RESUMO
Adults patients with congenital heart disease increasingly present for non cardiac surgery. The anesthetic management this type of patients in neurosurgery requires a meticulous surgical anesthetic planning. The need for urgent intervention, with the presence of a congenital heart disease evolved to Eisenmenger syndrome, associated to a difficult airway, is a challenge for the anesthesiologist. The use of dexmedetomidine may be a valid alternative. We present the case of a patient with Down syndrome, and Eisenmenger syndrome who underwent drainage of brain abscess from the emergency department and was subsequently scheduled for reintervention. We compare the different anesthetic techniques used in both procedures, analyzing the implications they had on the main physiopathological alterations presented by the patient.

The present work aims to establish a guide to action, agreed by anaesthesiologists and neurophysiologists alike, to perform effective intraoperative neurophysiological monitoring for procedures presenting a risk of functional neurological injury, and neurosurgical procedures. The first section discusses the main techniques currently used for intraoperative neurophysiological monitoring. The second exposes the anaesthetic and non-anaesthetic factors that are likely to affect the electrical records of the nervous system structures. This section is followed by an analysis detailing the adverse effects associated with the most common techniques and their use. Finally, the last section describes a series of guidelines to be followed upon the various intraoperative clinical events.

RESUMO
BACKGROUND: Postoperative Nausea and Vomiting (PONV) is a multifactorial surgical complication with an unclear underlying cause. Anesthetic methods, patients' characteristics and the type of surgery are considered as factors affecting PONV. This study was designed to compare the effect of inhalational and intravenous anesthesia in abdominal surgery on the incidence and severity of PONV. METHODS: A single-blinded prospective randomized clinical trial on 105 patients aged 18-65 years was carried out. Patients were divided in two groups of Total Intravenous Anesthesia (TIVA) and Inhalational anesthesia. The incidence and severity of PONV were examined at 0, 2, 6, 12, and 24hours after the surgery. The use of a rescue antiemetic was also evaluated. RESULTS: Fifty point nine percent of the patients in the inhalation group and 17.3% of the patients in the intravenous group developed PONV (p <0.001). The incidence of vomiting was reported in 11.3% of the Inhalational group and 3.8% of the TIVA group (p=0.15), and 24.5% of patients in the Inhalation group and 9.6% of patients in the intravenous group needed an antiemetic medication (p=0.043). CONCLUSION: The incidence of postoperative nausea and vomiting and the need for administration of an antiemetic rescue drug, and the severity of nausea in patients were significantly lower in the TIVA group.

INTRODUCTION: Cytoreductive surgery with hyperthermic intraoperative chemotherapy (HITHOC) is a therapeutic option for treatment of malignant pleural mesothelioma. Anesthetic management might be challenging. PATIENTS AND METHODS: A descriptive analysis of a case series is presented. Seven patients with malignant pleural mesothelioma diagnostic undergoing HITHOC surgery were studied. Combined general and epidural anesthesia were administered. An intensive hemodynamic monitorization was implemented. Data regarding perioperative course was analyzed. RESULTS: Between May 2015 and October 2018 7patients underwent HITHOC procedure. Blood transfusions were administered in all patients, and 5of the 7patients required vasoactive drug administration. Extubation at the end of the procedure was able in 6of the 7patients. The median length of stay in ICU was 4 days, and 29 days for the whole hospitalary stay. No significant postoperative pain was observed. CONCLUSIONS: HITHOC surgery is a complex procedure in which several hemodynamic changes occur. An intensive intraoperative monitorization was useful for controlling complications.

BACKGROUND: Postoperative pain represents an important concern when remifentanil is used for total intravenous anesthesia because of its ultrashort half-life. Longer acting opioids, such as sufentanil, have been used during induction of remifentanil-based total intravenous anesthesia as a means to overcome this shortcoming. However, the effectiveness and safety of such strategy still lacks evidence from randomized clinical trials. Hence, we aimed to assess the postoperative analgesic efficacy and safety of a single dose of sufentanil administered during the induction of remifentanil-based total intravenous anesthesia. METHODS: Forty patients, scheduled for elective open abdominal surgery, were randomized to receive remifentanil-based total intravenous anesthesia with or without a single dose of sufentanil upon induction. We assessed the postoperative morphine consumption administered through a patient-controlled analgesia pump. Self-reported pain scores and the occurrence of nausea, vomiting, pruritus, agitation, somnolence and respiratory depression were also assessed up to 2 days after surgery. RESULTS: The mean difference between the sufentanil and control groups regarding morphine consumption in the post-anesthetic care unit and at 12, 24 and 48h after surgery were -7.2mg (95%CI: -12.5 to -2.1, p<0.001), -3.9mg (95%CI: -11.9 to 4.7, p=0.26), -0.6mg (95%CI: (-12.7 to 12.7, p=0.80), and -1.8mg (95%CI: (-11.6 to 15.6, p=0.94), respectively. Neither self-reported pain nor the incidence of adverse events were significantly different between groups at any time point. CONCLUSION: Our findings suggest that the administration of sufentanil during induction of remifentanil-based total intravenous anesthesia is associated with decreased early postoperative opioid consumption.

