Practices related to assessment of sedation, analgesia and delirium among critical care pediatricians in Brazil.

OBJECTIVE: To understand the use of tools, protocols and comfort measures related to sedation/analgesia, and to screen the occurrence of delirium in pediatric intensive care units. METHODS: A survey with 14 questions was distributed by e-mail to Brazilian critical care pediatricians. Eight questions addressed physician and hospital demographics, and six inquired practices to assess sedation, analgesia, and delirium in pediatric intensive care units. RESULTS: Of 373 questionnaires sent, 61 were answered (16.3%). The majority of physicians were practicing in the Southeast region (57.2%). Of these, 46.5% worked at public hospitals, 28.6% of which under direct state administration. Of respondents, 57.1% used formal protocols for sedation and analgesia, and the Ramsay scale was the most frequently employed (52.5%). Delirium screening scores were not used by 48.2% of physicians. The Cornell Assessment of Pediatric Delirium was the score most often used (23.2%). The majority (85.7%) of physicians did not practice daily sedation interruption, and only 23.2% used non-pharmacological measures for patient comfort frequently, with varied participation of parents in the process. CONCLUSION: This study highlights the heterogeneity of practices for assessment of sedation/analgesia and lack of detection of delirium among critical care pediatricians in Brazil.

RESUMO Objetivo Compreender o uso de ferramentas, protocolos e medidas de conforto relacionadas à sedação/analgesia, além de rastrear a presença de delirium em unidades de terapia intensiva pediátricas. Métodos Um inquérito com 14 questões foi distribuído, por meio de correio eletrônico, para médicos pediatras intensivistas brasileiros. Oito questões eram sobre os dados demográficos dos médicos e dos hospitais, e seis questões eram sobre as práticas na avaliação da sedação, analgesia e delirium em unidades de terapia intensiva pediátrica. Resultados Responderam ao inquérito 61 médicos dos 373 e-mails enviados (taxa de resposta de 16,3%). A maioria dos médicos era da Região Sudeste (57,2%) e 46,5% trabalhavam em hospitais públicos, sendo 28,6% sob administração direta do Estado. Dos respondedores, 57,1% utilizavam protocolos formais de sedação e analgesia, sendo a escala de Ramsay a mais utilizada (52,5%). Não utilizavam escores de rastreamento de delirium 48,2% dos médicos, e o Cornell Asssessment of Pediatric Delirium (23,2%) foi o mais utilizado. A maioria (85,7%) dos médicos não utilizou a prática da interrupção diária da sedação, e apenas 23,2% utilizavam medidas não farmacológicas para o conforto do paciente com frequência, com a participação heterogênea dos pais nesse processo. Conclusão Este estudo destaca a heterogeneidade nas práticas de avaliação da sedação/analgesia e insuficiência de rastreamento de delirium entre os intensivistas pediátricos brasileiros.

Sedación y analgesia en pacientes con asistencia ventilatoria mecánica en unidades de cuidados intensivos pediátricos de Argentina / Sedation and analgesia in patients on mechanical ventilation in pediatric intensive care units in Argentina

Introducción. Los niños en unidades de cuidados intensivos pediátricos (UCIP) están expuestos a padecer dolor, estrés y ansiedad debido a su enfermedad, el tratamiento o el ambiente. La adecuada sedación y analgesia son fundamentales para su cuidado, especialmente, en aquellos que requieren asistencia ventilatoria mecánica (AVM). Objetivo. Determinar la práctica habitual en la sedación y analgesia de los pacientes que requieren ARM en UCIP de Argentina. Material y métodos. Estudio descriptivo, transversal, multicéntrico, realizado a través de encuestas enviadas por correo electrónico. Resultados. Se encuestaron y respondieron 45 UCIP. El 18% (N= 8) utiliza un protocolo de sedoanalgesia de seguimiento estricto, mientras que el 58% (N= 26) siguen un protocolo "tácito" producto de la automatización en la práctica. Las drogas más utilizadas son el midazolam para sedación y fentanilo para analgesia. El 31% (N= 14) de las UCIP monitorizan la sedación con escalas de evaluación (Ramsay modificada y/o Comfort). El 4% (N= 2) realizan la interrupción diaria de la sedación en forma programada. En pacientes de difícil sedación, la dexmedetomidina es la droga más utilizada como coadyuvante. El 73% (N= 33) de las unidades utilizan bloqueantes neuromusculares ante indicaciones precisas, y un monitoreo clínico. El 20% (N= 9) de las UCIP tienen un protocolo de destete para la sedoanalgesia, la morfina y lorazepam son las drogas más frecuentemente utilizadas. Conclusión. Existe un bajo porcentaje de protocolización en la práctica habitual del manejo de la sedoanalgesia en pacientes con AVM en las UCIP encuestadas.

