Review Meta AnalysisLevosimendan reduces cardiac troponin release after cardiac surgery: a meta-analysis of randomized controlled studies.
The authors performed a meta-analysis to investigate the effects of levosimendan in cardiac surgery. Inotropic drugs have never shown beneficial effects on outcome in randomized controlled studies, with the possible exception of levosimendan. ⋯ Levosimendan has cardioprotective effects, resulting in reduced postoperative cardiac troponin release.

Transesophageal echocardiography for verification of the position of the electrocardiographically-placed central venous catheter.
Compare changes in P-wave amplitude of the intra-atrial electrocardiogram (ECG) and its corresponding transesophageal echocardiography (TEE)-controlled position to verify the exact localization of a central venous catheter (CVC) tip. ⋯ The study suggests that the position of the CVC tip is located parallel to the SVC and 1.5 cm above the crista terminalis if the P wave starts to decrease during withdrawal of the catheter. The authors recommend that ECG control as per their study should be routinely used for placement of central venous catheters via the right internal jugular vein.
