Abstract
Background: Mortality of newborns with Hypoplastic Left Heart Syndrome (HLHS) is mainly concentrated after Norwood procedure (NP) stage 1 palliation (S1P) and between S1P and stage 2 palliation (S2P). Standardized management of these patients may help to control hospital mortality. Aim of the study was to evaluate the impact on hospital mortality of a standardized perioperative management (SPM) for newborns requiring S1P in a low volume center for NP.
Methods: A consecutive series of patients undergoing S1P from January 1, 2002 to December 31, 2006 were retrospectively compared, by a "before and after" design, with those receiving a SPM (i.e. use of selective cerebral perfusion, near infrared spectroscopy, delayed sternal closure, modified ultrafiltration) from January 1st, 2007 to December 31st, 2018. Demographic, intraoperative and postoperative characteristics were collected. Univariate and multivariate analyses assessed differences before and after SPM.
Results: Ninety-one newborns underwent S1P in the considered period; of 74 eligible patients, 25 did not receive SPM, while 49 received SPM. Hospital mortality after S1P was 31% (CI 21-44%). The introduction of a SPM did not affect hospital mortality both at the univariate-(28% vs. 29%, P=0.959) and at the multivariate analysis (HR 1.85, P=0.62). Mortality was 12% (CI 6-25%) between hospital discharge after S1P and S2P and 8% (CI 3-22%) between S2P and S3P.
Conclusions: The use of a SPM for HLHS newborns requiring S1P was not effective in reducing hospital mortality in a low volume center. We suggest a collaboration between Italian Pediatric Cardiac Centers to manage HLHS patients.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
