Intubación orotraqueal a través de mascarilla laríngea Ambu(R) Auragain(TM) en paciente pediátrico con lipomatosis infiltrante congénita / Endotracheal intubation through laryngeal Ambu(R) Auragain(TM) mask airway mask in paediatric patients affected by congenital infiltrating lipomatosis

Las malformaciones congénitas que afectan a la vía aérea pueden generar problemas para realizar una ventilación efectiva, intubación o incluso ambas, con el consiguiente aumento del riesgo de hipoxemia. Es esencial para el anestesiólogo pediátrico el conocimiento exacto de la anatomía de la vía aérea del paciente, así como una planificación preoperatoria cuidadosa. Cada vez son más los dispositivos diseñados para el control de la vía aérea en el paciente pediátrico. Este caso clínico describe el uso de la mascarilla laríngea de tercera generación (Ambu(R) Auragain(TM)) para la intubación orotraqueal de un paciente pediátrico con vía aérea difícil prevista secundaria a lipomatosis infiltrante congénita en la región facial

Congenital defects that affect paediatric airway could lead to several difficulties for effective ventilation, intubation, or even both, increasing the risk of hypoxaemia. It is essential for the paediatric anaesthesiologist to have accurate knowledge of the anatomy of patient́s airway, as well as judicious preoperative planning. Increasingly, more devices have been designed for the control of difficult airway in the paediatric patient. This case report describes the application of a third-generation laryngeal mask (- Ambu(R) Auragain (TM)) for endotracheal intubation of a child with anticipated difficult airway, secondary to congenital diffuse infiltrating facial lipomatosis

Estudio radiológico para evaluar la difusión de dos volúmenes (10 vs. 20ml) de contraste radiopaco en el bloqueo de las ramas cutáneas de los nervios intercostales en la línea medio axilar (BRILMA) en un modelo experimental porcino / Radiological study to evaluate the spreading of two volumes (10 vs. 20ml) of radiological contrast in the block of cutaneous branches of intercostal nerves in medial axillary line (BRILMA) in a porcine experimental model

Objetivo: Los bloqueos interfasciales de la pared torácica se están desarrollando como alternativa a los bloqueos centrales en la cirugía de mama. Sin embargo, existen escasos estudios que hayan evaluado la extensión anatómica del anestésico local. Nuestro objetivo fue analizar, mediante fluoroscopia, la difusión de dos volúmenes (10 vs. 20ml) de contraste radiopaco (iopamidol) en el bloqueo del plano serrato-intercostal (BRILMA) en un modelo experimental porcino. Material y métodos: Se seleccionaron 10 cerdos de la raza Large-White a los que se realizó un bloqueo BRILMA ecoguiado bilateral, administrando 10 y 20ml de iopamidol en hemitórax izquierdo y derecho, respectivamente. La difusión del contraste se analizó por fluoroscopia. Se utilizó el test de correlación de Spearman para evaluar la relación entre el volumen administrado y la difusión radiológica. Se consideró significativo un valor de p<0,05. Resultados: Se realizaron 20 bloqueos, pudiéndose analizar 18. La administración de 10ml de contraste se asoció con una difusión media de 2,28±0,31 espacios (IC 95%: 2,01-2,54), mientras que la administración de 20ml mostró una difusión de 3±0,25 espacios (IC 95%: 2,81-3,18). Hubo una correlación significativa entre el volumen inyectado y la difusión del contraste (coeficiente de correlación de Spearman de 0,81; p=0,0001). Conclusión: Nuestros resultados demuestran una difusión dependiente del volumen en el bloqueo BRILMA, aunque sin guardar una relación 1:1. Duplicar el volumen ha incrementado en un 31% los segmentos bloqueados. Estos hallazgos, si se corroboran en la práctica clínica, permitirían un ajuste más preciso en el volumen de anestésico administrado

Objective: Interfascial blocks of the thoracic wall are being developed as an alternative to central blocks in breast surgery. However, there are few studies that have evaluated the anatomical extension of the local anaesthetic. The objective of this study was to analyse, using fluoroscopy, the spreading of two volumes (10 vs. 20ml) of radiological contrast in the serratus-intercostal plane block in an experimental pig model. Material: and methods Ten Large-White breed pigs were selected to have a bilateral ultrasound serratus-intercostal plane block performed, with the administering of 10ml and 20ml of iopamidol in the right and left hemithorax, respectively. The spreading of contrast was analysed by fluoroscopy. The Spearman test correlation was used to evaluate the relationship between the administered volume and radiological spreading. A value of P<.05 was considered significant. Results: Twenty anaesthetic blocks were performed, being able to analyse 18 of them. The administration of 10ml of contrast was associated with a mean spreading of 2.28±0.31 (95% CI; 2.01-2.54) intercostal spaces, while the administration of 20ml showed a spreading of 3±0.25 (95% CI; 2.81-3.18) intercostal spaces. There was a significant correlation between the injected volume and the spreading of the contrast (Spearman correlation coefficient of 0.81; P=.0001). Conclusion: The results showed a spreading of volume subject to the serratus-intercostal plane block, although not maintaining a 1:1 ratio. Doubling the volume increased the blocked segments by 31%. These findings, if corroborated in the clinical practice, would allow a more precise adjustment in the anaesthetic volume administered

Introduction: We performed a preliminary study where puncture radiofrequency was evaluated as a new technique, available to treat selected cases of tonsillar hypertrophy. Objectives: The main objective is to determine the benefits and safety of puncture radiofrequency tonsil reduction in pediatric patients. Secondary we evaluated the implications of surgical and anesthetic techniques. Material and methods: Retrospective and descriptive study of all pediatric patients who underwent radiofrequency tonsil hypertrophypuncture during June 2010-February 2011 in our unit. The selected patients were included in a protocol including: age, sex, previous symptoms, airway maintenance device, surgical time, adenoidectomy association, complications, hospital stay, postoperative pain, recovery and outcome. Results: During the reported period 15 children have undergone this technique, nine girls (60%) and six boys (40%), with a mean age of 3.9 years. The most frequent symptoms for surgery were breathing difficulties, snoring and swallowing disorders. In allcases reinforced laryngeal mask was used as the sole device for airway maintenance. Adenoidectomy was associated in 80% of patients. The average time for surgery was 14 minutes. There were neither intraoperative nor postoperative complications. NSAIDs and acetaminophen were used as postoperative analgesia. At home, patients only used acetaminophen for pain control. Hospital stay was less than 24 hours, with 48-72 hours of recovery time. No patient came back to our emergency units. After two months, there was tonsillar reduction demonstrated in 14 of the 15 cases (93%).Conclusions: Puncture Radio frequency tonsils reduction, inpediatric selected cases can be a safe, effective and a low morbidity technique (AU)
