Out of Hospital Cardiac Arrests

Out of Hospital Cardiac Arrest Outcomes

UK statistics
> In 30% of cardiac arrest cases, resuscitative efforts are terminated at scene.
> For those who make it to hospital, resuscitation is terminated in two-thirds of the remaining 70% of patients.
> Once in hospital, of the 23% of cases who initially survive, only approximately half leave hospital alive.

This means that only 1 in 10 survive an out of hospital cardiac arrest (OHCA).

——————————————————————————————————————
Every year, in England, cardiopulmonary resuscitation is attempted in approximately 30,000 OHCA. However, these mothers, fathers, sons, daughters, grannies, grandads, husbands, wives, lovers and friends have almost a 0% chance of survival if NO bystander CPR is attempted.

So, what?

YOU can make a difference.
Current evidence suggests that only 30-40% of bystanders make any effort to resuscitate someone who they witnessed to have a cardiac arrest. YOU can change this.
——————————————————————————————————————
Countless studies have demonstrated, time and time again, that bystander CPR, regardless of its efficacy, is positively correlated with improved survival statistics.

CPR is NOT difficult.
You are not going to do any further harm, by performing CPR, to anyone who is already clinically dead – but you could make a huge difference.
Ask your school to include it in their curriculum.
Search “how to do CPR” on YouTube, and watch a 4 minute video.

Massive heart attack!

Today begins with me being enlightened about how coming from the country means I am naturally incestuous with six fingers. I can confirm that this is not true.

Anterolateral MI
Anterolateral MI ST-segment elevation in leads I, aVL, V2 – V6 with reciprocal changes in III, aVR and aVF.

We’re dispatched almost immediately to a patient in their fifties with cardiac chest pain. On arrival, they’re laid on the pavement breathing at 76 a minute and are in quite evident distress. We don’t dilly dally around. The patient is in the back of the ambulance within minutes. I  do a 12-lead ECG (a tracing of the hearts electrical activity, pictured below). The tracing confirms that the patient is having a rather significant heart attack or MI (myocardial infarction in fancy medical talk). Aspirin, clopidogrel and GTN are given, as standard, and I alert the PPCI (primary percutaneous coronary intervention) department, which is only the best part of a 50-minute drive (on blue lights). The monitor then shows my patient is in cardiac arrest. I promptly alert my colleagues. Compressions are started immediately and he is shocked twice – we achieve ROSC (return of spontaneous circulation – basically we’ve brought the patient back to life). Although by now, the patient has technically died and been resuscitated, all they keep saying is how they’re going in and out of consciousness. I think we did quite a good job. The patient is stable for the rest of the journey to the PPCI. I am allowed to watch the angioplasty, which is successful.*

Naturally, the rest of the day was fairly mundane after this bout of excitement.±

* Angioplasty carries significant risks. For example, the embolus causing occlusion in the heart can, once dislodged, travel to the brain and cause a massive stroke.
