Randomized Controlled Trial Observational StudyThe Precision of Pulmonary Artery Catheter Bolus Thermodilution Cardiac Output Measurements Varies With the Clinical Situation.
To investigate the effects of ventilatory mode, injectate temperature, and clinical situation on the precision of cardiac output measurements. ⋯ Clinical precision of cardiac output measurements is reduced significantly during spontaneous relative to controlled ventilation. The differences in precision between repeated measurement series within the temperature/ventilation combinations indicate influence of other situation-specific factors not related to ventilatory mode. Compared with tepid injectate in patients breathing spontaneously, the precision is 3-fold better with cold injectate and controlled ventilation.

Review Meta Analysis Comparative StudyA Comparison of the Efficacy and Adverse Effects of Double-Lumen Endobronchial Tubes and Bronchial Blockers in Thoracic Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials.
To compare the efficacy and adverse effects of using bronchial blockers (BBs) and double-lumen endobronchial tubes (DLTs). ⋯ While BBs are associated with a lower incidence of airway injury and a lower severity of injury, DLTs can be placed quicker and more reliably.

Multicenter StudyFollow-Up After Cardiac Surgery Should be Extended to at Least 120 Days When Benchmarking Cardiac Surgery Centers.
Short-term (30 days) mortality frequently is used as an outcome measure after cardiac surgery, although it has been proposed that the follow-up period should be extended to 120 days to allow for more accurate benchmarking. The authors aimed to evaluate whether mortality rates 120 days after surgery were comparable to general mortality and to compare causes of death between the cohort and the general population. ⋯ This study supported an extended follow-up period after cardiac surgery when benchmarking cardiac surgery centers. Regardless of preoperative heart function, heart failure was the consistent leading cause of death.
