Post-Operative Fiuid Therapy Essay\

Body fluids are so important to the basic physiology of body function. Water is the most abundant single consistent of the body and is the medium in which all metabolic reactions occur. Post-operative fluid and electrolyte therapy is an integral component of anaesthetic management and it can playa critical role in surgical outcome. Replacement of water, ions, protein and or electrolytes is necessary to overcome pathophysiologic effects of operations and to treat any underlying or associated medical disorders complicated by body fluid dearrangment depending on the patient and procedure. Fluid compartments can he divided into the following:I. extracellular fluid compartment.2. Intracellular fluid compartment.Extracellular compartment divided into:• Interstitial fluid. • Plasma.• Third space (fluids in the cerebrospinal fluid, GIT, fluid in the potential space). Intravenous fluid therapy may consist of infusions of crystalloids, colloid orcompensation of both. Colloid solution maintain plasma colloid oncotie pressure and remam intravascular. Crystalloids solution rapidly equilibrate with and distribute througthout the entire extracellular fluid spaces.
