Review[Cardiopulmonary resuscitation: the essential of 2015 guidelines].
Cardiopulmonary resuscitation (CPR) guidelines have been updated in October 2015. The 2010 guidelines are reaffirmed: immediate call for help via the local dispatch center, high quality CPR (frequency between 100 and 120/min, compression depth between 5 and 6 cm) and early defibrillation improve patient's survival chances. This article reviews the essential elements of resuscitation and recommended advanced measures.

Sodium chloride 0.9%, often incorrectly called physiological saline, contains higher concentration of chloride compared to plasma. It is known that the administration of sodium chloride 0.9% can cause hyperchloremic metabolic acidosis in a reproducible manner. The elevated chloride concentration in 0.9% NaCl solution can also adversely affect renal perfusion. ⋯ For these reasons, the use of 0.9% NaCl solution is raising attention and some would advocate the use of a more "physiological" solution, such as balanced solutions that contain a level of chloride closer to that of plasma. Few prospective, randomized, controlled trials are available today and most were done in a perioperative setting. Some studies suggest that the chloride excess in 0.9% NaCl solution could have clinical consequences; however, this remains to be established by quality randomized controlled trials.
