RESUMEN

This report describes how postoperative delirium in an elderly man during COVID-19 pandemic led to a serious event involving a central venous catheter. Delirium is a common cause of perioperative morbidity and mortality, and is characterised by an alteration in consciousness and perception and a reduced ability to focus, sustain or shift attention. The event was analysed by a multidisciplinary committee which developed a risk stratification delirium protocol in order to prevent similar events in the future.

RESUMEN

BACKGROUND: Little is known about the incidence of delirium and its subtypes in patients admitted to different departments of university hospitals in Latin America. OBJECTIVE: To determine the incidence of delirium and the frequency of its subtypes, as well as its associated factors, in patients admitted to different departments of a university hospital in Bogotá, Colombia. METHODS: A cohort of patients over 18 years of age admitted to the internal medicine (IM), geriatrics (GU), general surgery (GSU), orthopaedics (OU) and intensive care unit (ICU) services of a university hospital was followed up between January and June 2018. To detect the presence of delirium, we used the CAM (Confusion Assessment Method) and the CAM-ICU if the patient had decreased communication skills. The delirium subtype was characterised using the RASS (Richmond Agitation and Sedation Scale). Patients were assessed on their admission date and then every two days until discharged from the hospital. Those in whom delirium was identified were referred for specialised intra-institutional interdisciplinary management. RESULTS: A total of 531 patients admitted during the period were assessed. The overall incidence of delirium was 12% (95% CI, 0.3-14.8). They represented 31.8% of patients in the GU, 15.6% in the ICU, 8.7% in IM, 5.1% in the OU, and 3.9% in the GSU. The most frequent clinical display was the mixed subtype, at 60.9%, followed by the normoactive subtype (34.4%) and the hypoactive subtype (4.7%). The factors most associated with delirium were age (adjusted RR = 1.07; 95% CI, 1.05-1.09), the presence of four or more comorbidities (adjusted RR = 2.04; 95% CI, 1.31-3.20), and being a patient in the ICU (adjusted RR = 2.02; 95% CI, 1.22-3.35). CONCLUSIONS: The incidence of delirium is heterogeneous in the different departments of the university hospital. The highest incidence occurred in patients that were admitted to the GU. The mixed subtype was the most frequent one, and the main associated factors were age, the presence of four or more comorbidities, and being an ICU patient.

RESUMEN

INTRODUCTION AND OBJECTIVES: Delirium, recognized as a crucial prognostic factor in the cardiac intensive care unit (CICU), has evolved in response to the changing demographics among critically ill cardiac patients. This study aimed to create a predictive model for delirium for patients in the CICU. METHODS: This study included consecutive patients admitted to the CICU of the Samsung Medical Center. To assess the candidate variables for the model: we applied the following machine learning methods: random forest, extreme gradient boosting, partial least squares, and Plmnet-elastic.net. After selecting relevant variables, we performed a logistic regression analysis to derive the model formula. Internal validation was conducted using 100-repeated hold-out validation. RESULTS: We analyzed 2774 patients, 677 (24.4%) of whom developed delirium in the CICU. Machine learning-based models showed good predictive performance. Clinically significant and frequently important predictors were selected to construct a delirium prediction scoring model for CICU patients. The model included albumin level, international normalized ratio, blood urea nitrogen, white blood cell count, C-reactive protein level, age, heart rate, and mechanical ventilation. The model had an area under the receiver operating characteristics curve (AUROC) of 0.861 (95%CI, 0.843-0.879). Similar results were obtained in internal validation with 100-repeated cross-validation (AUROC, 0.854; 95%CI, 0.826-0.883). CONCLUSIONS: Using variables frequently ranked as highly important in four machine learning methods, we created a novel delirium prediction model. This model could serve as a useful and simple tool for risk stratification for the occurrence of delirium at the patient's bedside in the CICU.

RESUMEN

ABSTRACT This report aims to present an elderly woman with persistent delirium after hospitalization for lethargy secondary to hyponatremia. The diagnosis of pontine myelinolysis was made and there were no characteristic neurological manifestations such as pupillary changes or spastic tetraparesis. Hallucinations and personality changes were the clues to the diagnosis and should be considered an atypical manifestation of pontine myelinolysis.

