Complicaciones y grado de dificultad de la intubación orotraqueal en la unidad de cuidados intensivos pre-post instauración de un protocolo de intubación para el paciente crítico. Estudio prospectivo y observacional / Complications and degree of difficulty of orotracheal intubation in the intensive care unit before and after the establishment of an intubation protocol for critically ill patients: A prospective, observational study

Objetivo: El objetivo de nuestro estudio fue comparar el grado de dificultad y las complicaciones relacionadas con la intubación orotraqueal en una unidad de cuidados intensivos (UCI), pre y post instauración de un protocolo de intubación basado en la guía de práctica clínica para el manejo de la vía aérea difícil específica para el paciente crítico, publicada en 2018 por la Difficult Airway Society (Reino Unido). Métodos: Estudio prospectivo, observacional, comparando todas las intubaciones realizadas en nuestra UCI en un periodo pre-protocolo (enero 2015-enero 2019) con un periodo post-protocolo (febrero 2019-julio 2022). Durante el procedimiento se registró el material utilizado para la intubación, el grado de dificultad de la intubación y las complicaciones asociadas. Resultados: Durante el periodo de estudio fueron intubados 661 pacientes: 437 en el periodo pre-protocolo (laringoscopia directa 96%) y 224 en el post-protocolo (laringoscopia directa 53%, videolaringoscopio 46%). En el periodo post-protocolo observamos una mejoría de la visión laringoscópica en comparación con el pre-protocolo (Cormack-Lehane ≥2b en el 7,6% vs 29,8%, p<0,001), y una disminución de las intubaciones calificadas de dificultad moderada-severa (6,7% vs 17,4%, p<0,001). La intubación al primer intento fue del 92,8% en el periodo post-protocolo frente al 90,2% pre-protocolo (p=0,508). No encontramos diferencias significativas en las complicaciones en los dos periodos estudiados. Conclusiones: Las intubaciones realizadas en el periodo post-protocolo se han asociado a una mejoría de la visión laringoscópica y a una menor dificultad de intubación en comparación con el periodo pre-protocolo.(AU)

Objective: The objective of our study was to compare the degree of difficulty and complications related to tracheal intubation in an intensive care unit (ICU) before and after the introduction of an intubation protocol based on the Difficult Airway Society guidelines for the management of tracheal intubation in critically ill adults, published in 2018. Methods: Prospective, observational study comparing all intubations performed in our ICU over two periods: pre-protocol (January 2015-January 2019) and post-protocol (February 2019-July 2022). The material used for intubation, the degree of difficulty, and intubation-related complications were recorded. Results: During the study period, 661 patients were intubated —437 in the pre-protocol period (96% by direct laryngoscopy) and 224 in the post-protocol period (53% with direct laryngoscopy, 46% with video laryngoscopy). We observed an improvement in laryngeal view in the post-protocol period compared to the pre-protocol period (Cormack-Lehane ≥2b in 7.6% vs 29.8%, P<.001), and a decrease in the number of moderate-to-severely difficult intubations (6.7% vs 17.4%, P<.001). The first-pass success rate was 92.8% in the post-protocol period compared to 90.2% pre-protocol (P=.508). We did not find significant differences in complications between the periods studied. Conclusions: Intubations performed in the post-protocol period were associated with improved laryngeal view and fewer cases of difficult intubation compared with the pre-protocol period.(AU)

Inusual endocarditis infecciosa sobre válvula protésica por Pseudomonas monteilii y Acinetobacter nosocomialis con fatal desenlace / Unusual infective prosthetic valve endocarditis due to Pseudomonas monteilii and Acinetobacter nosocomialis with a fatal result

Presentamos el caso de una endocarditis por Pseudomonas monteilii y Acinetobacter nosocomialis con un fatal desenlace. El paciente tenía una historia reciente de reemplazo valvular aórtico. La ecografía transesofágica y la tomografía computarizada confirmaron la presencia de vegetación en la válvula protésica y un seudoaneurisma aórtico con un absceso en la raíz aórtica. El cultivo de la válvula demostró P.monteilii y A.nosocomialis. El paciente fue tratado con cirugía y antibióticos, pero sufrió un deterioro y murió 44días tras la cirugía. En nuestro conocimiento este es el primer caso de endocarditis producida por P.monteilii y A.nosocomialis publicado en la literatura. Estas bacterias han sido descritas como contaminantes ambientales; sin embargo, deben ser consideradas como potenciales patógenos, en especial en pacientes con válvulas protésicas

We report a case of Pseudomonas monteilii and Acinetobacter nosocomialis endocarditis with a fatal outcome in a patient with a recent history of prosthetic aortic valve replacement. Transesophageal echocardiography and computed tomography confirmed the presence of vegetation on the prosthetic valve and aortic pseudoaneurism with an aortic root abscess. Valve cultures yielded P.monteilii and A.nosocomialis. The patient underwent surgery and received antibiotics, but his condition deteriorated and he died 44days after surgery. To our knowledge, this is the first case of P.monteilii and A.nosocomialis endocarditis reported in the literature. These organisms have been described as environmental contaminants; however, they must be considered potential pathogens, particularly in patients with prosthetic valves

