Evaluación del uso de vasopresina para reducir la dosis de perfusión de noradrenalina

Abstract

Introduction. Shock is a common and severe problem in critical care units. Arginine vasopressin (AVP) is a vasopressor recently introduced in our environment that could be useful as second-line vasopressor in cases of shock with decreased vascular resistance refractory to norepinephrine (NE). Our objective is to verify if the administration of AVP manages to reduce the dose of NA and avoid deleterious effects associated with high doses. As secondary objectives we will study the impact of its administration on renal function, adverse effects (arrhythmias and ischemic complications) and mortality. Material and methods. A single-center, retrospective observational study was carried out in the Surgical Critical Care Unit (UCCQ) of the Hospital General Universitario Dr. Balmis (HGUDB). For the statistical analysis, the Wilcoxon test and descriptive statistics were used. A p < 0.05 was considered significant. Results. In our study sample (n=32) a significant reduction in the NE dose (p<0.001) was observed after the administration of AVP. In the subgroups with septic shock (p=0.013) and hemorrhagic shock (p=0.004), a significant reduction was also observed, while in the vasoplegic shock group after cardiac surgery with extracorporeal circulation this was not evident (p=0.062). A significant increase in the serum creatinine concentration is observed (p=0.023). The percentage of new onset arrhythmias is 6.3%, the percentage of ischemic complications 15.6%, and mortality is 59.4%. Conclusions. The use of AVP in the UCCQ of the HGUDB manages to reduce the dose of NE infusion in patients with shock with distributive characteristics refractory to conventional treatment. The role of AVP with respect to renal function in our population remains to be determined

Introducción. El shock supone un grave problema en las unidades de críticos. La arginina vasopresina (AVP) es un fármaco de reciente introducción potencialmente útil como vasopresor de segunda línea en el shock con resistencias vasculares disminuidas refractario a noradrenalina (NA). Nuestro objetivo es comprobar si su uso logra disminuir la dosis de NA evitando los efectos deletéreos asociados a altas dosis. Como objetivos secundarios estudiaremos el impacto de su administración en la función renal, efectos adversos (arritmias y complicaciones isquémicas) y mortalidad. Material y métodos. Se ha realizado un estudio observacional retrospectivo unicéntrico en la Unidad de Cuidados Críticos Quirúrgicos (UCCQ) del Hospital General Universitario Dr. Balmis (HGUDB). Para el análisis estadístico se empleó el test de Wilcoxon y estadísticos descriptivos. Se consideró significativa un p < 0,05. Resultados. En nuestra población de estudio (n=32) se observa reducción significativa de la dosis de NA tras la administración de AVP (p<0,001). En los subgrupos con shock séptico (p=0,013) y hemorrágico (p=0.004) también se observa reducción significativa, mientras que en el grupo de shock vasopléjico post cirugía cardiaca con circulación extracorpórea (post-CEC) no se evidencia (p=0,062). Se observa un aumento significativo de las cifras de creatinina (p=0,023). El porcentaje de arritmias de novo es del 6,3%, el de complicaciones isquémicas 15,6% y la mortalidad del 59,4%. Conclusiones. El uso de AVP en la UCCQ del HGUDB logra reducir la dosis de perfusión de NA en pacientes con shock de características distributivas refractario al tratamiento convencional. El papel de la AVP respecto a la función renal en nuestra población aún está por determinar.
