Prolonged Invasive Ventilatory Support in ICU Patients: A Detailed Cohort Analysis

Objetivo

To identify patients requiring prolonged invasive ventilatory support (>7 days) and the factors associated with this extended duration.

Métodos

A cohort study involving patients under invasive ventilatory support admitted to a private ICU in João Pessoa, Brazil, in 2023.

Resultados

Among 140 patients, 45 (32.1%) required ventilatory support for more than 7 days. These patients had a median ventilation time of 15 (10.5-22) days versus 1 (1-3) days in others, p<0.001, with 8 (17.8%) requiring tracheostomy. Compared to others, these patients had lower PaO2/FiO2 ratios at admission (320 [242.85-523.8] vs. 409 [292.97-785.71], p=0.01), were more likely to be medical patients (77.8% vs. 56.9%, p=0.001), older (>65 years) (77.8% vs. 67.7%, p=0.004), and admitted for neurological reasons (11.1% vs. 9%, p<0.001). They were also more frequently postoperative neurosurgery patients (7.4% vs. 3.3%, p<0.001) and had a history of stroke (14.8% vs. 12.3%, p<0.001) or neoplasia (11.1% vs. 6.2%, p<0.001). There was no significant difference in SAPS3 (47 [38-51] vs. 47 [38-59.5]) or SOFA (8 [6-11] vs. 7 [3-9], p=0.03).

Conclusão

Patients requiring prolonged invasive ventilatory support did not differ significantly in frailty, comorbidity, or SAPS3 severity compared to those with shorter durations. However, they exhibited higher SOFA scores and were more likely to be older, admitted for medical or neurological reasons, and have a history of stroke or neoplasia.