RESUMO O objetivo deste relato é apresentar uma idosa que apresentou, após internação por letargia secundária à hiponatremia, delirium persistente depois da alta hospitalar. O diagnóstico de mielinólise pontina foi feito após a alta hospitalar e não houve manifestações neurológicas características, como alterações pupilares ou tetraparesia espástica. Alucinações e mudança de personalidade foram as pistas para o diagnóstico e devem ser consideradas como uma manifestação atípica de mielinólise pontina.

RESUMEN

ABSTRACT BACKGROUND AND OBJECTIVES: Bone fractures constitute a frequent cause of emergency care in the pediatric population. Opioid drugs are routinely used for analgesia during the hospitalization of children victims of trauma. Few studies have evaluated the importance of a multimodal approach to analgesia in this context. The aim of this study was to compare the analgesic effect and possible side effects of fentanyl compared to those of ketamine. METHODS: The study analyzed 50 children and adolescents, aged between 24 and 192 months, submitted to surgical treatment of upper limb fractures in a tertiary trauma care hospital. The participants were randomized into two groups: one that received Ketamine and the other Fentanyl. In the post-anesthetic recovery room (PARR), pain intensity and the occurrence of delirium were measured for a period of 30 minutes. The incidence of respiratory depression, nausea, vomiting and other side effects during the surgical procedure were assessed. RESULTS: The sample consisted mostly of male individuals (76.0%). The mean age of the participants was 90.1 months. The use of a low-flow oxygen cannula was necessary in 30.0% of the participants. The incidence of vomiting and laryngospasm was 2.0% among the participants, and 6.0% presented increased salivary secretion. The occurrence of pain, delirium and respiratory depression was not different between the two assessed groups, as well as the occurrence of nausea and laryngospasm. CONCLUSION: Ketamine is not an effective and safe option to opioids for analgesia in children undergoing surgical procedures to treat upper limb fractures.

RESUMO JUSTIFICATIVA E OBJETIVOS: As fraturas ósseas constituem causa frequente de atendimento de emergência na população pediátrica. Fármacos opioides são rotineiramente utilizados para analgesia durante a hospitalização de crianças vítimas de trauma. Poucos estudos avaliaram a importância de uma abordagem multimodal para analgesia nesse contexto. O objetivo deste estudo foi comparar o efeito analgésico e possíveis efeitos adversos do fentanil em relação aos da cetamina. MÉTODOS: Foram analisados 50 crianças e adolescentes, com idade entre 24 e 192 meses, submetidos ao tratamento cirúrgico das fraturas de membros superiores em um hospital terciário de atendimento ao trauma. Os participantes foram aleatorizados em dois grupos: um recebeu cetamina e outro fentanil. Na sala de recuperação pós-anestésica (SRPA), a intensidade da dor e a ocorrência de delirium foram mensuradas por um período de 30 minutos. A incidência de depressão respiratória, náuseas, vômitos e outros efeitos adversos durante o procedimento cirúrgico foram avaliados. RESULTADOS: A amostra foi composta, em sua maioria, por indivíduos do sexo masculino (76,0%). A média de idade dos participantes foi de 90,1 meses. O uso de cânula de oxigênio de baixo fluxo foi necessário em 30,0% dos participantes. A incidência de vômitos e laringoespasmo foi de 2,0% entre os participantes, sendo que 6,0% apresentaram aumento da secreção salivar. A ocorrência de dor, delirium e depressão respiratória não foi diferente entre os dois grupos avaliados, assim como a ocorrência de náuseas e laringoespasmo. CONCLUSAO: Acetamina não se mostrou uma opção eficaz e segura aos opioides para analgesia em crianças submetidas a procedimentos cirúrgicos para tratamento de fraturas de membros superiores.

