Comparative StudyAssessment of trending ability of cardiac output monitors by polar plot methodology.
To develop a valid statistical method of showing acceptable cardiac output (CO) trending ability when new CO monitors are compared to a reference standard, such as thermodilution, using polar coordinates. ⋯ Polar plots can be used to show the trending ability of CO monitors in comparative validation studies. They overcome the deficiencies of concordance analysis, which uses the direction of change as a statistic and ignores the magnitude of change in CO.

Comparative StudyInteraction between spinal opioid and adenosine receptors in remote cardiac preconditioning: effect of intrathecal morphine.
Intrathecal morphine is cardioprotective and also triggers spinal adenosine release. This study investigated the role of spinal and peripheral adenosine receptors in intrathecal morphine cardioprotection. ⋯ Both central and peripheral adenosine receptors are involved in the signaling of intrathecal morphine preconditioning. Central receptors are important in the initiation of the process, whereas peripheral receptors have a role in ongoing mediation of the protective effect.
