When the "U" is not Inverted: Trajectories of Expressed Emotional Arousal Predict Relationship Satisfaction.

Maladaptive emotional reactivity and dysfunctional communication during couple conflict are both destructive to couple functioning, and observational research has elucidated how conflict escalates. However, much of the evidence is based on measures that combine content (i.e., what was said) and the emotion with which it was said, which are then examined using sequential analyses. Despite the general presumptions about underlying emotional reactivity and escalation in negative emotions as part of relationship distress and deterioration, little empirical data are available that directly examine these continuous shifts in emotions. The current study examined concurrent and longitudinal associations between relationship satisfaction and trajectories of change in vocally expressed emotional arousal during couple conflict in 62 couples who participated in a relationship education program. Contrary to expectations and patterns found in distressed couples, trajectories followed a U-shape rather than an inverted U-shape curve, with steeper and more persistent decreases in emotional arousal predicting more stable relationship satisfaction over time. In addition, there were within-couple effects. These results suggest that early signs for relationship deterioration may be less in the form of overt escalation as would be seen in distressed couples. Instead, couples who subsequently deteriorate more are less effective in calming emotional arousal. They also are less able to remain at lower emotional arousal. It is possible that the more pronounced escalation toward the end of the conversation in more at-risk couples is a precursor of the greater escalation patterns seen in distressed couples; this should be examined empirically. Limitations and implications are discussed.

La reactividad emocional desadaptativa y la comunicación disfuncional durante el conflicto de pareja son destructivas para el funcionamiento de la pareja, y la investigación observacional ha dilucidado cómo escala el conflicto. Sin embargo, gran parte de la evidencia está basada en mediciones que combinan el contenido (p. ej.: lo que se dijo) y la emoción con la que se dijo, que luego se analizan usando análisis secuenciales. A pesar de las presunciones generales acerca de la reactividad emocional subyacente y la escalada de las emociones negativas como parte del distrés y el deterioro de la relación, existen pocos datos empíricos que analicen directamente estos cambios continuos en las emociones. El presente estudio analizó las asociaciones simultáneas y longitudinales entre la satisfacción con la relación y las trayectorias de cambio en la agitación emocional expresada vocalmente durante el conflicto de pareja en 62 parejas que participaron en un programa de capacitación en relaciones. Contrariamente a las expectativas y los patrones hallados en las parejas problemáticas, las trayectorias siguieron una forma de U en lugar de una curva con forma de U invertida, con disminuciones más pronunciadas y más constantes de la agitación emocional que predicen una satisfacción más estable con la relación en el transcurso del tiempo. Además, hubo efectos dentro de la pareja. Estos resultados sugieren que las primeras señales de deterioro de la relación pueden ser menores en forma de escalada abierta de lo que se vería en las parejas problemáticas. En cambio, las parejas que posteriormente se deterioran más son menos eficaces a la hora de calmar la agitación emocional. También son menos capaces de permanecer en una agitación emocional más baja. Es posible que la escalada más pronunciada hacia el final de la conversación en las parejas con mayor riesgo sea una precursora de los patrones de mayor escalada observados en las parejas problemáticas; esto debería analizarse empíricamente. Se debaten las limitaciones y las consecuencias.

[Development of a liquid fermentation system and encystment for a nitrogen-fixing bacterium strain having biofertilizer potential]. / Desarrollo de un sistema de fermentación líquida y de enquistamiento para una bacteria fijadora de nitrógeno con potencial como biofertilizante.

The indiscriminate use of chemical fertilizers has contributed to the deterioration of the biological, physical and chemical properties of the soil, resulting in the loss of its productive capacity. For this reason, the use of biofertilizers has emerged as a technological alternative. The objective of this research was to develop a suitable liquid fermentation system and encystment for the multiplication of Azotobacter chroococcum AC1 strain, a bacterium employed in a biofertilizer formulation produced at present by CARPOICA, Colombia. Sequential statistical designs were used to determine the conditions in the fermentation system. The interaction between agitation, aeration and pH was evaluated on the viable biomass (CFU/ml) of AC1. In addition, the encystment ability of the strain was evaluated using two encystment agents and the potential plant growth-promoting rhizobacteria (PGPR) activity was assessed by different techniques, such as nitrogen fixation by ARA, phosphate solubilization by the phospho-molybdenum-blue reaction and indolic compound production by colorimetric reaction using the Salkowski reagent. Results showed significant effects (p<0.05) on the viable biomass in the three conditions (pH, aeration and agitation) tested individually, in one dual interaction and one tripartite interaction, were demonstrated to have a positive effect on the response variable aeration and agitation. The addition of the two encystment agents evaluated, AE01 and AE02, demonstrated the ability of AC1 to form cysts under stress conditions. Likewise, fermentation and encystment conditions did not affect the biological activities tested.

