ABSTRACT
@#BACKGROUND: Ischemic stroke refers to a disorder in the blood supply to a local area of brain tissue for various reasons and is characterized by high morbidity, mortality, and disability. Early reperfusion of brain tissue at risk of injury is crucial for the treatment of acute ischemic stroke. The purpose of this study was to evaluate comfort levels in managing acute stroke patients with hypoxemia who required endotracheal intubation after multidisciplinary in situ simulation training and to shorten the door-to-image time. METHODS: This quality improvement project utilized a comprehensive multidisciplinary in situ simulation exercise. A total of 53 participants completed the two-day in situ simulation training. The main outcome was the self-reported comfort levels of participants in managing acute stroke patients with hypoxemia requiring endotracheal intubation before and after simulation training. A 5-point Likert scale was used to measure participant comfort. A paired-sample t-test was used to compare the mean self-reported comfort scores of participants, as well as the endotracheal intubation time and door-to-image time on the first and second days of in situ simulation training. The door-to-image time before and after the training was also recorded. RESULTS: The findings indicated that in situ simulation training could enhance participant comfort when managing acute stroke patients with hypoxemia who required endotracheal intubation and shorten door-to-image time. For the emergency management of hypoxemia or tracheal intubation, the mean post-training self-reported comfort score was significantly higher than the mean pre-training comfort score (hypoxemia: 4.53±0.64 vs. 3.62±0.69, t= -11.046, P<0.001; tracheal intubation: 3.98±0.72 vs. 3.43±0.72, t= -6.940, P<0.001). We also observed a decrease in the tracheal intubation and door-to-image time and a decreasing trend in the door-to-image time, which continued after the training. CONCLUSION: Our study demonstrates that the implementation of in situ simulation training in a clinical environment with a multidisciplinary approach may improve the ability and confidence of stroke team members, optimize the first-aid process, and effectively shorten the door-to-image time of stroke patients with emergency complications.
ABSTRACT
Objectives: This pilot study aimed to identify and test a battery of time-efficient and cost-effective voice and swallowing screening tools for post-extubated patients in Chile. Methods: A panel of four experts selected and rated voice and swallowing screening tools. Seven measures were selected: smoothed cepstral peak prominence (CPPS) and maximum phonation time (MPT) for voice assessment, Volume-Viscosity Swallow Test (V-VST) for swallowing, voluntary and reflex peak cough flow for cough assessment, Eating Assessment Tool-10 (EAT-10), and Vocal Symptom Scale (VoiSS) for patient-reported outcomes. These tools were applied to four post-extubation patients within 48-72 hours post-hospital discharge, alongside the assessment of 17 matched controls. Results: Post-extubation patients showed significantly shorter MPT, lower CPPS values, increased V-VST dysphagia signs, reduced voluntary peak cough flow, and more pronounced symptoms on both the VoiSS and EAT-10 compared to controls. Limitations: The study had a modest sample size and relied solely on clinical screening tools. Value: This pilot study suggests a feasible and cost-effective approach to voice and swallowing screening for post-extubation patients, valuable in resource-constrained settings. Conclusion: While these accessible tools are not gold-standard assessments, they offer valuable insights and can guide future research. This study underscores the potential of selected tools in facilitating early detection of voice and swallowing disorders in post-extubation patients.
Objetivos: Este estudio piloto tuvo como objetivo identificar y probar una batería de herramientas de detección de problemas de voz y deglución que fueran eficientes en cuanto a tiempo y costo para pacientes chilenos postextubados. Métodos: Un panel de cuatro expertos seleccionó y evaluó herramientas de detección de voz y deglución. Se seleccionaron siete medidas: prominencia de pico cepstral suavizado (CPPS) y tiempo máximo de fonación (TMF) para la evaluación de la voz, prueba de volumen-viscosidad (V-VST) para la deglución, flujo máximo voluntario y reflejo de la tos para evaluar la tos, Eating Assessment Tool-10 (EAT-10) y la Escala de Sintomas Vocales (ESV) para los resultados informados por los pacientes. Estas herramientas se aplicaron a cuatro pacientes postextubados (48-72 horas), junto con la evaluación de 17 controles pareados. Resultados: Los pacientes postextubados mostraron un TMF y CPPS significativamente más bajos, aumento de los indicios de disfagia en la V-VST, reducción del flujo máximo de la tos y síntomas más pronunciados tanto en la ESV como en la EAT-10 en comparación con los controles. Limitaciones: El estudio tuvo un tamaño de muestra reducida y se basó únicamente en herramientas de detección clínica. Valor: Este estudio piloto sugiere un enfoque factible y rentable para la detección de problemas de voz y deglución en pacientes postextubados, valioso en entornos con recursos limitados. Conclusión: Aunque ese abordaje no sustituye a las evaluaciones de referencia, ofrece información valiosa y puede guiar futuras investigaciones que busquen facilitar la detección temprana de los trastornos de la voz-deglución en pacientes postextubados.
