Perioperative blood transfusion carries numerous potential risks concerning the transmission of infective diseases and immunodepression that can facilitate the occurrence of postoperative infectious complications. Explanation of connections between perioperative blood transfusion and postoperative septic complication worldwide is not well documented. Many studies have described a correlation between perioperative blood transfusions and postoperative infections. On the contrary, other studies indicate that factors influencing the need for blood transfusions during surgery have a greater bearing than blood transfusion per se on the occurrence of postoperative complications. ⋯ Blood transfusions independently affected the incidence of wound infections in patients who underwent oesophageal resection for primary cancer.
