After a few months of general quiet we were called on full arrests on two shifts in a row. The first call was a run we jumped due to our proximity. A 60 year-old woman went down at a nearby dialysis center. When we arrived the staff was performing CPR and had placed an oral airway (a J-shaped plastic piece that keeps the tongue out of the airway). She had already vomited and was bleeding from someplace in her mouth. A fire crew from my station arrived almost simultaneous with us and our backup unit arrived within a couple minutes. We immediately began the standard process for full arrests. One person takes care of the airway and another is responsible for gain vascular access so drugs can be administered. I took over the airway in this case. I prepared my tools to help me attempt to intubate the patient. Intubation is difficult under good circumstances an impossible other times. In this case the woman's jaw was clinched tight and her mouth was full of vomitus and blood. One thing they teach about intubation technique is to avoid using a person's teeth as a fulcrum when pulling back on your blade to open the throat so you can see the vocal chords. I remembered this point as I pushed the blade between her teeth and tried to get a view of her throat. Her jaw was clinched so tight I could barely slip anything between her teeth. Suddenly her upper teeth didn't look right-they were pointing off at an angle, all of them. It took me a second to realize they were dentures. After removing them I continued only to have the same thing happen with the bottom set. The intubation did not work because of how stiff the patient was so I used a King-tube. Normal intubation places a tube in between your vocal cords and uses a small balloon to seal off your trachea. The King-tube goes straight down the esophagus and uses two balloons to isolate the trachea. Both allow for ventilating a patient but only intubation fully protects the airway from aspiration. While I was working on the airway, my partner placed a humeral IO.
Recently we changed our process for vascular access. The old way involved attempting to start an IV which could be challenging because if you're heart is not beating your veins tend to go flat. If you couldn't get an IV after three attempts you would move on to placing an IO (intraosseous) needle in the tibia just below the knee. Now, we skip the IV attempts and place an IO needle in the humerus just below the shoulder. The placement in the humerus allows us to flow amazing amounts of fluid and moves drugs to the heart in seconds.
After three rounds of drugs and cpr we found her pulse had returned. As soon as we have the return of a spontaneous pulse we shift modes and begin working to maintain the patient instead of reviving them. We will even use saline fluid chilled to near freezing to start dropping a patient's core temperature. Research has found therapeutic hypothermia reduces damage to the nervous system after a heart attack. Another shift after we get a pulse back is to get on the road as quick as possible instead of continuing to work on the patient on scene. In this case we managed to get her to the hospital in much better shape than we found her. She was even beginning to move her hands and feet a little.
The next shift we were called for another full arrest just a block down from the Alamo. A man was seen clutching his chest on the sidewalk and then collapsing. This time we arrived shortly after Engine 1 with our backup close behind us. The process was the same as the last time but this patient reacted almost immediately and had a spontaneous pulse after just one round of drugs. Before we had finished writing our report at the hospital the patient had been moved from the ED to ICU for further observation/recovery.