El hiperaldosteronismo primario es una condición caracterizada por una producción excesiva de aldosterona, que no depende del sistema renina-angiotensina-aldosterona. Una de las manifestaciones clínicas más frecuentes es la hipertensión arterial resistente al tratamiento convencional. Se estima que aproximadamente el 10% de los casos de hipertensión secundaria están asociados con el hiperaldosteronismo primario, siendo aproximadamente el 50% de estos casos causados por un adenoma suprarrenal. Los tumores de las glándulas suprarrenales presentan desafíos para el anestesiólogo, requiriendo una evaluación preoperatoria minuciosa, un adecuado control hemodinámico durante el perioperatorio. El objetivo del presente caso clínico es reportar la utilización de la anestesia total intravenosa en una cirugía laparoscópica de tumor suprarrenal en un paciente con hiperaldosteronismo primario. Se busca describir la técnica anestésica empleada, evaluar la respuesta hemodinámica del paciente durante el procedimiento y analizar los resultados obtenidos en términos de estabilidad cardiovascular, control del dolor y prevención de complicaciones postoperatorias. Se presenta el caso de una paciente de 28 años con hipertensión arterial sistémica de 4 años de evolución, que ha sido difícil de controlar. Debido a la sospecha de hiperaldosteronismo primario, se llevó a cabo la prueba de cociente aldosterona/actividad de renina plasmática, la cual mostró niveles elevados. Como parte del manejo, se realizó una adrenalectomía izquierda laparoscópica bajo anestesia total intravenosa...(AU)

Congenital fibre type disproportion (CFTD) is a rare type of myopathy that is characterised by muscle weakness and hypotonia during childhood. Clinical features include motor delay, feeding difficulties, limb weakness, joint contractures, and scoliosis. A report is presented of the anaesthetic management of a 3-year-old girl with CFTD myopathy associated with a mutation of the TPM3 gene, scheduled for adenotonsillectomy because of obstructive sleep apnoea hypopnoea syndrome (OSAHS). The main concerns were the possible susceptibility to malignant hyperthermia, the risk of anaesthesia-induced rhabdomyolysis, a greater sensitivity to non-depolarising muscle relaxants, and the presence of OSAHS. Total intravenous anaesthesia with propofol and the use of rocuronium/sugammadex appear to be safe options. Given the high risk of respiratory compromise and other complications, patients should be closely monitored in the post-operative period.

BACKGROUND AND OBJECTIVES: There is a strong demand for fast and predictable anesthesia recovery with few side effects. Choice of the hypnotic agent could impact on that. This study investigated the differences between recoveries after remifentanil-propofol and remifentanil-desflurane anesthesias guided by bispectral index (BIS®). METHODS: Forty patients were randomly assigned into 2 groups according to the anesthesia technique applied: remifentanil-propofol (REM-PRO) and remifentanil-desflurane (REM-DES). After the discontinuation of the anesthetics, the times to extubation, to obey commands and to recover the airway protection reflex were recorted. In the post-anesthetic recovery room (PACU) it was recorded the occurrence of nausea and vomiting (PONV), scores of Ramsay sedation scale and of numeric pain scale (NPS), morphine dose and length of stay in the unit. RESULTS: Data from 38 patients were analyzed: 18 from REM-PRO and 20 from REM-DES group. Anesthesia times were similar (REM-PRO=193min, SD 79.9 vs. 175.7min, SD 87.9 REM-DES; p=0.5). REM-DES had shorter times than REM-PRO group: time to follow command (8.5min; SD 3.0 vs. 5.6min; SD 2.5; p=0.0) and extubation time (6.2 minutes; 3.1-8.5 vs. 9.5 minutes; 4.9-14.4; p=0.0). Times to recover airway protective reflex were similar: 16 patients from REM-PRO (88.9%) restored the airway protective reflex 2min after extubation vs. 17 from REM-DES (89.5%); and 2 patients from REM-PRO (11.1%) vs. 2 from REM-DES (10.5%) 6min after extubation, p=1. Ramsay sedation score, NPS, PONV incidents, morphine dose and PACU stay of length PACU were also similar. CONCLUSION: Remifentanil-desflurane-based anesthesia has a faster extubation time and to follow command than remifentanil-propofol-based anesthesia when both guided by BIS®.