Control of agitation and aeration rates in the production of surfactin in foam overflowing fed-batch culture with industrial fermentation.

Bacillus amyloliquefaciens fmb50 produces a high yield of surfactin, a lipopeptide-type biosurfactant that has been widely studied and has potential applications in many fields. A foam overflowing culture has been successfully used in the combined production-enrichment fermentation of surfactin. In this study, the agitation and aeration rates were found to have relationships with foam formation and surfactin enrichment. A maximum surfactin concentration of 4.7g/l of foam was obtained after 21h of culture with an agitation rate of 150rpm and an aeration rate of 1vvm in fed-batch culture. By controlling the foam overflow rate (fout) of a fed-batch culture, surfactin concentration in the foam was continuously maintained above 4g/l.

Clinical practice guidelines for evidence-based management of sedoanalgesia in critically ill adult patients.

INTRODUCTION: Optimal management of sedation, analgesia and delirium offers comfort and security for the critical care patient, allows support measures to be applied more easily and enables an integral approach of medical care, at the same time that lowers the incidence of complications, wich translates in better patient outcomes. OBJECTIVE: To update the Guía de práctica clínica basada en la evidencia para el manejo de la sedoanalgesia en el paciente adulto críticamente enfermo published in Medicina Intensiva in 2007, and give recommendations for the management of sedation, analgesia, and delirium. METHODOLOGY: A group of 21 intensivists from 9 countries of the Federación Panamericana e Ibérica de Sociedades de Medicina Crítica y Terapia Intensiva, 3 of them also specialists in clinical epidemiology and methodology, gathered for the development of guidelines. Assessment of evidence quality and recommendations were made based on the Grading of Recommendations Assessment, Development and Evaluation system. Strength of recommendations was classified as 1=strong, or 2=weak, and quality of evidence as A=high, B=moderate, or C=low. Two authors searched the following databases: MEDLINE through PUBMED, The Cochrane Library and Literatura Latinoamericana y del Caribe en Ciencias de la Salud and retrieved pertinent information. Members assigned to the 11 sections of the guidelines, based on the literature review, formulated the recommendations, that were discussed in plenary sessions. Only those recommendations that achieved more than 80% of consensus were approved for the final document. The Colombian Association of Critical Medicine and Intensive Care (AMCI) supported the elaboration of this guidelines. RESULTS: Four hundred sixty-seven articles were included for review. An increase in number and quality of publications was observed. This allowed to generate 64 strong recommendations with high and moderate quality of evidence in contrast to the 28 recommendations of the previous edition. CONCLUSIONS: This Guidelines contains recommendations and suggestions based on the best evidence available for the management of sedation, analgesia and delirium of the critically ill patient, including a bundle of strategies that serves this purpose. We highlight the assessment of pain and agitation/sedation through validated scales, the use of opioids initially to apropiate analgesic control, associated with multimodal strategies in order to reduce opioide consumption; to promote the lowest level of sedation necessary avoiding over-sedation. Also, in case of the need of sedatives, choose the most appropiate for the patient needs, avoiding the use of benzodiazepines and identify risk factors for delirium, in order to prevent its occurrence, diagnose delirium and treat it with the most suitable pharmacological agent, whether it is haloperidol, atypical antipsychotics or dexmedetomidine, once again, avoiding the use of benzodiazepines and decreasing the use of opioids.

Postoperative agitation or delirium in paediatric patients. What we know and how to avoid it.

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.

The effect of pre-operative sleep quality on post-operative pain and emergence agitation: prospective and cohort study.

OBJECTIVE: Our study aimed to investigate the effect of pre-operative sleep quality on post-operative pain and emergence agitation. MATERIALS AND METHODS: Our study was performed 80 patients with American Society of Anesthesiologists I-II and 18-65 years of age. The patients were divided into poor (Group A, n = 40) and good sleep quality (Group B, n = 40). All patients were operated on under standard general anesthesia. The emergence agitation and pain status of all groups were evaluated in the recovery room and post-operative period. RESULTS: There was no significant difference between the groups regarding demographic data. Post-operative numeric rating scale scores and analgesic consumption were significantly higher in Group A than in Group B (p < 0.05). There was no significant difference between the groups regarding post-operative emergence agitation and extubation quality (p > 0.05). CONCLUSION: In our study, poor pre-operative sleep quality increases post-operative pain and analgesic consumption; however, emergence agitation is not associated with sleep quality in the pre-operative period.

