Manejo de PICC en el Servicio de Urgencias de un hospital universitario / Use of PICC at the University Hospital Emergency Unit

Para gestionar el capital venoso del paciente con seguridad y responsabilidad es necesario aumentar la calidad de los cuidados proporcionados, unificando y estandarizando los criterios de actuación, basándose siempre en la mejor evidencia científica. Las enfermeras de los Servicios de Urgencias deben aplicar la evidencia en el manejo del catéter venoso central de inserción periférica (PICC), conocer el protocolo aprobado por la Dirección Asistencial de su hospital y, sobre todo, evitar la variabilidad en la actuación, que podría aumentar los riesgos relacionados con la atención sanitaria, así como la desconfianza del paciente. Mantener actualizados los conocimientos y promover la adquisición de habilidades en la práctica clínica es de suma importancia para garantizar cuidados de calidad en el manejo de este tipo de catéteres, debiéndose comprobar periódicamente el grado de cumplimiento de la evidencia recogida en los protocolos existentes en el hospital. Las enfermeras tienen el reto de estar al día en el manejo de los accesos vasculares, y deben responder con seriedad y evidencia a los cuidados que necesitan los pacientes a los que se atienden. En este manuscrito se objetiva la necesidad de formar y capacitar de forma continua a los profesionales para el manejo adecuado del PICC. (AU)

In order to manage the venous resource of the patient safely and with responsibility, it is necessary to increase the quality of care provided, unifying and standardizing performance criteria, always based on the best scientific evidence. Emergency Unit nurses must apply evidence in their use of the peripherally inserted central venous catheter (PICC), they must know the protocol approved by the Patient Care Management in their hospital and, most of all, must avoid variability of action, which could increase the risks associated with healthcare as well as mistrust by patients. It is extremely important to keep an updated knowledge and to promote the acquisition of clinical practice skills, in order to guarantee quality care in the use of this type of catheters; the level of compliance of the evidence collected in the hospital protocols must be confirmed periodically. Nurses face the challenge of being updated in the management of vascular accesses, and must give response with seriousness and evidence to the care needed by their patients. This manuscript sets out objectively the need for continuous training and qualification for professionals regarding the adequate use of PICC. (AU)

Seno cavernoso: anatomía, histología y terminología.

BACKGROUND: Although the cavernous sinus (CS) has been studied since 1695, its anatomy and name are still under discussion. METHOD: Anatomy and histology of 40 CS from human cadavers were studied, included both from a newborn specimen. RESULTS: Two walls limit the CS, an inferior medial one composed only of the dura's outer layer and a superior lateral one consisting of both dura's layers. Sinusoidal veins pass through the lateral wall of the CS as a transition between venous tributaries and the CS. An endothelial layer covers the inner surface of the CS and the outer surface of the internal carotid artery. The space within the CS shows trabeculae, which are rarer in adults compared to the newborn. The loss of trabeculae in the CS may be a natural process along with life. CONCLUSIONS: In conclusion, the CS is a real sinus, and the term "cavernous sinus" is appropriately applied.

ANTECEDENTES: Si bien el seno cavernoso (SC) ha sido estudiado desde 1695, su anatomía y nombre aún están bajo discusión. MÉTODOS: Se estudiaron la anatomía y la histología de 40 SC de cadáveres humanos, incluyendo los dos de un recién nacido. RESULTADOS: El SC está limitado por dos paredes, una inferomedial compuesta solo por la capa más externa de la duramadre y otra superolateral compuesta por ambas capas de la duramadre. Hay venas sinusoidales que atraviesan la pared lateral del SC formando una transición entre venas tributarias y el SC. Una capa endotelial recubre la superficie interna del SC y la superficie externa de la arteria carótida interna. El espacio dentro del SC presenta trabéculas, las cuales son escasas en el adulto en comparación con el recién nacido. La pérdida de trabéculas en el SC puede ser un proceso natural a lo largo de la vida. CONCLUSIONES: En conclusión, el SC es un verdadero seno, por lo que el término «seno cavernoso¼ se aplica de forma correcta.

Difficult intravenous access in a paediatric intensive care unit.

INTRODUCTION: Multiple attempts during peripheral cannulation can have major consequences for patients, relatives, and healthcare professionals, therefore we set out to determine the extent of this problem in a paediatric intensive care unit (PICU). OBJECTIVES: The main aim was to describe peripheral venous catheter (PVC) and peripherally inserted central catheter (PICC) cannulation in children in the PICU. Secondary objectives were to determine the success rate of the first cannulation attempt, to quantify patients with difficult venous access (DVA), and to explore the association between DVA and sociodemographic, technique and nursing-related characteristics. METHOD: A cross-sectional descriptive study. Consecutive sampling was used to recruit patients aged 0-18 years admitted to the PICU who required peripheral venous cannulation. An ad hoc questionnaire was used for this purpose, including the presence of DVA as an independent variable. RESULTS: A total of 163 venous cannulations were reported. A total of 55.8% (91) were performed in patients under 1 year of age. Of these, 38.7% (63) were successful on the first attempt and 36.8% (60) had DVA. When there was DVA, 85% (51) of patients had complications, median time to cannulation by short CVP was 30 minutes [15-53] and 2 or more nurses were required on 80% (48) of occasions. CONCLUSIONS: We found a low success rate at first attempt and a high proportion of DVA. More nurses and time were employed during cannulation and complications increased if the patient had DVA. A statistically significant association was found between DVA and age, weight, poor perfusion, veins that were neither visible nor palpable, DIVA score ≥ 4, history of difficult intravenous access, complications, number of nurses and time spent.

