[Preoperative blood ordering in elective colon surgery: requirement or routine?]

Area of Science:

• Surgical Oncology
• Transfusion Medicine
• Anesthesiology

Context:

• Preoperative blood ordering for elective colon surgery is common, yet often not justified by actual transfusion needs.
• This practice leads to inefficient resource allocation and potential risks associated with unnecessary transfusions.

Purpose:

• To analyze transfusion rates in elective colon surgery patients.
• To identify clinical and surgical factors associated with perioperative blood transfusion.

Summary:

• A retrospective study analyzed 457 patients undergoing elective colon surgery between 2007-2012.
• Only 16.2% of patients received perioperative transfusions.
• Factors significantly associated with transfusion included preoperative hemoglobin <10 g/dL, COPD, oral anticoagulant use, and surgical duration >120 minutes.

Impact:

• Identifies that the likelihood of perioperative transfusion in elective colon surgery is low.
• Highlights preoperative hemoglobin <10 g/dL as the most significant factor predicting transfusion needs.
• Suggests pre-operative treatment for patients with low hemoglobin to optimize surgical scheduling and reduce transfusion rates.
