Considering comparative data, there was no significant difference in the prevalence of tracheal stenosis or major bleeding between percutaneous and surgical tracheostomy. In relation to wound infection, we have found a reduction associated with the original Ciaglia technique when compared with that with the surgical tracheostomy. Considering all published data reporting long-term outcomes pooled proportion meta-analysis indicates a trend toward a higher rate of tracheal stenosis and an increased risk of major bleeding and wound infection for surgical tracheostomies. This finding may be biased as a result of targeted patient selection, and further, high-quality long-term comparative data are needed to confirm these findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
