BACKGROUND Perioperative cardiovascular events in renal transplantation are common and non-invasive cardiac stress tests are recommended in high-risk renal transplant candidates. In 2004, we introduced a standardized preoperative cardiac risk assessment programme with the aim of reducing perioperative cardiac events. METHODS Since 2004, all asymptomatic high-risk renal transplant candidates h...

background: we observed the clinical effects of comprehensive nursing intervention pattern in 23g minimally invasive vitreous surgery according to the comprehensive nursing intervention table developed by our hospital, which would supply a basis for its clinical application. methods: in this prospective study, we followed 120 patients undergoing 23g minimally invasive vitreous surgery from xuzh...

OBJECTIVE To evaluate the discriminatory value and compare the predictive performance of six non-invasive tests used for perioperative cardiac risk stratification in patients undergoing major vascular surgery. DESIGN Meta-analysis of published reports. METHODS Eight studies on ambulatory electrocardiography, seven on exercise electrocardiography, eight on radionuclide ventriculography, 23 o...

Introduction The coagulation cascade is a dynamic process dependent on many factors. It involves interaction between primary hemostasis, platelet clot formation, secondary hemostasis, thrombin generation, and fibrinolysis. The assessment of this process is particularly important in the surgical patient to properly assess patient coagulation assessment, manage hemostatic therapy and transfusion ...

BACKGROUND Nurses' recognition of their own level of skills and abilities (ie perceived competence) is a prerequisite for ensuring they can practice in a safe manner. The demand for competence, in the operating room, may vary between clinical environments. It is, however, unclear what competency levels migrating nurses need in order to be deemed safe. AIM This paper describes Canadian and Aus...

BACKGROUND Four randomized trials have evaluated the impact of supplemental perioperative oxygen on the incidence of surgical site infections (SSIs), with mixed results. The objectives of this meta-analysis were: (1) To evaluate further the effect of supplemental perioperative oxygen on SSIs after colorectal surgery; and (2) to generate a strategy for future studies to determine definitively th...

Low molecular weight heparins were first introduced in the United States in May 1993 as an alternative to currently available anticoagulant therapy. Like standard heparin, these anticoagulants inhibit activation of a number of coagulation enzymes, but low molecular weight heparins have their primary inhibitory effect on factor Xa. A decrease in plasma protein binding by low molecular weight hep...

OBJECTIVE Perioperative morbidity and mortality in patients receiving pneumonectomy because of non-small cell lung cancer (NSCLC) remains quite high. The aim of this study is to identify risk factors to minimize perioperative mortality and morbidity. PATIENTS AND METHOD The results of 156 Patients who received pneumonectomy between 1995 and 2004 were reviewed retrospectively. All patients had...

Unselected coagulation testing is widely practiced in the process of assessing bleeding risk prior to surgery. This may delay surgery inappropriately and cause unnecessary concern in patients who are found to have 'abnormal' tests. In addition it is associated with a significant cost. This systematic review was performed to determine whether patient bleeding history and unselected coagulation t...

The current standards for preoperative cardiac evaluation and the guidelines published by the American College of Cardiology and the American Heart Association call for noninvasive or invasive cardiac evaluation in certain patients. Perioperative use of beta-adrenergic blockade has been shown to reduce cardiac complication rates, diminishing the positive predictive value and the likelihood rati...
