[Utility of vasopressin in cardiopulmonary resuscitation]. / Utilidad de la vasopresina en la resucitación cardiopulmonar.

Many vasopressants have been studied in cardiopulmonary resuscitation (CPR) to increase cerebral and coronary perfusion. Although there is a debate on the utility of epinephrine, this is the one that has been used historically, above all after verifying that other agents such as norepinephrine, metoxamine or phenylephrine, have not been shown to be more effective. Currently, due to the good experimental results, the use of vasopressin (ADH) in CPR is being evaluated. However there is little (only three studies) and debated evidence based on randomized clinical trials (norepinephrine or ADH) in humans. Once these are reviewed, it can be concluded: The results of the three randomized studies in humans obtain different results regarding the utility of ADH in cardiorespiratory arrest (CRA) secondary to ventricular fibrillation, electro-mechanical dissociation or asystole. More prospective studies are needed to know the role of ADH in prolonged CRA and in asystole, that may be the subgroups that can benefit the most from this drug. The neurological repercussion of a drug in the context of CRA should be evaluated before its inclusion in the CPR guides.

Muchos son los vasopresores estudiados en resucitación cardiopulmonar (RCP) para aumentar la presión de perfusión cerebral y coronaria. A pesar de que existe controversia sobre la utilidad de la adrenalina, ésta es la que históricamente se ha utilizado, sobre todo tras la comprobación de que otros agentes como la noradrenalina, metoxamina o fenilefrina no han demostrado ser más efectivos. Actualmente, debido a los buenos resultados experimentales, se está valorando la utilidad de la vasopresina (ADH) en la RCP. Sin embargo existe poca (sólo tres estudios) y controvertida evidencia basada en ensayos clínicos aleatorizados (adrenalina o ADH) en seres humanos. Una vez revisados éstos, se puede concluir lo siguiente: Los resultados de los tres estudios aleatorizados en seres humanos obtienen resultados distintos respecto a la utilidad de la ADH en la parada cardiorrespiratoria (PCR) secundaria a fibrilación ventricular, disociación electromecánica o asistolia. Son necesarios más estudios prospectivos para conocer el papel de la ADH en la PCR prolongada y en la asistolia, que tal vez sean los subgrupos que más se puedan beneficiar de este fármaco. La repercusión neurológica de un fármaco en el contexto de la PCR debe evaluarse antes de su inclusión en las guías de la RCP