OBJETIVO: Nuestro estudio tuvo como objetivo investigar el efecto de la calidad del sueño preoperatorio sobre el dolor posoperatorio y la agitación de emergencia. MATERIALES Y MÉTODOS: Nuestro estudio se realizó en 80 pacientes con ASA I-II y de 18 a 65 años de edad. Los pacientes se dividieron en mala (grupo A, n = 40) y buena calidad del sueño (grupo B, n = 40). Todos los pacientes fueron operados bajo anestesia general estándar. La agitación de emergencia y el estado del dolor de todos los grupos se evaluaron en la sala de recuperación y en el período postoperatorio. RESULTADOS: No hubo diferencia significativa entre los grupos con respecto a los datos demográficos. Las puntuaciones NRS postoperatorias y el consumo de analgésicos fueron significativamente más altos en el Grupo A que en el Grupo B (p < 0.05). No hubo diferencia significativa entre los grupos con respecto a la agitación de emergencia postoperatoria y la calidad de la extubación (p > 0.05). CONCLUSIÓN: En nuestro estudio, la mala calidad del sueño preoperatorio aumenta el dolor posoperatorio y el consumo de analgésicos; sin embargo, la agitación de emergencia no se asocia con la calidad del sueño en el período preoperatorio.

Scales in pain control in patients post-ictus with aphasia: A comparative study.

The assessment of pain and its control is a key point in the care received by patients during their hospital stay, with the nurse being an essential figure, especially in stroke patients with secondary aphasia, which makes it difficult to verbalise pain. The aim of this study was to find out whether the use of a specific pain control scale and the more precise administration of analgesic treatment has a positive impact on indicators such as average stay length, dependence degree and agitation episodes. By means of a longitudinal randomised group design study, within a two-week period, we compared the management and recording of pain using a Pain Indicator Behaviour Scale (N = 41) and a Verbal Numerical Scale or Visual Analogue Scale (N = 39), in patients with language impairment after suffering a stroke who were admitted to the Stroke Unit of the Neurology Department of the Hospital Clínic de Barcelona. The results obtained, despite being in line with what was conjectured, are not statistically significant. However, some statistical models have shown the usefulness of some factors (level of training, nurses experience, previous episodes of stroke, among others) in the prediction of a better evolution, with a predictive capacity between 20-37%, which justifies the necessity of further studies and reinforces the role of the variables studied in the care of this type of patient.

The use of mechanical restraint in critical care units: Characterisation, application standards and related factors. Results of a multicentre study.

OBJECTIVES: To describe and characterise the use of mechanical restraint (MR) in critical care units (CCU) in terms of frequency and quality of application and to study its relationship with pain/agitation-sedation/delirium, nurse:patient ratio and institutional involvement. METHOD: Multicentre observational study conducted in 17 CCUs between February and May 2016. The observation time per CCU was 96 h. The main variables were the prevalence of restraint, the degree of adherence to MR recommendations, pain/agitation-sedation/delirium monitoring and institutional involvement (protocols and training of professionals). RESULTS: A total of 1070 patients were included. The overall prevalence of restraint was 19.11%, in patients with endotracheal tube (ETT) 42.10% and in patients without ETT or artificial airway it was 13.92%. Adherence rates between 0% and 40% were obtained for recommendations related to non-pharmacological management and between 0% and 100% for those related to monitoring of ethical-legal aspects. The lower prevalence of restraint was correlated with adequate pain monitoring in non-communicative patients (P < .001) and with the provision of training for professionals (P = .020). An inverse correlation was found between the quality of the use of MR and its prevalence, both in the general group of patients admitted to CCU (r = -.431) and in the subgroup of patients with ETT (r = -.521). CONCLUSIONS: Restraint is especially frequently used in patients with ETT/artificial airway, but is also used in other patients who may not meet the use profile. There is wide room for improvement in non-pharmacological alternatives to the use of MC, ethical and legal vigilance, and institutional involvement. Better interpretation of patient behaviour with validated tools may help limit use of MR.

Evidence-based clinical practice guidelines for the management of sedoanalgesia and delirium in critically ill adult patients. / Guías de práctica clínica basadas en la evidencia para el manejo de la sedoanalgesia y delirium en el paciente adulto críticamente enfermo.