Vía venosa difícil en una unidad de cuidados intensivos pediátricos / Difficult intravenous access in a paediatric intensive care unit

Introducción: Los múltiples intentos durante la canalización periférica pueden producir importantes consecuencias que afectan a pacientes, familiares y profesionales, por ello se planteó la necesidad de conocer la dimensión de este problema en una unidad de cuidados intensivos pediátricos (UCIP).Objetivos: El objetivo principal fue describir la canalización de catéter venoso periférico y catéter central de inserción periférica en niños de UCIP. Como objetivos secundarios se propuso determinar la proporción de éxito en el primer intento de canalización, cuantificar los pacientes que presentan vía venosa difícil (VVD), así como explorar la asociación entre la aparición de la VVD y las características sociodemográficas, las relativas a la técnica y a las enfermeras.Método: Estudio descriptivo transversal. Mediante muestreo consecutivo se reclutaron pacientes entre 0 y 18 años ingresados en UCIP que precisaron canalización de acceso venoso periférico. Para ello se utilizó un cuestionario ad hoc incluyendo la presencia de VVD como variable independiente.Resultados: Se recogieron 163 canalizaciones venosas. El 55,8% (91) se realizaron en pacientes menores de 1 año. El 38,7% (63) acertó en el primer intento y el 36,8% (60) presentaron VVD. Cuando aparecía VVD el 85% (51) de los pacientes tuvieron complicaciones, la mediana de tiempo para la canalización mediante catéter venoso periférico corto fue de 30minutos [15-53] y se precisaron 2 o más enfermeras en el 80% (48) de las ocasiones.Conclusiones: Se encontró un bajo porcentaje de acierto al primer intento y una proporción elevada de VVD. Aparecía un mayor número de enfermeras y de tiempo empleado durante la canalización y un aumento de las complicaciones si el paciente presentaba VVD. Se encontró asociación estadísticamente significativa entre VVD y edad, peso, mala perfusión, vena no visible ni palpable, puntuación en la escala DIVA≥4, historia de VVD, complicaciones, número de enfermeras y tiempo empleado.

Effect of intraoperative intravenous lidocaine on pain and plasma interleukin-6 in patients undergoing hysterectomy / Efeito da lidocaína venosa intraoperatória sobre dor e interleucina-6 plasmática em pacientes submetidas a histerectomia / Efecto de la lidocaína venosa intraoperatoria sobre el dolor e interleucina-6 plasmática en pacientes sometidas a histerectomía

BACKGROUND AND OBJECTIVES: Interleukin-6 is a predictor of trauma severity. The purpose of this study was to evaluate the effect of intravenous lidocaine on pain severity and plasma interleukin-6 after hysterectomy. METHOD: A prospective, randomized, comparative, double-blind study with 40 patients, aged 18-60 years. G1 received lidocaine (2 mg kg-1 h-1) or G2 received 0.9% saline solution during the operation. Anesthesia was induced with O2/isoflurane. Pain severity (T0: awake and 6, 12, 18 and 24 h), first analgesic request, and dose of morphine in 24 h were evaluated. Interleukin-6 was measured before starting surgery (T0), 5 h after the start (T5), and 24 h after the end of surgery (T24). RESULTS: There was no difference in pain severity between groups. There was a decrease in pain severity between T0 and other measurement times in G1. Time to first supplementation was greater in G2 (76.0 ± 104.4 min) than in G1 (26.7 ± 23.3 min). There was no difference in supplemental dose of morphine between G1 (23.5 ± 12.6 mg) and G2 (18.7 ± 11.3 mg). There were increased concentrations of IL-6 in both groups from T0 to T5 and T24. There was no difference in IL-6 dosage between groups. Lidocaine concentration was 856.5 ± 364.1 ng mL-1 in T5 and 30.1 ± 14.2 ng mL-1 in T24. CONCLUSION: Intravenous lidocaine (2 mg kg-1 h-1) did not reduce pain severity and plasma levels of IL-6 in patients undergoing abdominal hysterectomy. .

JUSTIFICATIVA E OBJETIVOS: A interleucina-6 (IL-6) é preditora de intensidade no trauma. O objetivo deste estudo foi avaliar o efeito da lidocaína por via venosa sobre a intensidade da dor e IL-6 após histerectomia. MÉTODO: O estudo foi prospectivo, randomizado, comparativo e duplo-encoberto em 40 pacientes, entre 18 e 60 anos. Foi administrada lidocaína (2 mg.kg-1.h-1) no G1 ou solução salina a 0,9% no G2 durante a operação. A anestesia foi com O2/isoflurano. Foi avaliada a intensidade da dor (T0: despertar e seis, 12, 18 e 24 horas), a primeira solicitação de analgésico, a dose de morfina nas 24 horas. A IL-6 foi medida antes do início da operação (T0), após cinco horas do início (T5) e 24 horas após o término (T24). RESULTADOS: Não houve diferença na intensidade da dor entre os grupos. Ocorreu diminuição da intensidade da dor entre T0 e os outros momentos avaliados no G1. O tempo para primeira complementação foi maior no G2 (76,0 ± 104,4 min) do que no G1 (26,7 ± 23,3 min). Não houve diferença na dose de morfina complementar entre G1 (23,5 ± 12,6 mg) e G2 (18,7 ± 11,3 mg). Houve aumento das concentrações de IL-6 em ambos os grupos de T0 para T5 e T24. Não houve diferença na dosagem de IL-6 entre os grupos. A concentração de lidocaína foi 856,5 ± 364,1 ng.mL-1 em T5 e 30,1 ± 14,2 ng.mL-1 em T24. CONCLUSÃO: A lidocaína (2 mg.kg-1.h-1) por via venosa não promoveu redução da intensidade da dor e dos níveis plasmáticos de IL-6 em pacientes submetidas a histerectomia abdominal. .
