Black Box Warning: Is Ketorolac Safe for Use After Cardiac Surgery?
Objective: In 2005, after the identification of cardiovascular safety concerns with the use of nonsteroidal anti-inflammatory drugs (NSAIDs), the FDA issued a black box warning recommending against the use of NSAIDs following cardiac surgery. The goal of this study was to assess the postoperative safety of ketorolac, an intravenously administered NSAID, after cardiac surgery.Design: Retrospective observational study.Setting: Single center, regional hospital.Participants: A total of 1,309 cardiac surgical patients (78.1% coronary bypass, 28.0% valve) treated between 2006 and 2012.Interventions: A total of 488 of these patie...

Remote Ischemic Preconditioning Reduces Cardiac Troponin I Release in Cardiac Surgery: A Meta-Analysis
Conclusions: Current evidence suggests that RIPC reduces cardiac troponin I release in patients undergoing cardiac surgery. The clinical significance of these observations merits further investigation.

Effects of Body Surface Area-Indexed Calculations in the Morbidly Obese: A Mathematical Analysis
Conclusion: In morbidly obese patients, cardiac and stroke indices can be misleading relative to the underlying raw values (CO and SV) as a result of distortion by widely used BSA formulae. The authors caution against relying on threshold cardiac and stroke indices as triggers for the initiation of hemodynamic therapies in the morbidly obese. Further research on what BSA formula should be used on patients with very extreme body types is warranted.

Predicting Fluid Responsiveness During Infrarenal Aortic Cross-Clamping in Pigs
Objective: Infrarenal aortic cross-clamping (ACC) induces hemodynamic disturbances that may affect respiratory-induced variations in stroke volume and, therefore, affect the ability of dynamic parameters such as pulse-pressure variation (PPV) to predict fluid responsiveness. Since this issue has not been investigated yet to authors’ knowledge, the hypothesis was tested that ACC may change PPV and impair its ability to predict fluid responsiveness.Design: Prospective laboratory experiment.Setting: A university research laboratory.Participants: Nineteen anesthetized and mechanically ventilated pigs.Interventions: Two cours...

Arterial Closure Devices for Treatment of Inadvertent Large-Caliber Catheter Insertion Into the Subclavian or Carotid Artery: A Case Series of Five Patients
CENTRAL VENOUS CATHETERIZATION is a common procedure in today`s medicine. Iatrogenic complications occur in up to 34% of catheter placements including 5% of arterial puncture. A variety of complications by arterial puncture have recently been described, including airway obstruction, pseudoaneurysms, arteriovenous fistulas, and even stroke caused by arterial thrombosis or embolization. Although 2-D ultrasound assisted insertion of large central venous catheters may reduce adverse events, it might not be available in an emergency setting, and the use of ultrasound guidance requires training. Depending on anatomic localizatio...

Prediction of Volume-Responsiveness During One-Lung Ventilation: A Comparison of Static, Volumetric, and Dynamic Parameters of Cardiac Preload
Conclusions: Under these OLV experimental conditions, the volumetric and dynamic parameters of preload, as well as CVP, seemed to be of similar value in predicting volume responsiveness.

Effects of Catecholamines on Microcirculation During General Inhalation Anesthesia
Conclusions: During general anesthesia with sevoflurane, the infusion of clinical dosages of norepinephrine and dobutamine did not alter sublingual perfusion, although the expected systemic hemodynamic alterations were induced.

Hemodynamic Pressure Waveform Analysis in Predicting Fluid Responsiveness
Objective: To assess the usefulness of central venous pressure (CVP), diastolic right ventricular pressure, and pulmonary capillary wedge pressure (PCWP) waveform analysis in predicting fluid responsiveness.Design: A prospective observational study.Setting: Tertiary care university hospital.Patients: Forty-four patients undergoing coronary artery bypass grafting.Interventions: Analysis of the a/v wave ratio of the PCWP, CVP, and right ventricular dP/dt to predict an increase in stroke volume>15% after the administration of 500mL of colloid.Measurements and Main Results: Forty-four patients were enrolled in this study and 7...

High Thoracic Epidural Analgesia as an Adjunct to General Anesthesia is Associated With Better Outcome in Low-to-Moderate Risk Cardiac Surgery Patients
Conclusion: This large, uniquely matched single-center cohort was generated, and, subject to the listed limitations the authors concluded that supplemental HTEA to general anesthesia had a better outcome in low-risk cardiac surgery patients, with a significantly lower 6-month mortality rate compared with the control group. However, regression analysis revealed that HTEA only had an independently positive effect on the frequency of postoperative dialysis.

Chronic Pressure-Overload Hypertrophy Attenuates Vortex Formation Time in Patients With Severe Aortic Stenosis and Preserved Left Ventricular Systolic Function Undergoing Aortic Valve Replacement
Objective: Transmitral blood flow produces a vortex ring that enhances the hydraulic efficiency of early left ventricular (LV) filling. The effect of pressure-overload hypertrophy on the duration of LV vortex ring formation (vortex formation time [VFT]) is unknown. The current investigation tested the hypothesis that chronic LV pressure-overload hypertrophy produced by severe aortic stenosis (AS) reduces VFT in patients with preserved LV systolic function undergoing aortic valve replacement.Design: Observational study.Setting: Veterans Affairs Medical Center.Participants: After the Institutional Review Board's approval, 8 ...