ABSTRACT
Resumen ANTECEDENTES: Las mujeres embarazadas e infectadas con SARS-CoV-2 tuvieron 2.9 veces más probabilidad de requerir ventilación invasiva. La colecistitis aguda es la segunda indicación quirúrgica más común en el embarazo. En la búsqueda bibliográfica no se encontraron reportes de concomitancia de ambas enfermedades durante el embarazo, por este motivo se publica el reporte de caso clínico y se revisa la bibliografía. CASO CLÍNICO: Paciente de 32 años, en curso de las 23 semanas de embarazo. Debido a síntomas de COVID-19, con prueba PCR positiva, se hospitalizó para inicio de ventilación mecánica invasiva. Al noveno día de internamiento tuvo elevación de transaminasas y reporte de TAC de colecistitis aguda alitiásica. Se le indicó la colecistostomía percutánea, con la que se alivió el cuadro hepatobiliar. En el segundo tiempo quirúrgico se procedió a la cesárea. Tres días después experimentó mejoría ventilatoria y bioquímica gradual. A los 32 días de hospitalización se logró la intubación y, después de 54 días, se dio de alta del hospital, sin requerimiento de oxígeno suplementario. CONCLUSIONES: Encontrar, en conjunto con el síndrome de insuficiencia respiratoria aguda por COVID-19 grave que requiere ventilación mecánica invasiva, embarazo previable y colecistitis alitiásica pone en grave peligro a la embarazada y al equipo médico en múltiples dilemas médicos, quirúrgicos y bioéticos. La colecistostomía percutánea en pacientes con inestabilidad hemodinámica y la finalización del embarazo en caso de deterioro ventilatorio ante síndrome de insuficiencia respiratoria aguda es una opción controvertida. Lo conducente, sin duda, son los procedimientos basados en evidencia y las sesiones multidisciplinarias, incluyendo a la familia.
Abstract BACKGROUND: Pregnant women infected with SARS-CoV-2 were 2.9 times more likely to require invasive ventilation. Acute cholecystitis is the second most common surgical indication in pregnancy. In the literature search, no reports of concomitance of both diseases during pregnancy were found, for this reason the clinical case report is published and the literature is reviewed. CASE REPORT: 32-year-old female patient, in the course of 23 weeks of pregnancy. Due to symptoms of COVID-19, with positive PCR test, she was hospitalized for initiation of invasive mechanical ventilation. On the ninth day of hospitalization, she had elevated transaminases and CT report of acute cholecystitis alliasis. Percutaneous cholecystostomy was indicated, which relieved the hepatobiliary symptoms. In the second surgical stage, a cesarean section was performed. Three days later she experienced gradual ventilatory and biochemical improvement. After 32 days of hospitalization, intubation was achieved and, after 54 days, she was discharged from the hospital, without requiring supplemental oxygen. CONCLUSIONS: Finding, in conjunction with severe COVID-19 acute respiratory failure syndrome requiring invasive mechanical ventilation, pre-viable pregnancy, alliasic cholecystitis, places the pregnant woman and the medical team in serious medical, surgical, and bioethical dilemmas. Percutaneous cholecystostomy in patients with hemodynamic instability and termination of pregnancy in case of ventilatory deterioration in the face of acute respiratory failure syndrome is a controversial option. Evidence-based procedures and multidisciplinary sessions, including the family, are undoubtedly conducive.
ABSTRACT
@#BACKGROUND: It is controversial whether prophylactic endotracheal intubation (PEI) protects the airway before endoscopy in critically ill patients with upper gastrointestinal bleeding (UGIB). The study aimed to explore the predictive value of PEI for cardiopulmonary outcomes and identify high-risk patients with UGIB undergoing endoscopy. METHODS: Patients undergoing endoscopy for UGIB were retrospectively enrolled in the eICU Collaborative Research Database (eICU-CRD). The composite cardiopulmonary outcomes included aspiration, pneumonia, pulmonary edema, shock or hypotension, cardiac arrest, myocardial infarction, and arrhythmia. The incidence of cardiopulmonary outcomes within 48 h after endoscopy was compared between the PEI and non-PEI groups. Logistic regression analyses and propensity score matching analyses were performed to estimate effects of PEI on cardiopulmonary outcomes. Moreover, restricted cubic spline plots were used to assess for any threshold effects in the association between baseline variables and risk of cardiopulmonary outcomes (yes/no) in the PEI group. RESULTS: A total of 946 patients were divided into the PEI group (108/946, 11.4%) and the non-PEI group (838/946, 88.6%). After propensity score matching, the PEI group (n=50) had a higher incidence of cardiopulmonary outcomes (58.0% vs. 30.3%, P=0.001). PEI was a risk factor for cardiopulmonary outcomes after adjusting for confounders (odds ratio [OR] 3.176, 95% confidence interval [95% CI] 1.567-6.438, P=0.001). The subgroup analysis indicated the similar results. A shock index >0.77 was a predictor for cardiopulmonary outcomes in patients undergoing PEI (P=0.015). The probability of cardiopulmonary outcomes in the PEI group depended on the Charlson Comorbidity Index (OR 1.465, 95% CI 1.079-1.989, P=0.014) and shock index >0.77 (compared with shock index ≤0.77 [OR 2.981, 95% CI 1.186-7.492, P=0.020, AUC=0.764]). CONCLUSION: PEI may be associated with cardiopulmonary outcomes in elderly and critically ill patients with UGIB undergoing endoscopy. Furthermore, a shock index greater than 0.77 could be used as a predictor of a worse prognosis in patients undergoing PEI.
