[Effects of mechanical ventilation on vascular endothelial function in patients with systemic inflammatory response syndrome].

Abstract

OBJECTIVE:

To study the effect of mechanical ventilation on vascular endothelial function in patients with systemic inflammatory response syndrome (SIRS).

METHODS:

All patients showing SIRS were divided into two groups: mechanical ventilation (MV) group (n=35) and non-MV group (n=43). Nitric oxide (NO), angiotensin-conversion enzyme (ACE), endothelin-1 (ET-1), and circulating endothelial cells (CEC) of each patient were measured on the 1 st and 7 th day after admission.

RESULTS:

Acute physiology and chronic health evaluation II (APACHE II) scores of MV group were significantly higher than those of non-MV group at different time points after admission (all P<0.01). There was significant correlation of APACHE II with each inflammatory mediator at each time point and the coefficients were similar. By analysis of covariance, NO and APACHE II score were negatively correlated, other indexes were positively correlated with APACHE II score. There were not significant variances in two groups on the 1 st hospital day (all P>0.05); but on the 7 th hospital day, the levels of ET-1, ACE and CEC were all increased, but NO decreased (all P<0.05). NO content and APACHE II score could forecast the prognosis with the conclusion of Logistic analysis.

CONCLUSION:

There are very high correlations between the degree of vascular endothelial dysfunction and the seriousness of diseases in patients with SIRS. MV exerts significant damage to the vascular endothelial function in patients.
