RESUMO
Background: More than 600 people die each year in developed countries from complications at the time of orotracheal intubation. Studies have shown that all predictors used so far have low ability to predict difficult airway. When analyzing this ability, both clinical suspicion, indirect laryngoscopy and even the different individual examinations showed predictive values higher than 80%. Objective: To evaluate the concordance between the Predictive Index of Difficult Intubation (PIDI) and the Cormack regarding the diagnosis of difficult intubation in patients undergoing open and laparoscopic cholecystectomy under balanced general anesthesia. Material and methods: Observational, prospective, cross-sectional, analytical concordance study, carried out in patients aged 18 to 60 who underwent open and laparoscopic cholecystectomy. The sample was probabilistic, the statistical analysis applied univariate and bivariate, specifically the Kappa index. Results: A total of 96 patients were analyzed; 77 were female with a mean age of 40.4 years. Said sample presented a PIDI of easy intubation in 75%, discreet difficulty in 21.9% and frank difficulty in 3.1%. After conventional direct laryngoscopy, 75% presented Cormack I, 16.7% presented Cormack II, 8.3% presented Cormack III. The bivariate analysis with the Kappa index statistic showed a value of 0.242. Conclusions: It is accepted the alternative hypothesis demonstrating that there is a correlation between the PIDI and the Cormack concerning the diagnosis of difficult intubation in patients undergoing open and laparoscopic cholecystectomy under balanced general anesthesia.
Introducción: más de 600 personas mueren al año en los países desarrollados por complicaciones con la intubación orotraqueal. Estudios han demostrado que todos los predictores utilizados hasta el momento tienen baja capacidad para predecir la vía aérea difícil. Al analizar esta capacidad, tanto la sospecha clínica como la laringoscopía indirecta y los diferentes exámenes individuales mostraron valores predictivos superiores al 80%. Objetivo: evaluar la concordancia entre el Índice predictivo de intubación difícil (IPID) y el Cormack respecto al diagnóstico de intubación difícil en pacientes intervenidos de colecistectomía abierta y laparoscópica bajo anestesia general balanceada. Material y métodos: estudio observacional, prospectivo, transversal, analítico de concordancia, realizado en pacientes de 18 a 60 años intervenidos de colecistectomía abierta y laparoscópica. La muestra fue de tipo probabilístico, el análisis estadístico aplicado univariado y bivariado, específicamente el Índice de Kappa. Resultados: se analizaron 96 pacientes; 77 fueron del sexo femenino, con una media de 40.4 años de edad. Se presentó un IPID de intubación fácil en 75%, dificultad discreta en 21.9% y dificultad franca en 3.1%. Posterior a la laringoscopía directa convencional, 75% presentó Cormack I, 16.7% Cormack II y 8.3% Cormack III. El análisis bivariado con el Índice de Kappa evidenció un valor de 0.242. Conclusiones: se acepta la hipótesis alterna que demuestra que sí hay correlación entre el IPID y el Cormack respecto al diagnóstico de intubación difícil en pacientes intervenidos de colecistectomía abierta y laparoscópica bajo anestesia general balanceada.

BACKGROUND AND OBJECTIVES: In this study, we aimed to determine the risk of obstructive sleep apnea (OSA) in patients undergoing elective surgery and its relationship with difficult intubation (DI). METHODS: This prospective, descriptive, cross-sectional study was conducted between December 2018 and February 2020 in the anesthesiology and reanimation service of a training and research hospital. The study included patients who were ASA I...II, 18 years of age, and older who underwent elective surgery under general anesthesia. A form regarding the baseline characteristics of the participants as well as STOP-Bang score, Mallampati, and Cormack-Lehane classification was used to collect the data. RESULTS: The study included 307 patients. It was determined that 64.2% of patients had a high risk of OSA. The presence of DI (determined by repeated attempts at intubation) was 28.6% in the high-risk OSA group, while there was no DI in the low-risk OSA group. A statistically significant difference was found between the groups in terms of OSA risk according to the presence of DI according to repeated attempts, Cormack-Lehane classification, and Mallampati classification (p...<...0.001). CONCLUSION: Due to the high rate of DI in patients with a high risk of OSA, the security of the airway in these patients is endangered. Early clinical recognition of OSA can help in designing a safer care plan.

