Analysis of related factors of mechanical ventilation in EICU patients with severe respiratory disease at different ages

ObjectiveTo analyze the related factors of mechanical ventilation in emergency intensive care unit (EICU) patients with severe respiratory disease at different age, and to provide basis for the formulation of mechanical ventilation treatment plan for EICU patients with severe respiratory disease at different ages.

MethodsA total of 148 EICU patients with severe respiratory disease were selected and divided into groups according to their age.The mechanical ventilation time, success rate of one-time weaning and mortality were compared among the groups.

ResultsThe intubation time decreased gradually with the increase of patients' age, and the intubation time in 50-59 year-old group and ≥ 90 year-old group was relatively short(P < 0.05).There was no significant difference in intubation time between different gender patients in the same group(P>0.05).The success rate of one-time weaning was the lowest(50.0%) and the mortality was the highest (35.7%) in the < 39 year-old group; the success rate of one-time weaning in 40-49 year-old group and 60-69 year-old group was higher, which was 83.3% and 83.9%, respectively; the mortality of weaning in 40-49 year-old group and 50-59 year-old group was lower, which was 8.3% and 9.5%, respectively; but there was no significant difference in the success rate and mortality of one-time weaning in each group(P>0.05).

ConclusionsThe age of 40-59 years old is the best age for the application of mechanical ventilation, and patients under 39 years old have a higher risk of mechanical ventilation weaning.This study provides a reference for the formulation of mechanical ventilation treatment plan and clinical nursing of EICU patients with severe respiratory diseases at different ages.
