Evaluating the Child with Purpura - Article
ABSTRACT: Purpura is the result of hemorrhage into the skin or mucosal membrane. It may represent a relatively benign condition or herald the presence of a serious underlying disorder. Purpura may be secondary to thrombocytopenia, platelet dysfunction, coagulation factor deficiency or vascular defect. Investigation to confirm a diagnosis or to seek reassurance is important. Frequently, the diagnosis can be established on the basis of a careful history and physical examination, and a few key laboratory tests. Indicated tests include a complete blood cell count with platelet count, a peripheral blood smear, and prothrombin and activated partial thromboplastin times.
ABSTRACT: Patients with chronic kidney disease often require surgical interventions for vascular access and for medical problems related to comorbid conditions. Perioperative morbidity and mortality rates are increased in these patients. Preoperative attention to common medical problems that occur in patients with impaired renal function can lower some surgical risks. Hyperkalemia can be temporarily improved by the intravenous administration of an insulin-dextrose combination or bicarbonate, and polystyrene binding resins or dialysis can remove excess stores of potassium. Increased bleeding related to uremic platelet dysfunction can be managed by the administration of desmopressin, cryoprecipitate, or estrogens, and by avoiding the use of medications with antiplatelet effects close to the time of surgery. Transfusions of red blood cells should be reserved for use in patients with clinically significant anemia, because antibody formation may decrease the likelihood of successful renal transplantation in the future. Cardiovascular disease is the most common cause of death in patients with renal disease. Patients with chronic kidney disease may have hypertension and hypoglycemia in the perioperative period. Preoperative testing may be necessary in patients with cardiac risk factors. If future vascular access grafting is contemplated, intravenous line placement and blood draws should be avoided in a patient's nondominant arm.
