ABSTRACT
The McGrath video laryngoscope is a new airway management device. It is similar to the Macintosh laryngoscope but incorporates a blade at a 60 degrees angle and a camera that sends an image to a color display screen connected to the handle. The device, which requires use of an anti-fog substance and an introducer to guide the angled blade, has been reported to aid in the management of difficult airways. We present 3 cases of difficult oral-tracheal intubation managed with the McGrath video laryngoscope and a Frova intubating introducer. Advantages of this introducer are that it offers the possibility of administering oxygen or changing the size of the endotracheal tube if the first choice proves inappropriate. We discuss whether or not tests to predict difficult airways are applicable when the McGrath video laryngoscope is being used, given that it is not necessary to align the axes of the 3 airways. We conclude it may be useful to combine the McGrath video laryngoscope and the Frova introducer to manage difficult airways.

El videolaringoscopio de McGrath es un nuevo dispositivopara el tratamiento de la vía aérea, se asemeja aun laringoscopio de Macintosh pero incorpora una palacon una angulación de 60º y un sistema óptico conectadoa una pantalla en color que va unida al mango del videolaringoscopio.Requiere de la utilización de una sustanciaantivaho y de una guía que permita vencer el ángulode la pala. En la literatura se ha descrito su uso enpacientes con criterios de dificultad en el manejo de lavía aérea. Presentamos tres casos de intubación orotraquealdifícil que fueron intubados con el videolaringoscopiode McGrath y un introductor de Frova para laintubación. La utilización de este tipo de guía aporta unaserie de ventajas como la posibilidad de administraciónde oxígeno a través de la misma o la posibilidad de cambiarel tamaño del tubo endotraqueal si no hemos elegidoel adecuado. Discutimos la idoneidad de las pruebaspredictoras de intubación orotraqueal difícil debido a lano necesidad de alineación de los tres ejes cuando se utilizael videolaringoscopio de McGrath. Concluimos quela combinación de videolaringoscopio de McGrath yguía Frova puede ser una buena opción para el manejode la vía aérea difícil(AU)

La vía intranasal es una vía de administración transmucosaque aporta como ventajas la facilidad de administración,es incruenta, bien aceptada por el paciente ycarece de efecto de primer paso hepático. La mucosanasal supone una superficie extensa muy vascularizadarecubierta por epitelio ciliar pseudoestratificado, secretorade moco sometido a un movimiento mucociliar quepuede determinar el tiempo de contacto entre los fármacosy la superficie. Los factores que influyen en la absorciónson de tipo anatómico, fisiológico y otros relacionadoscon las propiedades del fármaco y los sistemas deadministración.Revisamos los artículos publicados sobre el uso de fentanilo,meperidina, diamorfina y butorfanol utilizadospor vía intranasal para el tratamiento del dolor agudo.Los efectos adversos sistémicos son similares a los descritospara la vía intravenosa, siendo los más frecuentessomnolencia, náuseas y vómitos. En cuanto a los efectosadversos locales, se ha descrito sensación de quemazóncon meperidina y mal sabor
Intranasal drug administration is an easy, well-tolerated,noninvasive transmucosal route that avoids first-passmetabolism in the liver. The nasal mucosa provides anextensive, highly vascularized surface of pseudostratifiedciliated epithelium. It secretes mucus that is subjected tomucociliary movement that can affect the time of contactbetween the drug and the surface. Absorption is influencedby anatomical and physiological factors as well as byproperties of the drug and the delivery system.We review the literature on intranasal administrationof fentanyl, meperidine, diamorphine, and butorphanolto treat acute pain. The adverse systemic effects aresimilar to those described for intravenousadministration, the most common being drowsiness,nausea, and vomiting. Local effects reported are aburning sensation with meperidine and a bad taste

