INTRODUCCIÓN Y OBJETIVO: Sugammadex es una ɣ-ciclodextrina modificada hidrosoluble cuyo mecanismo de acción es antagonizar el bloqueo neuromuscular inducido por rocuronio mediante la encapsulación de las moléculas de este agente en el plasma originando un complejo sugammadex-rocuronio. Este complejo es filtrado a la orina por el glomérulo en función del filtrado glomerular y se excreta de forma inalterada sin ser metabolizado. En los pacientes con insuficiencia renal se modifican las características farmacocinéticas de estos fármacos, de tal manera que al administrar sugammadex en estos pacientes, el complejo sugammadex-rocuronio se filtra por el riñón en función del filtrado glomerular disminuido de ese paciente, y por tanto está más tiempo circulando por el torrente circulatorio, aumentando las probabilidades de efectos secundarios, hasta que es eliminado. El intervalo QT coincide en el tiempo con la sístole ventricular, tanto del periodo de despolarización como de repolarización. El alargamiento de este segmento está relacionado con la aparición de torsade de pointes, la cual puede provocar síncope, fibrilación ventricular y, en la quinta parte de los casos, muerte súbita. Nuestro objetivo fue estudiar si la administración de sugammadex a dosis de 4 mg/kg aumenta el intervalo QTc ≥ 10 ms respecto al basal en pacientes con y sin alteración de la función renal. MÉTODO: Estudio cuasiexperimental tipo pre-post, prospectivo, consecutivo y multicéntrico. Se seleccionaron tres grupos de pacientes. Un grupo con función renal normal, un grupo con enfermedad renal leve o moderada y otro grupo con enfermedad renal terminal. La técnica anestésica realizada fue premedicación con midazolam y fentanilo, inducción y mantenimiento con propofol, remifentanilo y rocuronio. Mediante un dispositivo Holter se registró el electrocardiograma durante los 120 minutos posteriores a la administración de sugammadex. También se recogieron los datos de relajación muscular mediante el “train of four”, presión arterial media, frecuencia cardiaca, saturación de 02 y diuresis. RESULTADOS: Encontramos que el intervalo QTc no aumenta de manera significativa respecto al basal tras la administración de sugammadex, ya sea al analizar la población total como al analizar la población por subgrupos de acuerdo a su función renal. Encontramos que el intervalo QTc es mayor en las mujeres y en los pacientes que tienen alteración de la función renal terminal. CONCLUSIÓN: Sugammadex no aumenta el intervalo QTc ≥ 10 ms respecto al basal en pacientes con o sin insuficiencia renal, Sugammadex is a modified hidrosoluble gammadextrine which acts antagonizing the neuromuscular blockade induced by rocuronium encapsulating the molecules of this agent in plasma bringing about a rocuronium-sugammadex complex. This complex is filtered to the urine according to the glomerular filtering function and is excreted in an unaltered form without being metabolized. In patients with renal failure, the pharmacokinetic characteristics of these drugs are modified, in such way that while administering sugammadex in patients with renal failure the complex rocuronium-sugammadex is filtered through the kidney according to a decreased glomerular filtering function and thus, is circulating longer in the blood stream increasing the likelihood of secondary effects until their complete elimination. The QT interval coincides in time with the ventricular systolic contraction, comprising both the despolarization and the repolarization periods. The lengthening of this interval is related to the apparition of the Torsade de Pointes, which can cause syncope, ventricular fibrillation and eventually, in a fifth part of the cases, sudden death. Our objective in this study was to prove whether the administration of sugammadex, at a 4mg/kg doses lengthens the QT interval 10 ms or more respect to the basal interval in normal patients and in those with different degrees of renal failure. METHOD: This is a multicentre, observational, prospective, consecutive study of coupled data. Three groups of patients were established. First, a group with a normal renal function; second, a group with mild or moderate renal failure; and third, a group with end-stage renal failure. The anesthetic technique was started with a premedication with midazolam and fentanyl, and induced and maintained with propofol, remifentanil and rocuronium. By means of a Holter device, an electrocardiogram register was carried out over the 120 minutes following the sugammadex administration. Muscle relaxation index “Train of four” registers were also recorded as well as mean blood pressure, heartbeat rate, pulsioxymetry and diuresis. RESULTS: We find that the QTc interval does not increase significantly, compared to the previous basal interval, after the administration of sugammadex, either in the total population or in each one of the different subgroups according to their renal function. We did find that the QTc interval is longer in women and in patients with an altered renal function. We found that there is an inverse correlation between the QTc interval and the renal clearance. CONCLUSION: Sugammadex does not increase the QTc interval for 10 ms or more as compared to the basal interval in patients with or without renal failure.

