[Pharmacotherapy in resuscitation].

Although pharmacologic intervention has traditionally been a mainstay in the treatment of circulatory collapse and cardiac arrest, a critical reappraisal of the relevant literature does not support this stance in every case. During cardiac arrest, medications take second place to other forms of intervention: initiation of basic life support with ventilation [100% oxygen!], chest compression and defibrillation if indicated. Epinephrine is still the drug of choice in all types of cardiac arrest. Atropine is recommended for asystole and pulseless electrical activity [PEA] with bradycardia, while lidocaine has a place in the therapy of persistent ventricular fibrillation. Sodium bicarbonate is of only limited benefit in special cases.