Resumen: Introducción: El manejo correcto de la vía aérea en los pacientes politraumatizados es crucial, ya que es necesario tener una vía aérea segura y proveer adecuada ventilación sin emperorar una probable lesión medular. Objetivo: Determinar el efecto de la maniobra de fijación en línea (MILS del inglés Manual In-Line Stabilisation) en la clasificación de Cormack-Lehane (CL), así como la correlación con el índice de masa corporal (IMC). Material y métodos: En un estudio descriptivo en el Centro Hospitalario del Estado Mayor Presidencial en la Ciudad de México se incluyeron 56 pacientes con estado físico ASA I a IV. El anestesiólogo realizó la laringoscopía directa bajo MILS y valoró el grado de CL. Inmediatamente después se reposicionó al paciente en posición de olfateo, se efectuó nueva laringoscopía directa y se revaloró de nuevo el grado de CL. Resultados: Los grados del CL fueron significativamente diferentes entre la posición MILS versus olfateo. Los grados de CL fueron en su mayoría altos cuando se posicionó al paciente en MILS (75% de los pacientes clasificados entre III y IV) y disminuyeron significativamente al ser cambiados a posición de olfateo. Conclusión: Se observa mejoría del CL cuando se cambia de posición MILS a olfateo.
Abstract: Introduction: Correct airway management of polytraumatized patients is crucial because of the necessity of securing the airway and providing adequate ventilation without worsening a probable spinal cord injury. Objective: Determine the effect of manual inline stabilization (MILS) on Cormack-Lehane classification and if there is any correlation with body mass index (BMI). Material and methods: In a descriptive study at the Centro Hospitalario del Estado Mayor Presidencial in Mexico City, we included 56 patients with ASA physical status I to IV. The anesthesiologist performed direct laryngoscopy while MILS was performed and observed the CL grade. Immediately after, the patient was repositioned into the sniffing position, direct laryngoscopy was performed, and the CL grade was observed again. Results: The CL grades observed were significantly different between MILS vs. Sniffing position. CL grades were mainly high when positioned in MILS (75% classified as grades III and IV) and diminished significantly when changed to the sniffing position. Conclusion: Improvement of CL grade was observed when changing from MILS to sniffing position.
RESUMO
Resumen: Se realizó un ensayo clínico controlado, prospectivo, comparativo, aleatorizado, ciego simple. Objetivo: Determinar la correlación y valor predictivo de las escalas de evaluación de vía aérea e intubación difícil, obesidad, hoja McCoy y videolaringoscopio tipo Airtraq®. Material y métodos: 152 pacientes programados para cirugía, con antecedentes de obesidad y factores de riesgo de ventilación e intubación difícil sometidos a anestesia general. Se formaron dos grupos: grupo 1 intubación con hoja McCoy y grupo 2 videolaringoscopio Airtraq®. Resultados: En la estadística de contraste de ventilación difícil se obtuvo significancia estadística con p < de 0.05 para todos los factores, excepto el ronquido. En predictores de intubación difícil, la clasificación de Mallampati y Cormack-Lehane obtuvo p < 0.05, con sensibilidad de 63 y 68% respectivamente, con valor predictivo negativo alto para todos los factores. El promedio de intentos fue uno y duración de 55-59 segundos en ambos grupos. No hubo diferencias con el uso de hoja McCoy y Airtraq®. Conclusiones: La intubación orotraqueal fue exitosa en 97% de los casos gracias al uso de predictores de intubación difícil y de dispositivos para manejo de la misma.
Abstract: A controlled, prospective, comparative, randomized, simple blind clinical trial was conducted. Objective: Determine the correlation and predictive value of the airway assessment and difficult intubation scales, obesity, McCoy sheet and Airtraq® type videolaryngoscope. Material and methods: 152 patients scheduled for surgery, with a history of obesity and risk factors for difficult ventilation and intubation under general anesthesia. Two groups were formed: group, intubation with McCoy sheet and group 2, Airtraq® videolaryngoscope. Results: In the contrast statistics of difficult ventilation, statistical significance was obtained with p < 0.05 for all factors except snoring. In predictors of difficult intubation, the Mallampati and Cormack-Lehane classification obtained p < 0.05, with sensitivity of 63 and 68% respectively, with a high negative predictive value for all factors. The average of attempts was 1 and duration 55-59 seconds, in both groups. There were not differences with the use of McCoy sheet and Airtraq®. Conclusions: Orotracheal intubation was successful in 97% of cases, thanks to the use of difficult intubation predictors and devices for managing it.
