This is the first (of a series) of literature reviews dedicated to a particular topic of Emergency Medicine clinical life.

We tried to give a deep look to all the articles that had a relevance for a particular argument in this year, and made some considerations regarding the emerged evidences . All the articles are full text end ready to be downloaded.

The first edition is focused on the “king argument” for an emergency medicine and critical care professional:

Cardiac Arrest

Chest compressions

This year the importance of chest compressions in CA was confirmed and even emphasized as one of the few (along with defibrillation) really wothy intervention to perform during CPR.

• Chest Compression Alone Cardiopulmonary Resuscitation Is Associated With Better Long-Term Survival Compared with Standard Cardiopulmonary Resuscitation
• Chest compression depth and survival in out-of-hospital cardiac arrest

Mechanical Devices

The “black year” for mechanical devices saw 3 major trials finding no difference in outcome between mechanical and (good quality) manual chest compressions. Still remains the subjective (personal) impression that mechanical devices are of some utility for the human resources management and  transport during CPR.

• Manual vs. integrated automatic load-distributing band CPR with equal survival after out of hospital cardiac arrest. The randomized CIRC trial
• Mechanical chest compressions and simultaneous defibrillation-vs-conventional cardiopulmonary resuscitation in-out-of-hospital cardiac arrest The LINC RCT
• Do Mechanical Devices Improve Return of Spontaneous Circulation Over Manual Chest Compressions in Out-of-Hospital Cardiac Arrest
• Prehospital Randomized Assessment of a Mechanical Compression Device in Cardiac Arrest (PARAMEDIC)

Vasoactive (and other) drugs

Like (and perhaps more) than for mechanical devices, 2014 signed a really bad year for epinephrine.

Lack of evidence on his utility and emerging ones on detrimental effects, accompanied this “historical” drug through the year that preludes to new 2015 CA Guidelines. Will epinephrine still be there at the end of this 2015? Or new emerging trends on use of steroids and vasopressin will prevale at the end?

• Vasopressin, Steroids, and Epinephrine and Neurologically Favorable Survival After In-Hospital Cardiac Arrest
• Epinephrine, vasopressin and steroids for in-hospital cardiac arrest: the right cocktail therapy?
• Glucocorticoids as an Emerging Pharmacologic Agent for Cardiopulmonary Resuscitation
• Epinephrine in Cardiac Arrest and Patients Outcomes
• Adrenaline for out-of-hospital cardiac arrest resuscitation- A systematic review and meta-analysis of randomized controlled trials
• Adrenaline (epinephrine) dosing period and survival after in-hospital cardiac arrest- A retrospective review of prospectively collected data
• Time to administration of epinephrine and outcome after in-hospital cardiac arrest with non-shockable rhythms: retrospective analysis of large in-hospital data registry
• Does Calcium Administration During Cardiopulmonary Resuscitation Improve Survival for Patients in Cardiac Arrest?

ECLS

And after interventions that are loosing evidence in the years, new future prospectives for the management of CA patients, comes from Extra-Corporeal Membrane Oxygenation that gives renewed hopes of better survival and good neurological outcome, despite initial difficulties and skepticism.

• Extracorporeal cardiopulmonary resuscitation versus conventional cardiopulmonary resuscitation in adults with out-of-hospital cardiac arrest- A prospective observational study
• An optimal transition time to extracorporeal cardiopulmonary resuscitation for predicting good neurological outcome in patients with out-of-hospital cardiac arrest- a propensity-matched study

Outcome and prognostication

• Exploring which patients without return of spontaneous circulation following ventricular fibrillation out-of-hospital cardiac arrest should be transported to hospital
• Predicting the lack of ROSC during pre-hospital CPR- Should an end-tidal CO 2 of 1.3 kPa be used as a cut-off value
• Shorter time until return of spontaneous circulation is the only independent factor for a good neurological outcome in patients with postcardiac arrest syndrome
• Survival rates in out-of-hospital cardiac arrest patients transported without prehospital return of spontaneous circulation: An observational cohort study
• Trends in Short- and Long-Term Survival Among Out-of-Hospital Cardiac Arrest Patients Alive at Hospital Arrival
• Early coronary angiography and induced hypothermia are associated with survival and functional recovery after out-of-hospital cardiac arrest
• Angiography Urged in All Resuscitated Out-of-Hospital Cardiac Arrest

Therapeutic Hypothermia

New era for the post-resuscitative care! Less oxygen, lower tidal volume and last, but not least, less cooling. And, while this year will give us some answers about intra-arrest cooling, now we know that 33°C is equally effective as 36°C and is no longer recommended in post ROSC patients! Maybe….