ABSTRACT
Objective:To explore the comparative study of video laryngoscopy combined with bronchial blocker and video laryngoscopy combined with double-lumen tube in the teaching of endotracheal intubation in thoracic surgery in the standardized residency training of anesthesia.Methods:The trainees of the standardized residency training were randomly divided into control group and experimental group for clinical teaching, with 25 ones in each group. The experimental group was treated with visual laryngoscopy combined with bronchial blocker, while the control group was treated with visual laryngoscopy combined with double-lumen tube group. The intubation time, intubation success rate, positioning time, hemodynamic changes, and complication incidence during intubation, as well as student assessment results were recorded. GraphPad Prism 6.0 was used for t test and Chi-square test. Results:The time of endotracheal intubation [(95.3±10.1) vs. (137.5±13.5)] and positioning time [(100.8±11.7) vs. (155.4±15.3)] in the experimental group were both shorter than those of the control group ( P< 0.001), the hemodynamic changes in patients with immediate intubation were smaller ( P<0.001), the success rate of intubation was higher (92% vs. 68%) ( P<0.001), the complication incidence was lower ( P<0.001) and the students' performance was higher ( P<0.001). Conclusion:In the anesthesia teaching of thoracic surgery, bronchial blocker can reduce the time of endotracheal intubation, lower the hemodynamic changes during intubation, cut down the incidence of complications, improve the success rate of endotracheal intubation and enhance the confidence of students.
ABSTRACT
Resumen: Reportamos el manejo exitoso de la vía aérea con intubación orotraqueal a través de una máscara laríngea AuraOnceTM en un paciente con lesión de la médula espinal cervical. Su uso fue como dispositivo de rescate de la vía aérea tras intubación orotraqueal fallida con laringoscopía directa y dificultad para la ventilación con mascarilla en una paciente traumatizada de 46 años. Se tomó la decisión de utilizar la mascarilla laríngea sin intubación como conducto para la colocación de un tubo orotraqueal, lo cual se realizó con éxito. Este uso alternativo de la mascarilla laríngea Ambu AuraOnce podría ser de gran valor para los trabajadores de la salud en países de escasos recursos donde los dispositivos avanzados para las vías respiratorias no están fácilmente disponibles.
Abstract: We reported a successful airway management in a patient with a diagnosed cervical spinal injury with a non-intubating laryngeal mask AuraOnceTM. Its use was as a rescue airway device after failed orotracheal intubation with direct laryngoscopy and difficulty with facemask ventilation in a 46-year-old trauma patient. The decision was made to use the non-intubating laryngeal mask as a conduit for the placement of an orotracheal tube, which was done successfully. This alternative use of the Ambu AuraOnce laryngeal mask could be of great value to healthcare workers in resource-poor countries where advanced airway devices are not readily available.
ABSTRACT
Introducción: Muchos enfermos de COVID-19 requieren ser ventilados. La laringoscopia directa (LD) es el método tradicional empleado en el manejo de la vía aérea; sin embargo, la videolaringoscopia (VL) es una alternativa en estos pacientes. Objetivo: Comparar la laringoscopia directa y la videolaringoscopia en el manejo de la vía aérea en pacientes con COVID-19. Métodos: Se realizó un estudio observacional retrospectivo. El universo y la muestra estuvieron conformado por los pacientes intubados por médicos de la brigada Henry Reeve en hospitales de Cancún y Ciudad de México. Se conformaron dos grupos; el Grupo laringoscopia directa con 91 pacientes y el Grupo videolaringoscopia con 103. Las variables estudiadas fueron: edad, sexo, número de predictores de una vía respiratoria anatómicamente difícil (VRAD), visualización de la apertura glótica, intentos de intubación y las complicaciones de la intubación. El análisis estadístico de los datos se realizó con el paquete estadístico SPSS 23.0. Resultados: Los grupos fueron comparables en cuanto a edad, sexo y predictores de vía respiratoria anatómicamente difícil. La visualización glótica completa o parcial en el grupo videolaringoscopia fue de 97 por ciento, mientras que en el grupo laringoscopia directa fue de 86 por ciento. La intubación endotraqueal al primer intento superó el 70 por ciento en el grupo VL y el 50 por ciento en el grupo LD. Las principales complicaciones encontradas fueron la desaturación y la hipotensión arterial con una mayor frecuencia en el grupo LD (40,7 por ciento y 49,5 por ciento). Conclusiones: La videolaringoscopia mejoró la visualización glótica y la intubación endotraqueal al primer intento, con menos complicaciones en los pacientes estudiados(AU)
