying the series you have going on all of these EMS medications. I’ve read every one of them. You’re a great writer and I hope that you combine all of these into a series when you’re done with this. Great stuff.

    You need to add a Tweet Meme button and a Share to Facebook button. I’ve been tweeting your stuff, but one click is easier than 10. Please?
