“…For example, the report of the Dialysis Outcomes and Practice Patterns Study (DOPPS) work group showed that the types of vascular access used in maintenance hemodialysis patients were quite different in the US, Japan, and European countries (6). The ratio found in the present study was compatible with the ratio documented in original clinical papers from Japan and European countries (7,8).…”

The objective of the present study was to investigate whether patient age is associated with vascular access failure during maintenance hemodialysis. Thus, patients who had a successful permanent hemodialysis vascular access installed (Group N: 314 cases), and those who required vascular access revision (Group R: 108 patients) were studied. To assess the association between patient age and the risk of vascular access failure, Cox proportional hazards regression was used to determine hazard ratios (HR) and 95% confidence intervals (CI). We found that in Group N, the significant risk factors were age, gender, and diabetes mellitus (95% CI: 1.004-1.013, 0.380-0.827, 1.279-2.859). Using a univariate analysis model, significant hazard ratios (HR) were found with ages of 60 (CI: 1.062-2.302), 65 (CI: 1.052-2.280), and 70 (CI: 1.082-2.537) years, with the largest HR at 70 years of age (HR: 1.657). In contrast, in Group R, multivariate analysis using Cox proportional hazards identified only one prognostic variable, the location of the vascular access. In Group R, univariate analysis models showed that age was not a significant factor. We conclude that our data show that age is a risk factor for the successful maintenance of initial permanent hemodialysis vascular access. Other risk factors include gender and diabetes mellitus. However, these factors were not related to the successful maintenance of revised vascular access.

“…A variation in the SvO 2 method has been described both in animal models 19 and in neonates 9 receiving venovenous ECMO via dual-lumen cannulae, with recirculation assessed in the neonate study at the end of each ECMO run when the subjects could tolerate suspension of sweep gas flow. 9 SvO 2 was first measured with the sweep gas flow turned off ("SvO 2 ") and again with sweep gas set at 100% oxygen ("SQO 2 ").…”

Recirculation in Venovenous Extracorporeal Membrane Oxygenation

2015

Recirculation, a phenomenon in which reinfused oxygenated blood is withdrawn by the drainage cannula without passing through the systemic circulation, decreases the efficiency with which venovenous extracorporeal membrane oxygenation (ECMO) provides oxygenation. The precise amount of recirculation may be difficult to quantify. However, interventions should be attempted to reduce recirculation when oxygen delivery is suboptimal and recirculation is suspected. Several techniques, including the use of dual-lumen cannulae, have been successful in minimizing recirculation in venovenous ECMO. This article will provide an overview of the factors that affect recirculation, methods that may be used to quantify recirculation, and interventions that may reduce recirculation, thereby increasing ECMO efficiency.

It preserves the patient's life by providing the adequate oxygen supply and blood flow to the vital organs.…”

The Effects of Pulsatile versus Non-Pulsatile Extracorporeal Circulation on the Pattern of Coronary Artery Blood Flow during Cardiac Arrest

Background In sudden cardiac arrest, the effective maintenance of coronary artery blood flow is of paramount importance for myocardial preservation as well as cardiac recovery and patient survival. The purpose of this study was to directly compare the effects of pulsatile versus non-pulsatile circulation to coronary artery flow and myocardial preservation in a cardiac arrest condition. Methods A cardiopulmonary bypass circuit was constructed in a ventricular fibrillation model using fourteen Yorkshire swine weighing 25–35 kg each. The animals were randomly assigned to group I (n=7, non-pulsatile centrifugal pump) or group II (n=7, pulsatile T-PLS pump). Extracorporeal circulation was maintained for two hours at a pump flow of 2 L/min. The left anterior descending coronary artery flow was measured with an ultrasonic coronary artery flow measurement system at baseline (before bypass) and at every 20 minutes after bypass. Serologic parameters were collected simultaneously at baseline, 1 hour, and 2 hours after bypass in the systemic arterial and coronary sinus venous blood. The Mann-Whitney U test of STATISTICA 6.0 was used to determine intergroup significances using a p value of < 0.05. Results The resistance index of the coronary artery was lower in group II and the difference was significant at 40 min, 80 min, 100 min and 120 min (p < 0.05). The mean velocity of the coronary artery was higher in group II throughout the study, and the difference was significant from 20 min after starting the pump (p < 0.05). The coronary artery blood flow was higher in group II throughout the study, and the difference was significant from 40 min to 120 min (p < 0.05) except at 80min. Serologic parameters showed no differences between the groups at 1 hour and 2 hours after bypass in the systemic and coronary sinus blood (p=NS). Conclusion In the cardiac arrest condition, pulsatile extracorporeal circulation provides more blood flow, higher flow velocity and less resistance to coronary artery than non-pulsatile circulation.
