Abstract
Introduction
Recent studies show that mechanical ventilation (MV) is necessary in only 5-10% of cardiosurgical patients. Thus, this finding denies the theory arguing that a prolonged period of MV (24 hours to 7 days) reduces the risk of complications. Based on these considerations, strategies have developed, i.e. the Fast Track (FT), with the aim of encouraging early extubation (1 to 8 hours after surgery). The objectives of this review are: to verify the effectiveness of FT in terms of reducing post-operative complications, mortality and costs, to analyse the operating procedures and inclusion criteria of each protocol and to outline nursing care in the whole process.
Methods
Literature search was performed in Cochrane, PubMed, and CINAHL databases. No limits have been applied on study design and publication timespan. Population included adult patients who underwent cardiac surgery with admission to an intensive care unit and were mechanically ventilated.
Results
16 articles (including 8 RCT) have been selected. The protocols require that nurses, based on specific parameters, assess the possibility of weaning from sedation and early extubation according to standardised practices. Early extubation decreases the risk of MV-related complications by decreasing hospitalization lenght and thus total costs by at least 3%. No significant differences have been found between FT and standard of care regarding postoperative complications and mortality.
Conclusions
Taking into account both the proven applicability, safety and efficacy of FT protocols and their high heterogeneity in published studies, that prevent their comparison, further research is needed to identify a reliable algorithm for early extubation based on pre-operative, intraoperative and postoperative data.
Key messages
Early extubation decreases the risk of MV-related complications by decreasing hospitalization lenght and thus total costs by at least 3%. Recent studies show that mechanical ventilation (MV) is necessary in only 5-10% of cardiosurgical patients.