INTRODUCTION: This trial assessed the safety and efficacy of a continuous posterior tibial nerve block in the ankle provided in the patient's home by elastomeric pump infusion of 0.375% ropivacaine after ambulatory hallux valgus surgery. MATERIAL AND METHODS: Patients were randomized to 2 groups of 20 each to receive either the conventional oral analgesia prescribed by our team after outpatient surgery (metamizole 575 mg/6 h p.o.) or perineural analgesia with a continuous infusion of 5 mL x h(-1) of 0.375% ropivacaine in the posterior tibial nerve. Surgery was performed under hyperbaric spinal anesthesia with mepivacaine and an injection of 0.25% bupivacaine into the joint. Both groups also received 50 mg/8 h p.o. of tramadol as rescue analgesia. Assessment during visits by the home care team 12, 24, and 48 hours after surgery included the following variables: pain on a visual analog scale (VAS, 0-10), sleep quality, need for rescue analgesia, acceptance of the technique, side effects and adverse events. Descriptive statistics were calculated and comparisons were performed with the Mann-Whitney U test; sleep quality and need for rescue analgesia were compared by applying the chi2 statistic with a test of linear trend. RESULTS: The perineural analgesia group had significantly lower VAS scores at 4, 12, and 24 hours and less need for rescue analgesia. No differences in sleep quality were found (P0.07). The incidence of side effects did not differ, and there were no readmissions. The patients expressed a high level of acceptance of the technique. CONCLUSION: Continuous perineural analgesia in the home setting was found to be effective and safe in our patients.

Tramadol es un fármaco analgésico con un doble mecanismo de acción, que actúa sobre los receptores opioides e inhibe la recaptación de monoaminas. Se ha demostrado su eficacia por diversas vías de administración y es ampliamente utilizado. Sus principales vías metabólicas son la O-desmetilación que da lugar a un metabolito activo M1 y la N-desmetilación. Debido a que en su metabolismo están implicadas varias isoformas del citocromo P-450, tramadol está sometido a una serie de interacciones farmacológicas con fármacos de uso corriente como ondansetrón o metoclopramida. Está indicado en el tratamiento del dolor agudo. Se ha administrado también en el manejo de diversoso tipos de dolor crónica, en anestesia y en otras indicaciones poco conocidas (patología neurológica, psiquiétrica, etc.). Está indicado en el tratamiento del dolor agudo postoperatorio en adultos y en otras formas de dolor agudo. Se ha administrado también en el manejo de diversos tipos de dolor crónico, en anestesia y en otras indicaciones poco conocidas (patología neurológica, psiquiétrica, etc.). La utilización de tramadol se acompaña de una serie de efectos adversos siendo los más frecuentes las naúseas, los vómitos y la sensación de mareo. Aunque hay algún caso de dependencia, se trata de un fármaco muy seguro. No se ha descrito ninguna muerte atribuible a tramadol
Tramadol is an analgesic with a double-action mechanisms. It act on µ opioid receptors and inhibits noradrenalina and serotonine re-uptake. Its efficiency has been demonstrated with different methods of administration. Its principal metabolic pathways are O-desmethylation which produces an active metabolite called M1 and N-desmethylation. Because various P-450 cytochrome isoforms are implicated in its metabolism, tramadol undergoes a series of pharmacological interactions with current drugs as ondasetron or metoclopramide. Tramadol is indicated in the treatment of acute postoperative pain in adults and also other forms of acute pain. It has also been used in the management of different types of chronic pain, in anaesthesia and other lesser known indications (neurological pathology, psychiatric, etc). Tramadol has several side-effects such as nausea, vomiting and dizzines. Although there have been some reports about dependency on the drug, it is believe to be quite safe. No death have been attribuded to tramadol use

Ropivacaine is a local anesthetic frequently used to provide regional blocks because its toxicity threshold is favorable and it is highly selective for sensory nerve fibers. Few reports of adverse events and complications related to use of ropivacaine have been published. We report 2 cases of central nervous system toxicity. Each occurred after a brachial plexus block with 0.75% ropivacaine, one performed by an axillary approach and one by an infraclavicular approach with nerve stimulation.
