Randomized Controlled Trial Comparative StudyA randomized, controlled trial on dexmedetomidine for providing adequate sedation and hemodynamic control for awake, diagnostic transesophageal echocardiography.
Transesophageal echocardiography (TEE) has become established as a sensitive and accurate diagnostic method for the rapid assessment of myocardial function. It was theorized that dexmedetomidine (Precedex; Hospira, Inc, Lake Forest, IL) might prove to be useful for sedating patients while undergoing TEE. ⋯ The authors concluded that dexmedetomidine appears equivalent in achieving adequate levels of sedation without increasing the rate of respiratory depression or decreasing oxygen saturation compared with standard therapy, and it may be better in achieving desired hemodynamic results.

Comparative StudyThe revised digital transcutaneous PCO2/SpO2 ear sensor is a reliable noninvasive monitoring tool in patients after cardiac surgery.
The aim of this study was to validate the revised SenTec V-Sign 2 sensor (SenTec AG, Therwil, Switzerland) for combined noninvasive continuous assessment of pulse rate, pulse oximetry (SpO(2)), and transcutaneous carbon dioxide tension (PtcCO(2)) in adults after cardiac surgery. ⋯ Transcutaneous capnometry using the revised V-Sign 2 sensor at the earlobe is a reliable monitoring tool during the recovery period of patients after cardiac surgery. This approach has the potential to reduce the number of arterial blood gas samples.

Comparative StudyIntraoperative assessment of mitral valve area after mitral valve repair: comparison of different methods.
In the present study, 3 different methods to measure the mitral valve area (MVA) after mitral valve repair (MVRep) were studied. Data obtained immediately after repair were compared with postoperative data. The objective was to determine the feasibility and correlation between intraoperative and postoperative MVA data. ⋯ The MVA recorded immediately after valve repair, using PHT, correlated and agreed with MVA data obtained in the postoperative period. These results contrast with previously published data and could highlight the impact of hemodynamic function during the assessment of MVA.
