ABSTRACT
ABSTRACT Objective: identify delirium and subsyndromal delirium in intensive care patients; age, hospitalization time, and mortality. Method: a retrospective, quantitative study conducted in the Intensive Care Unit, using the Richmond Agitation-Sedation Scale to evaluate sedation and the Intensive Care Delirium Screening Checklist for the identification of delirium, with the participation of 157 patients. For statistical analysis, the t-test and the Chi-square test was carried out. Results: the majority presented subsyndromal delirium (49.7%). Mortality was 21.7%. The relationship between delirium and its subsyndromal with hospitalization time was statistically significant for both (p=0.035 and p <0.001), while age was significant only in the subsyndromal delirium (p=0.009). Conclusion: the majority of the patients presented subsyndromal delirium. The length of hospital stay was statistically significant in delirium and subsyndroma delirium. Age was significant only in subsyndromal delirium. The mortality of patients with delirium was higher than the others.
RESUMEN Objetivo: identificar delirio y delirio subsindromáico en pacientes de terapia intensiva; relacionar con edad, tiempo de internación y demostrar la mortalidad. Método: el estudio retrospectivo, cuantitativo, realizado en Unidad de Terapia Intensiva, a través de la escala Richmond Agitation-Sedation Scale para evaluar la sedación y la escala Intensive Care Delirium Screening Checklist para identificación de delirio, con participación de 157 pacientes. Para el análisis estadístico, se aplicó la prueba t y el Qui-cuadrado. Resultados: la mayoría presentó delirio subsindromático (49,7%). La mortalidad fue del 21,7%. La relación entre el delirio y su subsíndrome con el tiempo de internación fue estadísticamente significativa para ambos (p = 0,035 y p <0,001), mientras que la edad fue significativa sólo en el subsindromático (p = 0,009). Conclusión: la mayoría de los pacientes presentó delirio subsindromático. El tiempo de internación fue estadísticamente significativo en el delirio y en el subsindromático. La edad fue significativa sólo en el subsindromático. La mortalidad del paciente con delirio fue mayor que los demás.

A idade foi significativa apenas no subsindromático. A mortalidade do paciente com delirium foi maior do que os demais.

Background: Sedatives and analgesic drugs give comfort and allow adequate respiratory support to critically ill patients in mechanical ventilation (MV). Its improper use may increase the duration of MV. Clinical guidelines suggest implementation of protocols, however this is seldom done in clinical practice. Aun: To compare in MV patients, nurse-applied guided by protocol administration of sedatives and analgesic drugs (protocol: group P) with the habitual practice using physicians criteria (control: group C). Material and methods: Inclusión criteria was the need of MV more than 48 h. The exclusión criteria were acute neurological diseases, hepatic cirrhosis, chronic renal failure and limitation of therapeutic efforts. Midazolam and fentanyl were used in both groups. The level of sedation was monitored with the Sedation Agitation Scale (SAS). In the P group, trained nurses applied algorithms to adjust the sedative doses according to a predefined SAS goal. Results: Forty patients were included, 22 aged 65±19 years in group P and 18 aged 54±21 years in group C. Apache II scores were 16±8 and 19±8 in each group. SAS score was more frequently evaluated within goal boundaries in group P than in group C (44 percent and 32 percent, respectively p =0.001). No differences in the proportion of patients with inadequate sedation were observed between treatment groups. Midazolam doses were lower in P than in C group (0.04 (0.02-0.07) and 0.06 (0.03-0.08) mg/kg/h respectively, p =0.005). Conclusions: The implementation of sedation protocol applied by nurses improved the quality of sedation and reduced the doses of Midazolam in mechanically ventilated patients.
