Does the choice of intraoperative fluid modify abdominal aneurysm repair outcomes?: A cohort analysis.

Intraoperatively administered hydroxyethyl starch could be a risk indicator for postoperative acute kidney injury (AKI) in vascular surgical patients.In a single-center retrospective cohort analysis, we assessed the impact of hydroxyethyl starch and other risk indicators on AKI and mortality in 1095 patients undergoing elective open abdominal aneurysm repair (AAA-OR) or endovascular aortic repair (EVAR). We established logistic regression models to determine the effect of various risk indicators, including hydroxyethyl starch, on AKI, as well as Cox proportional hazard models to assess the effect on mortality.

Cancellation of Elective Cases in a Recently Opened, Tertiary/Quaternary-Level Hospital in the Middle East.

Case cancellations have a negative financial impact due to revenue loss and the potential costs of underutilized time. The goals of this study at a recently opened hospital in the Middle East were to measure the cancellation rates for elective surgical or endoscopic cases and to identify the reasons for cancellation. During the 1-month study period, 170 (22.

S-nitroso human serum albumin reduces ischaemia/reperfusion injury in the pig heart after unprotected warm ischaemia.

Aims: Uncoupled endothelial nitric oxide synthase (eNOS) is a major contributor to vascular reactive oxygen species generation in ischaemia/reperfusion (I/R) injury. Supplementation of NO by the novel NO donor S-nitroso human serum albumin (S-NO-HSA) may inhibit uncoupling of eNOS (feedback inhibition).

Methods And Results: Pigs (n = 14; 33.

S-nitroso human serum albumin improves oxygen metabolism during reperfusion after severe myocardial ischemia.

Nitric oxide (NO) supplementation may modify myocardial oxygen consumption and vascular function after ischemia. We investigated the effects of the NO donor, S-nitroso human serum albumin (S-NO-HSA), on cardiac oxygen metabolism during controlled reperfusion on normothermic cardiopulmonary bypass after severe myocardial ischemia. Pigs randomly received either S-NO-HSA or human serum albumin prior to and throughout global myocardial ischemia.

Weaning of rotary blood pump recipients after myocardial recovery: a computer study of changes in cardiac energetics.

Background: Weaning of patients from mechanical cardiac support after myocardial recovery has always involved multiple, interacting factors, particularly the training of the myocardium during reduction of pump flow. Rotary pumps offer training advantages when support flow is reduced, even to nearly zero. We report a computer analysis that evaluates the work required of the heart during partial unloading and removal of rotary pumps.