Introducción: En los últimos años se ha iniciado un interés especial por la combinación de ketamina/propofol para pacientes intervenidos por procedimientos mínimamente invasivos. Objetivo: Evaluar la efectividad y seguridad de la anestesia intravenosa total con ketofol en concentración 1:4 contra la concentración 1:2 en pacientes intervenidos por cirugía mínimamente invasiva. Métodos: Estudio analítico, cuasiexperimental, prospectivo y longitudinal, en el Hospital Universitario General Calixto García entre diciembre de 2019 a diciembre de 2020, en 30 pacientes divididos en dos grupos de 15 pacientes: grupo estudio (GE): Ketofol 1:4 y grupo control (GC): Ketofol 1:2. Se analizaron: tensión arterial media y frecuencia cardiaca intra operatoria, grado de hipnosis, grado de nocicepción, necesidad de rescate para hipnosis y analgesia, tiempo de recuperación anestésica, analgesia posoperatoria y efectos adversos. Resultados: Entre los grupos fueron similares la edad, el sexo, el peso, estado físico y tipo de intervención quirúrgica. La frecuencia cardiaca no mostró diferencias entre los grupos. En relación a la tensión arterial mediapos-incisión, fue mayor en el grupo control con diferencias significativas (p=0,03). La necesidad de rescate intraoperatorio para la hipnosis y analgesia fue significativamente mayor en el grupo control. Con respecto a la recuperación anestésica, analgesia posoperatoria y efectos adversos no hubo diferencias significativas. Conclusiones: La combinación ketofol resultó segura y efectiva para proveer una adecuada anestesia en procedimientos quirúrgicos mínimamente invasivos con tiempos quirúrgicos menores a 30 min. La concentración de 1:4 brindó mejor estabilidad hemodinámica, adecuada hipnosis y analgesia intraoperatoria, con menor incidencia de efectos adversos(AU)
Introduction: In recent years, a special interest has appeared in the ketamine/propofol combination for patients intervened by minimally invasive procedures. Objective: To evaluate the effectiveness and safety of total intravenous anesthesia with ketofol at 1:4 concentration versus 1:2 concentration in patients undergoing minimally invasive surgery. Methods: An analytical, quasiexperimental, prospective and longitudinal study was carried out at General Calixto García University Hospital, between December 2019 and December 2020, with thirty patients divided into two groups of fifteen patients each: study group (SG; ketofol 1:4) and control group (CG; ketofol 1:2). The following aspects were analyzed: mean blood pressure and intraoperative cardiac frequency, degree of hypnosis, degree of nociception, necessity of rescue for hypnosis and analgesia, anesthetic recovery time, postoperative analgesia and adverse effects. Results: Age, sex, weight, physical condition and type of surgery were similar between groups. Heart rate showed no differences between groups. Mean blood pressure after incision was higher in the control group, with significant differences (P=0.03). The necessity of intraoperative rescue for hypnosis and analgesia was significantly higher in the control group. Regarding anesthetic recovery, postoperative analgesia and adverse effects, there were no significant differences. Conclusion: The ketofol combination was safe and effective for providing adequate anesthesia in minimally invasive surgical procedures with surgical times of less than thirty minutes. The 1:4 concentration provided better hemodynamic stability, adequate hypnosis and intraoperative analgesia, with lower incidence of adverse effects(AU)

BACKGROUND: The bispectral index parameter is used to guide the titration of general anesthesia; however, many studies have shown conflicting results regarding the benefits of bispectral index monitoring. The objective of this systematic review with meta-analysis is to evaluate the clinical impact of monitoring with the bispectral index parameter. METHODS: The search for evidence in scientific information sources was conducted during December 2013 to January 2015, the following primary databases: Medline/PubMed, LILACS, Cochrane, CINAHL, Ovid, SCOPUS and TESES. The criteria for inclusion in the study were randomized controlled trials, comparing general anesthesia monitored, with bispectral index parameter with anesthesia guided solely by clinical parameters, and patients aged over 18 years. The criteria for exclusion were studies involving anesthesia or sedation for diagnostic procedures, and intraoperative wake-up test for surgery of the spine. RESULTS: The use of monitoring with the bispectral index has shown benefits reducing time to extubation, orientation in time and place, and discharge from both the operating room and post anesthetic care unit. The risk of nausea and vomiting after surgery was reduced by 12% in patients monitored with bispectral index. Occurred a reduction of 3% in the risk of cognitive impairment postoperatively at 3 months postoperatively and 6% reduction in the risk of postoperative delirium in patients monitored with bispectral index. Furthermore, the risk of intraoperative memory has been reduced by 1%. CONCLUSION: Clinically, anesthesia monitoring with the BIS can be justified because it allows advantages from reducing the recovery time after waking, mainly by reducing the administration of general anesthetics as well as the risk of adverse events.

