Randomized Controlled TrialEffect of Continuous Paravertebral Dexmedetomidine Administration on Intraoperative Anesthetic Drug Requirement and Post-Thoracotomy Pain Syndrome After Thoracotomy: A Randomized Controlled Trial.
To assess the effect of paravertebral administration of dexmedetomidine as an adjuvant to local anesthetic on the intraoperative anesthetic drug requirement and incidence of post-thoracotomy pain syndrome. ⋯ Paravertebral dexmedetomidine administration resulted in decreased intraoperative anesthetic drug requirement, less pain, and lower requirements of supplemental opioid in the postoperative period. However, it had no effect on the incidence of post-thoracotomy pain syndrome.

Observational StudyContinuous Monitoring of Lactate Using Intravascular Microdialysis in High-Risk Cardiac Surgery: a Prospective Observational Study.
To assess the accuracy and applicability of a novel system, not requiring calibration, for continuous lactate monitoring with intravascular microdialysis in high-risk cardiac surgery. ⋯ Lactate concentration increased significantly after high-risk cardiac surgery. The intravascular microdialysis technique for lactate measurement provided acceptable accuracy and can be used for continuous blood lactate monitoring in cardiac surgery.

Accuracy and Trending Ability of the Fourth-Generation FloTrac/Vigileo System in Patients With Low Cardiac Index.
To determine the accuracy and trending ability of the fourth-generation FloTrac/Vigileo in patients with low cardiac index by comparing FloTrac/Vigileo-derived cardiac index with that measured by 3-dimensional echocardiography. ⋯ The degree of accuracy of the fourth-generation FloTrac/Vigileo in patients with low cardiac index was not acceptable, and high systemic vascular resistance in patients with low cardiac index may have contributed to this inaccuracy. The tracking ability of the fourth-generation FloTrac/Vigileo after phenylephrine administration or cardiac resynchronization therapy was below acceptable limits.

Randomized Controlled TrialUse of McGrath MAC Videolaryngoscope to Assist Transesophageal Echocardiography Probe Insertion in Intubated Patients.
Transesophageal echocardiography (TEE) probe insertion with the conventional blind insertion technique may be difficult in anesthetized and intubated patients. The use of a videolaryngoscope may facilitate the insertion of the TEE probe. The aim of this study was to compare the conventional technique with the use of the McGrath MAC videolaryngoscope for TEE probe insertion in terms of success rate, duration of insertion, and complications in patients undergoing cardiovascular surgery. ⋯ The use of the McGrath MAC videolaryngoscope for TEE insertion in cardiovascular surgery patients increases the success rate and reduces pharyngeal injuries compared to the conventional technique. The use of the McGrath MAC videolaryngoscope for TEE insertion causes similar hemodynamic changes as in the conventional blind insertion technique.