Introduction: Delirium is a mental disorder that frequently affects critically-ill patients and causes increased days of hospitalization. It can be prevented through timely nursing interventions; however, such are applied in a restricted way in intensive care units in Peru. Objective: To evaluate the effectiveness of nursing intervention in the prevention of delirium in critically-ill patients. Methods: A quasiexperimental study was conducted with two groups in the intensive care unit of Hospital María Auxiliadora, of Lima, Peru, in 2021. The population was 67 patients, 33 in the experimental group and 34 in the control group, who met the inclusion criteria. Two were excluded from the first group due to over-added complications; 31 remained. The intervention was organized in four sections. The following instruments were applied: Confusion assessment method for diagnosing delirium in ICU patients (CAM-ICU) and a checklist, valid and reliable. To determine effectiveness, pre- and post-nursing intervention assessment was performed. The data were processed with the software IBM SPSS (version 23). Descriptive statistics and Pearson's chi-square method were used for the analysis. Results: In the experimental group, 3.20 percent of the patients presented delirium after the intervention and 23.50 percent did so in the control group. Bivariate analysis with chi-squared statistical test evidenced p = 0.02, a significant result. Conclusions: The nursing intervention was effective, as it mostly prevented delirium in critically-ill patients(AU)

RESUMEN

Abstract Objective: to detect the incidence of postoperative delirium in critically ill patients admitted to a surgical intensive care unit and to evaluate the predisposing and precipitating factors associated with postoperative delirium in critically ill patients admitted to a surgical intensive care unit. Method: this is a prospective cohort study of 157 critically ill surgical patients. Fisher's exact test and Chi-square test were used for the association between factors and the occurrence of delirium, the Wilcoxon test for numerical variables, and the logistic regression model for the analysis of predisposing and precipitating factors. Results: the incidence of delirium was 28% (n=44). Age was a significant predisposing factor (p=0.001), followed by the length of surgery (p<0.001), blood transfusion (p=0.043), administration of crystalloids (p=0.008), and anti-inflammatory drugs (p=0.037), which were the precipitating factors identified. The best-adjusted models were: age, length of surgery, non-administration of anti-emetics, use of sufentanil, and blood transfusion. Conclusion: delirium is a frequent condition in critically ill adults undergoing surgery and the existence of precipitating and predisposing factors is relevant to the outcome, with the anesthetic-surgical procedure as the catalyst event.

RESUMEN

El concepto de delirio ha sido tematizado ampliamente por la psiquiatría feno-menológica a lo largo del siglo XX. Por el contrario, su relación con la verdad aparece en su desarrollo filosófico un tanto volátil. Ya Jaspers advirtió de la futilidad de esta a la hora de definir el delirio. En la práctica, en cambio, sí que adquiere cierta significación y efectividad a la hora de un diagnóstico. En el presente ensayo se trata de emprender una exploración de la relación entre el delirio y la verdad a la luz de los principios filosóficos del Nuevo Realismo representado por Markus Gabriel y del perspectivismo orteguiano. Se intentará concluir que la relación entre ambos conceptos se decidirá en su valor para la vida. (AU)

The concept of delusion was widely discussed in the Psychiatry and Pheno-menology of the 20th century. In contrast, its relation to truth in its philosophical deve-lopment appears to be quite elusive. Jaspers warned about its futility in the definition of delusion. Nevertheless, from a practical perspective seems to play a meaningful, efficient role as a diagnostic indication. We pursue an investigation about delusion and truth in the light of Markus Gabriel’s New Realism and Ortega y Gasset’s Perspecti-vism. Finally, their relation will be decided in its value for life.

En el sistema operativo se establecieron dos indicadores empíricos: el Confusion Assessment Method for Intensive Care Units y el historial demográfico/clínico de las personas mayores. Posteriormente, se produjeron dos declaraciones transformacionales, cuatro hipótesis y el modelo de cuidado representado en figura. Conclusión: la microteoría producida prescribe cuidados en la prevención del delirium en personas mayores en cuidados intensivos, por un constructo de interés para la enfermería, y permite intervenciones en el desarrollo de instrumentos que guían la actuación de la enfermería.

