Meta Analysis Comparative StudyEsmolol reduces perioperative ischemia in noncardiac surgery: a meta-analysis of randomized controlled studies.
Literature increasingly has suggested how beta-blockers could be associated with reductions of mortality and morbidity in noncardiac surgery. Recently, the POISE trial showed that beta-blockers could be harmful in the perioperative period. The authors performed a meta-analysis to evaluate the clinical effects of esmolol in noncardiac surgery. ⋯ Esmolol seemed to reduce the incidence of myocardial ischemia in noncardiac surgery without increasing the episodes of hypotension and bradycardia. Large randomized trials are necessary to confirm these promising results.

Comparative StudyValidity of an arterial pressure waveform analysis device: does the puncture site play a role in the agreement with intermittent pulmonary artery catheter thermodilution measurements?
The measurement of cardiac output is a key element in the assessment of cardiac function. Recently, a pulse contour analysis-based device without need for calibration became available (FloTrac/Vigileo, Edwards Lifescience, Irvine, CA). This study was conducted to determine if there is an impact of the arterial catheter site and to investigate the accuracy of this system when compared with the pulmonary artery catheter using the bolus thermodilution technique (PAC). ⋯ The FloTrac/Vigileo system was shown to not produce exactly the same CO data when used in radial and femoral arteries, even though the percentage error was close to the clinically acceptable range. Thus, the impact of the introduction site of the arterial catheter is not negligible. The agreement with thermodilution was low.

Randomized Controlled Trial Comparative StudyProphylactic vasopressin in patients receiving the angiotensin-converting enzyme inhibitor ramipril undergoing coronary artery bypass graft surgery.
The purpose of this study was to compare the effects of continuation versus discontinuation of the angiotensin-converting enzyme (ACE) inhibitor ramipril and assess the efficacy of prophylactic vasopressin infusion on hemodynamic stability and vasoactive drug requirements in patients undergoing coronary artery bypass graft (CABG) surgery. ⋯ Preoperative ACE inhibitor continuation predisposed to hypotension upon the induction of anesthesia and in the post-CPB period. Prophylactic low-dose vasopressin infusion prevented post-CPB hypotension. Low-dose vasopressin can be considered as potential therapy in these patients.