Evaluación de la escala modificada de Cormack-Lehane para visión laringoscópica durante la intubación orotraqueal en una unidad de cuidados críticos. Estudio prospectivo observacional / Evaluation of the laryngoscopy view using the modified Cormack-Lehane scale during tracheal intubation in an intensive care unit. A prospective observational study

Antecedentes y objetivos: La intubación orotraqueal en las unidades de cuidados críticos está asociada a una frecuencia alta de dificultad y complicaciones. Una mala visión glótica durante la laringoscopia directa podría ser la causa. El objetivo de este estudio es evaluar si existe una relación entre la visión laringoscópica valorada por la escala modificada de Cormack-Lehane y la dificultad de intubación y la aparición de complicaciones. Métodos: Se incluyeron todos los pacientes intubados con laringoscopia directa en la Unidad de Cuidados Críticos durante un periodo de 45 meses. En todos los pacientes se valoró la visión glótica medida con la escala modificada de Cormack-Lehane, la dificultad de intubación (intubación al primer intento, dificultad valorada por el anestesiólogo, uso de la guía de Frova) y la aparición de complicaciones (hipotensión, hipoxia, intubación esofágica). Resultados: Se incluyeron 360 pacientes. A medida que aumentó el grado en la escala modificada de Cormack-Lehane, disminuyó la incidencia de intubación orotraqueal al primer intento (1: 97%, 2a: 94%, 2b: 80%, 3: 60%, 4: 0%, p<0,001), aumentó la incidencia de intubación con dificultad moderada o severa (1: 2%, 2a: 4%, 2b: 36%, 3: 77%, 4: 100%, p<0,001), así como la necesidad de uso de Frova (1: 7%, 2a: 8%, 2b: 45%, 3: 60%, 4: 100%, p<0,001). A medida que aumentó el grado en la escala modificada de Cormack-Lehane, aumentó la aparición de hipoxia<90% (1: 20%, 2a: 20%, 2b: 28%, 3: 47%, 4: 100%, p=0,0073) y la hipoxia<80% (1: 11%, 2a: 10%, 2b: 12%, 3: 27%, 4: 100%, p=0,00398). No encontramos relación entre la aparición de hipotensión y el grado en la escala modificada de Cormack-Lehane (p=ns). Conclusiones: Durante la intubación orotraqueal en la Unidad de Cuidados Críticos hemos encontrado una estrecha relación entre una mala visión glótica valorada por la escala modificada de Cormack-Lehane y una mayor dificultad de la técnica. La incidencia de hipoxia se relaciona directamente con un mayor grado en la escala modificada de Cormack-Lehane. No hemos encontrado ninguna relación entre la hipotensión y la escala modificada de Cormack-Lehane

Background and objectvies: Tracheal intubation in the Intensive Care Unit is associated with a high incidence of difficult intubation and complications. This may be due to a poor view of the glottis during direct laryngoscopy. The aim of this study is to determine if there is a relationship between laryngoscopy view using the modified Cormack-Lehane scale with the incidence of difficult intubation and complications. Methods: All patients who were subjected to tracheal intubated with direct laryngoscopy in the Intensive Care Unit over a 45 month period were included in the study. In all patients, an evaluation was made of the laryngoscopy view using the modified Cormack-Lehane scale, as well as the technical difficulty (number of intubations at first attempt, operator-reported difficulty, need for a Frova introducer), and the incidence of complications (hypotension, hypoxia, oesophageal intubation). Results: A total of 360 patients were included. When the grade of the modified Cormack-Lehane scale was increased from 1 to 4, the incidence of first success rate intubation decreased (1: 97%, 2a: 94%, 2b: 80%, 3: 60%, 4: 0%, p<.001), the incidence of moderate and severe difficulty intubation increased (1: 2%, 2a: 4%, 2b: 36%, 3: 77%, 4: 100%, p<.001.), as well as the need for a Frova guide (1: 7%, 2a: 8%, 2b: 45%, 3: 60%, 4: 100%, p<.001). When the grade of the modified Cormack-Lehane scale increased from 1 to 4, the incidence of hypoxia<90% increased (1: 20%, 2a: 20%, 2b: 28%, 3: 47%, 4: 100%, p=.0073), as well as hypoxia<80% (1: 11%, 2a: 10%, 2b: 12%, 3: 27%, 4: 100%, p=.00398). No relationship was observed between the incidence of hypotension and the grade of the modified Cormack-Lehane scale (p=ns). Conclusions: During tracheal intubation in the Intensive Care Unit a close relationship was found between a poor laryngoscopy view using the modified Cormack-Lehane scale and a higher difficulty technique of intubation. A relationship was found between the incidence of hypoxia with a higher grade in the modified Cormack-Lehane scale. No relationship was found between hypotension and the modified Cormack-Lehane scale