Objective: to describe a microtheory for nursing care in the prevention of delirium in older adult in the intensive care unit. Method: prescriptive theoretical research, based on substruction. Roy's Adaptation Model constructs were deduced and data from the phenomenon of nursing care in the prevention of delirium in older adult in intensive care were induced, based on an integrative literature review. Results: the microtheory has a theoretical and operational system and a model of care. In the theoretical system, Roy's focal and contextual stimulus constructs were used. From them, the concepts of focal and contextual care and the variable adaptive response to prevention were elaborated. From the relational statements, four axioms, two postulates, eight propositions and an epistemic assumption were elaborated. Two empirical indicators were established in the operating system: the Confusion Assessment Method for Intensive Care Units and the demographic/clinical history of the older adult. Subsequently, two transformational statements, four hypotheses and the model of care represented in figure were produced. Conclusion: the microtheory produced prescribes care in the prevention of delirium in older adult in intensive care, through a construct of interest to nursing, and allows interceptions for the development of instruments that guide nursing activities.

RESUMEN

Introducción. La debilidad adquirida en las unidades de cuidados intensivos es una complicación frecuente de los pacientes con enfermedades críticas, que puede tener un impacto negativo en su pronóstico a corto y a largo plazo. Objetivos. Evaluar si la utilización de un protocolo multicomponente, que incluye movilidad activa temprana, manejo efectivo del dolor, reducción de la sedación, medidas no farmacológicas para prevenir el delirium, estimulación cognitiva y apoyo familiar, puede disminuir la incidencia de debilidad adquirida en las unidades de cuidados intensivos al momento del egreso del paciente. Materiales y métodos. Se trata de un ensayo clínico, no aleatorizado, en dos unidades de cuidados intensivos mixtas de un hospital de tercer nivel. Los participantes fueron pacientes mayores de 14 años con ventilación mecánica invasiva por más de 48 horas. Se aplicó como intervención un protocolo multicomponente y como control se utilizó el cuidado usual o estándar. Resultados. Ingresaron 188 pacientes al estudio, 82 al grupo de intervención y 106 al grupo control. La tasa de debilidad adquirida en las unidades de cuidados intensivos al egreso de la unidad fue significativamente menor en el grupo de intervención (41,3 % versus 78,9 %, p<0,00001). La mediana del puntaje de movilidad al momento del alta de la unidad de cuidados intensivos fue mayor en el grupo de intervención (3,5 versus 2, p<0,0138). No se encontraron diferencias estadísticamente significativas en las medianas de días libres de respiración mecánica asistida, ni de unidad de cuidados intensivos al día 28, tampoco en la tasa de mortalidad general al egreso del hospital (18 versus 15 días, p<0,49; 18,2 % versus 27,3 %, p<0,167). Conclusiones. Un protocolo multicomponente que incluía movilidad activa temprana tuvo un impacto significativo en la reducción de la debilidad adquirida en las unidades de cuidados intensivos al egreso en comparación con el cuidado estándar.

Introduction. Intensive care unit-acquired weakness is a frequent complication that affects the prognosis of critical illness during hospital stay and after hospital discharge. Objectives. To determine if a multicomponent protocol of early active mobility involving adequate pain control, non-sedation, non-pharmacologic delirium prevention, cognitive stimulation, and family support, reduces intensive care unit-acquired weakness at the moment of discharge. Materials and methods. We carried out a non-randomized clinical trial in two mixed intensive care units in a high-complexity hospital, including patients over 14 years old with invasive mechanical ventilation for more than 48 hours. We compared the intervention -the multicomponent protocol- during intensive care hospitalization versus the standard care. Results. We analyzed 82 patients in the intervention group and 106 in the control group. Muscle weakness acquired in the intensive care unit at the moment of discharge was less frequent in the intervention group (41.3% versus 78.9%, p<0.00001). The mobility score at intensive unit care discharge was better in the intervention group (median = 3.5 versus 2, p < 0.0138). There were no statistically significant differences in the invasive mechanical ventilation-free days at day 28 (18 versus 15 days, p<0.49), and neither in the mortality (18.2 versus 27.3%, p<0.167). Conclusion. A multi-component protocol of early active mobility significantly reduces intensive care unit-acquired muscle weakness at the moment of discharge.