RESUMO
Abstract Background and objectives: In this study, we aimed to investigate the predictive value of different airway assessment tools, including parts of the Simplified Predictive Intubation Difficulty Score (SPIDS), the SPIDS itself and the Thyromental Height Test (TMHT), in intubations defined as difficult by the Intubation Difficulty Score (IDS) in a group of patients who have head and neck pathologies. Methods: One hundred fifty-three patients who underwent head and neck surgeries were included in the study. The Modified Mallampati Test (MMT) result, Thyromental Distance (TMD), Ratio of the Height/Thyromental Distance (RHTMD), TMHT, maximum range of head and neck motion and mouth opening were measured. The SPIDSs were calculated, and the IDSs were determined. Results: A total of 25.4% of the patients had difficult intubations. SPIDS scores >10 had 86.27% sensitivity, 71.57% specificity and 91.2% Negative Predictive Value (NPV). The results of the Receiver Operating Curve (ROC) analysis for the airway screening tests and SPIDS revealed that the SPIDS had the highest area under the curve; however, it was statistically similar to other tests, except for the MMT. Conclusions: The current study demonstrates the practical use of the SPIDS in predicting intubation difficulty in patients with head and neck pathologies. The performance of the SPIDS in predicting airway difficulty was found to be as efficient as those of the other tests evaluated in this study. The SPIDS may be considered a comprehensive, detailed tool for predicting airway difficulty.
Resumo Justificativa e objetivos: Neste estudo, avaliamos o valor preditivo de diferentes ferramentas de avaliação das vias aéreas, incluindo componentes do Escore Simplificado Preditivo de Intubação Difícil (ESPID), o próprio ESPID e a Medida da Altura Tireomentoniana (MATM), em intubações definidas como difícies pelo Escore de Dificuldade de Intubação (EDI) em um grupo de pacientes com patologia de cabeça e pescoço. Método: Incluímos no estudo 153 pacientes submetidos a cirurgia de cabeça e pescoço. Coletamos os resultados do Teste de Mallampati Modificado (TMM), Distância Tireomentoniana (DTM), Razão Altura/Distância Tireomentoniana (RADTM), MATM, amplitude máxima de movimentação da cabeça e pescoço e da abertura da boca. Os ESPIDs foram calculados e os EDIs, determinados. Resultados: Observamos intubação difícil em 25,4% dos pacientes. Os escores de ESPID > 10 tiveram sensibilidade de 86,27%, especificidade de 71,57% e valor preditivo negativo de 91,2% (VPN). O resultado da análise da curva de operação do receptor (curva ROC) para os testes de avaliação das vias aéreas e ESPID mostrou que o ESPID tinha a maior área sob a curva; no entanto, foi estatisticamente semelhante a outros testes, exceto para o TMM. Conclusões: O presente estudo demonstra o uso prático do ESPID na previsão da dificuldade de intubação em pacientes com patologia de cabeça e pescoço. O desempenho do ESPID na predição de via aérea difícil mostrou-se tão eficiente quanto os demais testes avaliados neste estudo. O ESPID pode ser considerado ferramenta abrangente e detalhada para prever via aérea difícil.

BACKGROUND: The difficulties with airway management is the main reason for pediatric anesthesia-related morbidity and mortality. OBJECTIVE: To assess the value of modified Mallampati test, Upper-Lip-Bite test, thyromental distance and the ratio of height to thyromental distance to predict difficult intubation in pediatric patients. DESIGN: Prospective analysis. MEASUREMENTS AND RESULTS: Data were collected from 5 to 11 years old 250 pediatric patients requiring tracheal intubation. The Cormack and Lehane classification was used to evaluate difficult laryngoscopy. Sensitivity, specificity, positive predictive value and AUC values for each test were measured. RESULTS: The sensitivity and specificity of modified Mallampati test were 76.92% and 95.54%, while those for ULBT were 69.23% and 97.32%. The optimal cutoff point for the ratio of height to thyromental distance and thyromental distance for predicting difficult laryngoscopy was 23.5 (sensitivity, 57.69%; specificity, 86.61%) and 5.5cm (sensitivity, 61.54%; specificity, 99.11%). The modified Mallampati was the most sensitive of the tests. The ratio of height to thyromental distance was the least sensitive test. CONCLUSION: These results suggested that the modified Mallampati and Upper-Lip-Bite tests may be useful in pediatric patients for predicting difficult intubation.

