For RobertAlfanoNJEMT: The sternal rub is abused by everyone from my observations. It was never intended as a means to wake patients. In fact, pain stimulus applied to the sternum as part of the Glasgow coma score assessment NEVER in fact, included a full handed knuckle rub. The idea in the GCS is application of a painful stimulus to the sternum should illicit a response from the patient to reach across and remove the stimulus. This indicated a higher or lower level of brain function. This makes complete sense when you consider the next part of the assessment is to determine if the response (or level of functioning brain activity) is unilateral perhaps suggesting stroke as a differential cause of the unconsciousness. You can see that if, with each test, as they get more and more narrowly defined, there is still no response then the level of unconsciousness is worse and expressed by the falling GCS score. The stimulus itself is commonly defined as equivalent to the tip of a pen applied firmly to the sternum. Application of anything more than a pen tip level of pain is both unethical and clinically misleading because it gives an overestimate of conscious state in terms of the GCS by rousing the patient from what may well be deep unconscious due to a serious neuro event. In particular, over stimulus may have ramifications in causing a pain induced rise in HR, BP, M.A.P. and subsequently I.C.P. - a really undesirable thing to do if the cause of unconsciousness is a cerebral bleed. The classic example of this explanation is an event I witnessed involving a a stream of nurses who 1 by 1, attended a young unconscious male in the Ed brought in by paramedics who probably did the same thing, assumed a drug overdose, and applied brutal sternal rubs one after the other in order to wake him up - reason being if they couldn't, under ED policy (of which I was aware having visited this ED many times), he would need to go to ICU and obviously take up a bed. The prejudiced, judgmental and basis of this approach to patient care (I actually interceded and complained at the time as I was writing up my paperwork nearby) was completely rendered a farce when it was discovered he in fact had a neuro-bleed not a drug overdose. I really don't think I've seen a better example of the whole knuckle rub abuse scenario. Perhaps that's why its been withdrawn by so many services or maybe some EMT's have been sued? I hate anecdotal orthodoxies and Ambos are so willing to adopt them it seems. Piss poor practice and no benefit to patients if you ask me.