Given the importance of the management of sedation, analgesia and delirium in Intensive Care Units, and in order to update the previously published guidelines, a new clinical practice guide is presented, addressing the most relevant management and intervention aspects based on the recent literature. A group of 24 intensivists from 9 countries of the Pan-American and Iberian Federation of Societies of Critical Medicine and Intensive Therapy met to develop the guidelines. Assessment of evidence quality and recommendations was made according to the Grading of Recommendations Assessment, Development and Evaluation Working Group. A systematic search of the literature was carried out using MEDLINE, Cochrane Library databases such as the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials (CENTRAL), the Database of Abstracts of Reviews of Effects, the National Health Service Economic Evaluation Database and the database of Latin American and Caribbean Literature in Health Sciences (LILACS). A total of 438 references were selected. After consensus, 47 strong recommendations with high and moderate quality evidence, 14 conditional recommendations with moderate quality evidence, and 65 conditional recommendations with low quality evidence were established. Finally, the importance of initial and multimodal pain management was underscored. Emphasis was placed on decreasing sedation levels and the use of deep sedation only in specific cases. The evidence and recommendations for the use of drugs such as dexmedetomidine, remifentanil, ketamine and others were incremented.

Avaliação da influência da agitação ultrassônica na resistência de união de dois materiais reparadores utilizados para selar perfurações na furca / Assessment of the influence of ultrasonic agitation on the joint resistance of two repairing materials used to seal perforations in the burning / Evaluación de la influencia de la agitación ultrasónica en la resistencia de la unión de dos materiales de reparación utilizados para sellar otras perforaciones

Avaliou-se a influência da utilização da agitação ultrassônica na resistência de união à dentina, por meio de push-out, proporcionada pelos cimentos MTA-Angelus branco (MTA) e Biodentine (BD), empregados no selamento de perfurações de furca. Foram utilizados 48 primeiros ou segundos molares inferiores, com raízes não fusionadas, distantes cerca de 2 mm entre si na porção cervical das mesmas. Os dentes foram acessados e, em seguida, as raízes foram seccionadas transversalmente abaixo da junção cemento-esmalte. Os dentes foram montados em blocos de silicona de adição e perfurações de furca realizadas em seus assoalhos paralelamente ao longo eixo dos dentes e perpendiculares aos assoalhos dentais. A amostra foi dividida em quatro grupos (n = 12) em função do material reparador e da utilização ou não da agitação ultrassônica (AU). Quando empregada, a AU foi aplicada em 2 ciclos de 20 segundos por meio de inserto cônico liso acionado por ultrassom piezoelétrico. Concluídos os selamentos eles foram protegidos com cimento de ionômero de vidro e os dentes imersos em PBS. Decorridos 7 dias discos com 1 mm de altura foram retirados dos assoalhos dentais com auxílio de cortadora metalográfica e levados à máquina de ensaio universal. Os resultados expressos em MPa foram submetidos aos testes ANOVA dois fatores e de Bonferroni. Os maiores valores de resistência obtidos foram no grupo Biodentine com ultrassom (29,41 MPa), seguidos em ordem decrescente pelos grupos Biodentine sem ultrassom; MTA com ultrassom e MTA sem ultrassom (3,72 MPa). Nas condições do estudo concluiu-se que o BD apresentou maior resistência de união à dentina radicular; ainda, que a agitação ultrassônica influenciou positivamente na resistência de união do material à dentina.

We evaluated the influence of the use of ultrasonic agitation on the resistance to the dentin, by means of push-out, provided by the white MTA-Angelus (MTA) and Biodentine (BD) cements, used in the sealing of drilling holes. 48 first or second lower molars were used, with unfused roots, about 2 mm apart in the cervical portion of them. The teeth were accessed and then the roots were sectioned transversely below the cementenamel junction. The teeth were mounted in addition silicon blocks and hole drills performed on their floors parallel along the axis of the teeth and perpendicular to the dental floorings. The sample was divided into four groups (n = 12) depending on the repair material and whether ultrasonic agitation (AU) was used. When employed, the AU was applied in 2 20-second cycles by means of a smooth conical insert activated by piezoelectric ultrasound. Once the seals were completed, they were protected with glass ionomer cement and the teeth immersed in PBS. After 7 days, 1 mm high disks were removed from the dental floorboards with the aid of a metallographic cutter and taken to the universal test machine. Results expressed in MPa were submitted to two-factor and Bonferroni ANOVA tests. The highest resistance values obtained were in the group Biodentine with ultrasound (29.41 MPa), followed in descending order by the groups Biodentine without ultrasound; MTA with ultrasound and MTA without ultrasound (3.72 MPa). Under the conditions of the study, it was concluded that BD showed greater resistance to root dentin binding; also, that ultrasonic agitation positively influenced the resistance of the material to dentin binding.

