  • Comparison of Clinical Applications Between Two Different Extracorporeal Membrane Oxygenation Systems

    Abstract: Objective To summarize the clinical experiences of performing extracorporeal membrane oxygenation (ECMO) on patients with heart and respiratory failure, and compare the clinical outcomes of Medtronic system and Quadrox PLS system. Methods We retrospectively analyzed the clinical data of 121 heart and respiratory failure patients who underwent ECMO treatment in Fu Wai Hospital from December 2004 to December 2009. Based on the different systems used, 121 patients were divided into two groups. In group M, there were 65 patients including 41 males and 24 females, with an age of 26.6±25.9 years; and they accepted Medtronic ECMO system treatment. In group Q, there were 56 patients including 39 males and 17 females, with an age of 32.4±23.9 years and they underwent Quadrox PLS ECMO system treatment. The evaluation of the clinical outcomes of these two different systems was based on the comparison of transmembrane pressure drop (TMPD), anticoagulation, hemolysis, plasma leakage, organ function, complication and hospital mortality between the two groups. Results Compared with group M, ECMO with Quadrox PLS system was associated with lower TMPD (at the beginning of ECMO: 15.0±6.0 mm Hg vs.28.0±5.0 mm Hg, P=0.000; 24 hours later: 16.0±5.0 mm Hg vs. 30.0±7.0 mm Hg, P=0.000) and less thrombus formation(7.1% vs.23.1%, P=0.037), less plasma leakage (0.0% vs. 50.8%, P=0.000), less hemolysis (14.3% vs. 29.2%, P=0.047). There were no significant differences between the two groups in support duration, complication rate, and hospital mortality(Pgt;0.05). Conclusion Both devices have similar effects for safe clinical application, but Quadrox PLS ECMO system has a relatively high biocompatibility with lower TMPD, less plasma leakage, and thrombus formation.

  • Plasma Exchange for Severe Haemolysis During ReCardiopulmonary Bypass to Patients with Cardiac Surgery

    Abstract: Objective To summarize the clinical experience of plasma exchange (PE) during recardiopulmonary bypass (CPB) of patients with severe haemolysis in cardiac surgery. Methods Between January 2001 and December 2005, five patients required PE for severe haemolysis after cardiac surgery. There were periprosthetic leakage and infective endocarditis in 3 patients, congenital heart disease of pulmonary artery stenosis with unsatisfied right ventricular outflow tract patching in 1 patient and thrombosis during extracorporeal membrane oxygenation (ECMO) in 1 patient. They all need blood purification to avoid acute renal failure. Results Five patients were successfully treated with PE during CPB without major complications. The amount of plasma and blood transfused in the 5 patients were 2.2±0.8L and 0.6±0.3L respectively. The volume of plasma exchange and ultrafiltrate were 3.9±1.8L and 2.4±1.3L respectively.The electrolytes and bloodgas analysis in all patients were maintained at the normal levels. The hemodynamics was stable. After heart resuscitation CPB stopped smoothly. Disappearance of periprosthetic leakage and satisfaction of right ventricular outflow tract patching were observed by echocardiograms after peration.Extubation was performed 24h after the operation in 5 patients, and they were discharged 12 to 53 d after the operation with fully recovery. The urine was clear and the body temperature was normal. Before they left thehospital, the concentration of free hemoglobin was tested in 3 patients. The concentration of free hemoglobin was slightly higher in 1 patient (68mg/L), and normal in 2 patients (lt;40mg/L). Conclusion PE during CPB in severe haemolysis is a safe technique which can effectively prevent acute renal failure caused by severe mechanical haemolysis after cardiac surgery.

  • Intravenous Immunoglobulin G for Hemolytic Disease of the Newborn: A Systematic Review

    Objective To assess the effectiveness of intravenous immunoglobulin G (IVIG) in reducing the need for exchange transfusion in neonates with proven haemolytic disease due to Rh and/or ABO incompatibility. To evaluate the effectiveness of IVIG in reducing the duration of phototherapy and hospital stay. Methods We electronically searched CENTRAL, MEDLINE (1966 to May 2008), EMBASE (1992 to May 2008), CBMdisc (November 1979 to May 2008), and also checked the reference lists of all papers identified. According to the Cochrane Handbook for Systematic Reviews of interventions, randomized controlled trials comparing IVIG and phototherapy with phototherapy alone in neonates with Rh and/or ABO incompatibility were identified and analyzed. Results Six RCTs were included. The meta-analysis showed that, IVIG can significantly decrease the requirements of exchange transfusion (RR=0.27, 95%CI 0.18 to 0.42), the duration of hospitalization (WMD= –1.11, 95%CI –1.60 to –0.63) and the duration of phototherapy (WMD= –0.82, 95%CI –1.16 to –0.47). Conclusions Intravenous immunoglobulin (IVIG) is recommended for treating hemolytic disease of the newborn because it is effective in decreasing the requirements of exchange transfusion, the duration of hospitalization and phototherapy. Well designed studies with large sample in multi-center are required for further proving.

  • The Clinical Application of Lysophosphatidic Acid for Cerebral Ischemic Stroke: A Systematic Review

    Objective To assess the clinical application of lysophosphatidic acid (LPA) as the early warning index for cerebral ischemic stroke (CIS). Methods Trials were collected through electronic searches of PubMed, The Cochrane Library, CBM, CNKI, Wanfang, and VIP (from the date of database establishment to June 2009). We screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of the included studies, performed descriptive analysis and meta-analysis with The Cochrane Collaboration’s RevMan 4.2 software. Results A total of 22 studies were included. The results of meta-analyses showed that, there was a significant difference about LPA level in cerebral infarction (CI) group vs. healthy control group (WMD=2.00, 95%CI 1.85 to 2.15), and in transient ischemia attach (TIA) group vs. healthy control group (WMD=2.48, 95%CI 2.18 to 2.78); and a difference was noted about 24 hours LPA level in CI group vs. healthy control group (WMD=2.40, 95%CI 1.81 to 2.99). Conclusions According to the included studies, the contents of LPA is higher in CIS than that in healthy control group. It would be helpful to measure LPA in the TIA period for intervention. However, more high quality trials are expected for further study, in order to prove the value of LPA as early warning index because of the heterogeneity and poor quality of the current included studies.
