Albumin, dextran, gelatin, and hydroxyethyl starch (HES) solutions are colloids that efficiently expand the circulating blood volume. The administration of colloids restores the intravascular volume with minimal risk of tissue edema in comparison with crystalloid solutions alone. However, colloids are always given for surgical and critically ill patients. ⋯ Rapidly degradable HES solutions have good hemodynamic effects, and the risk of adverse renal and coagulation effects, as well as allergic reactions, is minimal. The current investigation has also shown the beneficial effect of HES solution (especially HES 130/0.4) on inflammatory response, postoperative nausea and vomiting, and postoperative outcome. The indication of colloids with an assessment of the degree of hypovolemia and safety profiles should thus be taken into consideration before colloid administration.

ReviewAnesthetic considerations in diabetic patients. Part I: preoperative considerations of patients with diabetes mellitus.
Diabetes mellitus is an increasingly common disease that affects people of all ages, resulting in significant morbidity and mortality. Diabetic patients require perioperative care more frequently than their nondiabetic counterparts. The major risk factors for diabetics undergoing surgery are the associated end-organ diseases: cardiovascular disease, autonomic neuropathy, joint collagen tissue, and immune deficiency. Physicians need to pay extra attention to preoperative and preprocedure evaluation and treatment of these diseases to ensure optimal perioperative management.

ReviewPerioperative ischemic stroke in non-cardiovascular surgery patients.
Perioperative ischemic stroke occurs in approximately 0.08-0.7% of patients after non-cardiovascular surgery and confers a significant risk of morbidity and mortality. The mortality rate of this major complication is similar in non-cardiovascular and cardiovascular surgery. Its incidence appears to be similar in Japan, Europe, and the United States. ⋯ The 2009 Japanese guidelines for the management of stroke recommend using the appropriate intravenous infusions to avoid dehydration and consideration of anticoagulation in the patients who are at high risk for thrombosis and embolism while antithrombotic agents are discontinued. Understanding how to prevent perioperative ischemic stroke remains a challenge. In this article, we review the incidence, timing of the occurrence, mortality, risk factors, and pathophysiology of perioperative ischemic stroke in the non-cardiovascular surgery patient.

ReviewAnesthetic considerations in diabetic patients. Part II: intraoperative and postoperative management of patients with diabetes mellitus.
Some studies have reported that tight glycemic control in diabetic patients undergoing major surgery improves perioperative morbidity and mortality rates. Recently, however, large randomized studies have shown such control increases the mortality rate, since aggressive glycemic control induces more frequent incidences of hypoglycemia. Diabetic patients have cerebral complications during the perioperative period more often than their nondiabetic counterparts. ⋯ Hence, anesthesiologists should have adequate knowledge about anesthetic agents that maintain the integrity of the cerebral circulation. Patients with diabetes mellitus (DM) have an increased susceptibility to perioperative infections. Recent work confirmed that a combination of intravenous and subcutaneous insulin as a glucose management strategy had beneficial effects identical with intravenous insulin therapy alone on the reduction of infection rates during the postoperative period.
