Perioperative neuromuscular blockade. 2020 update of the SEDAR (Sociedad Española de Anestesiología y Reanimación) recommendations.

We present an update of the 2020 Recommendations on neuromuscular blockade of the SEDAR. The previous ones dated 2009. A modified Delphi consensus analysis (experts, working group, and previous extensive bibliographic revision) 10 recommendations were produced1: neuromuscular blocking agents were recommended for endotracheal intubation and to avoid faringo-laryngeal and tracheal lesions, including critical care patients.2 We recommend not to use neuromuscular blocking agents for routine insertion of supraglotic airway devices, and to use it only in cases of airway obstruction or endotracheal intubation through the device.3 We recommend to use a rapid action neuromuscular blocking agent with an hypnotic in rapid sequence induction of anesthesia.4 We recommend profound neuromuscular block in laparoscopic surgery.5 We recommend quantitative monitoring of neuromuscular blockade during the whole surgical procedure, provided neuromuscular blocking agents have been used.6 We recommend quantitative monitoring through ulnar nerve stimulation and response evaluation of the adductor pollicis brevis, acceleromyography being the clinical standard.7 We recommend a recovery of neuromuscular block of at least TOFr ≥ 0.9 to avoid postoperative residual neuromuscular blockade.8 We recommend drug reversal of neuromuscular block at the end of general anesthetic, before extubation, provided a TOFr ≥ 0.9 has not been reached.9 We recommend to choose anticholinesterases for neuromuscular block reversal only if TOF≥2 and a TOFr ≥ 0.9 has not been attained.10 We recommend to choose sugammadex instead of anticholinesterases for reversal of neuromuscular blockade induced with rocuronium.

Bloqueo neuromuscular perioperatorio. Actualización 2020 de las Recomendaciones de la Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor (SEDAR) / Perioperative neuromuscular blockade. 2020 update of the SEDAR (Sociedad Española de Anestesiología y Reanimación) recommendations

Se presenta la actualización 2020 de las Recomendaciones de bloqueo neuromuscular de la Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor (SEDAR). Las anteriores databan de 2009. Tras un análisis de consenso Delphi (expertos, grupo de trabajo y revisión bibliográfica previa) se generaron 10 recomendaciones: 1) Se recomienda el uso de fármacos bloqueantes neuromusculares (fbnm) para facilitar la intubación traqueal y evitar lesiones faringo-laringo-traqueales en cualquier paciente, incluidos pacientes críticos. 2) Se recomienda no utilizar fbnm para la inserción rutinaria de dispositivos supraglóticos y utilizar solo en caso de obstrucción de la vía aérea o intubación traqueal a través de este. 3) Se recomienda utilizar un fármaco bloqueante neuromuscular de inicio de acción rápido asociado al agente hipnótico en la inducción de secuencia rápida. 4) Se recomienda utilizar un nivel de bloqueo neuromuscular profundo en cirugía laparoscópica. 5) Se recomienda el uso de monitorización cuantitativa del bloqueo neuromuscular durante todo el procedimiento quirúrgico, siempre que se utilicen fbnm. 6) Se recomienda la monitorización cuantitativa mediante estimulación del nervio cubital y evaluación de la respuesta en el músculo aductor corto del pulgar, siendo el estándar clínico la aceleromiografía (AMG). 7) Se recomienda una recuperación del bloqueo neuromuscular al menos hasta alcanzar un TOFr ≥ 0,9 para evitar el bloqueo neuromuscular residual postoperatorio. 8) Se recomienda la reversión farmacológica del bloqueo neuromuscular al finalizar la anestesia general, previo a la extubación traqueal siempre que no se haya alcanzado un TOFr ≥ 0,9. 9) Se recomienda utilizar fármacos anticolinesterásicos para la reversión del bloqueo neuromuscular solo cuando el tren de cuatro estímulos (TOF) es ≥ 2 y no se haya alcanzado un TOFr ≥ 0,9. 10)...(AU)

Recommendations on the use of deep neuromuscular blockade by anaesthesiologists and surgeons. AQUILES (Anestesia QUIrúrgica para Lograr Eficiencia y Seguridad) Consensus. / Recomendaciones sobre el uso de bloqueo neuromuscular profundo por parte de anestesiólogos y cirujanos. Consenso AQUILES (Anestesia QUIrúrgica para Lograr Eficiencia y Seguridad).

INTRODUCTION: Neuromuscular blockade enables airway management, ventilation and surgical procedures. However there is no national consensus on its routine clinical use. The objective was to establish the degree of agreement among anaesthesiologists and general surgeons on the clinical use of neuromuscular blockade in order to make recommendations to improve its use during surgical procedures. METHODS: Multidisciplinary consensus study in Spain. Anaesthesiologists experts in neuromuscular blockade management (n=65) and general surgeons (n=36) were included. Delphi methodology was selected. A survey with 17 final questions developed by a dedicated scientific committee was designed. The experts answered the successive questions in two waves. The survey included questions on: type of surgery, type of patient, benefits/harm during and after surgery, impact of objective neuromuscular monitoring and use of reversal drugs, viability of a multidisciplinary and efficient approach to the whole surgical procedure, focussing on the level of neuromuscular blockade. RESULTS: Five recommendations were agreed: 1) deep neuromuscular blockade is very appropriate for abdominal surgery (degree of agreement 94.1%), 2) and in obese patients (76.2%); 3) deep neuromuscular blockade maintenance until end of surgery might be beneficial in terms of clinical aspects, such as as immobility or better surgical access (86.1 to 72.3%); 4) quantitative monitoring and reversal drugs availability is recommended (89.1%); finally 5) anaesthesiologists/surgeons joint protocols are recommended. CONCLUSIONS: Collaboration among anaesthesiologists and surgeons has enabled some general recommendations to be established on deep neuromuscular blockade use during abdominal surgery.

Efecto antidepresivo de dosis subanestésicas de ketamina en el postoperatorio de una paciente con depresión no controlada / Effect of sub-anaesthetic doses of ketamine in the postoperative period in a patient with uncontrolled depression

Estudios recientes indican que la infusión intravenosa de clorhidrato de ketamina (antagonista de los receptores N-metil-D-aspartato) conlleva una rápida reducción de la sintomatología depresiva. Una mujer de 42 años, con cáncer de mama y depresión mayor resistente a tratamiento médico recibió una infusión intravenosa de 0,3mg/kg de ketamina en 90min durante 5 días consecutivos. Se apreció una disminución significativa de la sintomatología evaluada mediante la escala de depresión de Hamilton de 22 a 13 (-41%) con un efecto mantenido a los 14 días. Se discute el posible mecanismo terapéutico(AU)