Introduction: Many COVID-19 patients require ventilation. Direct laryngoscopy is the traditional method used for airway management; however, videolaryngoscopy is an alternative in these patients. Objective: To compare direct laryngoscopy and videolaryngoscopy for airway management in COVID-19 patients. Methods: A retrospective observational study was carried out. The universe and the sample consisted of patients intubated by physicians from Henry Reeve brigade at hospitals in Cancun and Mexico City. Two groups were formed: the direct laryngoscopy group, with 91 patients, and the videolaryngoscopy group, with 103 patients. The variables studied were age, sex, number of predictors of an anatomically difficult airway, visualization of the glottic opening, intubation attempts, and intubation complications. Statistical analysis of the data was performed using the SPSS 23.0 statistical package. Results: The groups were comparable in terms of age, sex and predictors of an anatomically difficult airway. Complete or partial glottic visualization in the videolaryngoscopy group was 97 percent , while in the direct laryngoscopy group it was 86 percent . Endotracheal intubation at the first attempt exceeded 70 percent in the videolaryngoscopy group and 50 percent in the direct laryngoscopy group. The main complications observed were desaturation and arterial hypotension with a higher frequency in the direct laryngoscopy group (40.7 percent and 49.5 percent , respectively). Conclusions: Video laryngoscopy improved glottic visualization and endotracheal intubation at the first attempt, with fewer complications in the patients studied(AU)

Resumen: Introducción: La utilización de dispositivos de barrera adicional para la intubación endotraqueal constituye un reto para la práctica médica durante la actual pandemia. Se pueden utilizar múltiples herramientas para intubación del paciente minimizando la exposición del operador sin afectar la seguridad del procedimiento. El médico debe evaluar y comprender adecuadamente cualquier estrategia adicional, ya que podría interferir con la intubación, aumentando el tiempo de manipulación. Objetivo: Comparar preferencia de los anestesiólogos entre dos dispositivos de barrera, uno diseñado con base en una lámina plástica versus caja de acrílico. Material y métodos: Incluimos 102 pacientes intervenidos de cirugías electivas y de urgencias que aceptaron participar en este estudio prospectivo, transversal y comparativo de manera voluntaria con previo consentimiento informado. Resultados: La lámina de plástico permite un menor tiempo de intubación, menos intentos de laringoscopía y disminuye dificultades de abordaje, además genera un grado de satisfacción mayor en el personal en comparación con dispositivos rígidos como la caja de acrílico. Conclusiones: Es posible obtener buenos resultados para instrumentar la vía aérea cuando se utilizan dispositivos de barrera adicional en personal entrenado. No obstante, teniendo en cuenta los hallazgos de este trabajo existen ventajas con el uso de lámina de plástico.
Abstract: Introduction: The use of additional barrier devices for endotracheal intubation constitutes a challenge for medical practice during the current pandemic. Multiple tools can be used for patient intubation minimizing operator exposure without compromising procedural safety. Any additional strategy must be properly evaluated and understood by the physician as it could interfere with intubation, increasing handling time. Objective: To compare anesthesiologists' preference between two barrier devices, one designed based on a plastic sheet vs an acrylic box. Material and methods: We included 102 patients who underwent elective and emergency surgeries who voluntarily agreed to participate in this prospective, cross-sectional and comparative study with prior informed consent. Results: The plastic sheet allows a shorter intubation time, fewer laryngoscopy attempts and reduces approach difficulties, in addition it generates a higher degree of satisfaction in the personnel compared to rigid devices such as the acrylic box. Conclusions: It is possible to obtain good results to instrument the airway when additional barrier devices are used in trained personnel. However, taking into account the findings of this work, there are advantages with the use of plastic sheeting.
ABSTRACT
El manejo especializado de la vía aérea (VA) es fundamental en las unidades de urgencia donde la intubación orotraqueal ha sido la técnica de elección para lograrlo. Una VA difícil se define como una situación clínica en la cual un equipo médico entrenado experimenta dificultades en la ventilación y/o en intubación. La obstrucción aguda de la VA constituye una de las emergencias médicas más extremas, requiriendo intervención inmediata. Se presenta el caso de un paciente con estridor inspiratorio con criterios inmediatos de intubación donde se evidencia un tumor en cuerdas vocales con obstrucción de la vía aérea.
Specialized airway management is essential in emergency units where endotracheal intubation has been the technique of choice. The difficult airway is defined as a clinical situation in which a trained medical team experiences difficulties in ventilation and, or intubation. Acute airway obstruction is one of the most extreme medical emergencies, requiring immediate intervention. We present the case of a patient with inspiratory stridor with quick criteria for intubation where a tumour in the vocal cords with airway obstruction is found.
