Multicenter Study Comparative Study
The use of APACHE III to evaluate ICU length of stay, resource use, and mortality after coronary artery by-pass surgery.
To identify patient characteristics that are associated with increased ICU length of stay, resource use, and hospital mortality after coronary artery bypass surgery. ⋯ A limited number of operative characteristics, the post-operative acute physiology score (APS) of APACHE III and patient demographic data can predict hospital death rate, ICU length of stay, and resource use immediately following coronary by-pass surgery. These estimates may compliment assessments based on pre-operative risk factors in order to more precisely evaluate and improve the efficacy and efficiency of cardiovascular surgery.

Comparative Study
Current strategy of circulatory support for profound heart failure.
The purpose of this study is to assess the current strategy of mechanical circulatory support for profound heart failure. In the last 10 years, 37 patients with profound heart failure underwent mechanical circulatory support after open heart surgery and 9 patients with non-cardiotomy cardiogenic shock received emergency circulatory support. All patients showed severe cardiac failure and/or fatal ventricular arrhythmia and required circulatory support as a life-saving measure. ⋯ And 9 patients with non-cardiotomy cardiogenic shock received percutaneous cardiopulmonary support (or PCPS) as an emergency assist system. Weaning and discharge rates of the patients by the type of circulatory supports were 41.7% and 25.0% with VAB, 69.3% and 46.2% with BVB, 87.5% and 37.5% with LVB, 75.0% and 50.0% with LVAD, and 44.4% and 11.1% with PCPS, respectively. Clinical results of post-cardiotomy circulatory support (64.9% of weaning and 37.8% of discharge) were acceptable, but the patients with non-cardiotomy cardiac failure needed early application of more advanced circulatory support.

To evaluate changes in and the correlation between plasma phosphorus, red cell 2,3-diphosphoglycerate (DPG) and adenosine triphosphate (ATP), and P50 in children following heart surgery. ⋯ Reduction in red cell 2,3-DPG, P50, and plasma phosphorus occurs after open heart surgery in children. These changes can potentially contribute to impaired oxygen utilization in the postoperative period, when adequacy of tissue oxygenation is critical.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial
Crystalloid versus blood cardioplegia in coronary by-pass surgery. A prospective, randomized, controlled study in 100 consecutive adults.
In a prospective randomized trial we investigated the benefit of blood versus asanguinous cardioplegia in routine coronary by-pass grafting. One hundred consecutive adult patients were randomly assigned to two groups: Group A (53 patients) received cold blood cardioplegia and group B (47 patients) had standard St. Thomas solution. ⋯ Hospital stay did not differ between the two groups. In this clinical trial we could demonstrate the superiority of blood versus crystalloid cardioplegia in routine coronary by-pass grafting. Ante- and retrograde delivery of cold blood cardioplegia followed by warm reperfusion is a safe and simple method yielding satisfactory results.

Chronic post-thoracotomy pain (CPP) is a vexing clinical problem whose management has received scant attention. In order to identify the risk factors associated with CPP and determine the optimal treatment, the records of 238 consecutive patients who underwent thoracotomy were reviewed. CPP was defined as discomfort requiring the regular administration of analgesics that continued more than three months following surgery. ⋯ All were found to have tumor regrowth. We conclude that CPP occurs more commonly following chest-wall resection and pleurectomy, and that preoperative narcotic use is a predictor of CPP. Worsening pain following initial relief should prompt a vigorous search for recurrent cancer.
