Effects of Minimal Dose Aprotinin on Blood Loss and Fibrinolytic System-Complement Activation in Coronary Artery Bypass Grafting Surgery

JOURNAL OF CARDIAC SURGERY, Issue 4 2006
Ferit Cicekcioglu M.D.
Methods: Forty-four patients scheduled for primary CABG were randomly assigned to the aprotinin (n = 24) or control group (n = 20). In aprotinin group, aprotinin was administered in two equal doses (before skin incision and added to the pump prime). Ventilation time, intensive care unit stay, mediastinal tube drainage, hospitalization, transfusion requirements, and postoperative morbidities and mortality were noted. Hematologic markers of fibrinolytic activity and complement activation were also measured pre- and postoperatively. Results: Although less mediastinal drainage occurred in aprotinin group, the difference was not statistically significant. Other postoperative variables like transfusion requirements, morbidities, and mortality were also found to be similar between groups. Among hematologic parameters, only postoperative levels of ,2-antiplasmin and plasminogen activator inhibitor-1 were significantly higher in aprotinin group. Conclusions: Although plasmin inhibitors begin to rise at this very low aprotinin dosage, it is not advisable to use this aprotinin regimen in CABG patients. [source]

Pleural fluid interleukin-8 and C-reactive protein for discriminating complicated non-purulent from uncomplicated parapneumonic effusions

RESPIROLOGY, Issue 1 2008
José M. PORCEL
Background and objective: This study was designed to test the hypothesis that measurement of IL-8 and CRP in pleural fluid could improve the identification of patients with non-purulent parapneumonic effusions that ultimately require chest tube drainage. Methods: We assessed IL-8, CRP and three classical parameters (pH, glucose and LDH) in the pleural fluid of 100 patients with parapneumonic effusions. Forty-nine of these patients had non-purulent complicated effusions (complicated parapneumonic pleural effusion, CPPE), and 51 had uncomplicated parapneumonic pleural effusions (UPPE). Receiver-operating characteristic curves were used to assess the sensitivity and specificity of pleural fluid biochemical parameters for differentiating among the two patient groups. IL-8 production was determined using a commercially available ELISA kit, and CRP was measured by immunoassay. Results: At a cutoff value of 1000 pg/mL, IL-8 differentiated CPPE from UPPE with a sensitivity of 84% and a specificity of 82%. Likewise, CRP levels were higher in CPPE than in UPPE, and showed 72% sensitivity and 71% specificity at a cutoff value of 80 mg/L. We found that all five pleural fluid tests showed similar diagnostic accuracies when evaluated by receiver-operating characteristic analysis. However, multivariate analysis indicated that the size of the effusion, as well as pleural fluid pH and IL-8 concentration, were the best discriminatory parameters, with likelihood ratios of 6.4, 4.4 and 3.9, respectively. Conclusions: Pleural fluid IL-8 is an accurate marker for the identification of non-purulent CPPE. [source]

Prospective evaluation of flex-rigid pleuroscopy for indeterminate pleural effusion: Accuracy, safety and outcome

RESPIROLOGY, Issue 6 2007
Pyng LEE
Objective: This study aimed to assess prospectively the accuracy, safety and outcome of flex-rigid pleuroscopy in the diagnosis of patients with indeterminate pleural effusions. Methods: Included in the study were all patients with unilateral exudative pleural effusions of unknown aetiology who underwent diagnostic flex-rigid pleuroscopy from July 2003 to June 2005, and were followed until December 2005. The procedure was conducted in the endoscopy suite under local anaesthesia and, where indicated, talc poudrage was carried out at the same time. Clinical data, length of hospitalization, chest tube drainage, outcome, diagnostic accuracy of pleuroscopy and procedure-related adverse events were recorded prospectively. Results: Fifty-one patients were recruited (20 male and 31 female). Median age was 53 years (range 45,67). Flex-rigid pleuroscopy was 96% accurate and yielded a diagnosis in 49 out of 51 patients. It was safely carried out without need for surgical intervention, blood transfusion or endotracheal intubation. Culture-negative fever was observed in eight patients (16%), and five patients (10%) required additional analgesia for postoperative pain. Duration of chest tube drainage and length of stay for patients who underwent diagnostic pleuroscopy were 1 and 2 days, respectively, while they were both 3 days when talc poudrage was carried out. Success rates with pleuroscopic talc pleurodesis for malignant pleural effusions were 94%, 92% and 89.5% at 3, 6 and 12 months, respectively, and the 30-day mortality was 0%. Conclusion: Flex-rigid pleuroscopy is a safe procedure with a high diagnostic accuracy and should be considered for the evaluation of indeterminate pleural effusion. [source]

Percutaneous transthoracic ventricular puncture for diagnostic and interventional catheterization

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 7 2008
D. Scott Lim MD
Abstract Objective: To describe our experience in a case series of patients requiring percutaneous direct ventricular puncture and sheath placement for diagnosis or intervention. Background: Access to the right or left ventricle for percutaneous interventions is limited in patients with mechanical prostheses in either the tricuspid, or mitral and aortic positions. Methods: After coronary angiography, direct ventricular puncture under ultrasound and fluoroscopic guidance was performed. At end of case, protamine was given to reverse the heparin, and sheaths were pulled with purse-string suture closure of the skin entrance. Results: For right ventricular access, 8- to 9-F sheaths were placed from subxiphoid approach in 2 patients to allow conduit and pulmonary artery interventions. For left ventricular access in patients with mitral and aortic prostheses, 4- to 8-F sheaths were placed from apical approach to allow diagnostic evaluation in 1 and interventions in 5 to occlude perivalvular mitral leaks and postoperative ventricular septal defect. Complication in one consisted of intercostal vein injury resulting in hemothorax requiring chest tube drainage. Conclusion: In this small cases series, direct ventricular puncture allowed the intervention to proceed with up to 9-F sheath size. Attention to puncture site relative to intercostal vascular anatomy is warranted. © 2008 Wiley-Liss, Inc. [source]
