ABSTRACT

O sugamadex é uma droga nova e revolucionária desenvolvida como antagonista seletivo dos agentes bloqueadores neuromusculares (ABNM) esteroides (rocurônio > vecurônio ¼ pancurônio). O medicamento é uma y-ciclodextrina modificada e hidrossolúvel que forma um composto estável com o ABNM na razão de 1:1. Ele se liga ao ABNM livre no plasma, criando um gradiente de concentração que desloca o ABNM dos receptores nicotínicos na junção neuromuscular, levando à reversão completa e duradoura do BNM. O sugamadex não se liga às proteínas ou a qualquer outro receptor no organismo, o que lhe confere ótimo perfil de tolerância. O sugamadex pode ser usado na reversão do BNM profundo, promovendo recuperação mais rápida em relação à succinilcolina. Seu emprego pode diminuir a necessidade de monitorização do BNM, a incidência de bloqueio residual e ainda evitar os efeitos adversos causados pelos anticolinesterásicos e anticolinérgicos. Entretanto, também há limitações em relação à utilização 00 sugamadex. Ele impede o uso dos AB- NMs esteroides durante 24 horas, caso seja necessário novo BNM, e pode aumentar o risco do emprego desnecessário e indiscriminado dos ABNMs. Além disso, faltam dados da sua utilização em alguns grupos populacionais e de seu uso em larga escala. Por fim, deve-se considerar também o fator econômico, visto que se trata de uma droga nova e de valor ainda elevado no mercado...


Sugammadex is a novel and unique compaund designed as a selective antaganist ot steroidal neuromuscular blaeking agents (NMBA) (rocuronium>vecuronium¼pancuronium). The drug is a modified water-saluble y-cyclodextrin that forms a stable complex at a 1:1 ratio with the NMBA. It combines with the NMBA creating a concentration gradient favoring the movement ot the NMBA from the nicotine receptors ot the neuromuscular junction leading to the complete and lasting reversal af the neuromuscular blockade (NMB). Sugamadex does not bind to plasma proteins or any other receptors system in the body what provides him a great tolerance profile. Sugamadex can be used in the reversal af deep neuromuscular blockade with a faster recovery time in relation to succinylcholine. Its use can diminish the necessity af monitoring af the NMB, the incidence ot residual blockade and still prevent the adverse effects caused by the antiecholinesterase and anticholinergic drugs. However, there are limitatians regarding the use af Sugammadex. It hinders the use ot the steroidal NMBA during 24 hours if a new NMB must be restablished and it can increase the risk ot unnecessary and indiscriminate use af the NMBA. Mareaver, there is a laek ot data regarding the its use in some population groups and in large scale. Final/y, the economic factor must be also considered, since it is a new drug with a still raised value in market...

ABSTRACT

OBJECTIVES: To study the utilization pattern and the cost of sedatives, analgesics and neuromuscular blocking agents in a multidisciplinary intensive care unit (ICU) METHODS: A prospective observational study was conducted in the ICU of the Eric Williams Medical Sciences Complex, Trinidad and Tobago, for a period of twelve weeks. All patients admitted to the ICU were enrolled. No interventions were done. Data collected included demographics, diagnoses on admission, length of stay in the ICU, status of mechanical ventilation, patient outcome, quantity of sedatives, analgesics and neuromuscular blocking agents used in every patient and their cost. RESULTS: There were 333 patient-days encountered from 34 patients studied. Midazolam, fentanyl and cisatracurium were the most commonly used sedative, opioid and neuromuscular blocking agents respectively. The total cost of drugs used for sedation, analgesia and neuromuscular blockade was approximately US$ 19 600 per annum. Cost for this treatment alone accounted for more than 50% of the total ICU drug costs. The costs were significantly higher in patients who stayed more than two weeks in the ICU when compared to those who stayed less than two weeks (p < 0.001). CONCLUSIONS: The study highlights the utilization pattern and financial burden of sedation, analgesia and neuromuscular blockade in the delivery of critical care.


OBJETIVOS: Estudiar el patrón de utilización y costo de los sedantes, analgésicos, y agentes de bloqueo neuromuscular en una Unidad Multidisciplinaria de Cuidados Intensivos (UCI). MÉTODOS: Se llevó a cabo un estudio prospectivo en la UCI del Complejo de Ciencias Médicas Eric Williams, en Trinidad y Tobago, por un período de doce semanas. Todos los pacientes ingresados a la UCI fueron enrolados. No se realizaron intervenciones. Los datos recogidos incluyeron demografías, diagnósticos de ingreso, longitud de la estadía en la UCI, estatus de ventilación mecánica, evolución del paciente, así como la cantidad y el costo de los sedantes, analgésicos y agentes de bloqueo neuromuscular usados en cada paciente. RESULTADOS: Se encontraron 333 días-pacientes a partir de 34 pacientes estudiados. La midazolama, el fentanil y el cisatracurio fueron los agentes sedativos, opioides y de bloqueo neuromuscular más comúnmente usados. El costo total de los medicamentos usados para la sedación, la analgesia y el bloqueo neuromuscular fue de aproximadamente $19 600 USD por año. El costo sólo para este tratamiento representó más del 50% del total de los costos de medicamentos de la UCI. Los costos fueron significativamente más altos en pacientes que permanecieron más de dos semanas en la UCI, en comparación con aquellos que permanecieron menos de dos semanas (p < 0.001). CONCLUSIONES: El estudio pone de relieve el patrón de utilización de la carga financiera de la sedación, analgesia y bloqueo muscular a la hora de ofrecer atención crítica.