El objetivo general del estudio es determinar la capacidad del dispositivo TOF-Cuff (manguito de presión modificado, que incluye electrodos de estimulación) de monitorizar con el mismo dispositivo la presión arterial no invasiva (PANI) y el nivel de bloqueo neuromuscular (BNM) inducido farmacológicamente, mediante estimulación del plexo braquial a nivel humeral y registro de los cambios de presión evocados. Se establecieron como objetivos específicos: 1. Comparar y validar los valores obtenidos de relajación neuromuscular con TOF-Cuff con los obtenidos con mecanomiografía (MMG) (método control) durante la fase de recuperación del BNM, cuando se alcanza TOF-ratio> 0.9 y >0.7 respectivamente (variable principal). 2. Comparar y validar las medidas obtenidas con el dispositivo TOF-Cuff con las medidas de presión arterial invasiva a nivel de la arteria radial. 3. Verificar que la utilización del TOF-Cuff no produce lesiones ni efectos secundarios sobre el paciente. METODOLOGÍA: Ensayo clínico, unicéntrico, abierto y controlado, con 32 pacientes adultos programados para cirugía electiva bajo anestesia general en posición decúbito supino, con una duración prevista mínima de 30 minutos, para la validación de la monitorización neuromuscular, y estudio adicional consecutivo al anterior con 17 pacientes para la validación de la monitorización de la PANI. Ambos se llevaron a cabo en el Hospital General Universitario Santa Lucía de Cartagena, entre octubre de 2013 y marzo de 2014. Los criterios de inclusión fueron: edad 18 a 65 años, ASA I-III y firma de consentimiento informado. Se excluyeron pacientes con enfermedades concomitantes, factores predictores de vía aérea difícil, tratamiento con fármacos que alteren la transmisión neuromuscular, y mujeres en edad fértil. Para la monitorización del BNM se colocó el manguito TOF-Cuff con los electrodos a nivel humeral, y el MMG en el brazo contra lateral. Se realizó la estimulación simultánea con los 2 métodos según el siguiente patrón: durante 1 minuto estímulos simples a una frecuencia de 1 Hz, seguido de calibración automática y estimulación TOF cada 20 segundos el resto de la intervención. Al finalizar la cirugía se revirtió el BNM con neostigmina 0.05 mg•kg-1 o sugammadex 2 mg•kg-1 de forma alternativa, y se extubó a los pacientes cuando se alcanzó un TOF-ratio > 0.9. Para la monitorización de la presión arterial (PA) se colocó un catéter intra-arterial a nivel de la arteria radial en el brazo contra lateral al TOF-Cuff, y se realizaron mediciones cada 5 minutos registrando: PA sistólica, PA diastólica, PA media y frecuencia cardiaca, con un mínimo de 10 pares de medidas por paciente. Todos los datos fueron exportados a un PC en tiempo real, y se analizaron con el método de Bland-Altman. CONCLUSIONES: 1.- Un TOF-ratio>0.9 cuantificado mediante el dispositivo TOF-Cuff tiene una buena correlación con un TOF-ratio>0.7 en la MMG, por lo que puede emplearse con seguridad en la práctica clínica de igual modo que se utiliza la aceleromiografía, aunque ambos no sean intercambiables con la MMG, ya que la recuperación del BNM medida con TOF-Cuff sufre un adelanto respecto a la MMG. 2.- El fácil manejo y accesibilidad del dispositivo TOF-Cuff pueden contribuir a una mayor difusión de la monitorización neuromuscular cuantitativa rutinaria. 3.- La utilización del dispositivo TOF-Cuff como parte de la monitorización estándar en quirófano puede contribuir a la seguridad del paciente, reduciendo el riesgo de bloqueo residual. 4.