Define Requirements of Fluid in Postoperative Nutritional Care
Extensive fluid losses may occur through vomiting, haemorrhage, diesis, excudate, fever and sweating after a surgery. An adequate fluid intake is, therefore, required to meet the increased needs. Fluids may be provided by intravenous therapy initially but oral intake should begin as soon as possible. The fluid intake should be sufficient to avoid dehydration on one hand and intoxication on the other.