influencia del uso de la agitación ultrasónica sobre la resistencia de la unión a la dentina se evaluó mediante un estiramiento, proporcionado por los cementos blancos (MTA) y biodentinos (BD) MTA-Angelus, empleados en el sello de los taladros. Se utilizaron los primeros o segundos molares inferiores, con raíces sin fundir, a unos 2 mm de distancia en la porción cervical de las raíces. Se accedió a los dientes y luego las raíces se seccionaron transversalmente por debajo de la unión cemento-enamel. Los dientes se ensamblaron además bloques de silicona y agujeros de perforación en sus pisos a lo largo del eje de los dientes y perpendiculares al suelo dental. La muestra se dividió en cuatro grupos (n = 12) según el material de reparación y si se utilizó o no la agitación ultrasónica (AU). Cuando se empleó, la UA se aplicó en 2 ciclos de 20 segundos mediante una inserción cónica suave activada por ultrasonido piezoeléctrico. Una vez concluidos los sellos, se protegieron con cemento ionómero de vidrio y los dientes se sumergieron en PBS. Al cabo de 7 días, los discos de 1 mm de altura se retiraron del suelo de corte metálico y se llevaron a la máquina de ensayo universal. Los resultados expresados como MPa se presentaron a las pruebas de dos factores ANOVA y Bonferroni. Los valores de resistencia más altos obtenidos fueron en el grupo de Biodentina con ultrasonido (29,41 MPa), seguidos en orden descendente por los grupos de Biodentina sin ultrasonido; MTA de ultrasonido y MTA libre de ultrasonido (3,72 MPa). En las condiciones del estudio se concluyó que la DB mostró mayor resistencia de la unión a la dentina raíz; y que la agitación ultrasónica tuvo una influencia positiva en la resistencia del material a la dentina.

[New medical approach to out-of-hospital treatment of psychomotor agitation in psychiatric patients: a report of 14 cases]. / Nuevo abordaje farmacológico en la agitación psicomotriz en pacientes psiquiátricos tratados en el medio extrahospitalario. A propósito de 14 casos.

OBJECTIVES: This case series explored the usefulness of an inhaled dose of 9.1 mg of loxapine administered outside the hospital to treat psychomotor agitation related to schizophrenia, bipolar disorder, or schizoaffective disorder. The Clinical Global Impression Scale and the Positive and Negative Syndrome Scale (excitement component) were used to assess the effects of treatment in 14 patients. The treatment was useful in 12 patients, who showed significant improvement (P<.001) after inhalation. We conclude that inhaled loxapine is useful for treating out-of-hospital psychomotor agitation related to a psychiatric disorder. Mechanical restraint and parenteral medication can be avoided after use of this drug. Loxapine treatment shortens the agitation episode and attenuates the impact on the patient, facilitating ambulance transfer.

OBJETIVO: El presente artículo evalúa la utilidad de la dosis de 9,1 mg de loxapina inhalada, administrada en el medio extrahospitalario, en el tratamiento de la agitación psicomotriz asociada a esquizofrenia, trastorno bipolar y trastorno esquizoafectivo. Se emplearon la Escala de Impresión Clínica Global y la Escala de Síntomas Positivos y Negativos - Componente de Excitación. Se atendieron un total de catorce pacientes. En doce de ellos el tratamiento se mostró útil, con una diferencia significativa entre los momentos previos y posteriores al tratamiento (p < 0,001). Se concluye que la loxapina inhalada es una opción útil en el medio extrahospitalario para el control de la agitación psicomotriz de causa psiquiátrica. Evita la contención mecánica y la necesidad de terapia farmacológica por vía parenteral. El tratamiento permite acortar la duración del episodio y atenuar su repercusión en el paciente, sin producir sedación y facilitando su traslado en ambulancia.

[Incidence of acute agitation and variation in acute agitation management by emergency services]. / Incidencia y variabilidad de manejo de la agitación aguda en los servicios de emergencias médicas.

OBJECTIVES: To describe the management of acute agitation by Spanish emergency medical services (EMS) and assess the incidence of acute agitation. MATERIAL AND METHODS: Observational descriptive study based on aggregate data from unpublished internal EMS reports. RESULTS: Seven participating emergency services received 4 306 213 emergency calls in 2013; 111 599 (2.6%, or 6.2 calls per 1000 population) were categorized as psychiatric emergencies. A total of 84 933 interventions (4.2%, or 4 per 1000 population) were required; 37 951 of the calls concerned agitated patients (1.9%, or 2 cases per 1000 population). Only 3 EMS mandated a specific procedure for their responders to use in such cases. CONCLUSION: The agitated patient is a common problem for EMS responders. Few teams apply specific procedures for managing these patients.

