ABSTRACT

Introduction. VAP is the most frequent HAIs infection in our country, which generates more costs and hospital stay, as well as an increase in morbidity and mortality of patients admitted to public and private hospital units. It is undoubtedly the number one enemy to combat for health professionals and a goal to consider in the MUEC (Single Quality Assessment Model).
Objective. To evaluate the differences in incidence of VAP, days of stay and days of MV, in critically ill patients treated in the ICU (Intensive Care Unit) with active and passive humidification. Analysis period November 2021 to August 2024.
Material and methods. Intervention: all mechanically ventilated patients were fitted with a continuous active humidification circuit and a manometer for continuous COT pressure measurement, expectoration cultures were taken upon admission, 72 hours after and during MV during their stay in the ICU, with monthly registration from March 2023 to August 2024.
Results. A decrease in days of stay in the ICU, duration of MV and decrease in incidence of VAP was observed in the group with active humidification and continuous manometry versus the group with passive humidification without continuous manometry: Stay: 2.5 to 10, versus 4.5-17.5 with a p value 0.009. Duration of MV: 4-14 with average 7 days versus 5-17.5 average 10.0, p 0.024. VAP occurred in 5 patients (5.6%) and 84 (94.4%) did not present it in the active humidification group, versus 16 patients (19.8%) who presented it in the passive humidification group, with a HR (CI95 %) of 3.51 (1.35-9-17) with a value of p0.005.
Discussion and conclusion. In our study, a decrease in days of stay, days of MV and incidence of VAP was observed in the ICU when using active humidification and continuous manometry.