RESUMO
Abstract Introduction: Healthcare costs are increasing against the backdrop of scarce resources. Surgical procedures are an important part of healthcare spending, and the cost of anesthetic techniques is relevant as part of the total cost of care and it is a potential target for expenditure optimization. Although important economic differences have been reported internationally for general anesthesia options, there are no publications in Colombia that compare current costs and allow for informed and financially responsible decision-making. Objective: To quantify and compare direct costs associated with the various general anesthesia options most frequently used at the present time. Methods: Cost minimization analysis based on a theoretical model of balanced general anesthesia using isoflurane, sevoflurane, desflurane in combination with remifentanil, and TIVA (propofol and remifentanil). Initial results were obtained using a deterministic simulation method and a sensitivity analysis was performed using a Monte Carlo simulation. Results: The average total cost per case for the different anesthetic techniques was COP 126381 for sevoflurane, COP 97706 for isoflurane, COP 288605 for desflurane and COP 222 960 for TIVA. Conclusions: Balanced general anesthesia with desflurane is the most costly alternative, 1.2 times more expensive than TIVA, and 2 and 3 times more costly than balanced anesthesia with sevoflurane and isoflurane, respectively. TIVA ranks second with a cost 1.8 times higher than balanced anesthesia with sevoflurane and 2.5 times higher than balanced anesthesia with isoflurane.
Resumen Introducción: Los costos de la atención en salud son crecientes y se enfrentan a un escenario de recursos escasos. La realización de procedimientos quirúrgicos hace parte importante de la atención y del gasto en salud, el costo de las técnicas anestésicas utilizadas es relevante en el costo total de la atención y es un objetivo potencial para la optimización del gasto. Aunque a escala internacional se han reportado diferencias económicas importantes entre las alternativas para anestesia general, en Colombia no se cuenta con publicaciones que comparen los costos actuales y permitan una toma de decisiones informada y responsable económicamente. Objetivo: Cuantificar y comparar los costos directos para Colombia de las diferentes alternativas para anestesia general usadas con más frecuencia en la actualidad. Métodos: Análisis de minimización de costos basado en un modelo teórico de anestesia general balanceada con isoflurano, sevoflurano, desflurano en combinación con remifentanilo y TIVA (propofol y remifentanilo). Se obtuvieron resultados iniciales utilizando una simulación con un método determinista y se realizó un análisis de sensibilidad con una simulación de Montecarlo. Resultados: El costo total promedio por caso para las diferentes técnicas anestésicas fue de COP 126.381 para sevoflurano, COP 97.706 para isoflurano, COP 288.605 para desflurano y COP 222.960 para TIVA. Conclusiones: La anestesia general balanceada con desflurano es la alternativa de mayor costo, es 1,2 veces más costosa que la TIVA, y 2 y 3 veces más que la balanceada con sevoflurano e isoflurano, respectivamente. La TIVA ocupa el segundo lugar con un costo 1,8 veces superior a la balanceada con sevoflurano y 2,5 veces a la balanceada con isoflurano.

Resumo Justificativa: Náusea e Vômito no Pós-Operatório (NVPO) é uma complicação multifatorial com etiologia não esclarecida. A técnica anestésica, as características dos pacientes e o tipo de cirurgia são considerados fatores que afetam a NVPO. O presente estudo foi desenhado para comparar o efeito da anestesia inalatória com anestesia intravenosa na incidência e gravidade de NVPO na cirurgia abdominal. Método: Foi realizado estudo clínico mono-cego prospectivo randomizado com 105 pacientes com idades de 18 − 65 anos. Os pacientes foram divididos em dois grupos, Anestesia Total Intravenosa (TIVA) e anestesia inalatória. A incidência e gravidade de NVPO foram avaliadas em cinco momentos: 0, 2, 6, 12 e 24 horas pós-cirurgia. O uso de antiemético de resgate também foi avaliado. Resultados: NVPO ocorreu em 50,9% dos pacientes no grupo inalatória e 17,3% dos pacientes no grupo TIVA (p< 0,001). A incidência de vômitos relatados foi 11,3% no grupo Inalatória e 3,8% no grupo TIVA (p = 0,15). Necessitaram de medicação antiemética 24,5% dos pacientes no grupo Inalatória e 9,6% dos pacientes no grupo TIVA (p = 0.043). Conclusão: A incidência de náusea e vômito no pós-operatório, a necessidade de administração de droga antiemética de resgate e a gravidade da náusea foram significantemente mais baixas no grupo TIVA.

