Perioperative fluid therapy and intraoperative blood loss in children

Area of Science:

• Pediatric Anesthesiology
• Intravenous Fluid Therapy
• Pediatric Surgery

Background:

• Children have distinct physiological differences in body water and blood volume compared to adults.
• Intravenous fluid type, amount, and tonicity are critical considerations in pediatric anesthesia.
• Understanding fluid and blood administration is essential for safe pediatric surgical care.

Purpose of the Study:

• To review the physiological basis of fluid and blood administration in pediatric surgery.
• To discuss historical context and recent advancements in pediatric fluid therapy and blood management.
• To highlight key considerations such as hyponatremia risk and glucose requirements.

Main Methods:

• A comprehensive PUBMED search was conducted for English-language articles.
• Keywords included 'children', 'intravenous fluid therapy', 'crystalloids', 'colloids', 'fluid homeostasis', 'Starling equation', 'Donnan effect', 'blood loss', 'estimation of blood loss', 'blood management program'.
• The review synthesizes findings on physiological principles and clinical practices.

Main Results:

• The review details the physiological underpinnings of fluid and blood administration in pediatric patients.
• It examines the historical evolution and current understanding of fluid homeostasis, including the Starling equation and Donnan effect.
• Current concepts in pediatric blood transfusion and management of blood loss are discussed.

Conclusions:

• Optimal anesthetic management in pediatric surgery necessitates a thorough understanding of fluid and blood administration principles.
• Consideration of pediatric-specific physiology, risks like hyponatremia, and glucose needs is paramount.
• Evidence-based practices in blood management programs are crucial for improving outcomes.
