Third space loss
Third space loss refers to the loss of plasma fluid into the interstitial space as a result of tissue
trauma and can be estimated based on the nature of the surgery:
• 2-5 cc/kg/hr for minimal surgical trauma (orthopedic surgery)
• 5-10 cc/kg/hr for moderate surgical trauma (bowel resection)
• 10-15 cc/kg/hr for major surgical trauma (abdominal aortic aneurysm repair)