Introducción. En el proceso de envejecimiento, la mayoría de los sistemas orgánicos mantienen su funcionamiento basal, pero existe una reducción de la reserva funcional y de la capacidad para compensar el estrés fisiológico, lo que hace que los pacientes de mayor edad sean más propensos a complicaciones postoperatorias. Se realizó un estudio en instituciones de Bucaramanga para determinar la incidencia de déficit cognitivo postoperatorio y los factores de riesgo asociados. Metodología. Estudio observacional analítico de cohorte prospectivo realizado en instituciones de salud de Bucaramanga durante 2017 con pacientes mayores de 55 años intervenidos bajo anestesia regional, general balanceada o anestesia total intravenosa. Resultados. Se estudiaron 173 pacientes, 112 mujeres (64.74%) y 61 hombres (35.26%) operados. Las técnicas anestésicas más empleadas fueron: Regional (46.24%) y General balanceada (44.51%). La incidencia de Déficit Cognitivo Postoperatorio a corto plazo fue 6.36% en pacientes previamente sanos, con valor P significativo (0.001) ajustado. Se detectó deterioro cognitivo del 51.41% con alteraciones en los dominios de lenguaje, atención y memoria; con aumento en la evaluación a largo plazo. Durante el seguimiento de pacientes a largo plazo resultó en un 11.55%, determinando la incidencia de Déficit Cognitivo Postoperatorio tardío en un 17.91%. La técnica anestésica con mayor proporción de déficit a largo plazo fue la anestesia mixta, comparada con anestesia regional. Discusión. En la actualidad no existe una definición estandarizada de Déficit Cognitivo Postoperatorio, se ha observado mayor frecuencia y mayor prolongación en pacientes de edad avanzada. El estudio demostró una incidencia temprana significativamente menor, comparándolo con artículos internacionales, pero una incidencia mayor en déficit postoperatorio tardío, resultado de mayores complicaciones intraoperatorias, comparado con otros estudios. Conclusiones. El Déficit Cognitivo Postoperatorio involucra múltiples factores de riesgo; en el estudio se encontró mayor asociación con la edad, la escolaridad, la hipotensión y la anestesia general. No hubo asociación entre comorbilidades y el Déficit Cognitivo Postoperatorio. Se determinó la presencia de hipotensión para desarrollo de este déficit.

Introduction. Within the aging process, most organic systems maintain their basal functions. However, there is a reduction in functional reserve and the capacity to compensate physiological stress, which makes older patients more prone to postoperative complications. A study was performed in institutions in Bucaramanga to determine the incidence of postoperative cognitive dysfunction and the associated risk factors. Methodology. This was a analytical observational prospective cohort study performed in healthcare institutions in Bucaramanga in 2017 with patients older than 55 years of age under regional, balanced general or total intravenous anesthesia. Results. One hundred and seventy-three operated patients were studied, among which 112 (64.74%) were women and 61 (35.26%) were men. The most commonly used anesthetic techniques were: regional (46.24%) and balanced general (44.51%). Short-term Postoperative Cognitive Dysfunction incidence was 6.36% in previously healthy patients, with an adjusted significant P value (0.001). Cognitive deterioration was detected in 51.41% of patients, with alterations in their mastery of language, attention and memory. This increased for the long-term evaluation. During long-term patient follow-up, it resulted in 11.55%, determining the incidence of delayed Postoperative Cognitive Dysfunction at 17.91%. The anesthetic technique with the highest proportion of long- term dysfunction was mixed anesthesia, compared to regional anesthesia. Discussion. There is currently no standardized definition for Postoperative Cognitive Dysfunction. It has been observed more frequently and for longer extensions in older patients. The study demonstrated a significantly lower early incidence when compared to international articles, but a greater incidence of delayed postoperative dysfunction as a result of more intraoperative complications compared to other studies. Conclusions. Postoperative Cognitive Dysfunction involves multiple risk factors. The study observed a greater association with age, level of education, hypotension and general anesthesia. There was no association between comorbidities and Postoperative Cognitive Dysfunction. The presence of hypotension was determined for developing this dysfunction.