ABSTRACT
El enfisema subcutáneo se produce como complicación frecuente en intervenciones quirúrgicas, técnicas invasivas, ventilación mecánica, lesiones traqueales y neumotórax. La progresión fuera del tórax con afectación facial, abdominal e incluso inguinal puede producir un síndrome compartimental con compresión de estructuras aledañas como la tráquea y vasos del cuello, tal situación se ha denominado enfisema subcutáneo masivo. En este documento se reporta el caso de un paciente que desarrolló un enfisema subcutáneo masivo como signo precoz de lesión traqueal asociada a la intubación y ventilación a presión positiva.
Subcutaneous emphysema occurs as a frequent complication in surgical interventions, invasive techniques, mechanical ventilation, tracheal injuries and pneumothorax. Progression outside the thorax with facial, abdominal, and even inguinal involvement can produce compartment syndrome with compression of surrounding structures such as the trachea and neck vessels. This situation has been called massive subcutaneous emphysema.This document reports the case of a patient who developed massive subcutaneous emphysema as an early sign of tracheal injury associated with intubation and positive pressure ventilation.
ABSTRACT
INTRODUCTION: Laryngoscopy and endotracheal intubation has been the mainstay in providing adequate airway management, delivering general anaesthesia but are associated with hypertension, tachycardia and arrhythmias. These haemodynamic responses may be more hazardous in hypertensive patients. OBJECTIVE: In this study, we aimed to compare the haemodynamic response elicited by laryngoscopic endotracheal intubation with laryngeal mask airway insertion, in ASA II of adult hypertensive patients. METHODS: The study conducted on 100 hypertensive patients of either sex aged between 20 and 60 years belonging to ASA II grade and scheduled for elective surgery. The patients were randomly divided into two groups of 50 patients each. In one group (Group I) laryngoscopic endotracheal intubation was done and in another group (Group II) laryngeal mask airway was inserted. Baseline vitals of the patients (SBP, DBP, MAP, HR, SpO2) were documented. Patients were given inj. Midazolam 2mg IM and Phenargan 25 mg IM as premedication before the elective surgery. General anaesthesia was administered. Haemodynamics including heart rate, blood pressure and SpO2 were recorded every minute till intubation or insertion and at 1,3,5 minutes after intubation or insertion and then every 5 minutes till 20 minutes. RESULTS: All the haemodynamic responses (SBP,DBP,MAP,HR) in Laryngoscopy + Endotracheal Intubation Group compared to the Laryngeal Mask Airway Insertion Group was statistically signi?cant as the p value is <0.05. CONCLUSION: The laryngeal mask airway may be used for airway management during anaesthesia in hypertensive patients on treatment in whom the pressor response would be deleterious.
ABSTRACT
RESUMEN Introducción: La fístula traqueoesofágica consecutiva a intubación endotraqueal prolongada es una lesión grave con elevada morbimortalidad. El alto índice de sospecha, diagnóstico precoz, resolución de las complicaciones y un tratamiento quirúrgico definitivo son los pilares fundamentales en los cuales descansa su manejo correcto. Objetivo: Describir el comportamiento y manejo de la fístula traqueoesofágica en pacientes con intubación endotraqueal prolongada. Presentación del caso: Paciente de 34 años de edad que sufrió trauma craneoencefálico grave con necesidad de intubación endotraqueal prolongada. Su evolución fue favorable, con recuperación neurológica, pero presentaba tos incontrolable después de la deglución, aumento de las secreciones respiratorias y pérdida de 30 Kg de peso no resuelta, lo que motivó se le realizara tomografía computarizada multicorte dual sincronizada con el electrocardiograma, la que permitió de forma rápida y no invasiva, llegar al diagnóstico de la fístula traqueoesofágica. Conclusiones: La intubación endotraqueal prolongada constituye la causa principal de la aparición de la fístula traqueoesofágica. El mecanismo de producción fundamental fue la isquemia provocada por la compresión de las paredes posterior de la tráquea y anterior del esófago entre el manguito insuflado del tubo endotraqueal y la sonda nasogástrica. La tomografía computarizada multicorte dual sincronizada con el electrocardiograma permite realizar el diagnóstico de esta complicación.
ABSTRACT Introduction: Tracheoesophageal fistula following prolonged endotracheal intubation is a serious lesion with high morbidity and mortality. The high index of suspicion, early diagnosis, resolution of complications and definitive surgical treatment are the fundamental pillars on which its correct management rests. Objective: Describe the behavior and management of tracheoesophageal fistula in patients with prolonged endotracheal intubation. Case Presentation: A 34-year-old patient who suffered severe head trauma with the need of prolonged endotracheal intubation. His evolution was favorable, with neurological recovery, but he presented uncontrollable cough after swallowing, increased respiratory secretions and unsolved loss of 30 Kg of weight, which motivated to perform to him a dual multi-cut computed tomography synchronized with the electrocardiogram, which allowed quickly and non-invasively, to reach the diagnosis of tracheoesophageal fistula. Conclusions: Prolonged endotracheal intubation is the main cause of the appearance of tracheoesophageal fistula. The fundamental production mechanism was ischemia caused by compression of the posterior walls of the trachea and anterior walls of the esophagus between the inflated cuff of the endotracheal tube and the nasogastric tube. The dual multi-cut computed tomography synchronized with the electrocardiogram allows the diagnosis of this complication.

