Traqueotomía percutánea por dilatación con el método Ciaglia Blue Dolphin® / Percutaneous tracheostomy through dilatation with the Ciaglia Blue Dolphin® method

Objetivo Describir las complicaciones perioperatorias y posoperatorias en una cohorte de pacientes críticos traqueotomizados con la técnica Ciaglia Blue Dolphin®. Diseño Estudio observacional, prospectivo, de cohorte. Ámbito Dos unidades de cuidados intensivos polivalentes. Pacientes Adultos sometidos a ventilación mecánica prolongada. Intervención Traqueotomía percutánea mediante Ciaglia Blue Dolphin® con control fibrobroncoscópico. Variables Se registraron variables demográficas, complicaciones intraoperatorias y posoperatorias, así como mortalidad en la Unidad de Cuidados Intensivos e intrahospitalaria. Resultados Se incluyeron 70 pacientes. Edad: 68,6±12 años (68,6% hombres). APACHE II: 23,5±8,7. El tiempo en ventilación mecánica previo a la traqueotomía percutánea fue de 14,3±5,5 días. Se registró algún tipo de complicación perioperatoria en 25 pacientes. En 23 fueron leves: dificultad para introducir la cánula (n=10), sangrado leve (n=7), atelectasia parcial (n=3), perforación del balón del tubo orotraqueal (n=2) e imposibilidad técnica para la finalización de la técnica con cambio a Ciaglia Blue Rhino® (n=1). En 2 pacientes se produjeron complicaciones graves: hemorragia grave que obligó a finalizar el procedimiento mediante técnica quirúrgica (n=1) y falsa vía más desaturación (n=1). En ningún caso hubo riesgo vital y en 11 casos se produjeron en curva de aprendizaje. Como complicaciones posoperatorias solo se observó sangrado pericánula leve en 2 enfermos. Conclusiones La Ciaglia Blue Dolphin® con guía endoscópica es una técnica segura. Como en otros procedimientos, la curva de aprendizaje contribuye a un incremento en la incidencia de complicaciones. Sus potenciales beneficios con respecto a otras modalidades de traqueotomía percutánea deberán evaluarse en estudios aleatorizados (AU)

Objective To describe the perioperative and postoperative complications in critically ill patients requiring percutaneous tracheostomy using the Ciaglia Blue Dolphin® technique. Design A prospective, observational, cohort study was carried out. Scope Two medical-surgical Intensive Care Units. Patients Adult patients subjected to prolonged mechanical ventilation. Intervention Percutaneous tracheostomy using Ciaglia Blue Dolphin® with an endoscopic guide. Variables Demographic variables, intraoperative and postoperative complications, and Intensive Care Unit and ward mortality were recorded. Results Seventy patients were included. Age: 68.6±12 years (68.6% males). APACHE II score: 23.5±8.7. Duration of mechanical ventilation prior to percutaneous tracheostomy: 14.3±5.5 days. Perioperative complications were recorded in 25 patients. In 23 of them the complications were mild: difficulty inserting the tracheostomy cannula (n=10), mild bleeding (n=7), partial atelectasis (n=3), cuff leak (n=2), and technical inability to complete the procedure (switch to Ciaglia Blue Rhino®) (n=1). Severe complications were recorded in 2 patients: severe bleeding that forced completion of the procedure via surgical tracheostomy (n=1), and false passage with desaturation (n=1). None of the complications proved life-threatening. Eleven complications occurred in the learning curve. As postoperative complications, mild peri-cannula bleeding was seen in 2 patients. Conclusions Percutaneous tracheostomy using the Ciaglia Blue Dolphin® technique with an endoscopic guide is a safe procedure. As with other procedures, the learning curve contributes to increase the incidence of complications. Potential benefits versus other percutaneous tracheostomy techniques should be explored by randomized trials (AU)

Traqueotomía percutánea en el paciente ventilado / Percutaneous tracheostomy in the ventilated patient

