Abstract
CARMODY, María Candela et al. Prolonged mechanical ventilation in postoperative cardiovascular subjects. A case series. Argentinian j. respiratory physical therapy [online]. 2022, vol.4, n.1, pp.33-39. Epub Feb 23, 2022. ISSN 2618-4095. http://dx.doi.org/10.58172/ajrpt.v4i1.194.
Objective:
To describe the demographic characteristics and proportion of postoperative cardiovascular subjects who require prolonged mechanical ventilation (PMV) and to analyze associated factors.
Materials and method:
A case series study was conducted on subjects over 18 years of age who required cardiac surgery via median sternotomy between July 2017 and November 2018. Subjects with missing data were excluded, and subjects who died during surgery were eliminated. A logistic regression analysis was performed to identify predicting factors associated with PMV.
Results:
Of the 70 subjects analyzed, 17.1% required PMV, with a mortality of 41.7%. In the univariate analysis, obesity, length of hospital stay, duration of surgery, need of extracorporeal circulation, postoperative complications, and sequential organ failure assessment (SOFA) scores in the immediate postoperative period were significantly associated with PMV.
Conclusion:
The proportion of subjects requiring PMV was higher than the reported in the literature. The duration of surgery, obesity, need of extracorporeal circulation, length of hospital stay, postoperative complications, and SOFA scores in the immediate postoperative period were associated with PMV.
