We hypothesized that this variability may, in part, be related to the use of cardiotomy suction (CS), which has been demonstrated to reintroduce pro-coagulant and pro-inflammatory factors into the systemic circulation during CPB. A prospective, randomized study was undertaken to evaluate the specific effects of CS. Methods: Thirty-six patients undergoing first-time, non-emergent, coronary artery bypass graft surgery with CPB were randomized to one of three treatment groups: I) non-heparin bonded circuits with the use of CS (n = 12), II) Duraflo-II HBC with CS (n = 12), or III) Duraflo-II HBC without CS (n = 12). Thrombin generation (PF1.2), neutrophil activation (PMN elastase, PMN-E), platelet activation ( (cid:1) -thromboglobulin, (cid:1) -TG) and neuronal injury (neuron-specific enolase, NSE) were analyzed by ELISA assays post CPB and compared to pre bypass levels. Results are presented as mean ± SEM. Results: Pre bypass levels of all markers were similar amongst treatment groups.","PeriodicalId":309024,"journal":{"name":"The Journal of ExtraCorporeal Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122856107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CPB is a known contributor to platelet loss and platelet dysfunction leading to disruption of hemostasis. Impaired hemostasis results in excess bleeding in 5–25% of all patients undergoing CPB. For this reason, it may be beneficial to measure platelet number and function in these patients. The purpose of this study was to compare the Plateletworks™ platelet function analyzer to the thromboelastograph (TEG) in predicting postoperatiave hemostatic outcomes as measured by blood product use and chest tube (CT) drainage. This study consisted of 35 adult patients undergoing cardiac surgery with cardiopulmonary bypass at Rush-Presbyterian-Saint Luke’s Medical Center (RPSLMC). The Plateletworks™ and TEG tests were performed preoperatively, after protamine was given, and 24 hours postoperatively on all patients. Plateletworks™ demonstrated a statistically significant change in platelet function as shown by the adenosine diphosphate (ADP) reagent tube from the preoperative period to the removal of the aortic cross clamp (p = .011). The TEG did not demonstrate a significant change in the k-time and maximum amplitude (MA), but did show a significant change in the alpha-angle from the pre-operative to postoperatiave sample (p = .035). A correlation was found between Plateletworks™ collagen reagent tubes preoperatively and CT drainage (p = .048, r −0.324). No statistical correlation was established between TEG parameters and CT drainage at any time interval. TEG preoperative MA showed a correlation to receipt of blood products (p = .016). When comparing the Plateletworks™ to the TEG in this study, the Plateletworks™ system was a more useful predictor of blood product use and chest tube drainage.","PeriodicalId":309024,"journal":{"name":"The Journal of ExtraCorporeal Technology","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124497554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hallmark feature of the aged myocardium is increased fibrosis resulting in diastolic dysfunction. Moreover, the survival of patients subsequent to a myocardial infarction is inversely related to age because of a certain extent to maladaptive remodeling mediated by cardiac fibroblasts. Our hypothesis is that cardiac fibroblast (CF) dysfunction results in overexpressed TGF-β1 leading to increased cardiac collagen content in the aged population. TGF-β1 stimulates the synthesis of the extracellular matrix proteins, including collagen in the cardiac tissues. The RT–PCR analysis of mRNA expression of TGF-β1 of the CF was increased by 43% in the aged mice as compared to the younger. The stiffness of the left ventricle is expressed with the slope of the end-diastolic pressure-volume relationship parameter, (mmHg/L). In a mouse model, we demonstrated that was 0.30 ± 0.05 in the young as compared to 0.52 ± 0.10 in the aged (p < .05). The ventricular stiffness was associated with the myocardial collagen content; namely, young versus the aged was 9.5 ± 4.0 as compared to 16.4 ± 2.3% of total protein, respectively (p < .05). In conclusion, the gene structure–function relationships support our hypothesis that cardiac fibroblast disregulation contributes to diastolic filling dysfunction in elderly persons. These data provide a potential contributory mechanism for diastolic dysfunction that may be vital in caring for the aged open-heart surgical patient.","PeriodicalId":309024,"journal":{"name":"The Journal of ExtraCorporeal Technology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126152460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to examine the effect of poly(2-methoxyethylacrylate) coating (PMEA, X-Coating™) on coagulation and inflammation under various prime conditions. An in vitro analysis was conducted utilizing fresh whole human blood (2 units) and a CPB circuit (n 18) consisting of a venous reservoir, oxygenator, and arterial filter. Nine nontreated circuits were used in a control group (CTR) and an equal number of tip-to-tip PMEA circuits for treatment (TRT). Each group was divided into three subgroups based upon prime: crystalloid, hetastarch (6%), and albumin (5%). CPB was conducted with a hematocrit 30% ± 2, temperature 37°C ± 1, and a flow of 4L/min. Samples were collected at 0, 60, 120, and 240 minute intervals. Endpoint measurements included thromboelastograph index (TI), and markers of inflammation and coagulation. The TI was significantly depressed in both groups when hetastarch was used in the prime. The TRT had significantly higher TI levels in both the crystalloid (0.3 ± 0.1 vs. −3.3±[1.2, P < .05) and albumin (0.6 ± 0.2 vs−3.9± −1.1. P < .03) subgroups compared to CTR groups. Platelet count was significantly higher in TRT as compared to CTR groups, except for both hetastarch groups. SEM demonstrated significant fibrin deposition on nontreated circuitry but little to no detection in the TRT group. In conclusion, both surface coating and prime components significantly effect coagulation, with PMEA circuits resulting in more favorable preservation of function.","PeriodicalId":309024,"journal":{"name":"The Journal of ExtraCorporeal Technology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132855603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study consisted of 98 consecutive patients randomly assigned to either a CPB circuit that consisted of a Trillium-coated Affinity open reservoir oxygenator or a CPB circuit with an uncoated Affinity open reservoir oxygenator. The operative procedure performed on all 98 patients consisted of either coronary artery bypass graft (CABG), valve, or a combination of the two. Exclusion criteria consisted of patients who presented to the operating room in circulatory arrest. Trillium biopassive surface coating resulted in improved clinical outcomes and fewer adverse events when compared to the control group. Significantly, fewer patients required no blood products (18.3% in the control group vs. 32.7% in the treatment group), even though the control group had a significantly higher pre-bypass hematocrit. Postoperative atrial fibrillation (24.5% vs. 16.3%) and reoperation for bleeding (10.2% vs. 4.1%) showed a much lower incidence in the Trillium group. Significance was not reached because of the small sample size resulting in low power.
