Sedation during mechanical ventilation: a systematic review.
OBJECTIVE
A systematic review was performed to determine the most effective agent with which to sedate adult patients who have respiratory failure that requires mechanical ventilation in the medical intensive care unit.


METHODS
A computerized literature search of MEDLINE, a U.S. National Library of Medicine online database, from 1966 to August 1998 was conducted. All selected articles were reviewed to identify other relevant articles.


METHODS
Inclusion criteria were as follows: a) population-adults with respiratory failure who received mechanical ventilation in a medical intensive care unit; b) design-prospective, randomized controlled trial; c) intervention-sedation; and d) primary outcome-successful sedation.


METHODS
Of 71 potentially relevant articles, only 15 randomized trials fulfilled all four selection criteria.


RESULTS
Clinical heterogeneity among studies precluded statistical pooling of results.


CONCLUSIONS
More research is needed to determine the most effective agent with which to sedate adult patients who have respiratory failure that requires mechanical ventilation in the medical intensive care unit.