- Ningún paciente presentó acontecimientos adversos, lesiones a nivel de la piel o dolor residual. 5.- El dispositivo TOF-Cuff es válido para la medición de la PANI., The overall objective of the study is to determine the ability of TOF-Cuff device (blood-pressure modified cuff, including stimulation electrodes) to monitor with the same device the non-invasive blood pressure (NIBP) and the depth of a neuromuscular blockade (NMB) induced pharmacologically, by stimulation of the brachial plexus at the humeral level and recording evoked changes in pressure. We have established the following objectives: 1. To compare and validate the values obtained from neuromuscular relaxation TOF-Cuff with those obtained by mechanomyography (MMG) (control method) during the recovery phase of BNM, when a TOF ratio > 0.9 and > 0.7 (primary endpoint) were reached respectively. 2. To compare and validate the measurements obtained with TOF-Cuff device versus invasive blood pressure registered at the radial artery. 3. To verify that the use of TOF-Cuff does not injure or causes side effects on any patient. METHODOLOGY: Clinical, single-centre, open-controlled study with 32 adult patients for scheduled elective surgery under general anesthesia in supine position, with an expected duration of 30 minutes minimum, for the validation of neuromuscular monitoring, and an additional consecutive study of 17 patients for validation of NIBP monitoring. Both were held in the University General Hospital Santa Lucía of Cartagena, between October 2013 and March 2014. Inclusion criteria were: age 18-65 years old, ASA I- III and with an informed consent signed. Patients with comorbidities, predictors of a difficult airway, under treatment with drugs affecting neuromuscular transmission and women of childbearing age were excluded. For monitoring NMB, the TOF-Cuff device was place with electrodes at humeral level and the MMG on the opposite arm. A simultaneous stimulation with the 2 methods was performed according to the following pattern: single frequency of 1 Hz, automatic calibration followed TOF stimulation every 20 seconds for the rest of the intervention. When the surgical procedure had ended, the NMB was reversed with neostigmine 0.05 mg•kg-1 or sugammadex 2 mg•kg-1 alternatively, and patients were extubated when a TOF ratio > 0.9 was reached. For monitoring the blood pressure (BP) an intra-arterial catheter at the radial artery was placed in the opposite arm to TOF-Cuff, and measurements were performed every 5 minutes recording: systolic BP, diastolic BP, mean arterial pressure and heart rate, with at least 10 pairs of measurements per patient. All data were exported to a PC in real time, and analyzed using the Bland- Altman method. CONCLUSIONS: 1. A TOF-ratio > 0.9 quantified by TOF-Cuff device has a good correlation with a TOF ratio > 0.7 in MMG, so it can be safely used in clinical practice just as acceleromyography is used at present, although both are not interchangeable with MMG, because recovery of BNM measured TOF-Cuff suffers an advance regarding the MMG. 2. The ease of use and accessibility of TO -Cuff device can contribute to a wider dissemination of routine quantitative neuromuscular monitoring. 3. The use of TOF-Cuff device as part of the standard surgical monitoring can contribute to the patient’s safety by reducing the risk of a residual block. 4. No patient had any skin lesions, residual pain or any other side effects. 5. The TOF-Cuff device is valid for NIBP measurement.