Background: Succinylcholine has been the main neuromuscular blocking agent for the endotracheal intubation in rapid sequence induction with some adverse effects. This study was conducted to find a better alternate drug with minimal adverse effects and easy for intubations. Thus, our study aimed to compare the onset time, duration of action, intubating condition and hemodynamic effect of rocuronium bromide at the dose of 0.8 mg/kg and Succinylcholine at the dose of 1.5 mg/kg. Materials and methods: A double blinded randomized control study was conducted among 60 patients undergoing surgery each groups having 30 patients, Duration of action, Hemodynamic parameters, and intubating conditions were assessed after administering drugs in each group. Appropriate statistical tests were applied P value < 0.05 was considered to be significant Results: The mean of onset of action of succinylcholine is significantly shorter than that of rocuronium (48.07 ± 4.04 Vs 74.4 ± 9.1); and duration of action succinylcholine is significantly shorter than that of the rocuronium (3.85 ± 0.33 Vs 44.4 ± 4.7). Both the drugs significantly elevated mean Heart rate, Systolic Blood Pressure, Diastolic Blood pressure, MAP from intubation to subsequent intervals. Conclusion: The rocuronium bromide (0.8 mg/kg) has longer duration of action and slower onset of action than succinylcholine (1.5 mg/kg) with excellent intubating condition and minimal alteration in hemodynamic profile. Hence rocuronium bromide (0.8 mg/kg) can be used as an alternative to Succinylcholine (1.5 mg/kg) in selected situations.
ABSTRACT
Background:Cisatracurium is the stereoisomer of atracurium but has considerably higher neuromuscular blocking potency, better hemodynamic profile and no association with dose-dependent histamine release, as compared with the parent compound(1)(2,3). On the other hand, 2 ED95dose s of cis-atracurium (100? g/kg) do not create satisfactory intubating conditions such as those seen with equipotent doses of atracurium.There are limited studies which provide us the clarity of a better neuromuscular blocker in terms of intubation and maintainence amongst the two with the most optimum dose. Material And Methods:The study designed as randomised controlled trial, recruited 150 patients into three groups: Group A-atracurium 0.5 mg/kg(2×ED95), Group B and C-cis-atracurium 0.2 mg/kg (4×ED95) and 0.4 mg/kg (8×ED95)respectively and compared them on the basis of onset, duration of action, recovery time, haemodynamic effect and signs of histamine release clinically. Result:Patients in Group C had significantly shorter onset time of block when c ompared with group A & B. Mean duration of block after loading dose was significantly shorter in Group A than group B & C. Group B had a shorter duration of block than C. Recovery time of block in group A was significantly shorter than group B & C. Conclusion:Cis-atracurium in dose of 0.2 mg/kg seems to be better alternative to atracurium 0.5 mg/kg and cis-atracurium 0.4 mg/kg in providing faster onset, intermediate duration of action with fast recovery and it can be used for intubation as well as maintenance.
ABSTRACT
Objective:To investigate the influencing factors of endotracheal intubation and mechanical ventilation (ETI-MV) in patients with acute respiratory distress syndrome (ARDS) caused by viral pneumonia, and to provide evidence for individualized use of ETI-MV.Methods:Patients with ARDS due to viral pneumonia admitted to the respiratory intensive care unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed from November 2017 to March 2022. The gender, age, concomitant diseases, clinical symptoms and signs, complications, lab results, ARDS severity, infectious virus type, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), respiratory support methods and prognosis-related variables were collected. Univariate analysis was performed on each factor, and the variables with statistical significance in the univariate analysis were subjected multivariate logistic regression analysis. The receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive value of each index for the implementation of ETI-MV.Results:A total of 117 patients were enrolled in the study, including 61 patients in the ETI-MV group, and 3 patients (4.9%), 39 patients (63.9%) and 19 patients (31.1%) with mild, moderate and severe ARDS, respectively. There were 56 patients in non-ETI-MV group, and the mild, moderate and severe ARDS cases were 16 cases (28.6%), 38 cases (67.8%) and 2 cases (3.6%), respectively. There was significant difference between the two groups ( P < 0.05). Univariate analysis showed that during 24 hours admitted to RICU, the levels of interleukin-6 [IL-6 (ng/L): 104.0±90.0 vs. 62.4±76.0], oxygenation index [PaO 2/FiO 2 (mmHg, 1 mmHg≈0.133 kPa): 123.9±30.9 vs. 173.6±28.5], the proportion of cases with pulmonary infiltrating opacity distribution range ≥ 3/4 lung fields [85.3% (52/61) vs. 21.5% (12/56)], APACHE Ⅱ score ≥ 16.5 [67.2% (41/61) vs. 42.9% (24/56)], the rate of nosocomial invasive aspergillus infection [14.8% (9/61) vs. 3.6% (2/56)], the percentage of nosocomial bacterial infection [16.4% (10/61) vs. 