RESUMEN

Se denomina agitación o delirio postoperatorio al estado de alteración de la conciencia que se presenta tras la cirugía y que afecta especialmente al paciente pediátrico. Presenta una incidencia nada despreciable, alcanzando el 80% de los casos en determinados estudios. Frecuentemente es confundido con otras entidades clínicas, por lo que se ha validado una escala que facilita su diagnóstico. Entre sus factores de riesgo destaca la edad inferior a 5años, la presencia de dolor tras la cirugía y, especialmente, la ansiedad intensa preoperatoria. El delirio postoperatorio se presenta como un evento adverso tras una intervención quirúrgica y tiene influencia en la seguridad del paciente, aumentando considerablemente su comorbilidad. Es fundamental reconocer la entidad, así como sus factores de riesgo, para aplicar medidas de prevención eficaces que disminuyan su incidencia y su intensidad cuando esta se presenta. (AU)

The state of altered consciousness that occurs after surgery, particularly in paediatric patients, is called emergence delirium or postoperative agitation, and some studies report an incidence of up to 80%. This high incidence is due to clinicians frequently mistaking this phenomenon for other clinical entities, and to avoid this confusion a scale has been validated to facilitate diagnosis. The main risk factors include age under 5years, postoperative pain, and particularly, intense preoperative anxiety. Paediatric emergence delirium is an adverse postoperative event that significantly increases comorbidity. It is essential to recognize this entity and its risk factors in order to apply effective preventive measures to reduce both incidence and intensity. (AU)

RESUMEN

Fundamentos: El síndrome confusional agudo (SCA) es una de las complicaciones con mayor morbimortalidad en las unidades de hospitalización, pero es una situación reversible si se detecta a tiempo, representando un claro desafío para la enfermería. Los objetivos de este estudio fueron valorar previa y posteriormente las intervenciones realizadas por las enfermeras para la identificación y la adopción de las medidas preventivas no farmacológicas aplicadas en el síndrome confusional agudo, así como relacionarlas con los años de experiencia profesional y la formación recibida. Métodos: Se realizó un estudio cuasi experimental, prospectivo y analítico a través de cuestionario estructurado autoadministrado pre-post intervención (extraído de la JBI PACES program-Practical Application of Clinical Evidence System) sobre la identificación y las medidas preventivas aplicadas en el SCA. Se distribuyeron un total de quinientos veinte cuestionarios (valoración pre y post) a enfermeras del servicio de Urgencias y la unidad de medicina interna del Hospital Universitario Miguel Servet de Zaragoza (Aragón, España) de enero de 2021 a abril de 2022. El análisis estadístico se realizó con el programaJamovi® 2.3.13. Resultados: Se recibieron ciento ochenta cuestionarios cumplimentados correctamente (noventa y cuatro pre y ochenta y seis post). Para el 100%, el SCA supuso una carga de trabajo extra y se hallaron diferencias estadísticamente significativas entre la capacidad de manejo de SCA con los años de experiencia profesional (p=<0,028). El 97,2% de las enfermeras aplicaron intervenciones no farmacológicas. Conclusiones: A pesar de percibirse como una carga extra en el trabajo diario, las enfermeras realizan prevenciones no farmacológicas para el manejo del SCA. Es necesario mejorar la formación para proporcionar estrategias de orientación.(AU)

Background: Acute confusional syndrome (ACS) is one of the complications with the highest morbidity and mortality in hospitalization units, but it is a reversible situation if detected early, representing a clear challenge for nursing. The objectives of this studywere to assess the interventions carried out by nurses for the identification and non-pharmacological preventive measures applied inacute confusional syndrome and relate them to the years of professional experience and training received.Methods: A quasi-experimental, prospective and analytical study was carried out through a selfdministered structured questionnaire pre-post intervention (extracted from theJBI PACES program-Practical Application of Clinical Evidence System) on the identificationand preventive measures applied in ACS. A total of 520 questionnaires (pre and post assessment) were distributed to nurses from theemergency department and the internal medicine unit of the Miguel Servet University Hospital in Zaragoza (Aragón, Spain) from January2021 to April 2022. Statistical analysis carried out with the programJamovi®2.3.13.Results: 180 correctly completed questionnaires (94 pre and 86 post) were received. For 100%, the ACS supposed an extra workload and significant differences were found between the ability to manage ACS with the years of professional experience (p=<0.028).97.2% of the nurses applied non-pharmacological interventions.Conclusions: Despite being perceived as an extra burden in daily work, nurses perform nonpharmacological prevention for themanagement of ACS. It is necessary to improve training to provide guidance strategies.(AU)