OBJETIVO: Evaluar la incidencia y el manejo de la agitación aguda por los servicios de emergencias médicas (SEM) en España.

RESULTADOS: Durante el año 2013, los 7 SEM participantes recibieron 4.306.213 llamadas, de las cuales 111.599 (2,6%; 6,2 llamadas/1.000 habitantes) fueron categorizadas como psiquiátricas. Las actuaciones requeridas por motivos psiquiátricos fueron 84.933 (4,2% del total de actuaciones; 4,0 actuaciones/1.000 habitantes) y, de estas, 37.951 fueron por pacientes agitados (1,9% del total de actuaciones; 2,0 actuaciones/1.000 habitantes). Solo 3 SEM disponían de un procedimiento específico para los equipos asistenciales de atención al paciente psiquiátrico y al paciente agitado. CONCLUSIONES: El paciente agitado es un problema común en los equipos asistenciales de los SEM. Pocos de estos equipos cuentan con procedimientos específicos de actuación ante estos casos.

Adolescente con corea de inicio agudo: a propósito de una entidad olvidada / Adolescent with acute-onset chorea: on the subject of a forgotten entity

La corea de Sydenham es como se denomina el cuadro de origen neurológico consistente en agitación y movimientos anormales que ocurre en contexto de una fiebre reumática, secundariamente a la infección por estreptococo del grupo A. Dado que la incidencia de fiebre reumática ha disminuido significativamente en los últimos años, las complicaciones asociadas pueden considerarse actualmente excepcionales. No obstante, dado que presenta un pronóstico excelente si se instaura precozmente el tratamiento, es muy importante saber reconocer el cuadro clínico (AU)

Guía práctica para el manejo de la agitación psicomotora en pediatría / Clinical Guide for the management of psychomotor agitation in pediatrics

La agitación psicomotora es un estado de hiperactividad impulsiva aguda en grados variables, que requiere intervención. Sus manifestaciones abarcan un amplio espectro desde mínima inquietud hasta perturbaciones intensas con grandes movimientos no propositivos o violentos. Datos recientes muestran que aproximadamente 10-20% de los niños, niñas y adolescentes (NNA) presenta una patología de la esfera psiquiátrica y/o abuso de sustancias y, en consecuencia, han aumentado las consultas por estos motivos en servicios de urgencia pediátrica. Hasta 1 de cada 15 NNA requiere contención de algún tipo. Las causas de agitación son múltiples y se deben investigar en cada paciente. El objetivo de este trabajo es concientizar al equipo de salud sobre el problema y contribuir a la estandarización del manejo clínico en pediatría. Se describen intervenciones no farmacológicas, contención farmacológica y física, con sus respectivas indicaciones.

Psychomotor agitation is a state of acute impulsive hyperactivity with varying degrees of magnitude that requires intervention. Its manifestations cover a broad spectrum from minimal unrest to intense disturbances with large non-purposeful or violent movements. Recent data show that approximately 10-20% of children and adolescents have a psychiatric disease and/or substance abuse disorder and, consequently, consultations for these reasons have increased in pediatric emergency services. Up to 1 in 15 children require some form of restraint. Causes of agitation are multiple and must be investigated in each patient. The objectives of this review are to improve awareness of the issue to health work-teams and aims at the standardization of its medical management in pediatrics. Non-pharmacological interventions, chemical and physical restraint methods are described, with their respective indications.

Intervención no farmacológica en la amnesia postraumática, una revisión sistemática / Non-pharmacological intervention in post-traumatic amnesia, a systematic review

Introducción: Las personas que sobreviven a un traumatismo craneoencefálico pueden presentar un estado transitorio de confusión y perturbación global del funcionamiento cognitivoconductual denominado amnesia postraumática. Objetivo: Describir las características, la calidad metodológica y los principales resultados de los estudios que han analizado el impacto de las intervenciones no farmacológicas en el tratamiento de los síntomas asociados a la amnesia postraumática. Pacientes y métodos: Siguiendo las directrices PRISMA, se realizó una búsqueda bibliográfica de los trabajos publicados en las bases de datos PubMed y PsycInfo durante los últimos 20 años (2000-2020). La calidad metodológica de los artículos se evaluó mediante la escala PEDro. Resultados: Tras aplicar los criterios de inclusión y exclusión, de los 1.036 artículos potencialmente interesantes, ocho cumplieron los criterios de elegibilidad; de estos, cuatro eran ensayos clínicos aleatorizados. Las intervenciones aplicadas se agruparon de la siguiente forma: reentrenamiento estructurado de las actividades de la vida diaria (cuatro estudios), programa de orientación a la realidad (dos estudios), sistema Perceive, Recall, Plan and Perform (un estudio) y aplicación terapéutica de la música (un estudio). Siete de los ocho artículos revisados mostraron resultados positivos o parcialmente positivos. Conclusiones: De acuerdo con los resultados obtenidos, hay indicios de que las intervenciones no farmacológicas tienen efectos positivos en la disminución de la sintomatología cognitivoconductual asociada a la amnesia postraumática.(AU)

