The January issue of Anesthesiology, the journal of the American Society of Anesthesiologists, Inc, marks the debut of a newly designated ‘Education’ section. The new section is designed to highlight clinical material, making it more accessible and relevant for implementation in everyday clinical practice. The issue also features a new study that looks at the effects of beta blockers on surgical outcomes, revealing that the cardioprotective effects of the medication could be compromised by acute surgical anemia.
Beta blockers are used to treat a variety of conditions, including high blood pressure, heart attack, glaucoma and migraines. To determine if there is a significant interaction between the hemoglobin level and beta blocker effect, Dr. Beattie and colleagues performed a retrospective review of 4,378 noncardiac surgery patients at Toronto General Hospital from March 2005 to June 2006. The review revealed that major cardiac complications and death rates were increased for patients treated with beta blockers who experienced more than a 35 percent drop in blood count (or hemoglobin). Researchers discovered that treatment with beta blockers was not harmful to patients if blood loss remained in a range of 30 to 35 percent.
Anesthesiology is the official journal of the American Society of Anesthesiologists but operates with complete editorial autonomy. With an independent and internationally recognised Editorial Board, the journal leads the specialty in promotion of original research by providing immediate open access to highlighted articles and free access to all published articles 6 months after publication.