Introducción La obesidad mórbida se asocia con manejo difícil de la vía aérea. No existiendo común acuerdo en que estos pacientes sean difíciles de intubar pero si existe en que son difíciles de ventilar con máscara facial, por lo que es prioritario el control rápido de su vía aérea. Ello ha motivado la búsqueda de factores predictores y técnicas para tratar de disminuir los riesgos en esta población. El laringoscopio óptico Airtraq®, es un dispositivo descartable con hoja anatómica que permite una intubación sin alineación de los ejes oro-faringo-laríngeo, un mayor campo de visión, curva de aprendizaje corta, y no requiere aplicación de fuerza para exponer la glotis. Esta tesis se planteó para evaluar si el laringoscopio óptico Airtraq® permite un manejo más rápido de la vía aérea que el laringoscopio de Macintosh en el paciente obeso mórbido. Se compara con el laringoscopio Macintosh por ser este el laringoscopio estándar para el manejo de la vía aérea. Objetivos Comparar la rapidez de la intubación traqueal del laringoscopio de Macintosh versus el laringoscopio óptico Airtraq® y el éxito de la misma en la población obesa mórbida en cirugía programada. Comparar la visión de la glotis con ambos laringoscopios. Comparar la respuesta hemodinámica al uso de ambos dispositivos y las complicaciones derivadas de su empleo. Material y métodos Estudio prospectivo, observacional, longitudinal y analítico, realizado en el Hospital General Universitario Santa Lucía, de Cartagena, Murcia. Se incluyeron 46 pacientes obesos mórbidos, mayores de 18 años, ASA III, programados para cirugía electiva, que fueron asignados en forma aleatorizada para ser intubados con el laringoscopio Macintosh (n=23) o el dispositivo óptico Airtraq® (n=23), manejados con la misma técnica anestésica e intubados por la investigadora. Se comparó: el tiempo de intubación, la visión laríngea, la necesidad de maniobras adicionales para realizar la intubación traqueal, el éxito de la maniobra, las complicaciones y la respuesta hemodinámica. Resultados Las características preoperatorias de los pacientes estudiados fueron similares en ambos grupos. El tiempo promedio de la intubación fue 17,27 ±16,1 seg y 22,11 ± 13,62 seg en los grupos Airtraq® y Macintosh respectivamente (p 0,279). Con el dispositivo Airtraq® el 95,65% de pacientes presentaron una visión glótica 1 y 2a (p=0,006) y fueron necesarias menos maniobras de optimización para realizar la intubación traqueal (p=0,001). No se presentaron casos de intubación difícil, fallida ni ventilación difícil. Se detectó un aumento de la frecuencia cardiaca estadísticamente significativo con el empleo del laringoscopio Macintosh. Un paciente con epiglotis redundante no pudo ser intubado con el laringoscopio óptico Airtraq®. Conclusiones En este estudio, ambos dispositivos permitieron un manejo rápido y seguro de la vía aérea. El empleo del laringoscopio Airtraq® permite una mejor visión glótica y ello reduce las maniobras adicionales para realizar la intubación traqueal y se detecta un menor estímulo simpático evidenciado por un menor aumento de la frecuencia cardiaca posterior a la intubación traqueal. La epiglotis redundante se muestra como un posible factor limitante para el éxito de la intubación con el laringoscopio óptico Airtraq®., Introduction Morbid obesity is associated with difficult handling of the airway. No agreement exists that these patients are difficult to intubate but if they are difficult to ventilate with facial mask, so it is a priority the fast control of their airway. This has motivated the search of predictors and handling techniques to try to reduce the risks in this population. The Airtraq® optic laryngoscope is a disposable device with anatomic blade that permits an intubation without alienation of the oral, pharyngeal and laryngeal axes, a larger field of vision, a short learning curve and it does not requires application of force to expose the glottis. This thesis was set to evaluate if the Airtraq® optic laryngoscope allows a faster handling of the air track that the Macintosh laryngoscope in the morbid obesity patient. It compares to the Macintosh laryngoscope for being this the standard laryngoscope for the airway handling. Objectives Compare the quickness of the tracheal intubation of the Macintosh laryngoscope versus the Airtraq® optic laryngoscope and the success of both in the morbid obesity population in programmed surgery. Compare the vision of the glottis with both laryngoscopes. Compare the hemodynamic answer in the use of both devices and the complications derived from its use. Materials and methods Prospective, observational, longitudinal and analytic study, realized in the Santa Lucia Universitary General Hospital, from Cartagena, Murcia. It included 46 morbid obesity patients, older than 18 years, ASA III, programmed for elective surgery, that were assigned in random patterns for being intubated with the Macintosh Laryngoscope (n=23) or the Airtraq® optical device (n=23), operated with the same anaesthetic technique and intubated for the researcher. It was compared: the time of the intubation, the laryngeal vision, the necessity of additional manoeuvres to realize the tracheal intubation, the success of the manoeuvres, the complications and the hemodynamic answer. Results The pre-operatory characteristics of the studied patients were similar in both groups. The average time of the intubation was 17,27 ± 16,1 seg and 22,11 ± 13,62 seg in the Airtraq® and Macintosh groups respectively (p 0,279). With the Airtraq® device the 95,65% of patients presented a glottic view 1 and 2a (p=0,006) and less optimizing manoeuvres were needed to realize the tracheal intubation (p=0,001). There were not presented any difficult intubation, failed intubation, or difficult ventilation cases. It was detected a raise in the cardiac frequency statistically significant with the use of the Macintosh laryngoscope. A patient with redundant epiglottis couldn’t be intubated with the Airtraq® optic laryngoscope. Conclusions In this study, both devices permitted a quick handling and security of the airway. The use of the Airtraq® laryngoscope permits a better glottic view and that reduces the additional manoeuvres to realize the tracheal intubation and detects a minor adrenergic stimulus proved by a minor rise in the posterior cardiac frequency to the tracheal intubation. The redundant epiglottis it is shown as a possible limiting factor for the success of the intubation with the Airtraq® optic laryngoscope.

