Randomized Controlled Trial Comparative StudyGlucose response during craniotomy: propofol-remifentanil versus isoflurane-remifentanil.
Major surgery is associated with a stress response. The aim of this study was to compare the effects of isoflurane or propofol, both supplemented with remifentanil, on the glucose, cortisol and insulin-based stress responses prospectively. ⋯ Isoflurane and propofol, both combined with remifentanil, provided clinically comparable cortisol and insulin responses to surgery in craniotomy operations, whereas propofol attenuated the increase in plasma blood glucose.

ReviewUse of synthetic colloids in sepsis: a critical review on efficacy, safety and patient benefits.
In this narrative review, the studies and analyses are discussed that pertain to benefits and detriments of synthetic colloids versus natural colloids or crystalloids used for fluid resuscitation in sepsis and septic shock. The relative amount of fluid infusions used to reach clinical or hemodynamic end-points are reviewed, as well as potential toxicity of starch solutions on the kidney. Hence, it cannot be excluded that adverse effects partly offset beneficial hemodynamic effects that are similar to that of natural colloids, so that in most analyses a mortality benefit of synthetic colloid fluid resuscitation in sepsis and septic shock cannot be demonstrated.

Renal support, intended as a refined and context-sensitive form of severe acute kidney injury management, might be achieved by administering renal replacement therapy with the correct timing and indication, correct prescription and, also, by the expertise and capacity of clinicians to tailor different RRTs to different patients. Furthermore, technical evolution and extended indications for extracorporeal treatments, currently allow the support of multiple organs, other than the isolated kidney failure. Unfortunately, current literature in the field of optimal management of severe acute kidney injury is controversial and lacks a standard of care. This review aims to describe the recent clinical, scientific and technical evolution of renal replacement therapy and the potential suggestive concept of multiple organ support therapy.

Fluid resuscitation is an essential aspect of the management of patients with severe sepsis and septic shock, especially in the early stages of disease. Which fluid should be used for this purpose has been a topic of ongoing and sometimes heated debate for many years, yet this is still little evidence to support one fluid over another. ⋯ In this article, we will review the advantages and limitations of the key fluid types currently used for the resuscitation of critically ill patients with sepsis, including the crystalloids (saline solutions and Ringer's lactate), and the colloids (albumin, gelatins, dextrans, and hydroxyethyl starches). We will then briefly summarize the limited evidence to support use of one fluid type over another, and provide general suggestions for fluid use in these patients.

Case ReportsAn unusual cause of delayed awakening following coronary artery surgery.
Neurological deficits are a frequent complication of adult cardiac surgery. Dandy-Walker malformation (DWM) is a rare posterior fossa malformation defined by hypoplasia and upward rotation of the cerebellar vermis, cystic dilation of the fourth ventricle and, on occasion, hydrocephalus. We report an incidental diagnosis of DWM in an adult following coronary artery surgery complicated by delayed awakening.