BACKGROUND AND OBJECTIVES: The purpose of this study was to review the experiences of an anesthesiology department regarding the use of a C-MAC videolaryngoscope in unexpected failed intubation attempts. METHODS: Data were analyzed from 42 patients whose intubation attempts using Macintosh direct laryngoscopes had failed, and on whom a C-MAC videolaryngoscope was utilized as the primary rescue device. The success rate of C-MAC in intubation was assessed, and laryngeal views from both devices were compared. RESULTS: The Cormack and Lehane score was III in 41 patients, and IV in one patient, with the Macintosh laryngoscope, while Cormack and Lehane score was I in 27 patients, II in 14 and III in one with CMAC. Tracheal intubation with CMAC was successful on the first attempt in 36 patients (86%), and on the second attempt in 6 patients (14%). No complications were observed other than minor damage (blood on blade) in 8 patients (19%). CONCLUSION: These data provide evidence for the clinical effectiveness of C-MAC videolaryngoscope in managing the unexpected failed intubations in routine anesthesia care. The C-MAC videolaryngoscope is efficient and safe as a primary rescue device in unexpected failed intubations.

Justificativa e objetivos: O objetivo deste estudo foi fazer uma revisão das experiências de um departamento de anestesiologia em relação ao uso do videolaringoscópio C-MAC em tentativas malsucedidas de intubação. Métodos: Analisamos os dados de 42 pacientes, cujas tentativas de intubação com o uso delaringoscopia direta (Macintosh) tinham falhado e nos quais o videolaringoscópio C-MAC foi usado como o dispositivo de resgate primário. A taxa de sucesso do C-MAC em intubação foi avaliada e a visão da laringe em ambos os dispositivos foi comparada. Resultados: Com o laringoscópio Macintosh, o escore de Cormack e Lehane foi 3 em 41 pacientes e 4 em um paciente e com o CMAC, foi 1 em 27 pacientes, 2 em 14 pacientes e 3 em um paciente. Intubação traqueal com CMAC foi bem-sucedida em 36 pacientes (86%) na primeira tentativa e em seis pacientes (14%) na segunda tentativa. Nenhuma complicação foi observada, além de pequena lesão (sangue na lâmina) em oito pacientes (19%). Conclusão: Esses dados fornecem evidência para a eficácia clínica do videolaringoscópio C-MAC no manejo de intubações malsucedidas inesperadas em assistência rotineira de anestesia. O videolaringoscópio C-MAC é eficiente e seguro como dispositivo de resgate primário em intubações malsucedidas inesperadas. .

Justificación y objetivos: El objetivo de este estudio fue hacer una revisión de las experiencias de un departamento de anestesiologia con relación al uso del videolaringoscopio C-MAC® en intentos de intubación que fracasaron. Métodos: Analizamos los datos de 42 pacientes, cuyos intentos de intubación con el uso de laringoscopia directa (Macintosh) habían fallado y en los cuales el videolaringoscopio C-MAC® fue usado como el dispositivo de rescate primario. Se calculó la tasa de éxito del C-MAC® en la intubación y se comprobó la visión de la laringe en los 2 dispositivos. Resultados: Con el laringoscopio Macintosh, la puntuación de Cormack y Lehane fue 3 en 41 pacientes y 4 en un paciente; y con el C-MAC®, fue 1 en 27 pacientes, 2 en 14 pacientes y 3 en un paciente. La intubación traqueal con C-MAC® fue exitosa en 36 pacientes (86%) en el primer intento y en 6 pacientes (14%) en el segundo intento. No se observaron complicaciones, a no ser una pequena lesión (sangre en la lámina) en 8 pacientes (19%). Conclusiones: Esos datos suministran evidencias para la eficacia clínica del videolaringoscopio C-MAC® en el manejo de intubaciones no exitosas inesperadas en asistencia de rutina en anestesia. El videolaringoscopio C-MAC® es eficiente y seguro como dispositivo de rescate primario en intubaciones no exitosas inesperadas. .