- Abstract
Background and Objectives: We compare the inspiratory and expiratory regional lung densities between different levels of COPD severity (as assessed by the GOLD scale and by the BODE index), and to assess the relationship between regional lung densities and functional lung parameters., Patients and Methods: Fifty-five stable moderate-severe COPD men were selected. Functional evaluation included dyspnoea scale, blood gases, spirometry, plethysmography, diffusing capacity and six-minute walk test. Severity was classified according the GOLD scale and the BODE index. High resolution computed tomography (HRCT) scans of the entire lung at full inspiration and two sections at full expiration were obtained. Densitometry software was used to calculate the densities of the lung areas., Results: Inspiratory and expiratory mean lung densities (MLD) of the lower lobes were significantly lower in very severe and severe COPD patients than in moderate patients. In contrast, we only found differences between the upper lobe MLD values of moderate and severe COPD patients. Inspiratory and expiratory HRCT densities were similar among all BODE quartiles, for both the upper and lower lobes. In a multiple regression analysis, airway obstruction parameters were mainly related to the expiratory MLD of the lower lobes, whereas lung hyperinflation parameters were predicted by the inspiratory MLD of the lower lobes. Lastly, diffusion capacity was independently related to the expiratory/inspiratory MLD of the lower lobes and to the inspiratory MLD of the upper lobes., Conclusions: There are differences in lung attenuation measurements by HRCT between the varying levels of COPD severity as assessed by the GOLD scale., (Copyright 2009 SEPAR.

- Abstract
Objective: The purpose of this study was to assess the agreement between different measurements of mean daily physical activity taken over a week in chronic obstructive pulmonary disease (COPD) patients with an accelerometer and to analyze the medium-term repeatability of these measurements., Patients and Methods: The study enrolled 12 healthy control subjects and 23 patients with stable COPD (mean [SD] forced expiratory volume in 1 second [FEV1] of 45% [13%] of predicted and a ratio of FEV1 to forced vital capacity of 53% [13%]). Accelerometer output, measured in vector magnitude units, was recorded in a physical activity log for a 1-week period. The results were then analyzed to compare output for a conventional recording period (Friday to Sunday) to that for 2 other periods (Monday to Wednesday and Tuesday to Thursday). The measurements were repeated 3 to 5 weeks later., Results: Activity counts were lower in the COPD patients than in the control subjects (184 [99] vs 314 [75]; P < .001). In the COPD patients, the results for the Friday to Sunday period correlated well with the results for both the Monday to Wednesday period (95% confidence interval, -29.21 to 28.81) and the Tuesday to Thursday period (95% confidence interval, -32.13 to 28.43). There were no significant differences in terms of medium-term repeatability of accelerometer readings between the COPD group and the control group (repeatability coefficient of 11.2% [4.6%] and 8.5% [4.7%], respectively)., Conclusions: Both agreement between the different measurements of physical activity taken during a 1-week period and medium-term repeatability for COPD patients and control subjects were very good.