• Effect of Prehospital Induction of Mild Hypothermia on Survival andNeurological Status Among Adults With Cardiac Arrest A Randomized Clinical Tria.pdf
• Targeted Temperature Management Processes and Outcomes After Out-of-Hospital Cardiac Arrest- An Observational Cohort Study
• From therapeutic hypothermia towards targeted temperature management: a decade of evolution

Other

Questa settimana su MEDEST Review:

Do Mechanical Devices Improve Return of Spontaneous Circulation Over Manual Chest Compressions in Out-of-Hospital Cardiac Arrest

Nessun chiaro beneficio sull’outcome (ma anche nessun peggioramento), molti studi mai pubblicati (anche se menzionati sui siti dei costruttori), fanno dei device per la compressione meccanica del torace degli oggetti controversi ed ancora tutti da scoprire. Nuovi e più rigorosi studi attesi a breve faranno luce sull’argomento.

The Effect of Ketamine on Intracranial and Cerebral Perfusion Pressure and Health Outcomes- A Systematic Review

E se qualcuno avesse ancora dei residui culturali del passato riguardo all’uso della Ketamina nel trauma, ecco una buona occasione, speriamo quella definitiva, per aggiornare le proprie conoscenze. Review sistematica di tutte le evidenze disponibili che dimostra coem nessun effetto negativo sull’outcome sia collegato all’uso della Ketamina nel paziente critico.

Effect of treatment delay, age, and stroke severity on the effects of intravenous thrombolysis with alteplase for acute ischaemic stroke: a meta-analysis of individual patient data from randomised trials

Da NINDS a IST 3 il cammino  del trombolitico nello stroke è stato costellato di studi controversi e negativi, più che di evidenze univoche e convincenti (leggi anche: L’uso del trombolitico nello stroke. Stiamo giocando con la salute dei nostri pazienti?, Cronostoria dei trial sulla trombolisi nello stroke ischemico, rt-PA e Stroke: IST-3 l’analisi dei risultati). In questa meta-analisi che prende in considerazione tutti gli studi attualmente disponibili si evidenzia il beneficio del trombolitici se somministrato entro le 4,5 ore in tutte le categorie di pazienti. Fermo restando la serietà del metodo, permettete alcuni dubbi sul confronto tra popolazioni diverse e sul fatto che nell’articolo non sono illustrati i risultati dei singoli studi, ma solo l’aggregato dei dati. A tutti voi l’ardua sentenza.

Does Calcium Administration During Cardiopulmonary Resuscitation Improve Survival for Patients in Cardiac Arrest?

Negli anni e nelle varie edizioni delle Linee Guida ALS il calcio, nelle sue varie forme, ha sempre giocato un ruolo limitato a situazioni di ACR particolari. In questa review si prendono in considerazione tutti gli studi che riguardano la somministrazione del Calcio in ACR ed il suo effetto sull’outcome. Le conclusioni evidenziano come non ci siano evidenze di beneficio sull’outcome ma anche come tutti gli studi disponibili siano stati condotti in modo non uniforme e che quindi questo argomento va ancora esplorato in modo rigoroso in futuro per trarre conclusioni più convincenti.

Tidal Volume and Mortality in Mechanically Ventilated Children- A Systematic Review and Meta-Analysis of Observational Studies

L’avvento della Lung protective ventilation ha da alcuni anni cambiato l’approccio al paziente sottoposto a ventilazione meccanica. In particolare l’utilizzo di bassi volumi correnti si è visto come sia correlata ad una  aumento della sopravvivenza nei pazienti adulti. In questa meta-analisi di studi osservazionali che prende in considerazione i pazienti pediatrici si evidenzia come le evidenze in merito non siano altrattanto solide per l’etereogeneicità dei dati degli studi disponibili. Quindi quello che è un cardine oramai consolidato per l’adulto necessita di ulteriori evidenze prima di diventare tale anche per il paziente pediatrico.

Observational study of the success rates of intubation and failed intubation airway rescue techniques in 7256 attempted intubations of trauma patients by pre-hospital physicians

Il più ampio database di gestione delle vie aeree in ambito preospedaliero esaminato fin’ora. Percentuale di successo dell’intubazione 99,3%. I non anestesisti hanno il doppio della probabilità di utilizzare presidi alternativi (fortunatamente). Questi solo alcuni degli spunti che si possono ricavare dalla lettura di questa fondamentale risorsa.
