Special procedures refers to (1) securing an airway using equipment (oesophageal obdurator airway or laryngeal mask, securing an airway using a tracheal tube, and tracheal intubation by an individual accredited in this procedure); (2) securing a venous route and transfusion via a venous route using the crystalloid solution lactate Ringer's solution and (3) drug administration using adrenaline (adrenaline administration by an individual accredited in drug administration).
CPC, cerebral-performance category, CPR, cardiopulmonary resuscitation; PCI, percutaneous coronary intervention; PVT, pulseless ventricular tachycardia; ROSC, return of spontaneous circulation.