Introdução. No processo de envelhecimento, a maioria dos sistemas orgânicos mantém seu funcionamento basal, mas há uma diminuição da reserva funcional e da capacidade de compensar o estresse fisiológico que torna os pacientes idosos mais sujeitos a complicações pós-operatórias. Foi realizado um estudo em instituições da cidade de Bucaramanga para determinar a incidência de déficit cognitivo pós-operatório e os fatores de risco associados. Métodos. Estudo observacional analítico de coorte prospectivo realizado em instituições de saúde em Bucaramanga durante o ano de 2017 em pacientes com idade superior a 65 anos operados sob anestesia regional, geral balanceada ou anestesia geral intravenosa. Resultados. Foram estudados 173 pacientes, 112 mulheres (64.74%) e 61 homens (35.26%) operados. As técnicas anestésicas mais utilizadas foram: regional (46.24%) e geral balanceada (44.51%). A incidência de déficit cognitivo pós-operatório de curto prazo foi de 6.36% em pacientes previamente saudáveis, com um valor P significativo (0.001) ajustado. Detectou- se deterioração cognitiva de 51.41% com alterações nos domínios da linguagem, atenção e memória; com aumento na avaliação de longo prazo. No seguimento a longo prazo dos pacientes resultou em 11.55%, determinando a incidência de déficit cognitivo pós-operatório tardio em 17.91%. A técnica anestésica com maior proporção de déficit no longo prazo foi a anestesia mista, em comparação com a anestesia regional. Discussão. Atualmente não existe uma definição padronizada de Déficit Cognitivo Pós-operatório, a qual observa-se com maior frequência e por mais tempo em pacientes idosos. O estudo demonstrou incidência precoce significativamente menor, em comparação com resultados de artigos internacionais, mas maior incidência de déficit pós-operatório tardio, resultado de maiores complicações intraoperatórias, em comparação com outros estudos. Conclusões. O Déficit Cognitivo Pós-operatório envolve múltiplos fatores de risco; o estudo encontrou maior associação com idade, escolaridade, hipotensão e anestesia geral. Não houve associação entre comorbidades e Déficit Cognitivo Pós-operatório. Determinou-se a presença de hipotensão para o desenvolvimento desse déficit.

