Estas técnicas alternativas de CPR podrían estar siendo
usadas tanto por profesionales de la salud como por legos, y su realización
retrasa la realización de las compresiones torácicas. La revisión sistemática
que traemos hoy al blog, realizada por un grupo de investigadores de la
universidad británica de Coventry, analiza la evidencia publicada y concluye
que ninguna de las dos técnicas mejora la supervivencia al alta. Y también que el
golpe precordial, si se intenta, no debe demorar el inicio de las compresiones
torácicas; y que tanto la puño-percusión como la “RCP mediante tos”, si se realizan
en pacientes conscientes en el momento de aparición de una arritmia, no deben
retrasar el tratamiento de la misma. Enlace de descarga: https://drive.google.com/file/d/1ck0AyKnSLeazAadF0QtWunJRMNqkRmNY/view?usp=sharing
The so-called “cough CPR”, a deep breath followed by forceful, repeated coughing every few seconds if one senses an arrhythmia, increases aortic, left atrial and left ventricular pressures. It’s a temporising measure before definitive treatment of the arrhythmia that can only be performed by cooperative, conscious patients. There are periodic stories, often on social media, instructing members of the public to perform cough CPR, in order to ‘survive a heart attack when alone’. In these reports, ‘heart attack’ is used erroneously in place of ‘cardiac arrest’. In the other hand, a precordial thump is typically described as a single, firm impact delivered to the lower half of the sternum with the ulnar side of the fist from approximately 20 cm.
These
alternative techniques may possibly be currently used by healthcare
professionals or lay rescuers, in either the in- or out-of-hospital setting.
They may delay or be used as an alternative to chest compressions as part of ‘standard CPR’. The systematic review we bring
today, published by a group of researchers from the University of Warwick on
behalf of the ILCOR BLS Task Force, analyzes the studies regarding to these subjects,
and concludes that none of them improves survival to hospital discharge. And
also that precordial thump, if used, shouldn’t delay the onset of the chest
compressions. “Cough CPR” can be attempted, also if doesn’t cause delays in the
definitive treatment, in specific patients in monitored settings at the onset
of a potential lethal arrhytmia. Download link: https://drive.google.com/file/d/1ck0AyKnSLeazAadF0QtWunJRMNqkRmNY/view?usp=sharing