RESUMEN

Antecedentes y objetivo Las características y la evolución de los pacientes con confusional subsindromático (CSS) en la internación aún continúa en discusión. El objetivo fue describir la incidencia de síndrome confusional agudo (SCA) y CSS en terapia intensiva (UTI), analizar su asociación con la presencia de factores de riesgo y explorar diferencias en la evolución hospitalaria y a los tres meses del alta. Pacientes y métodos Estudio prospectivo con seguimiento telefónico tres meses luego del alta. Se aplicó el CAM-ICU para definir tres grupos: sin delirio (de referencia), CSS y SCA. Resultados En 270 pacientes, el 22,96% presentaron SCA y el 17,03%, CSS. Factores relacionados con mayor riesgo de SCA: deterioro cognitivo (p=0,000), edad ≥75años (p=0,019), motivo de ingreso neurológico (p=0,003), shock (p=0,043), escaras (p=0,010), polifarmacia (0,017), ARM (p=0,001) y reposo digestivo (p=0,028); con mayor riesgo de CSS: baja escolaridad (p=0,014), Charlson >5 (p=0,028), AIVD <8 (p=0,001), alimentación enteral (p=0,000) y motivo de ingreso no cardiovascular (p=0,019). La mortalidad global fue del 6% en el grupo sin delirio, del 8% en CSS (p=0,516) y del 30% en SCA (p=0,000). La mediana de internación en UTI fue de 2días (rango 1-2) en el grupo sin delirio, 3 (2-4) días en CSS (p=0,0001) y 3 (2-7) días en SCA (p=0,0001). A los tres meses del alta, las AIVD estaban conservadas en el 50% del grupo sin delirio, en el 30% de CSS (p=0,026) y en el 26% de SCA (p=0,005). Conclusiones El CSS presentó un pronóstico intermedio entre el grupo sin delirio y el SCA. Se aconseja su diagnóstico para mejor clasificación de riesgo (AU)

Background and objective The characteristics and outcomes of patients with subsyndromal delirium (SSD) at hospitalization are still under discussion. The objectives were to describe the incidence of delirium and SSD in the intensive care unit (ICU), to analyze the association with risk factors and to explore outcomes of delirium and SSD at hospitalization and three months after discharge. Patients and methods A prospective study, with telephone follow-up three months after discharge. The study included 270 patients over one year. Delirium and SSD were assessed with the CAM-ICU. Results 22.96% developed delirium and 17.03% SSD. The main risk factors associated with the development of delirium were cognitive impairment (P=.000), age ≥75years (P=.019), neurological admission (P=.003), shock (P=.043), bedsores (P=.010), polypharmacy (P=.017), ARM (P=.001) and fast (P=.028), and with the development of SSD were low schooling (P=.014), Charlson >5 (P=.028), AIVD <8 (P=.001), enteral feeding (P=.000) and non-cardiovascular admission (P=.019). Overall mortality was 6% in the group without delirium (reference), 8% in SSD (P=.516) and 30% in delirium (P=.000). Median ICU length of stay was 2 (IQR, 1-2) days in the group without delirium, 3 (IQR, 2-4) days in SSD (P=.0001), and 3 (IQR, 2-7) days in delirium group (P=.0001). Three months after discharge, instrumental ADL were preserved in 50% of the group without delirium, 30% of SSD (P=.026) and 26% of delirium (P=.005). Conclusions The SSD group presented an intermediate prognosis between no delirium and delirium groups. It is advisable to promote its diagnosis for better risk classification (AU)

