Eight new papers today — here are the top four. Paper one — most children needing an ambulance for pain get poor pain management, and preparedness is the fix. Paper two — a Spanish stroke triage scale holds up five years on, picking who goes straight to the clot-removal lab. Paper three — ST elevation after cardiac arrest tracks an acute blocked artery, but no ST elevation doesn't rule one out. Paper four — two-thirds of survivors of refractory cardiac arrest treated with ECMO-driven CPR are still alive five years later.

Paper one — the Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine. A realist evaluation from England, built on interviews with twenty-one ambulance clinicians, fourteen parents and carers, and nine children and young people, plus thirty-four thousand clinical records. The headline number: around sixty per cent of children and young people who need an ambulance for a painful condition experience poor pain management. The refined programme theory puts two mechanisms at the centre — clinician preparedness, meaning education, training, exposure and experience, and compassionate person-centred care: establishing privacy, providing reassurance, appearing calm, empowering the child, and challenging negative assumptions about their pain. Paediatric pain is core ambulance work everywhere in Australia, so the mechanisms travel well, whatever the drug chart looks like. The caveat — this generates theory, not effectiveness evidence, and participants were self-selected.

Paper two — BMC Emergency Medicine. A prospective observational study of one thousand nine hundred and fifty prehospital code-stroke patients in a Spanish urban network of six point seven five million people. M-DIRECT is a triage scale — a score of two or more means bypassing the nearer stroke unit for a centre capable of endovascular treatment. Five years after implementation it's performing: seventy-seven per cent sensitivity, seventy-six per cent specificity, and a positive score independently tripled the odds of actually getting the clot retrieval. Only ten per cent of treated patients needed a secondary transfer. The caveat — the scale is embedded in a Spanish system with physician involvement, and it isn't used on Australian roads. But as thrombectomy services grow here, the broader lesson stands: prehospital scales can pick these patients, and destination decisions matter.

Paper three — Resuscitation. A retrospective single-centre study from Japan, one hundred and forty-nine survivors of out-of-hospital cardiac arrest who underwent post-resuscitation angiography with a presumed culprit lesion. Those with ST elevation on the post-arrest ECG showed a more acute occlusive picture — worse flow in the culprit vessel and greater myocardial injury. Those without it more often had multivessel disease or chronic total occlusions. And ST elevation was not independently linked to neurological outcome once prehospital factors were accounted for. The number that jumps out at me is what wasn't there — no ST elevation didn't exclude a coronary culprit. That's worth stating in the handover after a resuscitation. Heavy selection here though — one centre, angiography-evaluable survivors only.

Paper four — also Resuscitation. A retrospective cohort from Minnesota and Prague: seven hundred and twenty-eight patients given extracorporeal CPR for refractory VT or VF arrest. Twenty-nine per cent survived to discharge, and among those survivors, sixty-seven per cent were still alive at five years — with good cerebral function in more than ninety per cent of those living past a year. Most deaths clustered in the first ninety days after discharge. The caveat — highly selected patients within long-established ECPR systems, and no control group. ECPR-capable centres are still scarce in Australia, so this informs destination thinking: a refractory VF arrest near one of these centres is worth a fast transport.

Quick recap. One — preparedness and compassionate care are what help kids in pain on the road. Two — M-DIRECT accurately picks clot-retrieval candidates, five years on. Three — post-arrest ST elevation tracks an acute occlusion, but its absence rules nothing out. Four — two-thirds of ECPR survivors are alive at five years.

Four more on the dashboard today, including STEMI deaths shifting prehospital and long wildfire shifts linked to broken sleep. That's the roundup for Wednesday the fourth of November. Back tomorrow.
