[Analysis of 4 sedation rating scales in the critical patient]. / Análisis de 4 escalas de valoración de la sedación en el paciente crítico.

BACKGROUND: This study aimed to verify the relationship between different Sedation Rating Scales (SRSs) for critical patients on mechanical ventilation and to know the relationship between the SRSs, clinical information and the dose of sedative and analgesia drugs (SAD). MATERIAL AND METHODS: A longitudinal, prospective analytic pilot study conducted in a Medical-Surgical Intensive Care Unit of a tertiary hospital from October-December 2006. The sample included patients who required administration of SAP and mechanical ventilation. The following biological parameters and scales were evaluated: patient's demographics, RAMSAY, Sedation Agitation Scale (SAS), Richmond Agitation Sedation Scale (RASS), Motor Activity Assessment Scale (MASS), SAD dose, mean blood pressure, cardiac rate, pupil diameter and respiratory frequency. Spearman coefficient of interrelation was used to compare the relationship between the different scales. RESULTS: A total of 2.412 measurements were made for each variable: SRS, clinical information and SAD dose in 30 patients with different diseases, 63 % males, age 52 +/- 19 years, APACHEII 24 +/- 8, SAPSII 44 +/- 16, with an ICU mortality UCI 34 %. Median and IQ range of stay in ICU 15.5 and 20 days, of mechanical ventilation 9 and 14 days, of SAD 6 and 5.5 days and of paralyzing drugs (PD) 2 and 5 days, respectively. Interrelation was detected between all the SRSs, with p < 0.0001. The relationship between SAS, RASS and MASS was direct, whereas these were related inversely to RAMSAY. No evidence of interrelation was found between the SRSs, the clinical information and the SAD doses. CONCLUSION: The RAMSAY scale that has not been validated in ICU patients has a strong interrelation with the other already validated SRSs. SRSs are subjective and do not correlate with the clinical information and the SAD doses, probably due to the sample's small size and heterogeneity.

Análisis de 4 escalas de valoración de la sedación en el paciente crítico / Analysis of 4 sedation rating scales in the critical patient

Introducción. Los objetivos del estudio fueron comprobar la correlación entre distintasescalas de valoración de la sedación (EVS) del paciente crítico con ventilación mecánica,así como conocer la asociación entre las EVS, datos clínicos y dosis de sedoanalgesia enperfusión (SAP).Material y métodos. Estudio analítico longitudinal prospectivo, realizado en una Unidadde Cuidados Intensivos Polivalente de un hospital terciario, desde octubre a diciembre de2006. La muestra incluyó a pacientes que precisaron administración de SAP y ventilaciónmecánica. Se valoraron: características de los pacientes, escala de Ramsay, escala desedación-agitación (SAS), escala de agitación-sedación de Richmond (RASS), escala deevaluación de la actividad motora (MAAS), dosis de SAP, tensión arterial media, frecuenciacardiaca, tamaño pupilar y frecuencia respiratoria. Se empleó el coeficiente de correlaciónde Spearman para valorar la relación entre las diferentes escalas.Resultados. Se realizaron 2.412 mediciones de cada variable: EVS, datos clínicos y dosisde SAP, en 30 pacientes con distintas patologías, 63% varones, edad 53 ± 19 años, APACHEII 23,8 ± 8,54, SAPS II 44,93 ± 16,52, mortalidad al alta en Unidad de Cuidados Intensivos(UCI) 34%. Mediana y rango intercuartílico de estancia en UCI 15,5 y 20 días, de ventilaciónmecánica 9 y 14 días, de SAP 6 y 5,5 días y de relajación en perfusión (RP) 2 y 5 días,respectivamente. Se detectó correlación entre todas las EVS, con una p < 0,0001. La relaciónentre SAS, RASS y MASS fue directa, mientras que estas se relacionaron inversamentecon el Ramsay. No se observó correlación entre las EVS, los datos clínicos y lasdosis de SAP.Conclusión. La escala de Ramsay, no validada, tiene una fuerte correlación con el restode las EVS estudiadas, ya validadas. Las EVS son subjetivas y no se correlacionan con losdatos clínicos y las dosis de SAP, probablemente por el reducido tamaño y heterogeneidadmuestral(AU)
