ReviewBleeding and thrombosis in intensive care patients with thrombocytopenia-Protocol for a topical systematic review.
Thrombocytopenia is a common condition in critically ill patients in the intensive care unit (ICU). It is associated with prolonged stay in the ICU, increased transfusion requirements, risk of bleeding and mortality. The evidence regarding the use of prophylactic platelet transfusion and thrombosis prophylaxis in patients with thrombocytopenia in the ICU is unknown. To direct future research, we aim to assess the current evidence regarding prophylactic platelet transfusion and thrombosis prophylaxis on patient-important benefits and harms in the ICU population. ⋯ The outlined topical systematic review will provide important data on the benefits and harms of prophylactic platelet transfusion and thrombosis prophylaxis in ICU patients with thrombocytopenia and provide estimates on the rate of thrombocytopenia in this vulnerable population.

ReviewIatrogenic cerebral gas embolism-A systematic review of case reports.
Cerebral gas embolism is a complication of several medical procedures and occurs when gas enters the cerebral circulation. Knowledge about etiology and outcome in affected patients is limited, and prospective trials on management and treatment are hardly feasible. Case reports are therefore an important source of information. ⋯ The reported causes, symptoms and signs, and outcomes of ICGE vary significantly, and awareness of the condition in the medical community is essential. A standardized method of reporting could facilitate higher quality research in the field.

Review Meta AnalysisThe effects of general anaesthesia on oxygen consumption: A meta-analysis guiding future studies on perioperative oxygen transport.
Increased oxygen extraction, the ratio of consumption to delivery, has been associated with poor outcome after surgery. Oxygen consumption (VO2) can change in several ways in the perioperative period, but is seldom monitored directly in routine care. This study investigates the effects of general anaesthesia on VO2. ⋯ General anaesthesia probably reduces oxygen consumption but the effect estimate is uncertain. Given the limited generalizability and low quality of the available evidence, new studies in modern perioperative settings and in today's older high-risk surgical patient populations are needed.

ReviewEndorsement of clinical practice guidelines by the Scandinavian Society of Anaesthesiology and Intensive Care Medicine.
Clinical practice guidelines from other organizations or societies with assumed clinical and contextualized relevance for Scandinavian Society of Anaesthesiology and Intensive Care Medicine (SSAI) members, may trigger a formal evaluation by The Clinical Practice Committee (CPC) for possible SSAI endorsement. This avoids unnecessary duplicate processes and minimizes resource-waste. ⋯ The results of the assessment, including the decision to endorse or not, are presented to the SSAI Board for sanctioning. This document briefly outlines the process for evaluation of non-SSAI guidelines by the CPC for possible SSAI endorsement.

Randomized Controlled TrialAssociation between perioperative hyperoxia and cerebrovascular complications after laparotomy-A post-hoc follow-up study.
Perioperative hyperoxia has been linked to increased long-term mortality. Vasoconstrictive and cellular side effects to hyperoxia have been suggested to increase the risk of coronary and cerebral ischemia. The aim of this post-hoc analysis of a large randomized trial was to compare the effects of 80% vs 30% perioperative oxygen on the long-term risk of stroke or transient cerebral ischemia (TCI) in patients undergoing abdominal surgery. ⋯ Stroke or TCI did not seem related to perioperative inspiratory oxygen fraction. Due to few events, this study cannot exclude that perioperative hyperoxia increases risk of mortality, stroke, or TCI after abdominal surgery.