Introduction: Survivors of traumatic brain injury may experience a transient state of confusion and global disturbance of cognitive-behavioural functioning called post-traumatic amnesia.Aim. To describe the characteristics, methodological quality and main results of studies that have analysed the impact of non-pharmacological interventions in the treatment of symptoms associated with post-traumatic amnesia. Patients and methods: Following the PRISMA guidelines, a literature search was carried out on papers published in the PubMed and PsycInfo databases over the last 20 years (2000-2020). The methodological quality of the articles was assessed using the PEDro scale. Results: After applying the inclusion and exclusion criteria, of the 1,036 potentially interesting articles, eight met the eligibility criteria, four of which were randomised clinical trials. The interventions applied were grouped as follows: structured retraining of activities of daily living (four studies), reality orientation programme (two studies), Perceive, Recall, Plan and Perform system (one study) and therapeutic application of music (one study). Seven of the eight articles reviewed showed positive or partially positive results. Conclusions: According to the results obtained, there is evidence that non-pharmacological interventions have positive effects on reducing the cognitive-behavioural signs and symptoms associated with post-traumatic amnesia.(AU)

La musicoterapia como alternativa para el control de la agitación y sedación de pacientes con ventilación mecánica invasiva / Music therapy as an alternative to control psychomotor agitation and sedation of the patients with invasive mechanical ventilation

RESUMEN * Introducción: Se promueve la utilización de la musicoterapia para el manejo de determinados problemas de salud. Objetivo: Precisar el efecto de la musicoterapia sobre la sedación de pacientes con ventilación mecánica invasiva en la Unidad de Cuidados Intensivos del Hospital General Docente "Dr. Agostinho Neto" de Guantánamo en 2018. Método: Durante enero-diciembre de 2018, se realizó un preexperimento con la aplicación de musicoterapia. Participaron 40 pacientes durante el proceso de destete de la ventilación mecánica invasiva. Aleatoriamente, se asignaron a un grupo estudio (n=20) que se les ofreció musicoterapia y a un grupo control (n=20) que no se les ofreció esta terapéutica. Se estudiaron las modificaciones de la frecuencia cardiaca, frecuencia respiratoria, presión arterial media, dosis de sedantes y el nivel de agitación, criterios de profesionales y pacientes respecto a esta técnica. Los datos se resumieron mediante frecuencias absolutas, porcentajes, media y la desviación típica y las diferencias se evaluaron con la técnica t de Students. Resultados: La musicoterapia mejoró la presión arterial media, frecuencia cardiaca y respiratoria, disminuyó las dosis utilizadas de sedantes y mejoró la agitación en el grupo estudio (p<0,05). Los profesionales y pacientes ofrecieron criterios favorables respecto a sus bondades para el control de la agitación (p<0,05). Conclusiones: La musicoterapia es una terapia no farmacológica útil para el control de la agitación del paciente durante el proceso de destete de la ventilación mecánica invasiva.

ABSTRACT * Introduction: Music therapy is promoted as a tool to handle certain health issues. Objective: To specify the effect of music therapy in sedated patients with invasive mechanical ventilation in the intensive care unit at the General Teaching Hospital ¨Dr. Agostinho Neto¨ in Guantanamo during the year 2018. Method: From January to December, 2018, a pre-experimental application of music therapy was undertaken. 40 patients were part of the experiment, during the process of weaning from invasive mechanical ventilation. Patients were randomly selected to the studied group (n=20) or to a control group (n=20), the first being treated with music therapy while the last was not. Modifications in heart rate, respiratory rate, mean arterial pressure, sedative dose and levels of psychomotor agitation were taken into account; also listening to professionals´ and patients´ opinions on the treatment. The information gathered was sorted in absolute frequencies, percentages, mean and standard deviation, and the differences were evaluated with Student´s t-distribution. Results: Music therapy improved heart and respiratory rate, mean arterial pressure and helped to decrease the use of sedative doses; besides, it improved the agitation in the group studied (p<0.05). Patients and professionals both gave favorable opinions about the treatment and its ability to control the agitation (p<0.05). Conclusions: Music therapy constitutes a non-pharmacological form of therapy that proves effective to control agitation in patients during the process of weaning from invasive mechanical ventilation.

