Three retrospective emergency care studies examine suspected STEMI pathways, pelvic binder mechanics and metaraminol around intubation. Their findings highlight why diagnostic confirmation, predicted biomechanical effects and short-term blood pressure changes must not be mistaken for proven clinical benefit.

Troponin elevation identifies myocardial injury, but infarction also requires evidence of acute ischaemia. Serial results, ECG changes and the clinical history distinguish injury, infarction and unstable angina, while convincing coronary occlusion may require reperfusion before troponin results return.

Older adults with abdominal pain may have significant pathology despite limited tenderness, early ambulatory ECG monitoring detects more arrhythmias without reducing recurrent syncope, and shared video laryngoscopy can help supervisors correct accumulating technical errors during paediatric intubation.

Pupil size and reactivity must be interpreted in context: light–dark differences help localise anisocoria, evolving changes can signal intracranial deterioration, and fixed pupils after cardiac arrest require delayed, confounder-free multimodal prognostication rather than premature conclusions.

Three papers are appraised through a pre-hospital and trauma lens: intermittent-bolus maintenance of anaesthesia, National Early Warning Score versus shock index in trauma, and rocuronium dosing for rapid sequence intubation, with close attention to confounding and reliable post-intubation care.

Emergency, critical-care and prehospital teams get an evidence update on advanced trauma interventions, post-cardiac arrest oxygen and necrotising soft tissue infection. Patient-level scene delay, early avoidance of hypoxia, cautious oxygen titration and prompt surgical escalation are prioritised over service-level averages, scoring systems or reassuring early imaging.

Emergency, prehospital and ENT teams get a practical neck-stoma airway framework. It distinguishes tracheostomy from total laryngectomy and covers oxygen delivery, removal of external devices and inner cannulas, soft suction-catheter patency checks, cuff deflation and preservation of tamponade during major tracheostomy bleeding.

Emergency, critical-care and cardiology clinicians get an evidence update on early septic shock resuscitation, sodium bicarbonate during in-hospital cardiac arrest and ECG markers of right ventricular dysfunction in acute pulmonary embolism. The practical focus is repeated reassessment after initial crystalloid, early vasopressor discussion when further fluid may harm, targeted bicarbonate use and cautious integration of ECG strain markers.

An acute-care airway topic for ED, prehospital and critical-care teams managing apnoea, respiratory arrest or peri-intubation care. It keeps mask size, patient positioning, two-person seal, tidal volume, capnography and early escalation tied to whether ventilation is actually effective.

Penetrating chest trauma with shock, preserved cardiac activity and ultrasound tamponade needs a prepared route to decompression and definitive care. The critical appraisal angle is caution: selected pericardiocentesis evidence should not replace a rehearsed thoracotomy and damage-control plan.
