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.

An 11-year, single-institution analysis of intra-aortic balloon pump use in cardiac surgery.
The primary objective of this study was to analyze perioperative intra-aortic balloon pump (IABP) insertion in patients undergoing cardiac surgery in the authors' institution from 1995 to 2005 and to propose an explanation for changes in use over this period. A secondary objective was to assess patient variables associated with IABP use. ⋯ From 1995 to 2005, preoperative, intraoperative, and postoperative IABP use decreased by approximately 60% in cardiac surgery patients. Simultaneously, the use of TEE and milrinone each doubled. Although a cause-effect relationship cannot be established from the present study's observational data, the trends coincide and may be related.

Increased preoperative white blood cell count predicts postoperative atrial fibrillation after coronary artery bypass surgery.
To better understand the relationship between humoral and cellular markers of inflammation and postoperative atrial fibrillation (AF). ⋯ In this cohort of patients undergoing CABG surgery, preoperative leukocytosis was a significant predictor of AF independent of CRP.
