Meta AnalysisFibrinogen Concentrate in Cardiovascular Surgery: A Meta-analysis of Randomized Controlled Trials.
Postoperative bleeding remains a frequent complication after cardiovascular surgery and may contribute to serious morbidity and mortality. Observational studies have suggested a relationship between low endogenous plasma fibrinogen concentration and increased risk of postoperative blood loss in cardiac surgery. Although the transfusion of fibrinogen concentrate has been increasing, potential benefits and risks associated with perioperative fibrinogen supplementation in cardiovascular surgery are not fully understood. ⋯ Current evidence remains insufficient to support or refute routine perioperative administration of fibrinogen concentrate in patients undergoing cardiovascular surgery. Fibrinogen concentrate may reduce the need for additional allogeneic blood product transfusion in cardiovascular surgery patients at high risk or with evidence of bleeding. However, no definitive advantage was found for reduction in risk of mortality or other clinically relevant outcomes. The small number of clinical events within existing randomized trials suggests that further well-designed studies of adequate power and duration to measure all-cause mortality, stroke, myocardial infarction, reoperation, and thromboembolic events should be conducted. Future studies should also address cost-effectiveness relative to standard of care.

Randomized Controlled TrialIntravenously Administered Lidocaine and Magnesium During Thyroid Surgery in Female Patients for Better Quality of Recovery After Anesthesia.
Although systemic lidocaine and magnesium have been widely studied as perioperative analgesic adjuvants, they have been rarely evaluated with respect to recovery quality under the same conditions. We compared the quality of recovery 40 (QoR-40) scores of female patients who received intravenous lidocaine, magnesium, and saline during thyroidectomy to investigate their effects on comprehensive recovery from anesthesia. ⋯ Lidocaine administered intravenously during anesthesia led to better quality of postoperative recovery measured by QoR-40 compared with the group C. Magnesium was found to be insufficient to induce any significant improvement with the dose used in the present study.

ReviewMisconceptions Surrounding Penicillin Allergy: Implications for Anesthesiologists.
Administration of preoperative antimicrobial prophylaxis, often with a cephalosporin, is the mainstay of surgical site infection prevention guidelines. Unfortunately, due to prevalent misconceptions, patients labeled as having a penicillin allergy often receive alternate and less-effective antibiotics, placing them at risk of a variety of adverse effects including increased morbidity and higher risk of surgical site infection. ⋯ Current evidence on the structural determinants of penicillin and cephalosporin allergies refutes the misconception of cross-reactivity between penicillins and cefazolin, and there is no clear evidence of an increased risk of anaphylaxis in cefazolin-naive, penicillin-allergic patients. A clinical practice algorithm for the perioperative evaluation and management of patients reporting a history of penicillin allergy is presented, concluding that cephalosporins can be safely administered to a majority of such patients.

Promoting a Restrictive Intraoperative Transfusion Strategy: The Influence of a Transfusion Guideline and a Novel Software Tool.
The effect of neither transfusion guidelines nor decision support tools on intraoperative transfusion has been previously evaluated. The University of Michigan introduced a transfusion guideline in 2009, and in 2011, the Department of Anesthesiology developed a transfusion decision support tool. The primary aim of this study was to assess the associations of the transfusion guideline and the optional use of the software transfusion tool with intraoperative behaviors; pretransfusion hematocrit assessment (whether or not a hematocrit was checked before each red cell unit) and restrictive red cell use (withholding transfusion unless the hematocrit was ≤21%). ⋯ The introduction of a transfusion guideline was independently associated with increased intraoperative pretransfusion hematocrit assessment and restrictive transfusion. The use of a software tool did not further influence either behavior.

Incidence and Risk Factors for Perioperative Cardiovascular and Respiratory Adverse Events in Pediatric Patients With Congenital Heart Disease Undergoing Noncardiac Procedures.
While mortality and adverse perioperative events after noncardiac surgery in children with a broad range of congenital cardiac lesions have been investigated using large multiinstitutional databases, to date single-center studies addressing adverse outcomes in children with congenital heart disease (CHD) undergoing noncardiac surgery have only included small numbers of patients with significant heart disease. The primary objective of this study was to determine the incidences of perioperative cardiovascular and respiratory events in a large cohort of patients from a single institution with a broad range of congenital cardiac lesions undergoing noncardiac procedures and to determine risk factors for these events. ⋯ Intraoperative cardiovascular events and respiratory events in patients with CHD were relatively common. While cardiovascular events were highly associated with cardiovascular status, respiratory events were not associated with cardiovascular status.
