[Frontiers of blood transfusion for critical bleeding: preface and comments]

Area of Science:

• Anesthesiology
• Transfusion Medicine
• Critical Care Medicine

Context:

• Annual surveys (1999-2002) in Japanese Society of Anesthesiologists (JSA)-certified hospitals identified massive bleeding as a primary cause of intraoperative cardiac arrest.
• These surveys indicated underutilization of type-specific and emergent O-type blood transfusions.
• Poor prognosis, including death and permanent brain damage, was associated with critical bleeding events.

Purpose:

• To address the underutilization of appropriate blood transfusions in critical bleeding situations.
• To reduce the incidence of intraoperative cardiac arrest and improve patient prognosis.
• To encourage the development of institutional emergency blood transfusion guidelines.

Summary:

• Guidelines for managing critical bleeding were published by the JSA and the Japan Society of Transfusion Medicine and Cell Therapy in 2007.
• Further guidelines for critical bleeding management in obstetrics were released by five academic societies in 2010.
• Hospitals are encouraged to create institutional guidelines based on these national recommendations.

Impact:

• Aims to decrease the occurrence of critical bleeding during surgery.
• Seeks to improve survival rates and neurological outcomes for patients experiencing severe hemorrhage.
• Promotes standardized and evidence-based transfusion protocols in critical care settings.