Introduction. Children in pediatric intensive care units (PICUs) are exposed to experiencing pain, stress and anxiety due to their disease, treatment or care setting. Adequate sedation and analgesia are key to their care, particularly in patients requiring mechanical ventilation (MV). Objective. To determine the usual practice in sedation and analgesia management in patients requiring MV in PICUs in Argentina. Material and methods. Descriptive, crosssectional, multi-center study conducted by means of e-mailed surveys. Results. A total of 45 PICUs were surveyed, 18% (N= 8) of which follow a sedation and analgesia protocol strictly, while 58% (N= 26) follow an "implied" protocol based on routine practice. The most commonly used drugs were midazolam, for sedation, and fentanyl, for analgesia. In 31% (N= 14) of the PICUs, sedation was monitored through assessment scales (modified Ramsay and/or Comfort scales). In 4% (N= 2) of units, daily, scheduled interruptions of sedation was implemented. In patients who are difficult to sedate, dexmedetomidine was the most commonly used adjuvant. In 73% (N= 33) of the units, neuromuscular blocking agents were used in compliance with precise guidelines and under clinical monitoring. In 20% (N= 9) of the PICUs there was a sedation and analgesia weaning protocol in place, and morphine and lorazepam are the most commonly used drugs. Conclusion. Only a low percentage of surveyed PICUs had a protocol in place for the routine management of sedation and analgesia in patients on MV.

Chloral hydrate in pediatric magnetic resonance imaging: evaluation of a 10-year sedation experience administered by radiologists.

BACKGROUND: Chloral hydrate is a sedative that has been used for magnetic resonance imaging (MRI). OBJECTIVE: To evaluate the use, effectiveness and safety of chloral hydrate administered by radiologists for the sedation of children who require MRI procedures. MATERIALS AND METHODS: We retrospectively reviewed the clinical charts for all patients ages 0 - 10 years old who underwent sedation with chloral hydrate for MRI from January 2000 to December 2010. Demographic factors, dose information, indication for MRI, therapeutic failures and adverse reactions to the drug were reviewed. RESULTS: One thousand, seven hundred and three children (946 males, 757 females) with a median age of 2.5 years (range: 4 days - 9.91 years) received chloral hydrate. Moderate to deep sedation was achieved in 1,618/1,703 (95%) of the patients, 35/1,703 (2.1%) of the patients failed to achieve moderate to deep sedation, and 47/1,703 (2.8%) of the patients woke up during MRI examination. Adverse reactions were present in 31/1,703 (1.8%) of the patients. Three severe adverse reactions occurred (0.18%). A single dose of chloral hydrate (40-60 mg/kg) was administered to 1,477/1,703 patients (86.7%). An additional dose of chloral hydrate (10-20 mg/kg), given 15 min after the first dose or when the patient woke up during the MRI examination, was required in 226/1,703 patients (13.3%). The likelihood of requiring an additional dose in children older than 2 years was 2.2 times the likelihood compared to children younger than 2 years (OR = 2.2 [95%CI: 1.6-3.0]). The use of a reduced dose (<50 mg/kg) was not associated with a higher therapeutic failure rate (OR = 1.04 [95%CI 0.57-1.89]). CONCLUSION: Chloral hydrate is an appropriate sedation option for pediatric patients in MRI services when strict patient selection criteria are met. The use of a reduced dose does not affect the effectiveness of sedation. The lack of data regarding the presence of transient oxygen desaturation, the time to induce sedation and the exact duration of sedation are limitations of this study.