3.6% (2/56)], and the lowest CD4 + T lymphocyte count in the course of the disease [cells/mm 3: 192.2±35.8 vs. 215.0±58.3] had significant differences between ETI-MV and non-ETI-MV group (all P < 0.05). Multivariate Logistic regression analysis showed that during 24 hours admitted to RICU the distribution range of pulmonary infiltrating opacity ≥ 3/4 the lung fields [odds ratio ( OR) = 12.527, 95% confidence interval (95% CI) = 3.279-47.859, P < 0.001], APACHE Ⅱ score ≥ 16.5 ( OR = 30.604, 95% CI = 4.318-216.932, P = 0.001), PaO 2/FiO 2 ( OR = 0.948, 95% CI = 0.925-0.972, P < 0.001), CD4 + T lymphocytes cell count ( OR = 0.975, 95% CI = 0.955-0.995, P = 0.015), and nosocomial bacterial infection ( OR = 38.338, 95% CI = 1.638-897.158, P = 0.023) were independent risk factors for ETI-MV. The area under the ROC curve (AUC) of ROC showed that PaO 2/FiO 2 had the greatest predictive value for ETI-MV, with AUC of 0.903, sensitivity of 91.1% and specificity of 95.1% in case of cutoff value of 151 mmHg. The AUC of pulmonary infiltrating opacity distribution range was 0.809, the sensitivity of 85.2%, specificity of 78.6% when the cutoff value was ≥ 3/4 lung field. APACHE Ⅱ scores had the lowest predictive value for selecting ETI-MV, with AUC of 0.704, sensitivity of 83.6% and specificity of 57.1% under the cutoff value was 16.5. Conclusions:For patients with ARDS caused by viral pneumonia, PaO 2/FiO 2 is still the classic reference for selecting ETI-MV, however, the distribution range of pulmonary infiltrating opacity and the systemic severity of the disease during 24 hours admitted to the RICU may provide supplemental helpful information to determine whether the patients choose ETI-MV, especially for moderate ARDS.
ABSTRACT
Objective:To combine micro-course and flipped classroom, integrate the application of online WeChat group and teaching video, build a new teaching framework, and seek the application of flipped classroom based on "micro-course" in clinical skills training of general anesthesia and tracheal intubation for medical students.Methods:A total of 82 clinical medicine intern students of Batch 2015 and 2016 from Nnajing Drum Tower Hospital were selected as the research subjects to complete the internship (for two weeks). The teaching reform group (44 people) adopted the flipped classroom based on "micro-course"; the traditional group (38 people) adopted traditional teaching. Organized by the undergraduate teaching and research department, the number of tracheal intubation cases and the number of excellent scores were recorded during the two-week internship in anesthesia. After the rotation, a questionnaire survey was conducted to evaluate the mastery of endotracheal intubation operation and satisfaction with the teaching and training arranged by the department. SPSS 23.0 was used to conduct t test and non-parametric test. Results:The number of outstanding cases of tracheal intubation in the teaching reform group was higher than that in the traditional group, and the number of outstanding cases of tracheal intubation in girls was higher than that in boys, and the difference was statistically significant ( P<0.05). The self-assessed scores of the students' mastery of tracheal intubation and the satisfaction with clinical practice training in the teaching reform group were higher than those in the traditional group, and the difference was statistically significant ( P<0.05). Conclusion:Compared with traditional teaching, the flipped classroom based on "micro-course" has more advantages in the clinical skills training of medical tracheal intubation.
ABSTRACT
In the emergency department, open endotracheal suctioning for mechanically ventilated patients with endotracheal intubation will lead to the spread of respiratory droplets and aerosols, polluting the surrounding environment and medical staff. The traditional heat-and-moisture exchanger has the effect of warming and humidifying, and can block pathogenic microorganisms, but it does not have the function of inserting a sputum suction tube. When the heat-and-moisture exchanger is pulled out for sputum suction, it is easy to cause sputum splash, which pollutes the surrounding environment and medical personnel. The addition of closed sputum suction devices will increase the economic burden on patients. Thus, the medical staff of emergency department of the First People's Hospital of Tongxiang City of Zhejiang Province designed a new type of heat-and-moisture exchanger with anti-splash sputum suctioning function and obtained the National Utility Model Patent of China (ZL 2021 2 0017615.0). The new heat-and-moisture exchanger is mainly composed of a receiving cavity, a connecting tube, a sputum suction tube intubation tube, a sealing valve, etc. The disposable sputum suction tube can be used to insert sputum suction, and at the same time, it can prevent the secretion from splashing to ensure sealing. The patent combines the humidification and pathogen blocking functions of the heat-and-moisture exchanger with the anti-splash sputum suctioning function, which is suitable for use in the emergency and critical care medicine departments and has clinically practical value.
