Resumen
Introducción: se han encontrado tasas de intubación de hasta 33% en pacientes con diagnóstico de COVID-19. Algunas cohortes han informado la presencia de disnea en el 84.1% de los pacientes intubados y este ha sido el único síntoma asociado con la intubación. La saturación de oxígeno < 90% y el aumento de la frecuencia respiratoria también han sido descritos como predictores de intubación.
Objetivo: analizar los factores de riesgo asociados a intubación en pacientes con COVID-19 al momento de su admisión hospitalaria.
Material y métodos: se realizó un estudio observacional, transversal, analítico y retrospectivo. El universo de estudio consistió en pacientes mayores de 18 años, hospitalizados por diagnóstico de infección por virus SARS-CoV-2 del 1 abril de 2020 al 31 abril de 2021 en el Hospital de Especialidades “Dr. Bernardo Sepúlveda Gutiérrez” del Centro Médico Nacional.
Resultados: se analizaron un total de 300 pacientes. La media de edad de los pacientes intubados fue de 59.17 años (p < 0.001, intervalo de confianza del 95% [IC 95%] −9.994 a −3.299). En general, el 76.7% (230) de los pacientes tenía antecedentes de una o más comorbilidades preexistentes, incluida la hipertensión en 42.3% (127), la obesidad en 36.7% (110) y la diabetes mellitus en 34.3% (103).
Conclusiones: las principales características clínicas de los pacientes hospitalizados por COVID-19 en nuestro centro que requirieron de intubación son muy similares a las observadas en distintos centros, entre ellas el sexo masculino, la edad mayor de 50 años y la obesidad, que fueron las más prevalentes.
Abstract
Background: Intubation rates up to 33% have been found in patients diagnosed with COVID-19. Some cohorts have reported the presence of dyspnea in 84.1% of intubated patients, being this the only symptom associated with intubation. Oxygen saturation < 90% and increased respiratory rate have also been described as predictors of intubation.
Objective: To analyze the risk factors associated with intubation in patients hospitalized for COVID-19 at their admission.
Material and methods: An observational, retrospective, analytical, cross-sectional study was carried out. The universe of study consisted of patients over 18 years of age hospitalized due to a diagnosis of SARS-CoV-2 virus infection from April 1, 2020 to April 31, 2021 in the Hospital de Especialidades (Specialties Hospital) “Dr. Bernardo Sepúlveda Gutiérrez” at the National Medical Center.
Results: The mean age of intubated patients was 59.17 years (95% confidence interval [95% CI] −9.994 to −3.299, p < 0.001). Overall, 76.7% (230) of patients had a history of one or more preexisting comorbidities, including hypertension in 42.3% (127), obesity in 36.7% (110), and diabetes mellitus in 34.3% (103).
Conclusions: The main clinical characteristics of patients hospitalized for COVID-19 in our center who required intubation are very similar to those observed in different centers, including male sex, age over 50 years and obesity, which were the most common.
