Comparative StudyThe agreement between ventricular volumes and ejection fraction by transesophageal echocardiography or a combined radionuclear and thermodilution technique in patients after coronary artery surgery.
To study the reproducibility of and agreement between perioperative transesophageal echocardiographic (TEE) and radionuclide (RN) assessment of ventricular volumes and ejection fraction (EF). ⋯ EF measured by TEE area length and Simpson's rule method are as reproducible as TEE FAC and are more accurate estimates of RN EF. Poor agreement between methods of measuring end-diastolic volume was observed.

The association among gastric mucosal pH, endotoxemia, and low systemic vascular resistance after cardiopulmonary bypass.
Previously, it was found that a number of patients suffer a "low systemic vascular resistance syndrome" after cardiopulmonary bypass, and this was hypothesized to be secondary to endotoxemia, resulting from intestinal ischemia during bypass. ⋯ The investigators therefore could not find any evidence that intestinal ischemia during bypass, as measured by gastric mucosal pH, predisposes to endotoxemia, or low systemic vascular resistance after cardiac surgery.

Randomized Controlled Trial Clinical TrialActive compression-decompression cardiopulmonary resuscitation does not improve survival in patients with prehospital cardiac arrest in a physician-manned emergency medical system.
To examine the efficacy of a new method of cardiac resuscitation, active compression-decompression cardiopulmonary resuscitation (ACD CPR), in prehospital cardiac arrest. ⋯ ACD CPR did not improve, outcome and practical performance was complicated. Therefore, this technique should not be performed routinely, or without strict supervision in prehospital cardiac arrest.

Lumbar epidural morphine infusions for children undergoing cardiac surgery.
To determine whether outcomes and costs in children undergoing cardiac surgery are affected by the method of postoperative pain management. ⋯ Given the present methodologic limitations, the authors found improved outcomes only in LEM patients extubated late compared with IVO patients. Randomized, prospective studies to evaluate this conclusion and to determine the comparative efficacy and safety of LEM infusions are in progress.