Las indicaciones para la realización de la traqueotomía se pueden resumir en: 1.obstrucción de la vía aérea superior, 2. prevención del daño laríngeo y de la vía aérea alta por intubación prolongada en pacientes sometidos a ventilación mecánica prolongada, y 3.permitir un fácil acceso a la vía aérea para la eliminación de secreciones. Desde 1985 la traqueotomía percutánea (TP) se ha ido consolidando como la técnica para establecer una vía aérea quirúrgica en los pacientes que necesitan ventilación prolongada. Desde entonces, se han publicado diferentes estudios comparativos entre TP y traqueotomía quirúrgica, se han desarrollado nuevas modalidades de TP y el uso de las técnicas por dilatación con control endoscópico continúa extendiendo su popularidad por todo el mundo. La traqueotomía debe realizarse tan pronto como se identifica la necesidad de tener un paciente ventilado de forma prolongada, sin embargo no hay modelos para predecir tal situación y el momento para su realización debe individualizarse. En el presente artículo analizaremos el estado actual de la TP en los pacientes ventilados mecánicamente, considerada para muchos la técnica de elección para la realización de la traqueotomía en el enfermo crítico

The medical indications of tracheostomy comprise the alleviation of upper airway obstruction; the prevention of laryngeal and upper airway damage due to prolonged translaryngeal intubation in patients subjected to prolonged mechanical ventilation; and the facilitation of airway access for the removal of secretions. Since 1985, percutaneous tracheostomy (PT) has gained widespread acceptance as a method for creating a surgical airway in patients requiring long-term mechanical ventilation. Since then, several comparative trials of PT and surgical tracheostomy have been conducted, and new techniques for PT have been developed. The use of percutaneous dilatation techniques under bronchoscopic control are now increasingly popular throughout the world. Tracheostomy should be performed as soon as the need for prolonged intubation is identified. However a validated model for the prediction of prolonged mechanical ventilation is not available, and the timing of tracheostomy should be individualized. The present review analyzes the state of the art of PT in mechanically ventilated patients --- this being regarded by many as the technique of choice in performing tracheostomy in critically ill patients

Pronóstico de los ancianos ventilados mecánicamente en la UCI / Prognosis of elderly patients subjected to mechanical ventilation in the ICU

Objetivo Analizar el pronóstico de los pacientes ancianos ventilados mecánicamente en la Unidad de Cuidados Intensivos (UCI).Diseño y ámbito Análisis secundario de un estudio observacional prospectivo y multicéntrico llevado a cabo durante un periodo de 2 años en 13 UCI españolas. Pacientes Pacientes adultos que precisaron ventilación mecánica (VM) invasiva durante más de 24 horas. Intervencione Ninguna. Variables de interés Datos demográficos, APACHE II, SOFA, motivo de VM, comorbilidad, situación funcional, reintubación, duración de la VM, traqueotomía, mortalidad en la UCI, mortalidad hospitalaria. Resultados Se incluyeron 1.661 pacientes. De ellos 1.127 (67,9%) eran hombres. Edad: 62,1±16,2 años. APACHE II: 20,3±7,5. SOFA total: 8,4±3,5. Cuatrocientos veintitrés pacientes (25,4%) tenían 75 años o más. Los índices de comorbilidad y capacidad funcional fueron peor en este grupo de pacientes (p<0,001 para ambas variables). La mortalidad en la UCI fue superior en este grupo (33,6%) que en los más jóvenes (25,9%) (p=0,002), al igual que la mortalidad hospitalaria (41,8 vs 31,8%; p<0,0001). No hubo diferencias en cuanto a tiempo de VM, incidencia de traqueotomías o índice de reintubaciones. Por causas de VM solo los pacientes ≥ 75 años ventilados por neumonía, sepsis o trauma presentaron una mortalidad en UCI más alta que los menores de esa edad (46,3 vs 33,1% p=0,006; 55 vs 25,8% p=0,002; 63,6 vs 4,5% p<0,001 respectivamente).Conclusiones Los ancianos (≥ 75 años) tienen una mayor mortalidad en UCI y hospitalaria que los más jóvenes sin diferencias en la duración de la VM. Las diferencias son a expensas de patologías como neumonía, sepsis y trauma (AU)

