We regret that the article “Perioperative Management of Antithrombotic Therapy: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines” published in the February 2012 supplement of CHEST (2012;141[2][Suppl]:e326S-e350S) contained several errors that have since been corrected in the online article.
On page e329S under the bullet “Bridging dose regimens,” the statements in bullet numbers two and three included references to kilograms in error. The statements should read:
2. A low-dose (prophylactic-dose) heparin regimen involves administering a dose that is used, typically, to prevent postoperative VTE (eg, enoxaparin 30 mg bid or 40 mg daily, dalteparin 5,000 International Units daily, UFH 5,000-7,500 International Units bid).
3. An intermediate-dose regimen has recently been studied for bridging and is intermediate in anticoagulant intensity between high- and low-dose regimens (eg, enoxaparin 40 mg bid).
On page e340S in section 3.6 in the upper half of the right column, some of the phrasing and references has been corrected. The changes now reflected in the online article are shown in bold as follows: “… or need for blood transfusion.175 Other observational studies have also found a reduction in cardiovascular events and overall mortality in patients who continue ASA prior to CABG surgery176or start ASA after surgery.43
Finally, on page e349S, references 175 and 176 were incorrectly ordered. In the corrected file online, the original reference 175 is now 176 and vice versa.
