CO and SV decreased significantly from supine to left-lateral position (CO supine: 193.4 (168.0 to 229.6) ml kgmin; CO left-lateral: 172.0 (154.9 to 201.6) ml kgmin, P&lt;0.0001; SV supine: 3.0 (2.7 to 4.0) ml; SV left-lateral: 2.7 (2.4 to 3.2) ml, P&lt;0.0004). Conversely, SVRI increased in left-lateral position: SVRI supine: 18865±9244 dyns cm m; SVRI left-lateral: 21203±10059 dyns cm m, P&lt;0.0001). All variables returned to the initial value when infants were back in the supine position. HR and blood pressure did not change.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSION: &lt;/b&gt;In stable infants, CO and SV decrease and SVRI increases, in left-lateral position.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/28079876?dopt=Abstract</style></custom1></record></records></xml>
