Signaling molecules for early detection of adverse interactions during mechanical ventilation in animal models

The early identification of adverse interactions during mechanical ventilation, investigated by multiplexed immunoanalysis. Twenty piglets (average age 7 weeks, weight 23 kg) were intubated and divided into groups: A, spontaneously breathing; B, protectively ventilated; C, ventilated with injurious strategy; D, ventilated with lung disability. At the 1st hour (time-1) and 12th hour (time-2) of the study, brain natriuretic peptide (BNP), intercellular cell adhesion molecules (ICAM-1), vascular cell adhesion molecules (VCAM-1), tumor necrosis factor-alpha (TNF-alpha), and interleukin-6 (Il-6) were analyzed in the blood. The injurious ventilated group C exhibited an increase in both cell adhesion molecules (p