RESUMEN

RESUMEN Objetivo: Identificar los factores asociados al delirio de emergencia en niños en la Unidad de Recuperación Posanestésica de un Instituto Especializado en Salud Pediátrica del Perú. Métodos: Se realizó un estudio transversal en niños de 2 a 6 años, clasificación del estado físico I y II, en procedimientos electivos bajo anestesia entre septiembre y diciembre 2022. La variable principal fue la presencia de delirio de emergencia evaluada con la escala Pediatric Anesthesia Emergence Delirium mayor o igual a 10 puntos. Para identificar los factores asociados con el delirio, se aplicó el modelo de regresión de Poisson y se consideró significativo un valor p < 0,05. Resultados: De los 150 niños, se encontró que la incidencia de delirio de emergencia se presentó en el 10,6%. De ellos, el 81,4% fueron menores de 5 años, el dolor se asoció significativamente en el 37,5% con RP = 3,63, IC95% [1,20, 10,1] y se observó que el 68,8% necesitó cuidados paliativos. Conclusiones: El dolor se asoció con el delirio de emergencia posanestésico en niños. La prevención y el tratamiento del delirio de emergencia deben centrarse en el control del dolor posoperatorio y en la vigilancia cuidadosa de los pacientes después de la cirugía.

ABSTRACT Objective: Identify associated factors with emergence delirium in children in the Post-Anesthetic Recovery Unit of a Pediatric Health Specialized Institute in Peru. Methods: A cross-sectional study was carried out in children from 2 to 6 years old, physical status classification I and II, in elective procedures under anesthesia. The main variable was the presence of emergence delirium evaluated with the Pediatric Anesthesia Emergence Delirium scale greater than or equal to 10 points. To identify the factors associated with delirium, the Poisson regression model was applied and a p value < 0.05 was considered significant. Results: Of the 150 children, it was found that the incidence of emergence delirium occurred in 10.6%. Of these, 81.4% were under 5 years of age, pain was significantly associated in 37.5% with PR = 3.63, 95%CI [1.20, 10.1] and it was observed that 68, 8% required palliative care. Conclusion: Pain was associated with delirium of postanesthetic emergence in children. Prevention and treatment of emergence delirium should focus on postoperative pain control and careful monitoring of patients after surgery.

RESUMEN

Emergence delirium or postoperative agitation is the name given to the state of altered consciousness that occurs after surgery and especially affects pediatric patients. Its incidence is not negligible, reaching 80% of cases in certain studies. It is frequently confused with other clinical entities, for which reason a scale has been validated to facilitate its diagnosis. Risk factors include age under 5 years, the presence of pain after surgery and especially intense preoperative anxiety. Pediatric emergence delirium presents as an adverse event after surgery and influences patient safety by significantly increasing patient comorbidity. It is essential to recognize the entity, as well as its risk factors, in order to apply effective preventive measures to reduce its incidence and intensity when it occurs.

RESUMEN

This group is a product of the collaboration agreement signed by SOMIAMA (Sociedad de Medicina Intensiva de Madrid) and SAR MADRID (Sociedad de Anestesiología, Reanimación y Terapéutica del Dolor de Madrid) under which the organisations agreed to create joint working groups to improve critical patient care. Pain, discomfort, agitation, and delirium cause suffering, delay discharge, and can lead to serious complications in patients admitted to medical and surgical critical care units and post-anaesthesia care units. The main objectives in this type of unit include: Ensuring the comfort of patients suffering or recovering from a critical illness.Avoiding complications associated with the measures, particularly pharmacological, taken to ensure that comfort.

RESUMEN

ABSTRACT Objective: To translate and cross-culturally adapt the Cornell Assessment of Pediatric Delirium anchor points from English to Brazilian Portuguese. Methods: For the translation and cross-cultural adaptation of the anchor points, all steps recommended internationally were followed after authorization for use by the lead author. The stages were as follows: translation of the original version into Portuguese by two bilingual translators who were native speakers of the target language, synthesis of the versions, reverse translation by two translators who were native speakers of the source language, review and synthesis of the back-translation, review by a committee of experts and preparation of the final version. Results: The translation and cross-cultural adaptation of the anchor points was conducted in accordance with recommendations. The linguistic and semantic issues that arose were discussed by a committee of judges, with 91.8% agreement, as determined using a Likert scale, after changes by consensus. After reanalysis by the authors, there were no changes, resulting in the final version, which was easy to understand and administer. Conclusion: The translation and cross-cultural adaptation of the anchor points of the Cornell Assessment of Pediatric Delirium scale into Portuguese spoken in Brazil were successful, maintaining the linguistic and semantic properties of the original instrument. The table of anchor points is easy to understand and will be helpful during the assessment of children younger than 24 months using the Cornell Assessment of Pediatric Delirium scale.
