Abstract
Objective

To investigate the association between early blood pressure drop and worsening renal function (WRF) in ICU patients with liver failure and to evaluate their clinical outcomes.

Design

Retrospective observational study.

Setting

Intensive Care Medicine.

Patients

Patients admitted to the ICU for the first time during their first hospitalization; diagnosed with liver failure according to the International Classification of Diseases, Ninth and Tenth Revision codes; and aged ≥18 years were included. Patients with a peak systolic blood pressure (SBP) drop of <0 mmHg were excluded.

Intervention

We analyzed data of ICU patients with liver failure from the Medical Information Mart for Intensive Care IV version 2.2 database. Descriptive statistics, analysis of variance, Kruskal–Wallis test, and chi-square test were employed for analysis. Multivariate linear regression models were used to assess the determinants of blood pressure decline. Cox proportional hazards and generalized additive models were used to evaluate

Main variables of interest

The relationship between blood pressure decline, WRF, and 60-day in-hospital mortality were evaluated, along with subgroup analyses.

Results

Peak SBP drop was independently associated with higher risks of WRF (P < 0.001) and 60-day in-hospital mortality (P < 0.001), even after adjusting for potential confounders, including baseline SBP. The independent risk relationship observed between peak diastolic blood pressure, mean arterial pressure drop, and the occurrence of WRF and 60-day in-hospital mortality was similar.

Conclusions

In ICU patients with liver failure, a significant early drop in blood pressure was associated with a higher incidence of WRF, increased risk of 60-day in-hospital mortality, and poorer prognoses.

Resumen
Objetivo

Investigar la asociación entre los descensos precoces de la presión arterial y el empeoramiento de la función renal (EFR) en pacientes de la UCI con insuficiencia hepática y evaluar sus resultados clínicos.

Diseño

Estudio observacional retrospectivo.

Ámbito

Medicina Intensiva.

Pacientes

Se incluyeron los pacientes ingresados en la UCI por primera vez durante su primera hospitalización, diagnosticados de insuficiencia hepática según los códigos de la Clasificación Internacional de Enfermedades, Novena y Décima Revisión, y con una edad ≥18 años. Se excluyó a los pacientes con un descenso máximo de la PAS < 0 mmHg.

Intervención

Se analizaron los datos de los pacientes de la UCI con insuficiencia hepática de la base de datos Medical Information Mart for Intensive Care IV, versión 2.2. Para el análisis se emplearon estadísticas descriptivas, análisis de varianza, prueba de Kruskal–Wallis y prueba de ji-cuadrado. Se utilizaron modelos de regresión lineal multivariante para evaluar los factores determinantes del descenso de la presión arterial. Se utilizaron modelos de riesgos proporcionales de Cox y modelos aditivos generalizados para evaluar. Se utilizaron modelos de riesgos proporcionales de Cox y modelos aditivos generalizados para evaluar.

Variables de interés principales

Se evaluó la relación entre el descenso de la presión arterial, el EFR y la mortalidad intrahospitalaria a los 60 días, junto con análisis de subgrupos.

Resultados

El descenso máximo de la presión arterial sistólica (PAS) se asoció de forma independiente con mayores riesgos de EFR (p < 0,001) y mortalidad intrahospitalaria a los 60 días (p < 0,001), incluso tras ajustar por posibles factores de confusión, incluida la PAS basal. La relación de riesgo independiente observada entre la presión arterial diastólica máxima, la caída de la presión arterial media y la aparición de EFR y mortalidad hospitalaria a los 60 días fue similar.

Conclusiones

En los pacientes de la UCI con insuficiencia hepática, una caída precoz significativa de la presión arterial se asoció con una mayor incidencia de EFR, un mayor riesgo de mortalidad intrahospitalaria a los 60 días y un peor pronóstico.