Assessment of delirium in children admitted into the Intensive Care Unit: psCAM-ICU Tool

Abstract Background: Delirium has been identified as a risk factor for the mortality of critically ill patients, generating great social and economic impacts, since patients require more days of mechanical ventilation and a prolonged hospital stay in the intensive care unit (ICU), thus increasing medical costs. Objective: To describe the prevalence and characteristics of delirium episodes in a sample of 6-month to 5-year-old children who are critically ill. Methods: Cohort study at a Pediatric Intensive Care Unit (PICU) in Bogotá (Colombia). Participants were assessed by the Preschool Confusion Assessment Method for the ICU (psCAM-lCU) within the first twenty-four hours of hospitalization. Results: One quarter of the participants (25.8%) presented some type of delirium. Among them, two sub-types of delirium were observed: 62.5% of the cases were hypoactive and 37.5% hyperactive. Moreover, from them, six were male (75%) and 2 female (25%). Primary diagnosis was respiratory tract infection in 62.55% of the patients, while respiratory failure was diagnosed in the remaining 37.5%. Conclusions: The implementation of delirium monitoring tools in critically ill children provides a better understanding of the clinical manifestation of this phenomenon and associated risk factors in order to contribute to the design of efficient intervention strategies.

Resumen Introducción: el delirium se ha identificado como un factor de riesgo para la mortalidad de pacientes en estado crítico, lo que genera un mayor impacto social y económico, teniendo en cuenta que los pacientes requieren más días de ventilación mecánica y una estancia hospitalaria prolongada en la unidad de cuidados intensivos (UCI), lo que incrementa los costos médicos de su estadía. Objetivo: describir la prevalencia y las características de los episodios de delirium en una muestra de niños de seis meses a cinco años en estado crítico. Métodos: estudio de cohorte en una Unidad de Cuidados Intensivos Pediátricos (UCIP) en Bogotá (Colombia). Los participantes fueron evaluados por el método de evaluación de confusión preescolar para la UCI (psCAM-UCI) dentro de las 24 horas iniciales del período de hospitalización. Resultados: una cuarta parte de los participantes (25,8 %) presentó algún tipo de delirium. Entre ellos, se observaron dos subtipos de delirium: el 62,5 % de los casos era hipoactivo y el 37,5 % hiperactivo. Además, el 75% (6) de los participantes delirantes eran hombres y el 25 % (2) mujeres. En 62,5 % de los pacientes el diagnóstico primario fue infección de las vías respiratorias, mientras que la insuficiencia respiratoria fue diagnosticada en el 37,5 % restante. Conclusiones: la implementación de herramientas de monitoreo del delirium con niños en estado crítico proporciona una mejor comprensión de la presentación clínica de este fenómeno y los factores de riesgo asociados, con lo cual es posible contribuir al diseño de estrategias de intervención eficientes.

Resumo Introdução: o delirium foi identificado como um fator de risco para a mortalidade de pacientes graves, o que gera maior impacto social e econômico, visto que os pacientes necessitam de mais dias de ventilação mecânica e internação prolongada na unidade de terapia intensiva (UTI), o que aumenta os custos médicos para a sua estadia. Objetivo: descrever a prevalência e as características dos episódios de delirium em uma amostra de crianças de 6 meses a 5 anos, gravemente doentes. Métodos: estudo de coorte em uma Unidade de Terapia Intensiva Pediátrica (UTIP) em Bogotá (Colômbia). Os participantes foram avaliados pelo método de avaliação de confusão pré-escolar para a UTI (psCAM-UTl) dentro das primeiras 24 horas do período de internação. Resultados: um quarto dos participantes (25,8%) apresentou algum tipo de delirium. Entre eles, dois subtipos de delirium foram observados: 62,5% dos casos eram hipoativos e 37,5% hiperativos. Além disso, 75% (6) dos participantes delirantes eram do sexo masculino e 25% (2) feminino. Em 62,5 % dos pacientes, o diagnóstico primário foi infecção das vias respiratórias, enquanto a insuficiência respiratória foi diagnosticada em 37,5 % restante. Conclusões: a implementação de instrumentos de monitorização do delirium com crianças gravemente doentes permite uma melhor compreensão da apresentação clínica do fenômeno e dos fatores de risco associados, de forma a contribuir para o desenho de estratégias de intervenção eficazes.
