ReviewThe effect of insulin therapy algorithms on blood glucose levels in patients following cardiac surgery: A systematic review.
A number of insulin infusion algorithms, with varying methods and effects, have been developed to guide the management of postoperative hyperglycemia in critically ill patients. ⋯ Future studies to compare the methods of computer calculator directed CII to paper nomogram directed CII should be undertaken using more rigorous research designs such as randomized controlled trials with sufficiently powered sample sizes. Definitions for both hypoglycemia and hyperglycemia should be standardized.

Observational Study
Using clinical parameters to guide fluid therapy in high-risk thoracic surgery. A retrospective, observational study.
Despite extensive research, the debate continues as to the optimal way of guiding intraoperative and postoperative fluid therapy. In 2009 we changed our institutional guideline for perioperative fluid therapy in patients undergoing extrapleural pneumonectomy (EPP) and implemented the use of central venous oxygen saturation and intended low urine output to guide therapy in the early postoperative period. Here we evaluate the consequences of our changes. ⋯ The use of clinical parameters to balance fluid restriction and a sufficient circulation in patients undergoing EPP was associated with a reduction in mean LOSI without increasing the incidence of postoperative complications. Due to methodological limitations these results are only hypothesis generating.

ReviewOptimal technique for deep breathing exercises after cardiac surgery.
Cardiac surgery patients often develop a restrictive pulmonary impairment and gas exchange abnormalities in the early postoperative period. Chest physiotherapy is routinely prescribed in order to reduce or prevent these complications. Besides early mobilization, positioning and shoulder girdle exercises, various breathing exercises have been implemented as a major component of postoperative care. ⋯ Arbitrary instructions are given, and recommendations on performance and duration vary between hospitals. Deep breathing exercises are a major part of this therapy, but scientific evidence for the efficacy has been lacking until recently, and there is a lack of trials describing how postoperative breathing exercises actually should be performed. The purpose of this review is to provide a brief overview of postoperative breathing exercises for patients undergoing cardiac surgery via sternotomy, and to discuss and suggest an optimal technique for the performance of deep breathing exercises.

Review Case Reports
Valsalva hemorrhagic retinopathy presenting as a rare cause of impaired vision after a general anesthetic-a case report and review of the literature.
Postoperative visual loss from any cause is potentially catastrophic. We present a case of Valsalva hemorrhagic retinopathy (VHR) as a rare cause of impaired vision after an apparently uneventful general anesthetic. ⋯ Although VHR is considered to be rare, the events and activities with which it is associated are relatively common, both in everyday life and in the operating room. We suggest that the occurrence of VHR after anesthesia and surgery may be more frequent than previously appreciated and make recommendations for further investigations.
