Case Study: Sepsis and Tachycardia (with EKGs)
Posted 10 July 2007 - 03:50 PM
Intercept with BLS crew for shortness of breath. The patient is a 45 y/o male:
Hx: "Brain Cysts," HIV+, Unknown other (family not the best reporters)
Rx: Family remembers only Morphine and Ativan
The patient presents unresponsive, GCS 4 (1 point for occasional moans). Family says (through the BLS crew, I intercepted enroute) that this mental status is baseline x 1 week. I have a hard time believing that, but thats the story. They called 911 "because it looked like he was having troube breathing."
BP: Unobtainable. Maybe a radial pulse, hard to tell.
SPO2: Wont read (?hypotension/perfusion issue)
ETCO2: 10, with good waveform
Lung sounds with diffuse rhonchi, no JVD/distal edema. Skin is warm/pink/dry at the core but mottled and somewhat cyanotic to the extremities. Pupils are sluggish to react, 3mm, with a disconjugurate gaze to the upper left (unknown baseline). Rapid trauma assess negative for DCAPBTLS. Blood Glucose is 146.
SVT at 175-190 without ectopy, generalized ischemia.
I direct assisted vents with BVM+OPA+O2. Reassessment of the lungs finds good expansion on each vent from the BVM, ETCO2 trending upward as the tachypenia is slowed down.
IV with NS wide open
I made a decision here to give Adenosine 6mg. I felt that the heart rate was too fast to be compensatory, and that reduced refilling time could be accounting for at least some of the hypotension. I realized that this patient was probably not having a primary cardiac problem, but I felt that the rate was something that needed to be addressed.
6mg didnt touch the guy-- no changes on the EKG or otherwise. We arrived at the ED before I had time to draw up 12mg.
In the hospital the patient was intubated with RSI, and promptly coded 4 times, recuscitated each time from the various (VF, VT, PEA, asystole) rhythms. When I turned in my paperwork the patient had a blood pressure in the 70s systolic, and they were mixing up an epi drip in the hopes that it would bump the pressure up. I havnt been able to follow up since, but it didnt look good.
The crossroads here was really the decision to go with adenosine. I was working with a primary clinical impression of septic shock, but believed that the heart rate was way too fast to be helping. I felt I did what I was able to.
I could also have spent my time attempting to intubate, but the patient was biting on the OPA and the BVM vents seemed to be working just fine. I didnt think it would be successful and at the moment, the airway was secure.
I suppose I could have also spent the time attempting a 2nd IV.
I would like to hear what you guys think.

Attempting to break the rhythm was not my only treatment. As I mentioned above, I was running fluids as well, along with the airway stuff.

I applaud the fact that you are willing to put yourself on the stand in front of your peers and take both the praise and criticism. I do not see this as a recurring theme with EMS providers. Many people are too prideful and self absorbed to even think about attempting to learn from their actions, bad or good. In addition, you seem quite willing to own up to your decisions right or wrong. (Not that I am telling you that what you did was incorrect, this is simply how I viewed the situation given the information.)

I think this patients tachycardia was part of a bigger picture.
I agree. ...Although at the same time I felt that the rate was possibly a problem in and of itself. Sure, it may be part of some other pathology, but that doesn't make the rate benign. Like I said before, I worried that it was contributing to the hypotension. I couldnt/wouldnt assume that it was the only cause.
I agree that cardioversion was indicated considering the patient's condition, but to be honest I sissied out on it a little bit-- mostly because I knew in the back of my mind that the tachycardia was probably not the primary problem. I decided to do a brief trial of medication first and see how that worked out. Meanwhile, I did the fluid boluses and maintained the airway.
As far as putting myself out there, thank you. I am new, I admit, and there is a lot I have yet to learn. The same is probably true of many members here. Hopefully we can all learn from these calls.
