Everyone knows that you cant always rely on dispatches information for what is really going on at a scene. Too many times you get to a call and find out that its completely different. This is nothing against dispatchers, they have to listen to peoples chaos and try and figure out what is going wrong. I wanted to share my most extreme example of this. I also am curious if anyone else has responded to calls where the problem is WAY different then what the dispatcher tells you. Awhile back, my partner and I had a call for a female, 6months OB/ in labor. At my service we get a LOT of calls like this. They are often just a "taxi ride" to the hospital because they dont have a car. Often the people are starting to have somewhat regular contractions, Water hasnt broken, etc. Even though this happens, I always treat it like its imminent delivery. We of course always bring our jump bag in "which has our OB kit in it." Fire dept first responders are already on scene. A few people at the house are crying. I think its kind of odd, but just brush it off. A family member leads us upstairs quickly. As I walk around the corner, I see the FD kneeling on the floor around a patient. At this time, I am thinking, ok this is the real thing, she must be delivering! As I walk closer and look over the FF shoulders I found the last thing I thought i would see. This young pregnant lady was in Cardiac arrest! After a quick OH ****, we gathered all our equipment and start treating Asystole. En route to the hospital we got a sinus rhthm/pulse back! The hospital did an emergency C-section, only to find the baby in cardiac arrest. In the end neither mom nor child made it. This story made me realize even more so than before, that Dispatchers can not always get reliable information. That you need to expect anything.
