ABSTRACT

INTRODUCTION:

COVID-19-associated mortality in patients who require mechanical ventilation is unknown in the Mexican population.

OBJECTIVE:

To describe the characteristics of Mexican patients with COVID-19 who required mechanical ventilation.

METHODS:

Observational cohort study carried out in an intensive care unit from March 25 to July 17, 2020. Data were obtained from a prospective database and electronic medical records, and were analyzed with the chi-square test, Fisher's exact test or Mann-Whitney's U-test.

RESULTS:

One hundred patients required mechanical ventilation; median age was 56 years, 31 % were females and 97 % were Latin American. Most common comorbidities were obesity (36 %), diabetes (26 %), hypertension (20 %), and chronic or end-stage kidney disease (10 %). At the end of the analysis, 11 patients remained in the ICU, 31 had been discharged alive and 58 (65.2 %) died; survivors were younger, had lower scores on severity and organ dysfunction scales, lower levels of C-reactive protein at ICU admission, were less likely to receive hemodialysis and vasopressors, and had longer hospital and ICU stays.

CONCLUSIONS:

This study adds information on the presentation and results of SARS-CoV-2-infected patients who require mechanical ventilation.
RESUMEN

INTRODUCCIÓN:

La mortalidad por COVID-19 en quienes requieren ventilación mecánica se desconoce en la población mexicana.

OBJETIVO:

Describir las características de pacientes mexicanos con COVID-19 que requirieron ventilación mecánica.

MÉTODOS:

Estudio de cohorte observacional en una unidad de terapia intensiva, del 25 de marzo al 17 de julio de 2020. Los datos se obtuvieron de una base de datos prospectiva y de registros clínicos electrónicos; fueron analizados con c2, prueba exacta de Fisher o prueba U de Mann-Whitney.

RESULTADOS:

Cien pacientes recibieron ventilación mecánica, la edad media fue de 56 años, 31 % era del sexo femenino y 97 %, latinoamericano. Las comorbilidades más comunes fueron obesidad (36 %), diabetes (26 %), hipertensión (20 %) y enfermedad renal crónica o renal terminal (10 %). Al término del análisis, 11 pacientes permanecían en la UCI, 31 egresaron vivos y 58 (65.2 %) fallecieron; los sobrevivientes fueron más jóvenes, con menores puntuación en las escalas de gravedad y disfunción orgánica, menores niveles de proteína C reactiva al ingreso a la UCI, menor propensión a hemodiálisis, necesidad de, necesidad de vasopresores y con mayor estancia hospitalaria y en la UCI.

CONCLUSIONES:

Este estudio agrega información sobre la presentación y resultados de pacientes con ventilación mecánica infectados con SARS-CoV-2.