ABSTRACT
Introducción: A finales del año 2019 se reportaron casos de neumonía atípica en Wuhan provocados por un nuevo coronavirus. La intubación endotraqueal puede causar contaminación del personal de salud. Las pautas recientes prefieren la videolaringoscopia porque aumenta las posibilidades de intubación y evita del contacto cercano con el paciente. Objetivos: Describir el abordaje de la vía aérea con videolaringoscopia en pacientes con COVID-19 e identificar las principales complicaciones aparecidas durante la intubación endotraqueal. Métodos: Se realizó un estudio descriptivo, transversal, en el periodo de diciembre de 2020 a febrero de 2021, en el Centro Médico Naval de la Ciudad de México. El universo estuvo conformado por 178 pacientes con COVID-19 que requirieron intubación endotraqueal. Se tomó una muestra de 103 pacientes los cuales fueron atendidos por los médicos cubanos. Resultados: Los pacientes mayores de 60 años representaron el 63,1 por ciento de los casos y el sexo masculino el 65 por ciento El 42,1 por ciento tuvieron un predictor de vía aérea difícil y el 30,1 por ciento, dos o más predictores. Se visualizó completamente la glotis en el 39,8 por ciento de los casos y, parcialmente, en un 57,3 por ciento. La intubación al primer intento se logró en el 73,8 por ciento. Las principales complicaciones encontradas fueron la desaturación (33 por ciento) y la hipotensión arterial (37,9 por ciento). Conclusiones: La videolaringoscopia podría mejorar la visualización de la apertura glótica y la intubación endotraqueal al primer intento. La desaturación y la hipotensión arterial fueron complicaciones que podrían esperarse en los pacientes con la COVID-19 durante este procedimiento(AU)
Introduction: At the end of 2019, cases of atypical pneumonia were reported in Wuhan caused by a new coronavirus. Endotracheal intubation may cause contamination of healthcare personnel. According to recent guidelines, videolaryngoscopy is preferred, because it increases the chances of intubation and avoids close contact with the patient. Objectives: To describe airway management with videolaryngoscopy in patients with COVID-19 and to identify the main complications that appeared during endotracheal intubation. Methods: A descriptive and cross-sectional study was carried out, in the period from December 2020 to February 2021, at the Naval Medical Center in Mexico City. The universe consisted of 178 patients with COVID-19 who required endotracheal intubation. A sample of 103 patients was taken, who were cared for by Cuban doctors. Results: Patients older than 60 years represented 63.1 percent of the cases, while the male sex represented 65 percent. 42.1 percent had one predictor of difficult airway and 30.1 percent had two or more predictors. The glottis was visualized fully in 39.8 percent of cases and partially in 57.3 percent. Intubation on the first attempt was achieved in 73.8 percent. The main complications found were desaturation (33 percent) and arterial hypotension (37.9 percent). Conclusions: Videolaryngoscopy could improve visualization of the glottic opening and endotracheal intubation on the first attempt. Desaturation and hypotension were complications that could be expected in COVID-19 patients during this procedure(AU)

En pacientes con infección por SARS-CoV-2 la intubación endotraqueal es un procedimiento con riesgo elevado de contagio. La videolaringoscopia complementa la protección del profesional, pero los videolaringoscopios comerciales son caros y no siempre están disponibles en las terapias intensivas pediátricas argentinas. El objetivo fue describir la práctica de intubación en un modelo de cabeza de simulación de lactante con un videolaringoscopio artesanal de bajo costo.Quince pediatras sin experiencia previa con el dispositivo participaron de una práctica de intubación en una cabeza de simulación con un videolaringoscopio artesanal. El tiempo promedio del primer intento fue de 116,4 segundos (intervalo de confianza del 95 % [IC95 %]: 84,8-148,0) y, el del siguiente fue de 44,2 segundos (IC95 %: 27,760,6). El tiempo disminuyó de forma significativa en el segundo intento (p : 0,0001). El dispositivo permitió la intubación exitosa en todos los intentos acortando la duración del procedimiento en la segunda práctica
In patients with SARS-CoV-2 infection, endotracheal intubation is a procedure with a high risk for transmission. A videolaryngoscopy is a supplementary level of health care provider protection, but commercial videolaryngoscopes are expensive and not always available in pediatric intensive care units in Argentina. Our objective was to describe intubation practice using an infant head mannequin with a low-cost, handcrafted videolaryngoscope.Fifteen pediatricians with no prior experience using the device participated in an intubation practice in a head mannequin with a handcrafted videolaryngoscope. The average time for the first attempt was 116.4 seconds (95 % confidence interval [CI]: 84.8-148.0) and, for the second one, 44.2 seconds (95 % CI: 27.7-60.6). Time decreased significantly for the second attempt (p: 0.0001).A successful intubation was achieved with the device in all attempts, and the procedure duration decreased with the second practice