RESUMEN Introducción: la anestesia general libre de opioides surge ante la necesidad de evasión del uso de opioides en el transoperatorio y sus efectos indeseados en el posoperatorio. Objetivo: evaluar el comportamiento hemodinámico y la recuperación anestésica en pacientes intervenidas mediante cirugía ambulatoria por cáncer de mama, en las cuales se administró anestesia general total intravenosa libre de opioides o general balanceada. Métodos: se realizó un estudio cuasiexperimental, prospectivo en pacientes a las que se aplicó anestesia general balanceada (n=34) y total intravenosa libre de opioides (n=34) intervenidas quirúrgicamente por cáncer de mama, en el Hospital General Docente "Abel Santamaría Cuadrado", durante el 2018. Resultados: el grupo de anestesia general balanceada mostró mayor variación intraoperatoria de los parámetros evaluados, con diferencias significativas (p=0,019). El tiempo medio de despertar fue menor en el grupo de anestesia total intravenosa (2,10 ± 0,907 min vs 5,35 ± 1,250 min; p<0,01), al igual que el dolor, con diferencia significativa (p<0,05) y el tiempo de recuperación, donde una hora después de la intervención, el 85 % cumplía los criterios de alta anestésica. El retraso en el alta de la unidad de recuperación ocurrió principalmente por el bajo nivel de actividad motora, con mayor incidencia en el grupo de anestesia general balanceada (71 % vs 26 %; p=0,00). Conclusiones: la anestesia total intravenosa libre de opioides fue superior al método general balanceado, pues mostró mayor estabilidad hemodinámica y analgesia, menor incidencia de complicaciones posoperatorias y menor tiempo de estancia en sala de recuperación posanestésica.
ABSTRACT Introduction: opioid-free general anesthesia arises from the need to avoid the use of opioids in the transoperative period and the undesirable effects in the postoperative period. Objective: to assess the hemodynamic behavior and anesthetic recovery in patients who underwent ambulatory surgery for breast cancer and those who were given either opioid-free intravenous general or balanced general anesthesia. Methods: a quasi-experimental, prospective study was carried out on patients who received balanced general anesthesia (n=34) and total opioid-free intravenous anesthesia (n=34), who underwent breast cancer surgery at Abel Santamaria Cuadrado General Teaching Hospital during 2018. Results: the group of balanced general anesthesia showed greater intraoperative variation of the parameters assessed, with significant differences (p=0.019). The mean time of awakening was lower in the intravenous total anesthesia group (2.10 ± 0,907 min vs. 5,35 ± 1,250 min; p<0.01), as was pain, with significant difference (p<0.05) and the recovery time, where one hour after the surgery, 85 % met the criteria for anesthesia discharge. The delay in discharge from the recovery unit occurred mainly because of the low level of motor activity, with a higher incidence in the group of balanced general anesthesia (71% vs. 26 %; p=0.00). Conclusions: intravenous opioid-free total anesthesia was higher to the balanced general approach because it showed greater hemodynamic and analgesic stability, lower incidence of postoperative complications, and shorter time spent in the post-anesthesia recovery room.
RESUMO
OBJECTIVE: Determine the best propofol pharmacokinetic model that meets patient requirements and is devoid of major haemodynamic side effects. MATERIAL AND METHODS: Prospective, randomised, open-label, clinical trial was performed on an intention to treat basis. It included 280 patients with ASA physical status i-iii, aged 18 to 80 years and weight range between 45 to 100kg, scheduled for surgery under general anaesthesia. They were randomized into 2 groups according to the pharmacokinetic model: Modified Marsh group and Schnider group. The haemodynamic changes that occurred during the induction and intubation were analysed. A propofol target controlled infusion was started to achieve and maintain a bispectral index value between 35 and 55. At minute 6, orotracheal intubation was performed and the study finished at minute 11. Heart rate, mean arterial pressure and their product (HR×MAP) were measured and recorded every minute throughout the study. Every HR×MAP value was compared to its baseline value to determine the minimum value before intubation, the maximum value after intubation, the maximum variation after intubation, and its final value. The GRADIENTE (MIN, MAX) variable (primary endpoint of this study) analyses the difference between maximal and minimal values related to intubation. Propofol doses and calculated concentrations and any hypotensive events were also recorded. RESULTS: No differences were found between groups regarding haemodynamic performance. GRADIENTE (MIN, MAX) values and the percentage of hypotensive events were: Modified Marsh group median 77.41% vs. Schnider group 84.86% (p= 0.821) and 17.3% vs. 12.8% (p = 0.292), respectively. CONCLUSION: The study failed to demonstrate any haemodynamic difference between the 2 groups, even though the Modified Marsh group received a larger dose of propofol.

This study aimed to evaluate comparatively the effects of propofol or isoflurane on hemodynamic variables in piglets that received inspired oxygen fraction (FIO2) of 0.5 under spontaneous ventilation. Therefore, sixteen piglets weighing 16±1.1kg, were randomly divided into two groups: GI (Isoflurane and FIO2 of 0.5) and GP (Propofol and FIO2 of 0.5). Heart rate (HR), systolic, diastolic and mean arterial pressure (SAP, DAP and MAP), central venous pressure (CVP), cardiac output (CO), mean pulmonary arterial pressure (mPAP) and mean capillary pulmonary pressure (mCPP) were assessed 40 minutes after anesthetic induction (T0), followed by 15 minutes intervals (from T15 to T60). The variables cardiac index (CI), stroke volume (SV), stroke index (SI), total peripheral resistance (TPR), total peripheral resistance index (TPRI), pulmonary vascular resistance (PVR), and pulmonary vascular resistance index (PVRI) were calculated. SAP and TPRI were significantly different between groups at T30 and T60 (P< 0.05) with higher GP values being recorded. There were no differences in the other variables, however, GP presented mean closer to normality on most of the analyzed variables. Therefore, we conclude that total intravenous anesthesia with propofol presented greater stability of the hemodynamic variables evaluated.(AU)
O objetivo deste estudo foi avaliar comparativamente os efeitos do propofol ou do isoflurano sobre as variáveis hemodinâmicas em leitões que receberam fração inspirada de oxigênio (FIO2) de 0,5 sob ventilação espontânea. Dezesseis leitões, pesando 16±1,1kg, foram divididos aleatoriamente em dois grupos: GI (isoflurano e FIO2 de 0,5) e GP (propofol e FIO2 de 0,5). A frequência cardíaca (FC), a pressão arterial sistólica, a diastólica e a média (PAS, PAD e PAM), a pressão venosa central (PVC), o débito cardíaco (DC),a pressão média da artéria pulmonar (PAPm) e a pressão média capilar pulmonar (PCPm) foram avaliados 40 minutos após a indução anestésica (T0), seguida por intervalos de 15 minutos (de T15 a T60). As variáveis índice cardíaco (IC), volume sistólico (VS), índice sistólico (SI), resistência periférica total (RPT), índice de resistência periférica total (IRPT), resistência vascular pulmonar (RVP) e índice de resistência vascular pulmonar (IRVP) foram calculadas. PAS e IRPT foram significativamente diferentes entre os grupos em T30 e T60 (P<0,05) com maiores valores de GP sendo registrados. Não houve diferenças nas demais variáveis, entretanto o GP apresentou médias próximas da normalidade na maioria das variáveis analisadas. Portanto, concluiu-se que a anestesia intravenosa total com propofol apresentou maior estabilidade das variáveis hemodinâmicas avaliadas.(AU)