Objective To analyze the prognosis of mechanically ventilated elderly patients in the Intensive Care Unit (ICU).Design and scope Sub-analysis of a prospective multicenter observational cohort study conducted over a period of two years in 13 medical-surgical ICUs in Spain. Patients Adult patients who required mechanical ventilation (MV) for longer than 24hours.InterventionsNone.Study variables Demographic data, APACHE II, SOFA, reason for MV, comorbidity, functional condition, reintubation, duration of MV, tracheotomy, ICU mortality, in-hospital mortality. Results A total of 1661 patients were recruited. Males accounted for 67.9% (n=1127), with a mean age of 62.1±16.2 years. APACHE II: 20.3±7.5. Total SOFA: 8.4±3.5. Four hundred and twenty-three patients (25.4%) were ≥ 75 years of age. Comorbidity and functional condition rates were poorer in these patients (p<0.001 for both variables). Mortality in the ICU was higher in the elderly patients (33.6%) than in the younger subjects (25.9%) (p=0.002). Also, in-hospital mortality was higher in those ≥ 75 years of age. No differences in duration of MV, prevalence of tracheostomy or reintubation incidence were found. Regarding the indication for MV, only the patient ≥ 75 years of age with pneumonia, sepsis or trauma had a higher in-ICU mortality than the younger patients (46.3% vs 33.1%, p=0.006; 55% vs 25.8%, p=0.002; 63.6% vs 4.5%, p<0,001, respectively). No differences were found referred to other reasons for MV. Conclusion Older patients (≥ 75 years) have significantly higher in-ICU and in-hospital mortality than younger patients without differences in the duration of mechanical ventilation. Differences in mortality were at the expense of pneumonia, sepsis and trauma (AU)

Modelo de probabilidad de ventilación mecánica prolongada / Prolonged mechanical ventilation probability model

Objetivo: Diseñar un modelo de probabilidad de ventilación mecánica prolongada (VMP) con variables clínicas obtenidas durante las primeras 24 horas de su instauración. Diseño: Estudio de cohorte, observacional, prospectivo, multicéntrico. Ámbito: Trece UCI españolas polivalentes. Pacientes: Adultos ventilados durante más de 24 horas. Intervenciones: Ninguna. Variables de interés: APACHE II, SOFA, variables clínicas y demográficas, motivo de VM, comorbilidad y estado funcional. Se construyó un modelo de riesgo multivariante en el que la variable dependiente tenía tres posibles estados: 1.- Muerte precoz. 2.- Retirada precoz de la VM. 3.- VMP. Resultados: Se incluyeron 1.661 pacientes. El 67,9% (n=1.127) fueron hombres. Edad: 62,1±16,2 años. APACHE II: 20,3±7,5. SOFA: 8,4±3,5. Las puntuaciones APACHE II y SOFA fueron mayores en pacientes ventilados > 7 días (p=0,04 y p=0,0001 respectivamente). El fracaso de la ventilación no invasiva (VNI) se asoció a VMP (p=0,005). Se generó un modelo de riesgo multivariante con las siguientes variables: APACHE II, SOFA, fracaso de VNI, ubicación hospitalaria antes del ingreso en UCI y motivo de ventilación mecánica. La exactitud del modelo global (..) (AU)

Objective: To design a probability model for prolonged mechanical ventilation (PMV) using variables obtained during the first 24hours of the start of MV. Design: An observational, prospective, multicenter cohort study. Scope: Thirteen Spanish medical-surgical intensive care units. Patients: Adult patients requiring mechanical ventilation for more than 24hours. Interventions: None. Study variables: APACHE II, SOFA, demographic data, clinical data, reason for mechanical ventilation, comorbidity, and functional condition. A multivariate risk model was constructed. The model contemplated a dependent variable with three possible conditions: 1. Early mortality; 2. Early extubation; and 3. PMV. Results: Of the 1661 included patients, 67.9% (n=1127) were men. Age: 62.1±16.2 years. APACHE II: 20.3±7.5. Total SOFA: 8.4±3.5. The APACHE II and SOFA scores were higher in patients ventilated for 7 or more days (p=0.04 and p=0.0001, respectively). Noninvasive ventilation failure was related to PMV (p=0.005). A multivariate model for the three above exposed outcomes was generated. The overall accuracy of the model in the training and validation sample was 0.763 (95%IC: 0.729-0.804) and 0.751 (95%IC: 0.672-0.816), respectively. The likelihood ratios (LRs) for early extubation, involving a cutoff point of 0.65, in the training sample were LR (+): 2.37 (95%CI: 1.77-3.19) and LR (-): 0.47 (95%CI: 0.41-0.55). The LRs for the early mortality model, for a cutoff point of 0.73, in the training sample, were LR (+): 2.64 (95%CI: 2.01-3.4) and LR (-): 0.39 (95%CI: 0.30-0.51). Conclusions: The proposed model could be a helpful tool in decision making. However, because of its moderate accuracy, it should be considered as a first approach, and the results should be corroborated by further studies involving larger samples and the use of standardized criteria (AU)