Abstract Background Postoperative pain represents an important concern when remifentanil is used for total intravenous anesthesia because of its ultrashort half-life. Longer acting opioids, such as sufentanil, have been used during induction of remifentanil-based total intravenous anesthesia as a means to overcome this shortcoming. However, the effectiveness and safety of such strategy still lacks evidence from randomized clinical trials. Hence, we aimed to assess the postoperative analgesic efficacy and safety of a single dose of sufentanil administered during the induction of remifentanil-based total intravenous anesthesia. Methods Forty patients, scheduled for elective open abdominal surgery, were randomized to receive remifentanil-based total intravenous anesthesia with or without a single dose of sufentanil upon induction. We assessed the postoperative morphine consumption administered through a patient-controlled analgesia pump. Self-reported pain scores and the occurrence of nausea, vomiting, pruritus, agitation, somnolence and respiratory depression were also assessed up to 2 days after surgery. Results The mean difference between the sufentanil and control groups regarding morphine consumption in the post-anesthetic care unit and at 12, 24 and 48 h after surgery were -7.2 mg (95%CI: -12.5 to -2.1, p < 0.001), -3.9 mg (95%CI: -11.9 to 4.7, p = 0.26), -0.6 mg (95%CI: (-12.7 to 12.7, p = 0.80), and -1.8 mg (95%CI: (-11.6 to 15.6, p = 0.94), respectively. Neither self-reported pain nor the incidence of adverse events were significantly different between groups at any time point. Conclusion Our findings suggest that the administration of sufentanil during induction of remifentanil-based total intravenous anesthesia is associated with decreased early postoperative opioid consumption.
Resumo Justificativa A dor pós-operatória é uma grande preocupação quando o remifentanil é usado para anestesia intravenosa total devido à sua meia-vida ultracurta. Os opioides de ação mais longa, como o sufentanil, têm sido usados durante a indução de anestesia intravenosa total à base de remifentanil como um meio de superar essa deficiência. Porém, a eficácia e segurança de tal estratégia ainda precisam de evidências advindas de ensaios clínicos randômicos. Portanto, objetivamos avaliar a eficácia analgésica e a segurança pós-operatória de uma dose única de sufentanil administrada durante a indução de anestesia intravenosa total à base de remifentanil. Métodos Quarenta pacientes eletivamente agendados para cirurgia abdominal aberta foram randomizados para receber anestesia intravenosa total à base de remifentanil, com ou sem uma dose única de sufentanil, após a indução da anestesia. Avaliamos o consumo de morfina no pós-operatório, administrado através de uma bomba de analgesia controlada pelo paciente. Os escores de dor autorrelatados e a ocorrência de náusea, vômito, prurido, agitação, sonolência e depressão respiratória também foram avaliados até dois dias após a cirurgia. Resultados A diferença média entre os grupos sufentanil e controle em relação ao consumo de morfina em sala de recuperação pós-anestesia e após 12, 24 e 48 horas da cirurgia foi de -7,2 mg (IC 95%: -12,5 a -2,1, p < 0,001), -3,9 mg (IC 95%: -11,9 a 4,7, p = 0,26), -0,6 mg (IC 95%: (-12,7 a 12,7, p = 0,80) e -1,8 mg (IC 95%: -11,6 para 15,6, p = 0,94), respectivamente. Não houve diferença significativa tanto nos escores de dor autorrelatados, quanto na incidência de eventos adversos entre os grupos. Conclusão Nossos achados sugerem que a administração de sufentanil durante a indução de anestesia intravenosa total à base de remifentanil está associada à redução do consumo de opioides no pós-operatório imediato.
